Description

The present invention relates to a consumer device, a power consumption management device, a power consumption management system, a power consumption management method, and a power consumption management program, and in particular, a consumer device, a power consumption management device, and a power control device that suppress power consumption in a power demand facility. The present invention relates to a consumption management system, a power consumption management method, and a power consumption management program.

Conventionally, a system for managing power consumption in a power demand facility has been developed so that the power consumption in a power demand facility such as a general home or an office is suppressed when the power demand and supply are tight.

For example, Patent Document 1 (JP 2012-205358 A) discloses the following technique. That is, the power management system includes a holding unit that holds a participant list regarding a community including a plurality of pre-registered participants, a determination unit that determines whether or not to execute power reduction control, and a power reduction control execution unit. When the determination unit determines that it is necessary, the selection unit that selects one or more target persons for power reduction control from the plurality of participants included in the participant list, and the selection unit. A control unit that executes power reduction control for the selected target person, and a granting unit that grants a privilege based on the reduced power to the target person for whom the power reduction control has been executed.

In addition, for the purpose of power saving, BEMS (Building Energy Management System) has been introduced to power demand facilities such as buildings.

BEMS is a system for suppressing power consumption in a power demand facility by monitoring the amount of power consumed in the power demand facility and managing the operating state of devices or equipment in the power demand facility.

BEMS is introduced by a business operator called an aggregator, for example. The aggregator provides an energy management support service to a power demand facility in which BEMS is introduced.

JP 2012-205358 A JP, 2013-161144, A

By introducing BEMS to many power demand facilities, grid side operators such as power companies and grid operation companies can easily adjust the overall power demand over a wide range.

For example, when the power supply/demand is predicted to be tight, the system side business operator requests the aggregator to save power in advance. Then, the aggregator makes a power saving request to the customers of the power demanding facilities.

Hereinafter, each of the consumer devices 202A, 202B, 202C is also referred to as a consumer device 202. Each of the high loads 203A, 203B, and 203C is also referred to as a high load 203. Each of the low loads 204A, 204B, and 204C is also referred to as the low load 204. Each of the high load 203 and the low load 204 is also referred to as a load 205.

Although three consumer devices 202 are representatively shown in FIG. 1, a larger number or a smaller number of consumer devices 202 may be provided. Further, although one high load 203 is representatively shown corresponding to the consumer device 202, a larger number or a smaller number of high loads 203 may be provided corresponding to the consumer device 202. Further, although one low load 204 is representatively shown corresponding to the consumer device 202, a larger number or a smaller number of low load 204 may be provided corresponding to the consumer device 202.

The grid-side management device 151 is operated by a power company on the power grid side, a grid operating company, or the like, and transmits a DR (Demand Response) request signal including power management information regarding power consumption to the power consumption management device 101. The power management information is, for example, the DR start timing and the length of the DR period, which are the start timings of the target period of power consumption suppression (hereinafter, also referred to as the DR period), the requested power amount, the power consumption reduction request amount, or At least one of the reduction levels is included. The power management information may include DR end timing, which is the end timing of the DR period, instead of the length of the DR period.

The consumer device 202 is used in a power demanding facility such as a building, a factory, or a general household that receives power from a power company. One consumer device 202 may be provided for each power demand facility, or a plurality of consumer devices 202 may be provided for each power demand facility. A power company is, for example, a power producer or a power retailer.

The consumer device 202 can control one or more loads 205 in the power demand facility. The load 205 is a secondary battery-type electric vehicle and a plug-in hybrid car that use a secondary battery as an energy source, and electric equipment such as lighting, a television, and an air conditioner.

More specifically, the consumer device 202 is a device used in a system such as a BEMS (Building Energy Management System) or a HEMS (Home Energy Management System) for reducing power consumption by controlling the operation of an electric device. And is introduced by, for example, an aggregator.

The power consumption management apparatus 101 is operated by, for example, an aggregator, and communicates with one or a plurality of customer apparatuses 202 to manage power consumption in one or a plurality of power demanding facilities. The power consumption management device 101 is often installed, for example, at a location remote from the power demand facility in which the consumer device 202 is provided.

[Task]
For example, when the power consumption management apparatus 101 receives the DR request signal from the grid side management apparatus 151, the power consumption management apparatus 101 outputs instruction information regarding power consumption to one or more consumer devices based on the power management information included in the received DR request signal. An instruction process for notifying 202 is performed.

More specifically, the power consumption management apparatus 101 sets, for example, 1 or 1 based on the power management information, the power saving period in which the power consumption should be suppressed, and the instruction information indicating the power saving amount as the power saving target. Notify the plurality of consumer devices 202. The power saving target is not limited to the amount of power to be suppressed, and may be a reduction rate or a reduction rate, for example.

When the consumer device 202 receives the instruction information from the power consumption management device 101, whether or not to perform power saving control for one or more loads 205 that can be controlled by the consumer device 202 based on the received instruction information. Make a decision. This determination is performed according to the power saving policy of the consumer device 202, for example. That is, the consumer device 202 independently controls the load 205. Then, the consumer device 202 outputs a control instruction for performing power saving to the load 205 that is determined to be a control target for power saving.

Specifically, the consumer device 202A determines to control the high load 203A in accordance with its own power saving policy, for example, and outputs a control instruction to the high load 203A, but does not control the low load 204A. to decide.

Further, the consumer device 202B determines that the high load 203B is not controlled, for example, according to its own power saving policy, while determining that the low load 204B is controlled and outputs a control instruction to the low load 204B.

Further, the consumer device 202C determines not to control both the high load 203C and the low load 204C according to its own power saving policy, for example.

That is, in this example, since the consumer device 202 makes a determination regarding control for power saving with respect to the load 205, the power saving in the power demanding facility with respect to the instruction information from the power consumption management device 101 is largely performed by the consumer device 202.

With reference to FIG. 4, the storage unit 26 stores a DLC mapping table Tbl1 including information about candidates for a load 205 (hereinafter, also referred to as a target load 205) to be a target of power consumption suppression.

Specifically, in the DLC mapping table Tbl1, one or a plurality of power saving patterns are associated with the IDs of the customer candidates that are the candidates of the customers who should give the power saving instruction. For example, as shown in FIG. 4, in the DLC mapping table Tbl1, one or a plurality of power saving patterns are collected for each ID of a customer candidate that is a candidate of a customer to whom a power saving instruction should be given. The power saving pattern includes an ID of a target load candidate that is a candidate for the target load 205 (hereinafter, also referred to as a target load candidate ID), a curable amount indicating a power amount that the target load candidate can suppress, and the target load candidate. And the control content to be given to.

The storage unit 26 also holds, for example, an address table showing a correspondence relationship between a customer ID and an address of the customer device 202 of the customer.

[Customer selection]
For example, when the load determination unit 25 receives the power management information from the management information acquisition unit 24, the load determination unit 25 acquires the DLC mapping table Tbl1 from the storage unit 26 and selects a customer based on the acquired contents of the DLC mapping table Tbl1.

Specifically, the load determining unit 25 uses one of the following methods to select a target customer that is a power saving target customer from the customer candidates included in the DLC mapping table Tbl1. Note that the DLC mapping table Tbl1 is not limited to the content including a plurality of customer candidates, but may be the content including one customer candidate. In this case, the load determining unit 25 determines, for example, the one customer candidate as the target customer.

For example, the load determination unit 25 selects all the customer candidates in the DLC mapping table Tbl1 as the target customers.

Further, for example, when priority is given to each customer candidate, the load determination unit 25 selects a target customer from the customer candidates according to the priority. Such a priority is given to each customer candidate based on, for example, a contract for each power demand facility.

In addition, for example, the load determination unit 25 selects the target customer from the customer candidates in the DLC mapping table Tbl1 by rotating numbers.

Further, for example, the load determination unit 25 randomly selects a target customer from the customer candidates in the DLC mapping table Tbl1.

In addition, for example, the load determining unit 25 uses the address information of each customer candidate from the customer candidates in the DLC mapping table Tbl1 to determine, for example, a postal code unit, a municipality and address unit, a substation unit, and a transformer unit. , A target customer is selected in units of local areas of the weather forecast or in units of virtually any group.

FIG. 5: is a figure which shows an example of the suppression of the power consumption in the power consumption management system which concerns on the 1st Embodiment of this invention.

With reference to FIG. 5, for example, the load determination unit 25 selects a target customer from among the customer candidates in the DLC mapping table Tbl1 based on the actual value of the past suppression amount in the power demanding facility of each customer candidate. select.

More specifically, for example, the grid-side management device 151 determines the power saving period B and the requested power amount A that is the upper limit value of the power consumption during the power saving period B when power supply and demand are expected to be tight. Then, the system-side management device 151 includes power management information including the start timing of the power saving period B, the length of the power saving period B, and the requested power amount A in the DR request signal and transmits the DR request signal to the power consumption management device 101.

When the management information acquisition unit 24 receives a DR request signal from the grid-side management device 151 via the reception unit 22, the management information acquisition unit 24 acquires power management information from the received DR request signal and outputs the acquired power management information to the load determination unit 25. To do.

For example, when the load determining unit 25 receives the power management information from the management information acquiring unit 24, the load determining unit 25 acquires the start timing of the power saving period B, the length of the power saving period B, and the requested power amount A from the received power management information.

Whether the load determining unit 25 receives, for example, the estimated total amount of electric power C, which is the sum of the estimated values of the amount of electric power consumption in each power demand facility, from the system side management apparatus 151 via the reception unit 22 and the management information acquisition unit 24, Or hold. The assumed total amount of electric power C is, for example, the amount of electric power that is called a baseline when the electric power consumption is not suppressed, and is calculated based on past electric power consumption data and the like.

The result of subtracting the requested power amount A from the estimated total power amount C is the total request suppression amount D, that is, the reduction request amount, which the power consumption management apparatus 101 should request to each of the subordinate consumer devices 202.

Hereinafter, a specific example of selecting the power demand facility and calculating the assumed total suppression amount will be described in detail.

The load determination unit 25 uses, for example, one of the following methods (A1) to (A3) and (B).

In the methods (A1) to (A3), the load determination unit 25 selects the power demanding facility, that is, the target consumer based on the actual value of the past suppression amount in each power demanding facility of the plurality of consumer candidates. To do.

More specifically, the load determination unit 25 collects the amount of suppression actually performed in the past at each power demand facility in a unit of a predetermined time, for example, 30 minutes, and the average value, the dispersion value, or the suppression value for each unit time is calculated. Calculate the maximum value.

(A1) The sum of the average values of the suppression amounts per unit time in the time zone of the power saving period B, for example, in the time zone of 13:00 to 16:00 (hereinafter, also referred to as the average sum) is calculated, and the power having a large average sum is obtained. The power demanding facilities are selected in order from the demanding facilities, and the power demanding facilities are selected until the total of the average sum of the selected N power demanding facilities (N is an integer of 1 or more) exceeds the total requested suppression amount D. As described above, by sequentially selecting the power demanding facilities having the largest average sum, it is possible to enhance the relevance of the selection of the power demanding facilities.

(A2) The sum of the variance values of the suppression amount per unit time in the time zone of the power saving period B, for example, the time zone of 13:00 to 16:00 is obtained, and the power demanding facilities having the smallest sum are sequentially selected, The power demanding facilities are selected until the total of the average sum of the selected N power demanding facilities (N is an integer of 1 or more) exceeds the total requested suppression amount D. In this way, by sequentially selecting the power demanding facilities with the smallest total sum of variance values, it is possible to suppress the occurrence of a situation in which the sum of the restraint amounts at each power demand facility does not exceed the total requested restraint amount D due to the variation of the restraint amounts. You can

(A3) The sum of the maximum values of the suppression amount per unit time in the time zone of the power saving period B, for example, the time zone of 13:00 to 16:00 is obtained, and the power demanding facilities having the highest sum are sequentially selected, The power demanding facilities are selected until the total of the average sum of the selected N power demanding facilities (N is an integer of 1 or more) exceeds the total requested suppression amount D. As described above, by sequentially selecting the power demanding facilities having the largest maximum value, the number of selected power demanding facilities can be further reduced.

In the method (B), the load determining unit 25 selects the power demanding facility, that is, the target consumer based on the prediction.

More specifically, the load determination unit 25 is based on, for example, the past record of the amount of power consumption at the time of the non-suppression request of the power consumption, the weather information when the record is obtained, and the weather forecast information in the power saving period B. Then, the estimated power amount M for each power demand facility in the power saving period B is calculated.

Specifically, the load determination unit 25 calculates the estimated power amount M of the power demanding facility in the power saving period B by predicting the control content of the load 205 in the power demanding facility from the weather forecast information, for example. The estimated total amount of electric power C is obtained by calculating the sum of the estimated amount of electric power M of each power demand facility.

Next, the load determination unit 25 calculates the assumed suppression amount K for each power demand facility based on the control content for the load 205 assumed in the power saving period B and the weather forecast information at the power demand facility, for example. The control content is obtained from the control content for the load 205 at the time of the suppression request acquired from the consumer device 202, for example.

[Determination of target load and control content]
Hereinafter, it is assumed that the load determination unit 25 selects a target customer from the customer candidates using the above method, and as a result, for example, the customer AAA is included in the selected target customers. Then, the case where the load determining unit 25 determines the target load and the control content in the customer AAA will be described.

The load determination unit 25 determines the target load 205 based on the power management information acquired by the management information acquisition unit 24.

Specifically, the load determination unit 25 determines the target load 205 from the target load candidates stored in the storage unit 26 based on the power management information, for example. In addition, the load determining unit 25 determines the control content of the target load 205 based on the power management information, for example.

More specifically, the load determining unit 25 performs the following processing using the DLC mapping table Tbl1. That is, for example, the load determining unit 25 determines the target load 205 so as to satisfy the requested power amount, the power consumption reduction request amount, or the reduction level included in the power management information, and the control content to be given to the target load 205. To decide.

Hereinafter, a case will be described in which the load determination unit 25 determines the target load 205 so as to satisfy the power consumption reduction request amount and also determines the control content to be given to the target load 205.

The requested power amount, the requested power consumption reduction amount, or the reduction level may be determined in advance by contract.

Specifically, the load determining unit 25 uses, for example, the DLC mapping table Tbl1 to select a power-saving pattern (hereinafter referred to as a power-saving pattern that satisfies the reduction request amount from one or a plurality of power-saving patterns corresponding to the selected customer AAA. , Target power saving pattern).

Note that the DLC mapping table Tbl1 may include one power saving pattern corresponding to the customer AAA. In this case, the load determining unit 25 selects, for example, the one power saving pattern as the target power saving pattern.

For example, the load determination unit 25 selects the target power saving pattern from the power saving patterns included in the DLC mapping table Tbl1 using any of the following methods.

That is, the load determining unit 25 selects, for example, all of the power saving patterns corresponding to the customer AAA as the target power saving pattern.

Further, for example, when a priority is given to each power saving pattern in advance, the load determining unit 25 determines the power saving pattern according to the priority. Specifically, for example, the load determining unit 25 selects power saving patterns in descending order of priority, and selects power saving patterns until the total of the curable amounts included in the selected power saving patterns exceeds the reduction request amount. .. Then, the load determination unit 25 determines the selected power saving pattern as the target power saving pattern. Such a priority is given by, for example, a consumer.

Further, for example, the load determination unit 25 determines the power saving pattern according to the size of the restrainable amount. Specifically, the load determining unit 25 selects power saving patterns in order from the largest suppressible amount, and selects the power saving pattern until the total of the suppressible amounts included in the selected power saving patterns exceeds the reduction request amount. Then, the load determination unit 25 determines the selected power saving pattern as the target power saving pattern.

In addition, the load determining unit 25 selects a power saving pattern by, for example, a ring number from the power saving patterns, and determines the selected power saving pattern as the target power saving pattern.

Further, the load determining unit 25 randomly selects a power saving pattern from the power saving patterns, for example, and determines the selected power saving pattern as the target power saving pattern.

For example, the load determining unit 25 uses any one of the above methods, “target load candidate ID: AAA-1, suppressible amount: 100 W, control content: OFF” and “target load candidate ID: AAA-”. 4, controllable amount: 300 W, control content: increase set value by 3° C.” is determined as the target power saving pattern.

The load determining unit 25 generates target load information indicating the determined target load 205 and control information indicating the determined control content. Specifically, the load determining unit 25 acquires the target load candidate ID and the control content from the determined target power saving pattern, and controls the target load information indicating the acquired target load candidate ID and the control content for the target load candidate. And target load control information including the information.

The contents of the target load control information are, for example, "target load ID: AAA-1, control content: off" and "target load ID: AAA-4, control content: increase set value by 3°C".

In addition, the load determining unit 25 acquires the DR start timing and the length of the DR period from the power management information, and generates the DR period information including the acquired DR start timing and the length of the DR period.

The load determining unit 25 refers to the address table in the storage unit 26, for example, and acquires the address of the consumer device 202 of the consumer AAA. The load determining unit 25 outputs the generated target load control information, the DR period information, and the address of the consumer device 202 of the consumer AAA to the transmitting unit 23.

For example, when the transmission unit 23 receives the target load control information and the DR period information and the address of the customer device 202 of the customer AAA from the load determination unit 25, the target load control information and the DR period information are addressed to the received address. A DLC signal including the above is transmitted to the customer device 202 of the customer AAA via the Internet 10.

[Customer equipment]
FIG. 6 is a diagram showing a configuration of a consumer device in the power consumption management system according to the first embodiment of the present invention.

With reference to FIG. 6, the consumer device 202 includes a reception unit 42, a transmission unit 43, a control unit 44, a storage unit 45, a counter 46, and a display unit 47.

The counter 46 in the consumer device 202 counts clock pulses generated by, for example, an oscillation circuit using a crystal oscillator, and holds the counted value. The display unit 47 is, for example, a display, and displays the information to be transmitted to the customer under the control of the control unit 44. The transmission unit 43 can communicate with the load 205 via the LAN 11.

The receiving unit 42 receives, for example, target load information indicating the target load 205, which is the load 205 to be the target of power consumption suppression. Further, the receiving unit 42 receives, for example, control information indicating the control content of the target load 205.

Specifically, for example, when the receiving unit 42 receives a DLC signal from the power consumption management device 101 via the Internet 10, the receiving unit 42 acquires target load control information and DR period information from the received DLC signal, and acquires the target load control. The information and the DR period information are output to the control unit 44.

FIG. 7: is a figure which shows an example of the load control table which the memory|storage part in the consumer device which concerns on the 1st Embodiment of this invention hold|maintains.

With reference to FIG. 7, the storage unit 45 stores a load control table Tbl2 including information on a communication method with one or more loads 205.

Specifically, in the load control table Tbl2, the connection I/F (interface) that is a communication method with the target load 205 and the control method of the target load 205 are the ID of the target load 205 (hereinafter, also referred to as the target load ID). It is summarized by each.

The “connection I/F” indicates a physical interface, for example. The connection I/F includes, for example, "contact", "Ethernet (registered trademark)", and "WiFi (registered trademark)".

The "contact" is, for example, a connection I/F for performing contact signal control. “Ethernet” is a connection I/F for performing wired network control via the LAN 11 according to the Ethernet (registered trademark) standard, for example. “WiFi” is a connection I/F for performing wireless network control via a wireless LAN according to the WiFi standard, for example.

The “control method” indicates, for example, a signal transmission method or an information transmission method for transmitting a signal or information to the load 205 using a physical interface indicated by the connection I/F. The control method includes, for example, “contact signal On/Off”, “standard protocol”, and “maker's original protocol”.

“Contact signal On/Off” is a signal transmission method for transmitting a contact signal for turning on or off a switch of an electric device that is the target load 205 to the load 205, for example.

The “standard protocol” is, for example, an information transmission method for transmitting a control command, which is information for controlling the target load 205, to the target load 205, and specifically, a communication protocol according to the ECHONET Lite (registered trademark) standard. (Hereinafter, also referred to as Econet Protocol). The "standard protocol" is not limited to the ECONET protocol, and may be any protocol used as a standard.

The “manufacturer original protocol” is, for example, for transmitting a control command, which is information for performing control for turning on or off the target load 205, to the LAN contact converter 207 that performs contact signal control for the target load 205. Information transmission method, specifically, a communication protocol conforming to the standard originally created by the manufacturer of the LAN contact converter 207.

The contact signal control is, for example, control using a signal transmission method indicated by “contact signal On/Off”. The network control is, for example, control using an information transmission method indicated by the “standard protocol” or the “maker's original protocol”. The contact signal control can be performed, for example, when the control device and the control device are located in the same facility.

For example, when the LAN contact converter 207 receives a control command from the consumer device 202, the LAN contact converter 207 turns on or off the target load 205 by performing contact signal control based on the received control command.

The control unit 44 suppresses the power consumption of the target load 205 by controlling the target load 205 indicated by the target load information received by the receiving unit 42. The control unit 44 also controls the target load 205 according to the control content indicated by the control information.

Specifically, when the control unit 44 receives the target load control information and the DR period information from the reception unit 42, the control unit 44 performs the following processing.

That is, the control unit 44 acquires the DR start timing and the length of the DR period from the DR period information, and calculates the DR end timing based on the acquired DR start timing and the length of the DR period.

Then, the control unit 44, for example, monitors the count value of the counter 46 and waits until the DR start timing arrives. For example, when the control unit 44 recognizes that the DR start timing has arrived from the count value of the counter 46, the control unit 44 causes the display unit 47 to display a screen indicating that it is the DR period.

Further, the control unit 44 starts controlling the target load 205 at the DR start timing. More specifically, the control unit 44 acquires information regarding the communication method with the target load 205 from the storage unit 45, and controls the target load 205 using the acquired communication method.

Specifically, the control unit 44 acquires the target load ID and the corresponding control content from the target load control information received from the receiving unit 42, for example. More specifically, the control unit 44 acquires, for example, “target load ID: AAA-1, control content: OFF” and “target load ID: AAA-4, control content: increase set value by 3° C.”.

The control unit 44 also refers to the load control table Tbl2 in the storage unit 45, for example. Then, the control unit 44 acquires the information on the connection I/F and the control method corresponding to the target load ID from the load control table Tbl2 based on the target load control information, for example.

Specifically, the control unit 44, for example, as a connection I/F and a control method corresponding to “target load ID: AAA-1, control content: OFF” and “contact” and “contact signal On/Off”, respectively. To get.

Further, the control unit 44 acquires, for example, “Ethernet” and “standard protocol” as the connection I/F and control method corresponding to “target load ID: AAA-4, control content: increase set value by 3° C.”, respectively. To do.

Then, for example, at the DR start timing, the control unit 44 sends a contact signal or a control command to the load 205 based on the target load ID and the corresponding control content, and the connection I/F and the control method corresponding to the target load ID. Send.

Specifically, the control unit 44 holds, for example, the address of the target load 205 corresponding to the target load ID. The target load ID may be the address itself of the target load 205.

For example, at the DR start timing, the control unit 44 turns off the switch based on "target load ID: AAA-1, control content: off" and the corresponding "contact" and "contact signal On/Off". To the load 205A of "AAA-1". As a result, the control unit 44 starts the control for turning off the switch of the load 205A.

In addition, for example, at the DR start timing, the control unit 44, based on “target load ID: AAA-4, control content: increase set value by 3° C.” and corresponding “Ethernet” and “standard protocol”, A control command indicating "increase the set value by 3° C." is transmitted to the load 205D of "AAA-4" via the transmission unit 43 and the LAN 11 according to the Ethernet standard. As a result, the control unit 44 starts control to raise the set temperature of the load 205D by 3°C.

For example, after controlling the target load 205 based on the target load control information, the control unit 44 performs the following processing when recognizing that the DR end timing has arrived from the count value of the counter 46, for example.

That is, the control unit 44 ends the control of the target load 205 at the DR end timing, for example.

Specifically, for example, in order to return the control state of the load 205A to the state before the DR start timing, the control unit 44 has a "contact point" corresponding to "target load ID: AAA-1, control content: OFF". A contact signal for turning on the switch is transmitted to the load 205A of "AAA-1" based on "and On/Off of contact signal".

Further, for example, in order to return the control state of the load 205D to the state before the DR start timing, the control unit 44 corresponds to “target load ID: AAA-4, control content: increase set value by 3° C.”. Based on Ethernet and standard protocol, a control command indicating "decrease setting value by 3°C" is transmitted to the load 205D of "AAA-4" via the transmission unit 43 and LAN 11 according to the Ethernet standard.

Here, for example, in the case where the target load 205 is a device that generates heat such as an electric heater, a situation in which the electric heater falls over after the control unit 44 switches off the electric heater at the DR start timing. Assume

In such a situation, when the control unit 44 turns on the switch of the electric heater at the DR end timing, the electric heater may generate heat in the overturned state.

Therefore, the process of returning the control state of the load 205 to the state before the DR start timing at the DR end timing is not limited to the configuration performed by the control unit 44, and may be performed manually by a consumer or the like.

Further, the control unit 44 outputs, for example, information regarding the end of the DR period. Specifically, the control unit 44 causes the display unit 47 to display a screen indicating that the DR period has ended, for example.

Next, the consumer device 202 transmits a contact signal for turning off the switch to the load 205A corresponding to the target load ID based on the acquired target load control information, the connection I/F, and the control method (step). S114).

In addition, the consumer device 202, based on the acquired target load control information, the connection I/F, and the control method, sends a control command indicating “increase the set value by 3° C.” to the target load ID according to the Ethernet standard. It transmits to the corresponding load 205D (step S116).

Next, the consumer device 202 recognizes from the count value of the counter 46 that the DR end timing has arrived (step S118).

FIG. 10: is a figure which shows the structure of the modification of the consumer device in the power consumption management system which concerns on the 1st Embodiment of this invention.

Referring to FIG. 10, consumer device 212, which is a modified example of consumer device 202, does not include counter 46 as compared with consumer device 202 shown in FIG. 6.

The operations of the reception unit 42, the transmission unit 43, the control unit 44, the storage unit 45, and the display unit 47 in the consumer device 212 are the same as those of the reception unit 42, the transmission unit 43, the control unit 44, and the storage unit in the consumer device 202 illustrated in FIG. It is similar to the unit 45 and the display unit 47, respectively.

Referring again to FIG. 9, when the load determining unit 25 receives the power management information from the management information acquiring unit 24, for example, the load determining unit 25 determines the target power saving pattern from the power saving patterns included in the DLC mapping table Tbl1.

The load determination unit 25 acquires the target load candidate ID and the control content from the determined target power saving pattern, and the target load including the target load information indicating the acquired target load candidate and the control information indicating the control content for the target load candidate. Generate control information.

The load determining unit 25 also acquires the DR start timing and the length of the DR period from the power management information, and calculates the DR end timing based on the acquired DR start timing and the length of the DR period. Then, the load determination unit 25, for example, monitors the count value of the counter 27 and waits until the DR start timing arrives.

For example, when the load determining unit 25 recognizes that the DR start timing has arrived from the count value of the counter 27, the load determining unit 25 outputs the generated target load control information and the address of the consumer device 202 of the consumer AAA to the transmitting unit 23. ..

For example, when the transmission unit 23 receives the target load control information and the address of the customer device 202 of the customer AAA from the load determination unit 25, the transmission unit 23 sets the received address as a destination and sends the DLC signal including the target load control information to the customer AAA. To the consumer device 212 of the above via the Internet 10.

Further, for example, when the load determining unit 25 recognizes that the DR end timing has arrived from the count value of the counter 27 after outputting the target load control information and the address to the transmitting unit 23, the load determining unit 25 releases the power saving command and the cancel command. The address of the customer device 212 of the customer AAA is output to the transmission unit 23.

For example, when the transmission unit 23 receives the cancellation command and the address of the consumer device 212 of the customer AAA from the load determination unit 25, the cancellation signal including the cancellation command is addressed to the received address and the consumer device of the consumer AAA is received. 212 to the Internet via the Internet 10.

Referring to FIG. 10 again, consumer device 212 waits, for example, until it receives a DLC signal from power consumption management device 111 via Internet 10.

When receiving the DLC signal from the power consumption management apparatus 111 via the Internet 10, the reception unit 42 acquires the target load control information from the received DLC signal and outputs the acquired target load control information to the control unit 44.

For example, when the control unit 44 receives the target load control information from the reception unit 42, the control unit 44 causes the display unit 47 to display a screen indicating that it is the DR period.

Then, the control unit 44 acquires the target load ID and the corresponding control content from the target load control information received from the receiving unit 42, for example.

The control unit 44 also refers to the load control table Tbl2 in the storage unit 45, for example. Then, the control unit 44 acquires, for example, the connection I/F and the control method corresponding to the target load ID based on the target load control information.

Then, the control unit 44 transmits a contact signal or a control command to the load 205 based on, for example, the target load ID and the corresponding control content, and the connection I/F and the control method corresponding to the target load ID.

In addition, for example, when receiving a cancellation signal from the power consumption management device 111 via the Internet 10, the reception unit 42 acquires a cancellation command from the received cancellation signal, and outputs the acquired cancellation command to the control unit 44.

For example, the control unit 44 ends the control of the target load 205 when receiving the release command from the reception unit 42. Further, the control unit 44 outputs, for example, information regarding the end of the DR period, and more specifically, causes the display unit 47 to display a screen indicating that the DR period has ended.

The process of returning the control state of the load 205 to the state before the DR start timing at the DR end timing is not limited to the configuration performed by the control unit 44, and may be performed manually by a consumer or the like.

[Operation of Modification 1]
FIG. 11: is a figure which shows the other example of the sequence of the power consumption suppression process in the power consumption management system which concerns on the 1st Embodiment of this invention.

With reference to FIG. 11, first, the grid-side management device 151 predicts the power demand, determines that power consumption should be suppressed when there is a high possibility that the power demand and supply will be tight, and the power management information is displayed.

Next, the power consumption management apparatus 111 generates the target load control information including the target load candidate ID included in the determined target power saving pattern and the corresponding control content, and also performs the following processing. That is, the power consumption management apparatus 111 acquires the DR start timing and the length of the DR period from the power management information, and calculates the DR end timing based on the acquired DR start timing and the length of the DR period. Then, the power consumption management apparatus 111 waits until the DR start timing (step S156).

Next, the power consumption management apparatus 111 recognizes that the DR start timing has arrived from the count value of the counter 27 (step S158).

Next, the power consumption management apparatus 111 transmits the DLC signal including the generated target load control information to the consumer device 212 (step S160).

Next, when the consumer device 212 receives the DLC signal from the power consumption management device 111, the consumer device 212 acquires the target load control information from the received DLC signal. Then, the consumer device 212 acquires the connection I/F and the control method corresponding to the target load ID based on the acquired target load control information and the content of the load control table Tbl2 (step S162).

Next, the consumer device 212 transmits a contact signal for turning off the switch to the load 205A corresponding to the target load ID, based on the acquired target load control information, the connection I/F, and the control method (step). S164).

To the load 205D to be operated (step S166).

Next, the power consumption management apparatus 111 recognizes that the DR end timing has arrived from the count value of the counter 27 (step S168).

Next, the power consumption management apparatus 111 transmits the cancellation|release signal containing a cancellation|release command to the consumer device 212 (step S170).

Next, when the consumer device 212 receives the cancellation signal from the power consumption management device 111, the consumer device 212 acquires a cancellation command from the received cancellation signal, and performs the following processing based on the acquired cancellation command. That is, in order to return the control state of the load 205A to the state before the DR start timing, the consumer device 212 has a contact for turning on the switch based on the target load control information and the connection I/F and the control method. The signal is transmitted to the load 205A corresponding to the target load ID (step S172).

Further, the consumer device 212 returns the control state of the load 205D to the state before the DR start timing, based on the target load control information, the connection I/F, and the control method, “decrease the set value by 3° C.” According to the Ethernet standard, is transmitted to the load 205D corresponding to the target load ID (step S174).

As described above, with the configuration in which the power consumption management apparatus 111 manages the DR period, the configuration for managing the DR period, such as the counter 46 in the consumer device 212, can be eliminated, so that the cost of the consumer device 212 can be reduced. Can be down. Further, since the amount of information included in the DLC signal can be reduced, it is possible to reduce the burden of information transmission on the communication line.

Specifically, when the control unit 44 receives the target load control information and the DR period information from the reception unit 42, the control unit 44 performs the following processing.

That is, the control unit 44 acquires the target load ID and the corresponding control content from the target load control information, for example. Here, the control unit 44 acquires, for example, "target load ID: AAA-2, control content: OFF" and "target load ID: AAA-4, control content: increase set value by 3°C".

The control unit 44 also refers to the load control table Tbl2 in the storage unit 45, for example. Then, the control unit 44 acquires the information on the connection I/F and the control method corresponding to the target load ID from the load control table Tbl2 based on the target load control information, for example.

Specifically, the control unit 44 acquires, for example, "Ethernet" and "maker-specific protocol" as the connection I/F and control method corresponding to "target load ID: AAA-2, control content: OFF", respectively. ..

Further, the control unit 44 acquires, for example, “Ethernet” and “standard protocol” as the connection I/F and control method corresponding to “target load ID: AAA-4, control content: increase set value by 3° C.”, respectively. To do.

[LAN contact converter 207]
FIG. 13: is a figure which shows the structure of the LAN contact converter in the modification of the power consumption management system which concerns on the 1st Embodiment of this invention.

With reference to FIG. 13, in the power consumption management system according to the second modification, LAN contact converter 207 includes a counter 61, a control unit 62, and a receiving unit 63. The operation of the counter 61 is similar to that of the counter 46 in the consumer device 202 shown in FIG.

Upon receiving the control command A2 from the consumer device 222, the reception unit 63 of the LAN contact converter 207 outputs the received control command A2 to the control unit 62.

Upon receiving the control command A2 from the receiving unit 63, the control unit 62 acquires the target load control information and the DR period information from the received control command A2.

The control unit 62 acquires the DR start timing and the length of the DR period from the DR period information, and calculates the DR end timing based on the acquired DR start timing and the length of the DR period.

Then, the control unit 62 monitors, for example, the count value of the counter 61 and waits until the DR start timing arrives. For example, when the control unit 62 recognizes that the DR start timing has arrived from the count value of the counter 61, the control unit 62 starts controlling the target load 205.

More specifically, the control unit 62 sends a contact signal for turning off the switch to the load corresponding to the target load ID, based on “target load ID: AAA-2, control content: OFF” indicated by the target load control information. 205B. As a result, the control unit 62 starts control to turn off the switch of the load 205B.

After controlling the target load 205B based on the target load control information, for example, the control unit 62 recognizes that the DR end timing has come from the count value of the counter 61, and then performs the following process.

That is, the control unit 62 ends the control of the target load 205B at the DR end timing, for example.

Specifically, for example, in order to return the control state of the load 205B to the state before the DR start timing, the control unit 62 indicates “target load ID: AAA-2, control content: off” indicated by the target load control information. Based on the above, the contact signal for turning on the switch is transmitted to the load 205B corresponding to the target load ID.

[Load 205D]
FIG. 14: is a figure which shows the structure of the load in the modification of the power consumption management system which concerns on the 1st Embodiment of this invention.

With reference to FIG. 14, in the power consumption management system according to the second modification, the load 205D includes a counter 71, a control unit 72, and a receiving unit 73. The operation of the counter 71 is similar to that of the counter 46 in the consumer device 202 shown in FIG.

Upon receiving the control command A4 from the consumer device 222, the receiving unit 73 in the load 205D outputs the received control command A4 to the control unit 72.

Upon receiving the control command A4 from the receiving unit 73, the control unit 72 acquires the target load control information and the DR period information from the received control command A4.

The control unit 72 acquires the DR start timing and the length of the DR period from the DR period information, and calculates the DR end timing based on the acquired DR start timing and the length of the DR period.

Then, the control unit 72, for example, monitors the count value of the counter 71 and waits until the DR start timing arrives. When recognizing that the DR start timing has arrived from the count value of the counter 71, for example, the control unit 72 starts controlling its own load 205D.

More specifically, the control unit 72 increases the set value of its own load 205D by 3° C. based on “target load ID: AAA-4, control content: increase set value by 3° C.” indicated by the target load control information. By performing the process, the control for suppressing its own power consumption is started.

For example, after controlling the own load 205D based on the target load control information, the control unit 72 performs the following processing when recognizing that the DR end timing has arrived from the count value of the counter 71, for example.

That is, the control unit 72 ends control of its own load 205D at the DR end timing, for example.

Specifically, for example, in order to return the control state of the load 205D of the control unit 72 to the state before the DR start timing, the control unit 72 indicates “target load ID: AAA-4, control content: By increasing the set value by 3° C.”, the control for suppressing the own power consumption is ended by performing the process of decreasing the set value of the own load 205D by 3° C.

[Operation of Modification 2]
FIG. 15 is a diagram showing another example of the sequence of the power consumption suppressing process in the power consumption management system according to the first embodiment of the present invention.

Referring to FIG. 15, first, the grid-side management device 151 predicts the power demand, determines that the power consumption should be suppressed when the power demand and supply are likely to be tight, and determines the power management information. The DR request signal including the signal is transmitted to the power consumption management apparatus 101 (step S502).

Next, the power consumption management apparatus 101 determines a target power saving pattern from the power saving patterns included in the DLC mapping table Tbl1 based on the power management information included in the received DR request signal (step S504).

Next, the power consumption management apparatus 101 generates the target load control information including the target load candidate ID included in the determined target power saving pattern and the corresponding control content, and also generates the DR period information from the power management information. Then, the power consumption management apparatus 101 transmits the generated DLC signal including the target load control information and the DR period information to the consumer device 222 (step S506).

Next, when the consumer device 222 receives the DLC signal from the power consumption management device 101, the consumer device 222 acquires the target load control information and the DR period information from the received DLC signal. Then, the consumer device 222 acquires the connection I/F and the control method corresponding to the target load ID based on the acquired target load control information and the content of the load control table Tbl2 (step S508).

Next, the consumer device 222 generates the control command A2 from the target load control information and the DR period information, and generates it based on the connection I/F and the control method corresponding to the “target load ID: AAA-2”. According to the Ethernet standard, the control command A2 is transmitted to the LAN contact converter 207 that performs contact signal control for the load 205B corresponding to the target load ID (step S510).

Further, the consumer device 222 generates the control command A4 from the target load control information and the DR period information, and based on the connection I/F and the control method corresponding to the “target load ID: AAA-4”, the generated control. The command A4 is transmitted to the load 205D corresponding to the target load ID according to the Ethernet standard (step S512).

Next, when the LAN contact converter 207 receives the control command A2 from the consumer device 222, the LAN contact converter 207 acquires the target load control information and the DR period information from the received control command A2. Then, the LAN contact converter 207 acquires the DR start timing from the DR period information and waits until the DR start timing (step S514).

When the load 205D receives the control command A4 from the consumer device 222, the load 205D acquires the target load control information and the DR period information from the received control command A4. Then, the load 205D acquires the DR start timing from the DR period information and waits until the DR start timing (step S516).

Next, the LAN contact converter 207 recognizes from the count value of the counter 61 that the DR start timing has arrived (step S518).

Further, the load 205D recognizes that the DR start timing has arrived from the count value of the counter 71 (step S520).

Next, the LAN contact converter 207 transmits a contact signal for turning off the switch to the load 205B corresponding to the target load ID based on the acquired target load control information (step S522).

In addition, the load 205D starts control to suppress its own power consumption by performing a process of increasing its own set value by 3° C. based on the acquired target load control information (step S524).

Next, the LAN contact converter 207 recognizes from the count value of the counter 61 that the DR end timing has arrived (step S526).

Further, the load 205D recognizes that the DR end timing has arrived from the count value of the counter 71 (step S528).

Next, the LAN contact converter 207 corresponds the contact signal for turning on the switch to the target load ID based on the target load control information in order to return the control state of the load 205B to the state before the DR start timing. To the load 205B to be operated (step S530).

Also, the load 205D reduces its own power consumption by performing a process of lowering its own set value by 3° C. based on the target load control information in order to return its control state to the state before the DR start timing. The suppression control ends (step S532).

As described above, with the configuration in which the target load 205 manages the DR period, the load of management processing in the DR period can be distributed to the target load 205.

The power consumption management device according to the first embodiment of the present invention is configured to transmit the target load information and the control information to the consumer device 202, but the configuration is not limited to this. The power consumption management apparatus 101 may be configured not to transmit the control information to the consumer device 202. In this case, the control content of the target load 205 is determined by the consumer device 202, for example.

By the way, in the target period of the power saving request, the power consumption may not be suppressed in the power demanding facility of the customer in accordance with the power saving request. In such a case, sufficient power saving may not be performed and power supply and demand may be tight.

On the other hand, the consumer device according to the first embodiment of the present invention can control one or a plurality of loads 205 in the power demanding facility. The receiving unit 42 receives target load information indicating the target load 205, which is the load 205 to be the target of power consumption suppression. The control unit 44 suppresses the power consumption of the target load 205 by controlling the target load 205 indicated by the target load information received by the receiving unit 42.

In this way, for example, the configuration that controls the target load 205 indicated by the target load information received from the aggregator-side device allows the aggregator-side device to specify the target load 205 in the power demand facility of the consumer. Therefore, it is possible to more reliably suppress the power consumption in the power demanding facility of the customer. As a result, it is possible to more reliably avoid the situation where the power supply and demand are tight. Further, the consumer device 202 only needs to have a configuration that controls the target load 205 according to the target load information, and thus the configuration of the consumer device 202 can be simplified.

Here, instead of the consumer device 202 independently controlling the load 205, for example, when the power consumption management device 101 remotely and remotely controls the load 205, the load 205 communicates with the power consumption management device 101. It must be possible.

Specifically, as a method for controlling the load 205, for example, a method using contact signal control, network control, and remote control can be considered.

More specifically, contact signal control is possible when the device that performs control and the device that receives control are located in the same power demand facility. Therefore, for example, it is difficult for the power consumption management apparatus 101 installed at a location remote from the power demanding facility to independently control the load 205 provided in the power demanding facility using the contact signal.

In addition, since the load 205 in the power demand facility often supports the ECONET protocol, the ECONET protocol is used for communication between the consumer device 202 and the load 205 in the power demand facility.

On the other hand, the communication protocol supported by the power consumption management apparatus 101 is often a communication protocol different from the econet protocol. That is, since there is no standard protocol for the power consumption management device 101 and the load 205 to communicate with each other, it is difficult for the power consumption management device 101 to remotely control the load 205 by network control. ..

Further, the remote control is, for example, control using infrared rays or radio waves. For example, even if the power consumption management apparatus 101 installed at a location remote from the power demand facility transmits infrared rays or radio waves, the transmitted infrared rays or radio waves can reach the load 205 provided in the power demand facility. Is often difficult. Therefore, it is difficult for the power consumption management apparatus 101 to remotely control the load 205 by remote control.

That is, since the contact signal control, the network control, and the remote control are methods that can control the load 205 in a limited area near the power demanding facility, the power consumption management apparatus 101 independently and remotely controls the load 205 by remote control. Controlling 205 is difficult.

On the other hand, in the consumer device according to the first embodiment of the present invention, the power consumption management device 101 is remotely controlled by the configuration that controls the target load 205 indicated by the target load information received from the aggregator side device. The load 205 can be controlled independently.

Further, in the consumer device according to the first embodiment of the present invention, the reception unit 42 further receives control information indicating the control content of the target load 205. The control unit 44 controls the target load 205 according to the control content indicated by the control information.

In this way, for example, with the configuration in which the target load 205 is controlled by the content indicated by the control information received from the aggregator-side device, the aggregator-side device specifies the control content of the target load 205 in the power demand facility. Therefore, it is possible to more reliably suppress the power consumption in the power demanding facility of the customer. Further, the consumer device 202 may be configured to control the target load 205 according to the control information, and thus the configuration of the consumer device 202 can be simplified. Further, for example, it is possible to increase the variation of the control for the target load 205 in the aggregator side device. As a result, the target load 205 can be delicately controlled, and the amount of power consumption suppression can be adjusted more finely. Further, since the control can be performed according to the type of the target load 205, it is possible to mitigate the harmful effect of power saving in the power demanding facility of the consumer. Specifically, for example, by controlling the air conditioner to change the set value instead of turning it off, it is possible to reduce the degree of discomfort in the living environment while suppressing power consumption.

Further, in the consumer device according to the first embodiment of the present invention, the storage unit 45 stores information regarding a communication method with one or a plurality of loads 205. The control unit 44 acquires information regarding the communication method with the target load 205 from the storage unit 45, and controls the target load 205 using the acquired communication method.

With such a configuration, for example, even when the device on the aggregator side cannot directly communicate with the target load 205, the device on the aggregator side can communicate with the target load 205 via the consumer device 202. Therefore, the target load 205 can be easily controlled.

In the consumer device according to the first embodiment of the present invention, the control unit 44 starts controlling the target load 205 at the start timing of the DR period, which is the target period for suppressing power consumption. Then, the control unit 44 ends the control of the target load 205 at the end timing of the DR period, or outputs information regarding the end of the DR period.

With such a configuration, the control of the target load 205 can be automatically returned to the state before the start timing of the DR period, so that the burden on the consumer can be reduced. Further, it is possible to notify that the control for suppressing the power consumption of the target load 205 has ended.

Further, the power consumption management device according to the first embodiment of the present invention manages power consumption in a power demanding facility. The management information acquisition unit 24 acquires power management information regarding power consumption from the power system side. The load determination unit 25 determines the target load 205, which is the load to be the target of power consumption suppression, based on the power management information acquired by the management information acquisition unit 24. Then, the transmission unit 23 transmits the target load information indicating the target load 205 determined by the load determination unit 25 to the consumer device 202.

With such a configuration, the target load 205 in the power demand facility of the consumer can be specified in the power consumption management device 101, so that the power consumption in the power demand facility of the consumer can be suppressed more reliably. .. As a result, it is possible to avoid a situation where the power supply and demand are tight.

Further, in the power consumption management device according to the first embodiment of the present invention, the storage unit 26 stores information regarding candidates for the target load 205. Then, the load determination unit 25 determines the target load 205 from the candidates for the target load 205 in the storage unit 26 based on the power management information.

With such a configuration, the target load 205 can be specified from among the candidates for the target load 205 in a plurality of power demanding facilities, so that the optimum power consumption can be suppressed as the entire power consumption management system 301. it can. In addition, since a candidate for the target load 205 can be set in the power consumption management apparatus 101 by the consumer, for example, the candidate for the target load 205 is limited to the load 205 that allows the consumer to control the power consumption. You can As a result, it is possible to reduce the inconvenience of the customer in the power demanding facility during the target period of the power saving request.

In addition, in the power consumption management device according to the first embodiment of the present invention, the load determination unit 25 further determines the control content of the target load 205 based on the power management information. Then, the transmission unit 23 further transmits control information indicating the control content determined by the load determination unit 25 to the consumer device 202.

With such a configuration, it is possible to specify the control content of the target load 205 in the power demanding facility, so that it is possible to more reliably suppress the power consumption in the power demanding facility of the consumer. Further, for example, the control content of the target load 205 in each of a plurality of power demanding facilities can be specified, so that the power consumption management system 301 as a whole can suppress power consumption more optimally. Further, for example, it is possible to increase the variation of the control for the target load 205 in the aggregator side device. As a result, the target load 205 can be delicately controlled, and the amount of power consumption suppression can be adjusted more finely. Further, since the control can be performed according to the type of the target load 205, it is possible to mitigate the harmful effect of power saving in the power demanding facility of the consumer. Specifically, for example, by controlling the air conditioner to change the set value instead of turning it off, it is possible to reduce the degree of discomfort in the living environment while suppressing power consumption.

In addition, in the power consumption management system according to the first embodiment of the present invention, the power consumption management apparatus 101 outputs the target load information indicating the target load 205, which is the load 205 to be the target of power consumption suppression, to the consumer device. Send to 202. Then, the consumer device 202 receives the target load information from the power consumption management device 101, and controls the target load 205 indicated by the received target load information to suppress the power consumption of the target load.

In this way, by the configuration in which the consumer device 202 controls the target load 205 indicated by the target load information transmitted from the power consumption management device 101, the power consumption management device 101 controls the target load 205 in the power demand facility of the consumer. Since it can be designated, it is possible to more reliably suppress the power consumption in the power demanding facility of the consumer. As a result, it is possible to avoid a situation where the power supply and demand are tight. Further, the consumer device 202 only needs to have a configuration that controls the target load 205 according to the target load information, and thus the configuration of the consumer device 202 can be simplified.

Next, another embodiment of the present invention will be described with reference to the drawings. It should be noted that the same or corresponding parts in the drawings are designated by the same reference numerals and the description thereof will not be repeated.

Then, the power consumption management apparatus 101 uses the acquired deletion target load ID to delete the suppressible amount and control content corresponding to the deletion target load ID from the DLC mapping table Tbl1 in the storage unit 26 (step S256).

Next, the power consumption management apparatus 101 transmits a response signal including response information to the consumer device 202 that is the transmission source via the Internet 10 (step S258).

Next, when the consumer device 202 receives the response signal including the response information from the power consumption management device 101, the consumer device 202 uses the deletion target load ID indicated by the deletion target load information that is temporarily stored, and deletes the corresponding deletion target. The control I/F and control method corresponding to the load ID are deleted from the load control table Tbl2 in the storage unit 45 (step S260).

As described above, in the consumer device according to the second embodiment of the present invention, the transmission unit 43 transmits the new load information regarding the new load 205, which is the load 205 to be newly registered in the power demanding facility. .. The receiving unit 42 receives the response information indicating that the new load 205 has been registered.

With such a configuration, the new load 205 can be registered in the device on the aggregator side, for example, by the process in the consumer device 202, so that the operator's burden of operating the device on the aggregator side and registering the new load 205 is reduced.

<Third Embodiment>
The present embodiment relates to a power consumption management system that performs control based on a load state as compared with the power consumption management system according to the first embodiment. The power consumption management system according to the first embodiment is the same as the power consumption management system according to the first embodiment except for the contents described below.

FIG. 20: is a figure which shows the structure of the customer apparatus in the power consumption management system which concerns on the 3rd Embodiment of this invention.

Referring to FIG. 20, consumer device 202 further includes a state information acquisition unit 50 and a deletion unit 51, as compared with the consumer device according to the first embodiment of the present invention.

FIG. 21: is a figure which shows the structure of the power consumption management apparatus in the power consumption management system which concerns on the 3rd Embodiment of this invention.

Referring to FIG. 21, power consumption management device 101 further includes a deletion unit 30 and an evaluation unit 31 as compared with the power consumption management device according to the first embodiment of the present invention.

[Getting control status]
Referring again to FIG. 20, the state information acquisition unit 50 in the consumer device 202 acquires the state information indicating the operation state of the target load 205, for example, periodically.

Specifically, the state information acquisition unit 50 acquires, for example, the state of the switch of the target load 205 that receives the contact signal control by the control unit 44 as the operating state. The status information acquisition unit 50 may directly acquire the status of the switch from the target load 205, or may receive the control result of the contact signal control from the control unit 44.

Further, the state information acquisition unit 50 acquires, for example, the state and the set value of the switch of the target load 205 that is subjected to network control by the control unit 44 as the operating state. The status information acquisition unit 50 may acquire the status of the switch and the setting value from the target load 205 via the LAN 11, or may acquire the control result of network control from the control unit 44.

The status information acquisition unit 50 generates status information including the status and setting value of the switch of the target load 205 and the corresponding target load ID (hereinafter, also referred to as evaluation target load ID), and the generated status information and its own. The address of the consumer device 202 and the address of the power consumption management device 101 are output to the transmission unit 43.

For example, when the transmission unit 43 receives the state information, the address of the consumer device 202 and the address of the power consumption management device 101 from the state information acquisition unit 50, the state information and the consumer are addressed to the address of the power consumption management device 101. A status signal including the address of the device 202 is transmitted to the power consumption management device 101 via the Internet 10.

[Evaluation of control status]
Referring to FIG. 21 again, when receiving unit 22 in power consumption management device 101 receives a status signal from consumer device 202 via Internet 10, it outputs the received status signal to evaluation unit 31.

When the evaluation unit 31 receives the status signal from the reception unit 22, the evaluation unit 31 acquires the status information and the address of the consumer device 202 of the transmission source from the received status signal. The evaluation unit 31 acquires the state and set value of the switch of the target load 205 and the evaluation target load ID from the state information.

The evaluation unit 31 evaluates the control of the consumer device 202 with respect to the target load 205 based on the acquired state information.

Specifically, for example, the evaluation unit 31 acquires the control content given by the load determination unit 25 for the target load 205 corresponding to the evaluation target load ID from the load determination unit 25, and acquires the acquired control content and target load. The control of the consumer device 202 with respect to the target load 205 is evaluated by comparing the state of the switch of 205 and the set value.

For example, the evaluation unit 31 uses the state information before the DR start timing and the state information after the DR start timing as a reference when performing the above comparison.

For example, the evaluation unit 31 evaluates the control of the consumer device 202 for the target load 205 as “good” when the control content matches the switch state and the set value of the target load 205.

On the other hand, for example, when the control content does not match the switch state and the set value of the target load 205, the evaluation unit 31 evaluates the control of the consumer device 202 for the target load 205 as “defective”.

For example, when the control of the consumer device 202 for the target load 205 is evaluated as “defective”, the evaluation unit 31 notifies the load determination unit 25 of the evaluation result, and also evaluates the target load ID and the consumer device of the transmission source. The address of 202 is output to the deletion unit 30.

Note that the evaluation unit 31 notifies the load determination unit 25 of the evaluation result when the control of the consumer device 202 with respect to the target load 205 is evaluated as “defective” multiple times, and also the evaluation target load ID and the transmission result. The address of the original consumer device 202 may be output to the deletion unit 30.

Determine one or more target power saving patterns to be targeted.

The load determination unit 25 generates target load control information based on the determined target power saving pattern, and transmits the generated target load control information to the consumer device 202 via the transmission unit 23.

[Delete Target Load 205 with Poor Evaluation]
The deletion unit 30 determines the target load 205 to be deleted from the candidates of the target load 205 stored in the storage unit 26 based on the evaluation result of the control by the evaluation unit 31, and stores information on the determined target load 205. Delete from section 26.

Specifically, for example, when the deletion unit 30 receives the evaluation target load ID and the address of the consumer device 202 of the transmission source from the evaluation unit 31, the target load 205 corresponding to the evaluation target load ID should be deleted. It is recognized as 205.

Then, the deletion unit 30 deletes the controllable amount and control content corresponding to the evaluation target load ID in the DLC mapping table Tbl1 in the storage unit 26, for example.

Then, the deletion unit 30 outputs, to the transmission unit 23, response information indicating that the registration of the target load 205 corresponding to the evaluation target load ID has been deleted, and the address of the consumer device 202 that is the transmission source.

For example, when the transmission unit 23 receives the response information and the address of the transmission source consumer device 202 from the deletion unit 30, the transmission unit 23 addresses the received address as a destination and transmits a response signal including the response information to the transmission source consumer device of the state information. It transmits to 202 via the internet 10.

Referring again to FIG. 20, when the reception unit 42 in the consumer device 202 receives a response signal from the power consumption management device 101 via the Internet 10, the reception unit 42 acquires response information from the received response signal and acquires the response. The information is output to the deletion unit 51.

Upon receiving the response information from the receiving unit 42, the deleting unit 51 recognizes that the registration of the target load 205 corresponding to the evaluation target load ID has been deleted based on the received response information. Then, the deletion unit 51 deletes the control I/F and the control method corresponding to the evaluation target load ID from the load control table Tbl2 in the storage unit 45.

When the deletion unit 30 receives the evaluation target load ID from the evaluation unit 31, the deletion unit 30 deletes the controllable amount and control content corresponding to the received evaluation target load ID from the DLC mapping table Tbl1. It is not limited to.

For example, when the deleting unit 30 can communicate with the target load 205 corresponding to the evaluation target load ID using the ECONET protocol, the deleting unit 30 acquires the operation state of the target load 205 and acquires the acquired operation state. May be configured to be self-checked and then the corresponding information is deleted from the DLC mapping table Tbl1 based on the check result.

[Operation when evaluating control status]

Then, the power consumption management apparatus 101 evaluates the control of the consumer device 202 with respect to the target load 205 based on the acquired state information (step S334).

For example, when the evaluation result of the target load 205B is “defective”, the power consumption management apparatus 101 saves power in the power saving patterns included in the DLC mapping table Tbl1 excluding the target power saving pattern that is currently the target of power saving. From the patterns, the power saving pattern corresponding to the target load 205D is determined as a new target power saving pattern (step S336).

Next, the power consumption management apparatus 101 generates target load control information including the target load candidate ID included in the determined target power saving pattern and the corresponding control content, and the DLC signal including the generated target load control information is consumed by the consumer. The data is transmitted to the device 202 (step S338).

Next, when the consumer device 202 receives the DLC signal from the power consumption management device 101, the consumer device 202 acquires the target load control information from the received DLC signal, and based on the acquired target load control information and the content of the load control table Tbl2. Then, the connection I/F and the control method corresponding to the target load ID are acquired (step S340).

[Getting power consumption]
Referring again to FIG. 24, the consumption information acquisition unit 52 in the consumer device 202 acquires power consumption information indicating the power consumption in the power demanding facility, for example, periodically. Specifically, the consumption information acquisition unit 52 regularly receives the power consumption amount from the power meter 206. The consumption information acquisition unit 52 generates power consumption information including the received power consumption amount, and outputs the generated power consumption information, the address of its own customer device 202 and the address of the power consumption management device 101 to the transmission unit 43. ..

For example, when the transmission unit 43 receives the power consumption information, the address of the consumer device 202 and the address of the power consumption management device 101 from the consumption information acquisition unit 52, the power consumption information and the address of the power consumption management device 101 are set as the destination. A power consumption signal including the address of the consumer device 202 is transmitted to the power consumption management device 101 via the Internet 10.

Referring again to FIG. 25, when the reception unit 22 in the power consumption management device 101 receives the power consumption signal from the consumer device 202 via the Internet 10, the received power consumption signal is sent to the load determination unit 25 and the evaluation unit 32. Output.

Upon receiving the power consumption signal from the reception unit 22, the load determination unit 25 acquires the power consumption information and the address of the consumer device 202 of the transmission source from the received power consumption signal.

The load determination unit 25 calculates, for example, the actual value of the past suppression amount described in the first embodiment of the present invention based on the power consumption amount in the power demanding facility indicated by the acquired power consumption information.

In addition, the load determination unit 25 calculates, for example, a power consumption target which is a target of power consumption indicated by the power management information.

There is. The assumed value of power consumption is, for example, the power consumption when the power consumption is not suppressed, and is calculated based on past power consumption data and the like.

The load determining unit 25 calculates, for example, a value obtained by subtracting the average sum calculated by the above method (A1) from the assumed value of the power consumption as the power consumption target. The load determination unit 25 outputs the calculated power consumption target to the evaluation unit 32.

The load determining unit 25 may calculate, for example, a value obtained by subtracting the estimated suppression amount K from the estimated power amount M calculated by the method (B) described above as the power consumption target.

The evaluation unit 32 compares the power consumption amount indicated by the power consumption information received by the reception unit 22 with the power consumption target indicated by the power management information, and based on the comparison result, the consumer device 202 for the target load 205.

Specifically, when the evaluation unit 32 receives the power consumption signal from the reception unit 22, the evaluation unit 32 acquires the power consumption information from the received power consumption signal.

The evaluation unit 32 compares the power consumption amount indicated by the acquired power consumption information with the power consumption target received from the load determination unit 25.

For example, when the power consumption is less than or equal to the power consumption target, the evaluation unit 32 evaluates the control of the consumer device 202 with respect to the target load 205 as “good”.

On the other hand, for example, when the power consumption exceeds the power consumption target, the evaluation unit 32 evaluates the control of the consumer device 202 with respect to the target load 205 as “defective”.

For example, when the evaluation unit 31 evaluates the control of the consumer device 202 for the target load 205 as “defective”, the evaluation unit 31 outputs a control failure notification to the load determination unit 25.

The evaluation unit 31 may output the control failure notification to the load determination unit 25 when the control of the consumer device 202 with respect to the target load 205 is evaluated as “defective” multiple times.

[Addition of target load 205]
Further, when the load determination unit 25 receives the control failure notification from the evaluation unit 31, the load determination unit 25 performs the following processing. That is, for example, the load determination unit 25 newly selects a power saving pattern from the power saving patterns included in the DLC mapping table Tbl1 illustrated in FIG. 4 excluding the current power saving target power saving pattern. One or more target power saving patterns to be determined are determined.

The load determination unit 25 generates target load control information based on the determined target power saving pattern, and transmits the generated target load control information to the consumer device 202 via the transmission unit 23.
