Description

  The present invention relates to a technology that balances the amount of power supplied, including power generated by solar power generation, etc., in which the amount of power generation changes due to weather changes and the like, and the amount of power demanded by the power supply destination.

  Power supply (power generation) is controlled so that the supply amount (supply power amount) is equal to the demand amount (demand power amount) requested by the supply destination. However, due to the increasing tendency of power plants that use natural energy (renewable energy) such as sunlight and wind power, it is difficult to balance the amount of supplied power and the amount of demand power.

  That is, the amount of power generated by renewable energy increases due to an increase in power plants that use renewable energy, and the proportion of the amount of power generated by renewable energy in the amount of supplied power is increasing. The amount of electric power generated by renewable energy tends to fluctuate due to weather changes and is difficult to control. For this reason, it has become difficult to control the amount of power supplied including renewable energy. Under such circumstances, there may occur a situation in which the amount of supplied power becomes larger than the amount of demanded power. In this case, excessive supplied power is discarded, for example, and is wasted.

  Therefore, in order to eliminate such waste, a method of storing a power supply amount that is excessive in comparison with the power demand amount in a storage battery is conceivable. However, there is a problem that such a storage battery is expensive. Further, in Patent Document 1, in order to balance energy demand and supply, energy consumption is recommended to consumers in a time zone where energy supply is likely to exceed demand, and time when demand is likely to exceed supply. In the band, a technology that recommends consumers to reduce energy consumption is shown.

  Patent Document 2 discloses a technique for suppressing fluctuations in the power supply frequency that the power fluctuations of the distributed power supply such as renewable energy give to the power system. Patent Document 3 discloses a technique for managing surplus power related to a power retail business.

  Embodiments according to the present invention will be described below with reference to the drawings.

<First Embodiment>
FIG. 1 is a block diagram showing a simplified configuration of a receipt adjustment apparatus according to the first embodiment of the present invention. The receipt adjustment apparatus 1 of 1st Embodiment is integrated in the receipt adjustment system 5 as represented in FIG. The receipt adjustment system 5 increases the power consumption by promoting power consumption when the amount of power supplied by the power source is assumed to be excessive (in other words, surplus power is generated). It is a system to suppress.

  The receipt adjustment system 5 includes a receipt adjustment device 1 and a device management device 6. The device management apparatus 6 has a function of performing operation control related to an increase in power consumption of the electrical device 8 connected to the electrical device 8 that is a receipt adjustment candidate. The receipt adjustment candidate electrical device 8 is an electrical device selected in advance as an electrical device that suppresses surplus power by increasing power consumption when surplus power is assumed to be generated. As the electrical device 8 that is a receipt adjustment candidate, for example, an electrical device that is unlikely to have an adverse effect such as a change in driving conditions caused by an increase in power consumption causes distrust to the user is selected.

  The receipt adjustment device 1 is configured by a control device including, for example, a CPU (Central Processing Unit), and includes a collection unit 2, a grouping unit 3, and an allocation unit 4 as functional units as illustrated in FIG. .

  The collection unit 2 has a function of collecting dynamic information related to the operation status of the electrical device 8. The dynamic information related to the operation status is information on an event that affects the operation status of the electric device 8 and can change. For example, when the electric device 8 is an electric device provided with a heat pump, one of the dynamic information is an ambient environmental temperature that affects the operation status of the heat pump. The collection unit 2 may collect one type of dynamic information designated in advance for each electric device 8 or may collect a plurality of types of dynamic information.

  The grouping unit 3 has a function of dividing the plurality of electrical devices 8 into a plurality of groups based on the dynamic information collected by the collection unit 2. For example, when multiple types of dynamic information are collected for each electrical device 8 by the collection unit 2, the grouping unit 3 groups the electrical devices 8 having the same combination of values of the multiple types of dynamic information into the same group. Classify into:

  In addition, the method of grouping the plurality of electric devices 8 based on the dynamic information may be determined in advance, and an appropriate method is adopted. In addition, the grouping of the electric devices 8 by the grouping unit 3 is reviewed at each preset timing, for example. The timing of the review is not limited as long as it is determined in advance, and may be, for example, every set time interval or may be a time when a predetermined review condition is satisfied.

  The allocating unit 4 has a function of allocating, as a consumption promotion amount, to all groups by the grouping unit 3 or to a specified part of the group to consume the estimated surplus power amount.

  Various methods can be considered as a method for allocating the estimated surplus power. For example, the allocating unit 4 calculates the increase in the amount of power that can be consumed in each group based on the dynamic information used by the grouping unit 3 for grouping, and sets the consumption promotion amount in the order of the calculated large increase group. Assign. Alternatively, when the amount of power obtained by equally dividing the estimated surplus power amount is assigned to each group by the grouping unit 3 as the consumption promotion amount, the consumption promotion amount assigned to each group represents the increase in the amount of power that can be consumed in each group. It will not exceed. In this case, the assigning unit 4 may assign the estimated surplus power amount equally to each group. Based on an allocation method appropriately selected from such various allocation methods, the allocation unit 4 allocates the estimated surplus power amount to the group by the grouping unit 3. For example, the allocation unit 4 allocates the estimated surplus power amount to the group after review each time the grouping unit 3 reviews the group of the electrical devices 8.

  The device management apparatus 6 controls the operation of the electric device 8 in consideration of the consumption promotion amount for each group determined by the assignment unit 4.

  As described above, the receiving adjustment device 1 of the first embodiment groups the plurality of electric appliances 8 as receiving adjustment candidates based on the dynamic information related to the operation status of the electric appliance 8, and based on the dynamic information. The estimated surplus power amount is allocated to each group as a consumption promotion amount. Since the grouping is based on dynamic information related to the driving situation, the group takes into account changes in the driving situation, and appropriate power consumption according to the driving situation is promoted to the group. Assigned as a quantity. For this reason, the group (electrical equipment 8) can consume the allocated consumption promotion amount favorably. That is, the receipt adjustment system 5 including the receipt adjustment device 1 can allocate an appropriate surplus power amount to a group that can consume the estimated surplus power amount in accordance with the driving situation, and thus increase the amount of power consumption favorably. It is possible to appropriately adjust the balance between the power supply amount and the power demand amount. In addition, since the receipt adjustment system 5 assigns the consumption promotion amount in units of groups, the consumption promotion amount can be more reliably consumed than when the consumption promotion amount is assigned to each electrical device 8.

Second Embodiment
The second embodiment according to the present invention will be described below.

  FIG. 3 is a block diagram schematically illustrating the configuration of the receipt adjustment system according to the second embodiment of the present invention together with the system on the supply side. The supply-side system to which the receipt adjustment system 15 of the second embodiment is connected includes a renewable energy power plant 20, a power plant 21, an output control device 22, and an aggregation device 23.

  The renewable energy power plant 20 is a facility that generates power using renewable energy (natural energy such as sunlight and wind). Each renewable energy power plant 20 includes a control device 24 that can communicate with the aggregation device 23. The control device 24 has a function of generating power generation history information in which power generation amount and information related to power generation such as the time of power generation are associated, and transmitting the power generation history information to the aggregation device 23.

  The power plant 21 is a power plant belonging to a company (electric power company) 25 that conducts a business of supplying power. The power plant 21 belonging to the electric power company 25 is not limited to one and may include a plurality of power plants. Here, these power plants are collectively referred to as the power plant 21. The power plant 21 belonging to the electric power company 25 includes a power plant that generates power using fossil fuel and a power plant that uses a pump.

  The output control device 22 includes, for example, a CPU (Central Processing Unit) (not shown) and a storage unit (not shown), and has a function of creating a power generation plan (power generation schedule) at the power plant 21. I have. For example, the output control device 22 is communicable with the aggregation device 23, and from the aggregation device 23, the renewable energy power generation that is the total predicted power generation amount of all the renewable energy power plants 20 in the preset prediction period Th. Receive the predicted amount. In addition, the output control device 22 uses the consumption history information stored in advance (for example, past power consumption actual value or a calculated value obtained by statistically processing the actual value) to predict power in the prediction period Th. The demand amount (consumption amount) to be calculated is calculated as a demand forecast amount. Then, the output control device 22 calculates a power generation amount that requires power generation in the power plant 21 in the prediction period Th based on the predicted renewable energy generation amount and the demand prediction amount, and the power plant based on the calculated power generation amount. Create 21 power generation plans (power generation schedules). Here, the power generation plan is a power generation plan that represents the relationship between the date and time and the power generation amount (power generation plan amount) that the power plant 21 should generate, and the output control device 22 uses the power generation plan based on the power generation plan. The power generation operation of the power plant 21 is controlled so as to generate the amount.

  Incidentally, the power plant 21 has a control range in which the amount of power generation can be variably controlled due to the equipment. For this reason, there is a case where there is a case where the amount of power generation at the power plant 21 cannot be reduced even if it is attempted to reduce the amount of power generation at the power plant 21 to meet the demand forecast amount because the amount of predicted renewable power generation is large. Yes. In this case, the output control device 22 calculates the amount of power obtained by subtracting the demand prediction amount from the total value of the power generation prediction amount and the renewable energy generation prediction amount at the power plant 21 in the prediction period Th as the estimated surplus power amount. The function of outputting the information of the estimated surplus power amount to the aggregation device 23 is provided. The method for calculating the estimated surplus power amount is not limited to the method using the demand forecast amount as described above. For example, a calculated value obtained by subtracting a value obtained by summing the output upper limit values at a predetermined renewable energy power plant 20 from a predicted amount of renewable energy generation that is the total power generation amount of the renewable energy power plant 20 that is the target of the output upper limit value. A calculation method that uses the estimated surplus power may be employed. The output upper limit value is a value obtained by multiplying the rated output value of the renewable energy power plant 20 by the set ratio.

  The aggregation device 23 has a function of outputting information on the estimated surplus power received from the output control device 22 toward the receipt adjustment system 15. That is, the aggregation device 23 is connected to the receipt adjustment system 15. When the aggregation device 23 receives information on the estimated surplus power amount from the output control device 22, the aggregation device 23 transmits information on the estimated surplus power amount to the reception adjustment system 15 in order to reduce the surplus power amount.

  In addition, the aggregation device 23 includes, for example, a CPU (Central Processing Unit) (not shown) and a storage unit (not shown), and collects the electric power generated at each renewable energy power plant 20. It has a function to manage. For example, the aggregation device 23 is communicably connected to the control device 24 of the renewable energy power plant 20, and the power generation history information transmitted from the control device 24 (for example, the past power generation result value or the actual result) (A calculated value obtained by statistically processing the value). Further, the aggregation device 23 uses the generated power generation history information to calculate the predicted total power generation amount of all the renewable energy power plants 20 in the preset prediction period Th as the renewable energy generation predicted amount. It has a function. Furthermore, the aggregation device 23 has a function of transmitting the calculated renewable energy generation predicted amount to the output control device 22.

  Furthermore, the aggregation device 23 makes a power generation plan (power generation schedule) for each renewable energy power plant 20 using the power generation history information and the like, holds the power generation plan, and controls each power plant 20. The power generation plan is output to 24. The control device 24 controls the output of the renewable energy power plant 20 based on the received power generation plan.

Furthermore, the aggregation device 23 may receive information on the amount of power that cannot be adjusted from the receipt adjustment system 15. That is, although a plan for increasing the power consumption in the receipt adjustment system 15 is made, it is expected that the increase in power does not reach the estimated surplus power and surplus power may be generated in the plan. There is a case. In this case, information on the amount of power that could not be adjusted by the receiving adjustment system 15 is output from the receiving adjustment system 15 to the aggregation device 23 as information on the amount of power that cannot be adjusted. In such a case, the aggregation device 23 generates power at the renewable energy power plant 20 to suppress power generation (output) of the amount of power corresponding to the amount of power that cannot be adjusted based on the received information about the amount of power that cannot be adjusted. It has a function to review the plan (output plan) and update the power generation plan. For example, the power amount that cannot be adjusted is calculated according to the following equation (1). The aggregation device 23 uses the calculated non-adjustable power amount (that is, surplus power amount) Psur as the review amount, and the power generation plan (output) in the renewable energy power plant 20 so that the power generation (output) of the review amount can be reduced. Review the plan.
Psur = ( _P21dw + _P20ge )-(Pden + Ppro) (1)
Psur in equation (1) represents an unadjustable power amount (review amount). P _21dw represents the power generation amount when the power generation amount at the power plant 21 is lowered to the lower limit value of the control range. P _20ge represents a predicted amount of _renewable energy generation at the _renewable energy power plant 20. Pden represents a demand forecast amount. Ppro represents the amount of power that can be increased (promoted) in power consumption planned by the receipt adjustment system 15.

  When reviewing the power generation plan, for example, the aggregation device 23 may select the number of renewable energy power plants 20 corresponding to the amount of power generation to be suppressed and review the power generation plan of the selected renewable energy power plants 20. The power generation plans of all renewable energy power plants 20 may be reviewed.

  As described above, the receipt adjustment system 15 has a function of reducing waste of surplus power by promoting power consumption in response to a request from the aggregation device 23 (output control device 22). As shown in FIG. 3, the receipt adjustment system 15 includes a receipt adjustment device 16 and a device management device 17. The aggregation device 23 and the receipt adjustment device 16 are provided in a mechanism having a power mediation control function for transmitting the electric power generated at the renewable energy power plant 20 to the electric device 18.

  The device management apparatus 17 is connected to a plurality of electrical devices 18 that are candidates for receipt adjustment via, for example, an information communication network, and has a function of controlling the operation of the electrical device 18. The device management apparatus 17 is installed in a company that manages a plurality of electrical devices 18, for example. In the second embodiment, the electrical device 18 is a vending machine that sells beverages, for example, and includes a heat pump and a compressor.

  The device management apparatus 17 holds various information including information indicating the state of each electric device 18 and information necessary for management. The information representing the state of the electrical device 18 includes, for example, information such as the type of product being sold, its inventory status, sales amount, sales trend, product replenishment time, and next replenishment scheduled time.

  The device management device 17 has a function of returning information requested from the receipt adjustment device 16 to the receipt adjustment device 16. Moreover, when the information of the consumption plan (consumption schedule) is received from the receipt adjustment device 16, the device management device 17 controls the operation of each electrical device 18 based on the consumption plan.

  The receipt adjustment device 16 includes a collection unit 30, a grouping unit 31, and an allocation unit 32 as illustrated in FIG. The collection unit 30, the grouping unit 31, and the allocation unit 32 are realized by a control device 26 including, for example, a CPU (Central Processing Unit) and a memory. That is, the receipt adjustment device 16 includes a storage device 27, and the storage device 27 stores a computer program that implements the collection unit 30, the grouping unit 31, and the allocation unit 32. The CPU of the control device 26 has functions of a collection unit 30, a grouping unit 31, and an allocation unit 32 by executing a computer program of the storage device 27 using a memory.

  The collection unit 30 has a function of collecting dynamic information related to the operation status of the electrical device 18. The dynamic information is information on an event that affects and changes the operating status of the electrical device 18 (in particular, the operating status of the heat pump in the second embodiment). The dynamic information includes, for example, information on the type and stock status of the product in the electrical device 18 (vending machine), the elapsed time of product replenishment, and the environmental status around the electrical device 18. That is, when the product is stored in the electrical device 18 in a refrigerated state, if the product at room temperature is replenished to the electrical device 18, the operation amount of the heat pump of the electrical device 18 is increased in order to cool the supplemented product. Is done. In addition, even when the temperature around the electric device 18 is high or the amount of solar radiation is large, it is assumed that the operation amount of the heat pump is increased in order to maintain the refrigerated state of the product. Further, when the product is a new product or a popular product, the scheduled replenishment amount and the replenishment frequency of the electrical device 18 increase, so that the heat pump of the electrical device 18 is cooled as described above in order to cool the supplemented product. It is assumed that the amount of operation is increased. As described above, the product type, inventory status, replenishment time information, ambient environmental temperature, amount of solar radiation, and the like are related to the operating status of the electrical device 18.

  The collection unit 30 provides dynamic information from the device management device 17 on information such as the type, stock status, and replenishment elapsed time of products stored in each electrical device 18 (vending machine) held by the device management device 17. Collect as. The collection unit 30 may collect sales information from the device management apparatus 17 instead of the inventory status of the product. Furthermore, the collection unit 30 may also collect information on sales trends of products calculated by the device management device 17 in each electrical device 18 from the device management device 17. Further, the collection unit 30 may collect the above-described product type, stock status, replenishment elapsed time, sales information, sales trend information, and the like directly from each electrical device 18 instead of the device management device 17. .

  The information on the environmental condition around the electrical device 18 includes, for example, information such as the environmental temperature, the amount of sunlight, and the air volume. In order to collect such information, when a measuring device (sensor) that measures weather-related information such as temperature, amount of sunshine, and air volume is installed around the electrical device 18, the collecting unit 30 Weather-related information directly from various measuring devices. Alternatively, the collection unit 30 is connected to an information providing source (for example, a company providing weather-related information) 33 represented by a dotted line in FIG. Information on the surrounding environmental conditions may be collected as dynamic information. Further, when the device management apparatus 17 acquires and holds information on the environmental conditions around each electric device 18, the collection unit 30 receives information on the environmental conditions around each electric device 18 from the device management apparatus 17. May be collected.

  In the second embodiment, the collection unit 30 collects the dynamic information as described above at a predetermined collection timing. Examples of the collection timing include a set time interval, a time when information on the estimated surplus power amount is received from the aggregation device 23, a time when a predetermined collection condition is satisfied, and the like.

  For example, when dynamic information is collected by the collection unit 30, the grouping unit 31 has a function of dividing the plurality of electrical appliances 18 as receiving adjustment candidates into a plurality of groups based on the collected dynamic information. For example, the receiving adjustment device 16 not only includes dynamic information on the electrical adjustment device 18 that is a candidate for receiving adjustment, but also information on the rated power consumption of the device and information indicating the installation location (indoors, outdoors, etc.) (hereinafter, such dynamics). Unintentional information is also referred to as fixed information). Based on such fixed information and the dynamic information collected by the collection unit 30, the grouping unit 31 groups the plurality of electrical devices 18 so that the electrical devices 18 in the same state are in the same group. .

  For example, FIG. 5 shows an example of items and conditions when a plurality of electrical devices 18 are roughly divided into two groups A and B. In the example of FIG. 5, as information (items) used for grouping, the rated power consumption of the vending machine, the installation location, the amount of solar radiation per unit time, the ambient temperature of the electrical equipment 18, the inventory status of the product, and the replenishment schedule Information on the amount and elapsed time of replenishment of goods is listed. The grouping unit 31 roughly divides the plurality of electric devices 18 into two groups A and B based on such information. Note that a threshold is set in advance for determining whether the information (items) such as the amount of solar radiation and inventory used for grouping is large or small (some). In addition, subgroups may be defined for groups A and B.

  The number of groups grouped by the grouping unit 31 is not limited to two and may be three or more. Further, the number of groups is not a fixed value, and may be changed according to changes in dynamic information such as temperature. In the case of changing the number of groups, for example, the relationship data between the temperature and the number of groups in the dynamic information is given to the receipt adjustment device 16. The grouping unit 31 determines the number of groups into which the electric devices 18 are grouped based on the relationship data and the dynamic information. Further, information (grouping item information) of items used for grouping and their conditions is given according to the number of groups, and the grouping unit 31 is based on the grouping item information according to the number of groups. The electric devices 18 are grouped.

  After the grouping, the grouping unit 31 generates information that associates the group with the electrical device 18 classified into the group, and stores the information in the storage device 27, for example.

  Note that the timing at which the grouping unit 31 executes grouping may not coincide with the timing at which the collection unit 30 collects dynamic information. For example, grouping may be executed when, for example, the temperature of the dynamic information collected by the collection unit 30 fluctuates by a predetermined fluctuation rate or more.

  The allocating unit 32 determines the estimated surplus power output from the aggregation device 23 on the power source (supply) side to the reception adjusting device 16 for all groups in which the electrical devices 18 are classified by the grouping unit 31 or one specified A function of allocating as a consumption promotion amount to a group of departments is provided. For example, in each group in which the electrical device 18 is classified by the grouping unit 31, the power allocation order and the allocation amount are set. The allocating unit 32 allocates the estimated surplus power amount as the consumption promotion amount by the set allocation amount in order from the higher rank group. Various methods are conceivable as a method of assigning the estimated surplus power amount as the consumption promotion amount to the group in which the electrical devices 18 are classified. Among these methods, an appropriate method selected in consideration of the size of the estimated surplus power amount, the type and capability of the electric appliance 18 to be received and adjusted, and the like may be adopted as the allocation method. For example, the allocation unit 32 may allocate the consumption promotion amount according to the power amount that can be consumed in order from the group with the largest power amount that can be consumed, instead of allocating the consumption promotion amount equally to each group.

  Furthermore, the allocating unit 32 has a function of making a power consumption plan (consumption schedule) in the electrical equipment 18 of each group in consideration of the consumption promotion amount allocated to each group. For example, a basic pattern of a power consumption plan (relationship data between time zone and power consumption) of each electric device 18 is given in advance, and the allocation unit 32 changes the basic pattern in consideration of the consumption promotion amount. To make a consumption plan.

  Furthermore, the assigning unit 32 has a function of outputting information on a consumption plan (consumption schedule) to the device management apparatus 17. As described above, when receiving the consumption plan, the device management apparatus 17 controls the operation of the electrical device 18 based on the consumption plan.

  Furthermore, even if the allocation unit 32 allocates the estimated surplus power amount to the group in which the electrical device 18 is classified, the estimated surplus power amount may remain. That is, there is a limit to the allowable amount that can increase the amount of power consumed by the electrical device 18 depending on the usage status of the electrical device 18 and the surrounding environment. For this reason, there is a limit to the amount of consumption promotion that can be assigned to the group of electrical devices 18. As a result, for example, when the estimated surplus power output from the aggregation device 23 is large due to the large amount of power generated at the renewable energy power plant 20, all of the surplus estimated power cannot be allocated to the group. Occur. In other words, although an attempt has been made to increase power consumption in order to reduce the estimated surplus power amount, it is expected that surplus power will be generated without the increase in consumption reaching the estimated surplus power amount. In such a case, the allocating unit 32 outputs information on the amount of power that could not be allocated (in other words, the amount of power that could not be adjusted) to the aggregation device 23 as information on the amount of power that could not be adjusted. It has. As described above, when the aggregation device 23 receives the information, the aggregation device 23 reviews the power generation plan in the renewable energy power plant 20 in order to suppress the power generation amount in the renewable energy power plant 20.

  Below, the operation example of the receipt adjustment apparatus 16 in 2nd Embodiment is demonstrated using the sequence diagram of FIG.

  For example, when the output control device 22 makes a power generation plan at the power plant 21 in consideration of the information on the predicted power generation amount at the renewable energy power plant 20 and the predicted power consumption at the power supply destination, It is assumed that the amount of power is greater than the amount of demand power and surplus power is generated. In this case, the output control device 22 outputs information on the estimated surplus power amount to the receipt adjustment device 16 via the aggregation device 23 (step S101).

  Upon receipt of the information on the estimated surplus power amount, the collection unit 30 of the receipt adjustment device 16 collects dynamic information related to the operating status of each electrical device 18 that is a receipt adjustment candidate from, for example, the appliance management device 17 (step S102). . Note that the collection unit 30 may collect dynamic information from the electrical device 18.

  Then, the grouping unit 31 groups the plurality of electrical devices 18 that are candidates for receipt adjustment based on the dynamic information related to each electrical device 18 (step S103).

  Thereafter, the assigning unit 32 assigns the estimated surplus power amount as a consumption promotion amount to all the groups in which the electrical devices 18 are classified by the grouping unit 31 or to some groups specified from all the groups (step S104). ). Then, the allocating unit 32 determines whether or not a part of the estimated surplus power amount could not be allocated (there is surplus) after the allocation of the estimated surplus power amount (step S105).

  When there is a surplus, the allocating unit 32 transmits information on the surplus of the estimated surplus power amount that could not be allocated to the aggregation device 23 as information on the unadjustable power amount (step S106). In addition, the allocating unit 32 sets (updates) a consumption plan for the electrical devices 18 belonging to the group so that the power consumption in the group to which the consumption promotion amount is allocated increases by the consumption promotion amount ( Step S107).

  On the other hand, all of the estimated surplus power can be allocated to the group, and if there is no surplus, the allocating unit 32 does not need to transmit the information on the unadjustable power to the aggregation device 23, and the consumption in step S107. Perform planning actions.

  Then, the allocating unit 32 transmits the updated consumption plan for each electrical device 18 to the device management apparatus 17. Upon receiving the updated consumption plan, the device management apparatus 17 controls the operation of each electrical device 18 in consideration of the consumption plan.

  In addition, the aggregation device 23 that has received the information on the unadjustable power amount reviews the power generation plan in the renewable energy power plant 20 to suppress the power generation corresponding to the unadjustable power amount, and suppresses the power generation amount (step S108).

  As in the first embodiment, the receipt adjustment system 15 including the receipt adjustment device 16 of the second embodiment groups a plurality of electrical appliances 18 that are candidates for receipt adjustment based on dynamic information related to the operating status of the electrical appliances 18. The estimated surplus power amount is allocated as a consumption promotion amount to the group based on the dynamic information. For this reason, the receipt adjustment system 15 can acquire the effect similar to 1st Embodiment. That is, the receipt adjustment system 15 can adjust the power consumption satisfactorily in order to balance the supply power amount and the demand power amount, and can appropriately adjust the balance between the supply power amount and the demand power amount. Moreover, since the receipt adjustment system 15 allocates a consumption promotion amount per group, compared with the case where a consumption promotion amount is allocated to each electric equipment 18, consumption of the consumption promotion amount can be made more reliable.

  Furthermore, in the case of allocating the consumption promotion amount according to the power amount that can be consumed in the order of the group with the largest amount of power that can be consumed, the allocation unit 32 is compared with the case of allocating the consumption promotion amount equally to each group. Therefore, it is possible to assign a consumption promotion amount suitable for the power consumption capacity to the group.

  Furthermore, instead of grouping the electrical devices 18 every time the collection unit 30 collects dynamic information, the grouping is performed when the electrical devices 18 are grouped when the variation rate of the dynamic information exceeds a threshold. The part 31 can suppress the situation where grouping is performed unnecessarily frequently.

  Furthermore, in the second embodiment, the electrical device 18 is a vending machine, and the receipt adjustment device 16 collects the type of goods, the stock status, the replenishment elapsed time, etc. of the vending machine as dynamic information. The vending machines are grouped based on the collected information. Information on the type of product, inventory status, and elapsed time of replenishment of the product is information related to power consumption unique to vending machines, so surplus power can be obtained by performing grouping related to power consumption based on this information. Vending machines can be grouped appropriately for quantity allocation. That is, when the product is stored in the electrical device 18 in a refrigerated state, if the product at room temperature is replenished to the electrical device 18, the operation amount of the heat pump of the electrical device 18 is increased in order to cool the supplemented product. Is done. For this reason, the types and stock status of products in the electrical device 18 (vending machine) and the replenishment elapsed time of the products are acquired as dynamic information and used for grouping, so that the electrical devices 18 are grouped in descending order of power consumption. be able to. In addition, even when the temperature around the electric device 18 is high or the amount of solar radiation is large, it is assumed that the operation amount of the heat pump is increased in order to maintain the refrigerated state of the product. Therefore, by acquiring environmental information (for example, temperature) around the electric device (vending machine) 18 as dynamic information and using it for grouping, the electric devices 18 can be grouped in descending order of power consumption. Further, when the product is a new product or a popular product, the scheduled replenishment amount and the replenishment frequency of the electrical device 18 increase, so that the heat pump of the electrical device 18 is cooled as described above in order to cool the supplemented product. It is assumed that the amount of operation is increased. For this reason, the electric appliances 18 can be grouped in descending order of power consumption by acquiring the type of product (information on whether it is a new product or a popular product) as dynamic information and using it for grouping.

  In the second embodiment, a vending machine is used as the electric appliance 18 as a receipt adjustment candidate. Since the change in the operating condition of the heat pump in the vending machine is less likely to cause a bad influence on the user in distrust of the operation of the machine, the adoption of the vending machine as the electric appliance 18 that is a receipt adjustment candidate The effect that increase is easy to achieve can be obtained.

<Other embodiments>
In addition, this invention is not limited to 1st and 2nd embodiment, Various embodiment can be taken. For example, in the second embodiment, an example is described in which the electrical device 18 that is a receipt adjustment candidate is a vending machine, but the electrical device 18 that is a receipt adjustment candidate includes another type of electrical device (for example, a heat pump). A water heater). In addition, multiple types of electrical devices may be employed as the receipt adjustment candidate electrical devices.

  Furthermore, the device management apparatus 17 included in the receipt adjustment system 15 in the second embodiment is not limited to one. For example, when a plurality of types of electrical devices are employed as the receipt adjustment candidate electrical devices, as shown in FIG. 7, a plurality of device management apparatuses 17A and 17B corresponding to the types of receipt adjustment candidate electrical devices are used. May be included in the receipt adjustment system 15.

  Furthermore, in the second embodiment, the device management apparatus 17 controls the operation of the electrical device 18 that is a receipt adjustment candidate in order to increase the power consumption. Instead of this, if there is no control device or the like that centrally manages the electrical adjustment candidate appliances, the receipt adjustment device 16 directly increases the power consumption of the electrical adjustment candidate electrical devices. The operation of the electric device 18 may be controlled.

  Furthermore, in the second embodiment, the estimated surplus power amount is calculated by the output control device 22. Instead, the aggregation device 23 or the receiving adjustment device 16 calculates the estimated surplus power amount based on the power generation plan at the power plant 21, the power generation prediction amount at the renewable energy power plant 20, and the power consumption prediction amount. It may be calculated.

  Furthermore, in the operation example of FIG. 6 described in the second embodiment, the collection unit 30 starts collecting dynamic information upon receiving the estimated surplus power amount. Instead of this, for example, the collection unit 30 may collect dynamic information for each preset time interval regardless of reception of the estimated surplus power. And the grouping part 31 groups the electric equipment 18 of a receipt adjustment candidate based on the collected dynamic information. When the estimated surplus power amount is calculated during the operation in which the dynamic information collecting operation and the grouping operation are repeatedly performed at the set time intervals, the allocating unit 32 determines the estimated surplus power amount. One or more groups may be assigned.

  Furthermore, in addition to the configuration of the receipt adjustment device 16 in the second embodiment, the receipt adjustment device 16 has a functional unit that provides services to the electrical equipment 18 that has increased power consumption in order to promote consumption of power. It may be provided. That is, even when the electrical device 18 increases the power consumption so as to promote the power consumption, an electricity fee corresponding to the consumption is charged. In consideration of this, it is possible to consider a service in which the electricity charge related to the consumption of power in response to the demand for increase in consumption is made lower than the normal electricity charge. The receipt adjustment device 16 is provided with a service function that adjusts the electricity rate related to the increase in power consumption in response to a request for an increase in consumption, or is given a service point. Also good.

  Furthermore, in the second embodiment, the aggregation device 23 is represented as a device separate from the receipt adjustment device 16, but one control device has a function as the aggregation device 23 and a function as the receipt adjustment device 16. It may be. Note that the single control device in this case includes a case where a plurality of distributed control devices virtually operate like a single control device.

  Furthermore, in the second embodiment, when the estimated surplus power amount is allocated to the group of the electrical devices 18, but there is an estimated surplus power amount that cannot be allocated (that is, the power amount that cannot be adjusted), the aggregation device 23 The power generation plan of the renewable energy power plant 20 is being reviewed. Instead of this, for example, when there is a power amount that cannot be adjusted, the aggregation device 23 may suppress the output of the renewable energy power plant 20 according to the power amount that cannot be adjusted. That is, the aggregation device 23 performs control to suppress the output of the renewable energy power plant 20 so that the total value of the amount of power suppressed for the renewable energy power plant 20 is the same as the unadjustable power amount.
