Description

  The present invention relates to an energy supply and demand adjustment system.

  In recent years, there has been a discussion of supplying resources related to infrastructure such as electric power, gas, heat, and water that are indispensable for people's lives in a stable and economical manner. There, it is expected that businesses that supply diverse energy and retail under the new system will enter. Energy retailers procure supply from energy markets, etc., and supply energy to consumers through power transmission and distribution networks, gas supply pipes, heat interchange and water. At this time, the energy retailer expects the demand in advance. However, there is a possibility that the actual demand amount exceeds the planned supply amount or the supply amount becomes excessive due to the influence of weather fluctuations or failure of demand equipment.

  As one of countermeasures, there is a method such as demand response that adjusts demand by changing the energy supply price or directly controlling demand (load) equipment.

  In relation to demand adjustment, energy management systems (for homes, buildings, factories, etc.) that implement visualization of energy usage information and remote control of load devices have been introduced to improve energy consumption efficiency. ing. When a retailer adjusts the demand of a consumer, the retailer manages information such as the address and age of the customer targeted for demand adjustment, the time spent using energy, the amount used (load curve), and the like. The retailer performs a request to adjust the demand to the corresponding customer according to the load curve, or directly controls the load device.

  As described above, in the demand adjustment, the retailer may handle information related to the individual of the target customer or may handle the load curve of the target customer. The handling of such personal information by a retailer may lead to grasping the life pattern of a specific individual and may involve privacy issues.

  As a method for preventing infringement of privacy due to leakage of personal information to third parties other than consumers and electric power companies, there is a power usage adjustment device disclosed in Patent Document 1. Patent Document 1 discloses that a power usage adjusting device, system, and program capable of adjusting power usage while protecting the privacy of a consumer are provided.

  In the power usage adjustment device, the receiving unit cannot identify the transmission source of the schedule information indicating the power usage amount for each time zone scheduled by the customer from the plurality of customer devices provided for each customer. Receive in state. The generation unit generates identification information of the schedule information based on the received schedule information. The adjustment unit adjusts at least a part of the schedule information among the plurality of schedule information under the condition that the same adjustment is performed on the schedule information having the same identification information. The broadcast unit broadcasts adjustment information indicating the adjustment result to a plurality of customer devices together with the identification information of the adjusted schedule information.

  In this technology, a HEMS (Home Energy Management System) server transmits schedule information of a customer, an anonymization server anonymizes the schedule information, and the anonymized information is converted into a power usage adjustment server via a network. Send to. The power usage adjustment server broadcasts adjustment information for suppressing demand to the HEMS server based on the anonymized information. Thereby, when schedule information passes from a HEMS server to a power utilization adjustment server, since it is anonymized, a power utilization adjustment server cannot distinguish a specific consumer from the anonymized information.

JP 2012-196055 A

  In patent document 1, since schedule information is anonymized and a specific consumer is not discriminated from schedule information by a third party other than HEMS, privacy infringement can be reduced. However, with the change of the system, retailers enter the electricity retail business, and with this, switching frequently occurs when consumers change contracts with retailers. However, it is conceivable that the schedule information management processing and communication processing increase when the supply and demand adjustment is performed. For example, in the case of electricity, it may take time for adjustment processing to realize constraints to balance supply and demand at 30-minute intervals, such as the same amount for 30 minutes at the same time, which stabilizes energy supply. affect.

  In Patent Literature 1, the power usage adjustment server needs to acquire information of all consumers, and the power usage adjustment server needs to complete the processing for the target consumer within a limited time. In addition, when a consumer switches to another retailer or the like, and the change frequently occurs in the supply and demand adjustment target, the power usage adjustment server needs to repeatedly execute the process of changing the supply and demand adjustment target. As a result, there is a risk that the time for adjusting the supply and demand will exceed a limited time. In addition, since the power usage adjustment server broadcasts demand adjustment information to the HEMS server, it can be considered that the amount of communication processing is enormous.

  In addition, an increase in the number of new businesses is likely to increase or change the number of businesses that handle customer information. For example, a retailer may establish a consortium or group. For this reason, there are cases where a business operator that handles customer information is not a specific power company as in the prior art and does not have a direct contract with the customer, or a contract with a business operator other than the consumer. Even if the operator indicates the contract, there is a risk of privacy management due to a management error of the operator or intentionally taking out information.

  In order to solve the above problems, an energy supply and demand system according to an aspect of the present invention includes a management computer connected to each facility of a plurality of consumers via a communication network. The said management computer memorize | stores the management data containing the information of each consumer's apparatus, and the performance data which shows the track record of use of each apparatus. The management computer selects a candidate consumer group that is a group of consumers that satisfy a consumer condition from the plurality of consumers based on at least one of the management data and the performance data, Based on the management data, candidate data including information on a candidate device that is a consumer device in the candidate consumer group is generated, and the candidate data is transmitted via the communication network.

  When the energy retailer adjusts the demand of the consumer, the amount of information and communication processing of the consumer managed by the retailer can be reduced.

The structure of the supply-and-demand adjustment system of the Example of this invention is shown. The structure of the EMS server 102, the EMS cooperation supply and demand adjustment server 112, and the EMS connection supply and demand adjustment client 122 is shown. The business flow of the supply and demand adjustment system is shown. The cluster listing process is shown. The first cluster extraction process is shown. The 2nd cluster extraction process is shown. A 3rd cluster extraction process is shown. A 4th cluster extraction process is shown. A control command list screen is shown.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  Here, the business form of the energy company which is the premise of the embodiment of the present invention will be described.

  Energy companies' businesses are mainly classified into production (supply), delivery (consignment), and retail. In addition, when each business is separated as a business operator by power system reform or the like, each business is separated as each business operator. It is assumed that the delivery company measures the amount of energy consumed by the consumer, and that the retailer obtains consumer demand information from the delivery company in order to grasp the demand of each individual consumer. It is said. The timing at which the retailer can obtain demand information for a certain period of time has elapsed since the time of demand (for example, we perform weighing, interpolation of missing values, conversion to a message format, extraction of relevant customers from all customers, etc.) After (for example, monthly).

  In this embodiment, it is assumed that a consumer and a retailer enter into an energy supply contract. In addition, it is assumed that a customer owns a measurement control device for an energy management system (EMS) that performs remote control and the like in order to save energy and reduce operation costs of the devices that the user owns. Hereinafter, a retail business operator in energy supply to consumers is referred to as a retail business operator. Strictly speaking, retailers provide customers with the right to use energy, and energy itself is provided to consumers by producers. However, since the retailer and the delivery company make a contract for the delivery, it is assumed that the delivery company and the customer do not make a direct contract.

  In the present embodiment, when the retailer adjusts the supply and demand of the consumer, the supply and demand that the retailer directly adjusts the supply and demand by the partnership between the retailer and the EMS business that manages the customer data. Provide an adjustment system (energy supply and demand adjustment system). The EMS provider clusters the list of consumer devices based on the characteristics of the consumer and provides the list to the retailer. This eliminates the need for the retailer to hold information for identifying the individual of the consumer, thereby reducing the data management cost of the retailer and at the same time reducing the communication processing amount of the consumer.

  This section describes the stakeholders involved in energy management.

  The main stakeholders are EMS (Energy Management), such as retailers that retail energy to consumers, consumers who use energy, and energy consumption of consumer load devices and energy-saving operation and remote control of devices. System), and an EMS business operator. In addition, a generation company (for example, a power generation company) that generates energy from the viewpoint of energy supply, a delivery company (for example, a power transmission and distribution company) that delivers the generated energy to consumers, a bid for energy, There is a trading market (for example, a power trading market) in which bids are traded.

  As a main business, a retailer procures energy from a producer in a transaction market or a mutual transaction. Further, in order to supply the procured energy to the consumer, the retailer enters into a supply contract with the consumer and supplies the energy. In addition, the retailer adjusts the supply so that excess or shortage of demand does not occur from the amount of energy procured. On the other hand, an EMS provider provides EMS such as visualization of energy consumption and energy storage and remote control in customer facilities. Or an EMS provider operates EMS on behalf of a consumer. In addition, the EMS provider provides the retailer with information for requesting the supply and demand adjustment of the customer's equipment.

  Hereinafter, an embodiment of the supply and demand adjustment system when energy is electric power will be described. The energy managed by the supply and demand adjustment system may include gas, heat, water, and the like.

  Here, the stakeholder in power supply and supply-demand adjustment will be described.

  In this embodiment, as a stakeholder, a power generation company generates power, sells power to the power trading market, and a retailer purchases power from the power trading market. At that time, the retailer provides the right to use power to the customer by contract with the consumer, while having the right to adjust the purchased power amount so as not to exceed or surplus every time. It is assumed that it has.

  In order to supply electric power, the retailer requests the transmission / distribution company to transmit power by contract. Further, the customer requests the EMS provider for services such as energy-saving control operation of the load device and remote control of the load device by contract.

  In this embodiment, when a retailer performs power adjustment in cooperation with an EMS provider, the retailer pays a fee for the operation to the EMS provider. As a result, the EMS provider discounts the EMS fee to the consumer who has adjusted the power.

Perform measurement and control. When the customer has a storage battery, the measurement control device 131 may perform measurement and control of the storage battery.

  Hereinafter, the operation of the supply and demand adjustment system of the present embodiment will be described.

  The supply and demand adjustment system is broadly divided into “(1) Pre-registration phase”, “(2) Measurement / analysis phase”, “(3) Clustering phase”, “(4) Supply / demand adjustment phase”, and “(5) Fadeback phase”. Process.

  (1) The pre-registration phase is a phase in which the EMS provider 101 that implements visualization of consumer energy consumption and device control that saves energy registers consumer management data D103. The customer management data D103 includes device data indicating a device held by the customer and customer destination data indicating a transmission destination of a control message for controlling the device.

  In the pre-registration phase, the EMS cooperation supply and demand adjustment client 122 displays the input instruction item of the customer input data on the display device 124 through the WEB page or the like, and acquires the customer input data input to the input device 125 by the consumer. To the EMS server 102. The EMS server 102 receives customer input data from the EMS cooperation supply and demand adjustment client 122, and registers the received customer input data as customer management data D103.

  It is considered that the retailer participates in the control for supply and demand adjustment when the consumer registers the consumer management data D103 in the EMS server 102.

  (2) The measurement / analysis phase is a phase for calculating an adjustable amount that is expected to be adjustable by adjusting supply and demand. The measurement control device 131 measures consumption, power storage, and generated power in a device owned by a consumer. The EMS cooperation supply and demand adjustment client 122 registers the power measured by the measurement control device 131 in the EMS server 102 as power data. Furthermore, the EMS cooperation supply and demand adjustment client 122 registers the control command executed by the measurement control device 131 and the time thereof in the EMS server 102 as control history data. The EMS server 102 calculates an adjustable amount that can be adjusted based on power data, control history data, device data, and the like, and stores it in the supply and demand adjustment data D104.

  This phase is repeated. For example, a 1 minute period, 1 hour period, and 1 day period. Meanwhile, the measurement control device 131 measures and stores the power consumption, the amount of electricity stored, and the amount of power generation. The supply and demand adjustment data D104 may be updated by recalculating the adjustable amount in accordance with changes in the consumption amount, power storage amount, and power generation amount on the customer side.

  (3) The clustering phase is a phase in which the EMS server 102 performs clustering based on customer characteristics. The EMS server 102 creates a control command list including control commands for clustering the consumers based on the customer management data D103 and the usage management data D105 of the customer and controlling the consumer device for each cluster. sign up. This phase is repeated.

  (4) The supply and demand adjustment phase is a phase in which the EMS linked supply and demand adjustment server 112 operated by the retailer carries out supply and demand adjustment toward the consumer.

  When it is determined that the demand amount exceeds the supply amount due to temperature fluctuation or the like with respect to the planned supply amount and the demand amount, or when a request for supply and demand adjustment from the transmission and distribution company is received, A control command list acquisition request for managing supply and demand and adjusting supply and demand is sent to the EMS server 102. The EMS server 102 returns the control command list registered in the clustering phase to the EMS cooperation supply and demand adjustment server 112. The EMS cooperation supply and demand adjustment server 112 transmits a control message to the customer's EMS cooperation supply and demand adjustment client 122 based on the received control command list.

  (5) The feedback phase is a phase in which a rate plan is generated for the consumer based on the results of supply and demand adjustment. The EMS linked supply and demand adjustment server 112 aggregates the results of the supply and demand adjustment performed by the customer, creates a discount plan for each customer cluster based on the aggregated data, and charges to the customer through the EMS provider Notify the plan.

  FIG. 3 shows a business flow of the supply and demand adjustment system.

  Details of each of the pre-registration phase, the measurement / analysis phase, the clustering phase, the supply and demand adjustment phase, and the feedback phase will be described.

  The supply and demand adjustment system is implemented in the order of measurement / analysis phase and clustering phase after the pre-registration phase. However, after the clustering phase is implemented, data changes occur when the customer changes the customer management data D103, uses power, or operates the equipment. It may be implemented in parallel.

  It is assumed that the EMS provider has implemented a service for energy saving operation and remote control of customer equipment by contract with the customer.

  In the pre-registration phase, the supply and demand adjustment system performs customer information acquisition processing for transmitting customer input data from the EMS cooperation supply and demand adjustment client 122 to the EMS server 102 in providing the service (S101). Next, when the communication device 105 of the EMS server 102 receives customer input data, the customer management function P103 performs customer information registration processing for registering the received customer input data as customer management data D103. (S102).

  The customer input data includes device data. For example, the device data when the device is the load device 132 can access the device name (or type) of the device, the model number of the device, the rated output (or rated power consumption) of the device, and the device. Control IP address which is the address of the measurement control device 131 and the control command of the device. Further, for example, the device data when the device is the power generation device 133 includes the power generation output (or capacity) of the device. For example, the device data when the device is a storage battery includes the storage capacity (or capacity) of the device.

  Here, the pre-registration phase will be described using a specific example.

  The processing device 113 of the customer's EMS cooperation supply and demand adjustment client 122 causes the device data of the customer's device to be transmitted to the EMS server 102 via the Internet 171 using the communication device 115. This device data includes a device name “air conditioner”, a model number “XXX_YYY_MM” of the device, a rated output “1200 W” of the device, and a control IP address “10.100.200.001” of the device. . Instead of the control IP address, other control identification information for the EMS cooperation supply and demand adjustment client 122 to identify the device may be used. The EMS cooperation supply and demand adjustment client 122 stores the association between the control identification information and the control IP address, converts the control identification information from the EMS cooperation supply and demand adjustment server 112 into a control IP address, and performs measurement control using the control IP address. A control command may be transmitted to the device 131.

  When the communication device 105 of the EMS server 102 receives the device data, the processing device 103 stores the received device data and the device ID indicating the device in the customer management data D103 of the storage device 104 by the customer management function P103. To do. Further, the customer management function P103 uses the identification information of the transmission source EMS cooperation supply and demand adjustment client 122, for example, the client IP address “10.100.200.101”, which is an IP address, as the customer destination data, the storage device 104. Stored in the customer management data D103. Instead of the client IP address, other identification information such as a MAC address that can identify the EMS cooperation supply and demand adjustment client 122 may be used. The customer destination data may include information such as the contact information of the retailer necessary for business, the contact information of the customer, and the type of energy used.

  In the device data of this embodiment, data for one device is held in one record. At the time of device data registration, the customer management function P103 obtains the largest device ID in the customer management data D103 and adds “1” to the value to obtain the ID of the registered device data. The last record is added to the customer management data D103. When the initial value is not stored in the customer management data D103, the customer management function P103 assigns a preset device ID such as “001”. The consumer management function P103 may transmit the numbered device ID to the EMS cooperation supply and demand adjustment client 122 as a response to the device data. Here, the customer management function P103 registers device data for each device. However, when the customer has a plurality of devices, the customer management function P103 includes a device list including a plurality of device data. The device data may be registered together. At that time, the processing apparatus 103 may repeatedly execute the customer management function P103.

  When updating the registered device data, the customer management function P103 receives the updated device data and its device ID from the EMS cooperation supply and demand adjustment client 122, and corresponds to the device ID in the customer management data D103. Update the record to be updated.

  In the measurement / analysis phase, the supply and demand adjustment system calculates an adjustable amount that is expected to be demand adjustable.

  The EMS server 102 performs power usage amount acquisition processing for receiving power data indicating the amount used by the customer, the amount generated, the amount stored, the operation of the device, and the like from the EMS cooperation supply and demand adjustment client 122 (S111). . Next, the EMS server 102 performs a power usage amount information registration process (S112) for registering the acquired power data in the storage device 104, and calculates an adjustable amount based on the device data. S113) is executed, and a customer management information registration process (S114) for registering the adjustable amount in association with the device data is executed.

  Here, the measurement / analysis phase will be described using a specific example.

  In the power consumption acquisition process S <b> 111, the EMS cooperative supply and demand adjustment client 122 acquires power data from the measurement control device 131 and transmits the acquired power data to the EMS server 102 via the communication device 126. The power data includes the time of use “201510101 — 10:00:00” of the past customer, the power amount “100”, the client IP address “10.100.200.001”, and the like. The time here indicates, for example, the measurement start time of the electric energy measured in units of 30 minutes. In addition, the EMS cooperation supply and demand adjustment client 122 includes, together with power data, measurement data measured by a sensor attached to the measurement control device 131, and a control history indicating control by pressing a control button of the measurement control device 131. Data may be sent to the EMS server 102. The measurement data may include outside air temperature information “38 ° C.”, room temperature “18 ° C.”, and the like. The control history data may include a control time “20151010_10: 00: 10”, a control command “DOWN” corresponding to the control button of the device, a control IP address “10.100.200.001” corresponding to the device, and the like. Good.

  When the performance data is received by the communication device 105 of the EMS server 102 in the power usage information registration processing S112, the performance data received by the processing device 103 by the usage management function P105 is stored in the usage management table D105 of the storage device 104. To do. Here, an example is shown in which the performance data is registered in units of equipment, not in units of consumers. However, the EMS server 102 uses the client IP address of the consumer as a main key, and N devices are held by the consumer. By registering in association with the control IP address corresponding to, devices may be managed on a per-customer basis.

  In the demand adjustment amount management process S113, for example, the EMS server 102 calculates an adjustable amount, which is electric power that can be adjusted by device control, based on the power data acquired by the supply and demand adjustment amount management function P104. For example, since the EMS server 102 calculates a decrease in power consumption by “DOWN” of a control command at a certain point in time for a certain device, before the control is performed (for example, 30 minutes before the control), the power usage, and after the control is performed. A difference value “100” from the power usage amount (for example, 30 minutes after pressing) is calculated as an adjustable amount. Note that if the EMS server 102 determines that a certain device is controlled for demand adjustment when measuring power usage based on the control history data, the EMS server 102 reduces the controllable amount of the device by control. A new adjustable amount may be calculated by reducing the amount of power used (demand adjustment amount). When the device is the load device 132, the EMS server 102 may calculate the actual amount of power usage as an adjustable amount. When the device is the power generation device 133, the EMS server 102 may calculate the adjustable amount by subtracting the actual power generation output from the rated output.

  In the customer management information registration process S114, the EMS server 102 associates the adjustable amount with the control IP address corresponding to the device and registers it in the customer management data D103 by the customer management function P103. Here, an example has been shown in which the adjustable amount is registered in units of devices, not in units of consumers. However, the EMS server 102 uses the client IP address of the customer as a main key, and the N pieces of information held by the customer are stored. By registering in association with the control IP address of the device, the device can be managed in units of customers.

  The clustering phase is a phase in which the EMS server 102 clusters customers based on the characteristics of the customers.

  The EMS server 102 clusters customers based on features such as device data and performance data, generates a control command list for controlling customer devices for each cluster, and registers a control command list. A listing process is executed (S121). This phase is repeated.

  A plurality of cluster extraction processes are set in advance. The retailer selects one cluster extraction process as a specific cluster extraction process from a plurality of cluster extraction processes according to the situation, and inputs it to the EMS cooperation supply and demand adjustment server 112. The retailer selects a cluster extraction process that is considered to be suitable for an environment in which supply and demand adjustment is performed, such as ease of implementation and certainty. For example, the retailer selects a cluster extraction process for calculating a cluster in which the temperature difference between the room and the room is large with respect to the time when the summer temperature is high.

  The EMS cooperation supply and demand adjustment server 112 transmits designation data indicating the specific cluster extraction process to the EMS server 102. The EMS server 102 manages each algorithm of a plurality of cluster extraction processes as a module, and the algorithm can be replaced by calling a module for the specific cluster extraction process.

  FIG. 4 shows the cluster listing process.

  The cluster listing function P102 of the EMS server 102 uses the client IP address as customer identification information. Thereby, the EMS server 102 can perform the process for every consumer. Further, the cluster listing function P102 acquires a control IP address associated with the client IP address based on the customer management data D103. Thereby, the EMS server 102 can perform the process for every apparatus.

  First, the cluster listing function P102 executes a specific cluster extraction process selected from a plurality of cluster extraction processes (S303).

  Next, the cluster listing function P102 acquires, from the customer management data D103, a control command for the device corresponding to the customer in the cluster obtained by the specific cluster extraction process, and from the demand / supply adjustment data D104, the demand Data acquisition processing for acquiring the adjustable amount of the house is executed (S305). Here, the cluster listing function P102 acquires the control command of the device corresponding to the control IP address by searching the customer management data D103 based on the control IP address associated with the client IP address in the cluster. To do. Further, the cluster listing function P102 retrieves the supply and demand adjustment data D104 based on the control IP address associated with the client IP address in the cluster, thereby acquiring the adjustable amount of each device of the consumer. For example, the cluster listing function P102, for each device corresponding to the client IP address, “control IP address: 10.100.200.001”, “control command: DOWN”, “adjustable amount: 100”. To get.

  Thereafter, the cluster listing function P102 associates the client IP address in the cluster, the control IP address of the device corresponding to the client IP address, the control command of the device, and the adjustable amount of the device. A list generation process for storing the command list in the list management data D102 is performed (S306). In other words, the control command list includes a client IP address and a control IP address corresponding to a candidate for a consumer that is a target of supply and demand adjustment. Note that the cluster list creation function P102 may manage a cluster name for a cluster by attaching it to a control command list when generating a plurality of clusters using a plurality of cluster extraction processes. For example, the control command list includes “cluster name: EMS temperature difference cluster”, “IP address: 10.100.200.001”, “control command: DOWN”, and “adjustable amount: 100”. The above is the cluster list processing.

  Here, details of each cluster extraction process will be described.

  When the first cluster extraction process is selected as the specific cluster extraction process, the cluster listing function P102 executes the following first cluster extraction process in S303 described above.

  FIG. 5 shows the first cluster extraction process.

  The cluster listing function P102 sequentially selects client IP addresses corresponding to consumers, and acquires consumer power data corresponding to the selected client IP addresses from the usage management data D105. Is executed (S411). Here, the cluster listing function P102 searches the usage management data D105 using the customer's control IP address as a primary key, thereby acquiring power data corresponding to the customer's control IP address. The cluster listing function P102 may further acquire control history data and measurement data of the consumer. Here, when the number of records to be acquired becomes enormous, the cluster listing function P102 specifies each time (time zone) as a search condition and acquires each data.

  Thereafter, the cluster listing function P102 executes a power usage amount calculation process for setting a specific time zone and calculating the power usage amount of the consumer in the specific time zone based on the acquired power data ( S412). The specific time zone is expressed as, for example, 10:30 on January 1, 2015.

  Thereafter, the cluster listing function P102 determines whether a client IP address corresponding to all customers has been selected (S413). As a result of S413, when it is determined that the client IP addresses corresponding to all customers have not been selected (NO), the cluster listing function P102 shifts the process to S411 and selects the next client IP address. . As a result of S413, when it is determined that the client IP addresses corresponding to all customers have been selected (YES), the cluster listing function P102 shifts the processing to the next S414.

  Thereafter, the cluster listing function P102 generates an evaluation list indicating the client IP address and power usage of each consumer, and generates a priority list by sorting the power usage list in descending order of power usage. The cluster listing function P102 selects a predetermined reference number of client IP addresses in order from the top of the priority list, and registers the selected client IP addresses in the cluster customer list, so that the customer cluster A cluster registration process is generated (S414). The reference number is, for example, 10% of the total number of consumers. The reference number may vary in accordance with the number of consumers, the number of devices, the demand amount, and the supply amount. Note that the cluster listing function P102 may set a reference value for the power usage amount in advance and register customers whose power usage value exceeds the reference value in the cluster customer list.

  According to the first cluster extraction process described above, the EMS server 102 selects the client IPs of some consumers suitable for desired demand adjustment from among a plurality of consumers based on the power usage for each consumer. An address can be selected. The customer condition that is the condition of the consumer registered in the cluster in the first cluster extraction process can be expressed as the rank of the power usage amount for each consumer being within the reference number from the top.

  When the second cluster extraction process is selected as the specific cluster extraction process, the cluster listing function P102 executes the following second cluster extraction process in S303 described above.

  FIG. 6 shows the second cluster extraction process.

  The cluster listing function P102 sequentially selects client IP addresses corresponding to the consumers, and the outside air temperature measured by the consumer measurement control device 131 corresponding to the selected client IP address from the usage management data D105. And the EMS data acquisition process which acquires the measurement data containing room temperature is performed (S421). Here, the cluster listing function P102 searches the usage management data D105 using the consumer's control IP address as a primary key, thereby acquiring measurement data corresponding to the consumer's control IP address.

  Thereafter, the cluster listing function P102 sets a specific time zone, and calculates an inside / outside air temperature difference that is a difference between the outside air temperature and the room temperature of the consumer in the specific time zone based on the acquired measurement data. An inside / outside air temperature difference calculation process is executed (S422).

  Thereafter, when it is determined that the client IP addresses corresponding to all customers have not been selected (S423: NO), the cluster listing function P102 moves the process to S421 and selects the next client IP address. . When it is determined that the client IP addresses corresponding to all the consumers have been selected (S423: YES), the cluster listing function P102 generates an evaluation list indicating the client IP address of each customer and the inside / outside temperature difference, A priority list is generated by sorting the evaluation list in order from the largest temperature difference between inside and outside. The cluster listing function P102 selects a predetermined reference number of client IP addresses in order from the top of the priority list, and registers the selected client IP addresses in the cluster customer list, so that the customer cluster A cluster registration process is executed (S424). The cluster listing function P102 may set a reference value for the internal / external temperature difference in advance, and register customers whose internal / external temperature difference exceeds the reference value in the cluster consumer list.

  According to the second cluster extraction process described above, the EMS server 102 selects the client IPs of some consumers suitable for desired demand adjustment from among a plurality of consumers based on the temperature difference between the inside and outside of each customer. An address can be selected. The customer condition corresponding to the second cluster extraction process can be expressed as that the rank of the temperature difference between the inside and outside of the facility for each customer is within the reference number from the top.

  When the third cluster extraction process is selected as the specific cluster extraction process, the cluster listing function P102 executes the following third cluster extraction process in S303 described above.

  FIG. 7 shows the third cluster extraction process.

  The cluster listing function P102 selects the client IP address corresponding to the customer in order, and acquires the names of all the devices of the customer corresponding to the selected client IP address from the customer management data D103. An acquisition process is executed (S431). Here, the cluster listing function P102 searches the customer management data D103 using the customer's control IP address as a primary key, thereby acquiring the name of the device corresponding to the customer's control IP address.

  Thereafter, the cluster listing function P102 sets a specific device name, and calculates a holding ratio that is a ratio of the number of devices of the specific device name to the number of devices held by the consumer based on the acquired device name. The specific device ownership ratio calculation process is executed (S432).

  Thereafter, when it is determined that the client IP addresses corresponding to all customers have not been selected (S433: NO), the cluster listing function P102 moves the process to S431 and selects the next client IP address. . When it is determined that the client IP addresses corresponding to all customers have been selected (S433: YES), the cluster listing function P102 generates an evaluation list indicating the client IP addresses of each customer and the specific equipment possession ratio. The priority list is generated by sorting the evaluation list in descending order of the specific device possession ratio. The cluster listing function P102 selects a predetermined reference number of client IP addresses in order from the top of the priority list, and registers the selected client IP addresses in the cluster customer list, so that the customer cluster A cluster registration process is generated (S434). The cluster listing function P102 may set a reference value for the specific equipment ownership ratio in advance, and register customers whose specific equipment ownership ratio exceeds the reference value in the cluster customer list.

  According to the third cluster extraction process described above, the EMS server 102 is a client of some customers suitable for desired demand adjustment from among a plurality of customers based on the specific equipment holding ratio for each customer. An IP address can be selected. The customer condition corresponding to the third cluster extraction process can be expressed as that the rank of the specific equipment holding ratio for each customer is within the reference number from the top.

  Here, a specific example of the specific device holding ratio will be described. First, the cluster listing function P102 uses the control IP address as a search key from the customer management data D103, and the device name “air conditioner”, model number “XXX_YYY_MM”, and rated output “1200W” of the device held by the customer. Is acquired (S421). Thereafter, the cluster listing function P102 sets the specific device as “air conditioner”, and calculates, for each customer, the number of devices as the number of control IP addresses and the number of specific devices as the number of device names “air conditioner”. (S422). For example, the cluster listing function P102 regards the client IP address “10.100.200.101” as one consumer, and among the devices associated therewith, the control IP address of the device whose device name is “air conditioner” “10.100.200.001” and “10.100.200.002” are acquired. Next, the cluster listing function P102 calculates a specific device possession ratio that is a ratio of the number of specific devices from the acquired number of devices of each consumer (S422). For example, when the number of devices associated with the customer having the client IP address “10.100.200.101” is 10, and among them, there are 2 “air conditioners”, the specific device holding ratio is 20%.

  When the fourth cluster extraction process is selected as the specific cluster extraction process, the cluster listing function P102 executes the following fourth cluster extraction process in S303 described above.

  FIG. 8 shows the fourth cluster extraction process.

  The cluster listing function P102 sequentially selects the client IP address corresponding to the consumer, and acquires the power usage amount of the consumer corresponding to the selected client IP address for each time zone from the usage management data D105. The EMS data acquisition process is executed (S441). Thereafter, the cluster listing function P102 executes a peak time zone selection process for selecting a peak time zone of the power usage amount of the consumer (S442).

  Thereafter, when it is determined that the client IP addresses corresponding to all customers have not been selected (S443: NO), the cluster listing function P102 moves the process to S441 and selects the next client IP address. . If it is determined that the client IP address corresponding to all customers has been selected (S443: YES), the cluster listing function P102 sets a specific time zone, and the peak time zone is specified from among all customers. A cluster registration process for generating a customer cluster is performed by selecting the client IP address of the customer in the time zone and registering the selected client IP address in the cluster customer list (S444). The specific time zone is, for example, a time zone in which power supply and demand is tight or a time zone in which the temperature reaches a peak in summer.

  According to the fourth cluster extraction process described above, the EMS server 102 selects the client IPs of some consumers suitable for desired demand adjustment from a plurality of consumers based on the peak time zone for each customer. An address can be selected. The customer condition corresponding to the fourth cluster extraction process can be expressed as a peak time zone for each customer being a specific time zone.

  In addition to this, the plurality of cluster extraction processes may include, for example, a cluster extraction process in which the customer condition is that the peak power of the consumer is greater than or equal to a preset peak power threshold.

  According to these cluster extraction processes, the EMS server 102 is suitable for desired demand adjustment from a plurality of consumers based on at least one of the customer management data D103 and the usage management data D105. Some consumers can be selected as clusters.

  This is the clustering phase.

  According to the clustering phase, the retailer 111 can select an appropriate cluster extraction process and acquire appropriate candidate information by the cluster extraction process.

  The supply and demand adjustment phase is a phase in which the EMS linked supply and demand adjustment server 112 is triggered to perform supply and demand adjustment.

  The supply / demand management function P118 of the EMS cooperative supply / demand adjustment server 112 determines, for example, whether supply / demand adjustment is necessary based on the supply amount and the demand amount planned due to temperature fluctuations. The determination result may include a necessary adjustment amount that is a demand amount to be reduced. For example, the supply and demand management function P118 determines that the supply and demand adjustment is necessary when the ratio of the demand amount to the supply amount exceeds a preset threshold value. The supply and demand management function P118 may perform supply and demand adjustment in response to a request for supply and demand adjustment from the power transmission and distribution company 161 or the like. Based on the determination result, the retailer 111 inputs a supply and demand adjustment instruction to the supply and demand management function P118.

  In response to the instruction, the EMS cooperative supply and demand adjustment server 112 performs control command list acquisition request processing for requesting (requesting) acquisition of a control command list for the cluster to the supply and demand management function P101 of the EMS server 102 (S131).

  Upon receipt of the request, the supply and demand management function P101 of the EMS server 102 acquires the cluster customer list from the list management data D102, and adjusts the control IP address and control command corresponding to the client IP address indicated in the cluster customer list A list provision process is performed in which the available amount is acquired and the control command list is transmitted to the EMS cooperation supply and demand adjustment server 112 (S132).

  Thereby, the EMS server 102 can transmit the information which shows the apparatus of the consumer selected as the candidate of the object of supply and demand adjustment to the EMS cooperation supply and demand adjustment server 112. Further, the retailer 111 can select a supply and demand adjustment target from the information received from the EMS server 102.

  In the clustering phase, the EMS server 102 may calculate a plurality of clusters by a plurality of cluster extraction processes and generate a plurality of control command lists corresponding to the plurality of clusters, respectively. In this case, in the supply and demand adjustment phase, the EMS cooperation supply and demand adjustment server 112 displays information indicating the characteristics of each of the plurality of clusters on the display device 114. The retailer 111 selects and inputs a cluster that matches the supply and demand adjustment environment from the displayed clusters. The EMS cooperation supply and demand adjustment server 112 transmits a control command list acquisition request including designation data for designating the selected cluster to the EMS server 102. The EMS server 102 transmits a control command list corresponding to the cluster indicated in the designated data to the EMS cooperation supply and demand adjustment server 112. In this case, the retailer 111 can select an appropriate cluster for the situation at the time of supply and demand adjustment.

  Next, the list discrimination management function P119 of the EMS cooperation supply and demand adjustment server 112 displays the received control command list on the control command list screen of the display device 114, and performs an input for selecting an item to be controlled by the retailer. Then, a list determination management process for holding the information in the storage device is performed (S133).

  FIG. 9 shows a control command list screen.

  The control command list screen includes a control command list 508. The control command list 508 is a list of control commands for consumer devices included in the cluster. The control command list 508 is displayed in a table format and has a record for each device. The record corresponding to one device includes a check button 501 for selecting whether or not to set the device as a supply and demand adjustment target, an item number (#) 502 of the device, and a control IP address 303 corresponding to the device. And a control method 504 indicating a control command for controlling the device, and an adjustable amount (W) 505 that is expected to be adjusted by supply and demand adjustment of the device. The control command list screen further includes a total value 506 of the adjustable amount of the target device selected by the check button 501. The control command list screen further includes an execution button 507 for executing a control command and adjusting supply and demand. The control command list screen may include supplementary information that serves as a reference for selection, such as past execution requests and results. When the control command of the target device is “DOWN”, it is possible to reduce the output of the target device and reduce the amount of power used for the adjustable amount. When the control command of the target device is “CUT” or “OFF”, it is possible to stop the target device and reduce the amount of power used for the adjustable amount. The expression of the control command depends on the type and model name of the target device.

  According to this control command list screen, the retailer can select a target device to be subject to supply and demand adjustment from the control command list 508 based on the adjustable amount and the control method. Further, the control command list screen displays the total value 506 of the adjustable amount of the selected target device, so that the retailer can select the target device until the necessary adjustment amount is secured. Further, it is possible to prevent the number of target devices and the total of adjustable amounts from becoming excessive, thereby increasing the processing amount and communication amount. When the EMS cooperation supply and demand adjustment server 112 transmits a request for the control command list to the EMS server 102, the retailer 111 can acquire the control command list when it is determined that the supply and demand adjustment is necessary. In the case where it is necessary to quickly adjust supply and demand, the EMS linked supply and demand adjustment server 112 does not use the input of the retailer 5 and selects the target device from the control command list until the necessary adjustment amount is secured. You may choose.

  Next, the control command execution function P120 of the EMS cooperation supply and demand adjustment server 112 specifies the control IP address “10.100.200.001” of the target device selected by the retailer on the control command list screen, and the control command The client IP address “10.100.200.101” associated with the specified control IP address is acquired from the list.

  The control command execution function P120 converts the control command of the target device into a control message “10.100.200.001, DOWN” that can be interpreted by the EMS cooperation supply and demand adjustment client 122, and transmits the control message to the acquired client IP address. Then, the control execution process is executed (S134). When a plurality of target devices selected from the control command list are associated with a plurality of client IP addresses, the EMS cooperation supply and demand adjustment server 112 transmits a corresponding control message to each of the plurality of client IP addresses. The EMS cooperation supply and demand adjustment server 112 transmits a control message to some of the customers corresponding to the target device among all the customers, and transmits a control command to each target device as a control message for each customer. As a result, the amount of communication can be reduced. Here, the EMS cooperation supply and demand adjustment server 112 transmits a control message to the EMS cooperation supply and demand adjustment client 122 corresponding to the client IP address, but the measurement control apparatus indicated by the control IP address “10.100.200.001”. A control message may be transmitted to 131. In this case, the processing amount of the EMS cooperation supply and demand adjustment client 122 can be suppressed.

  Next, the EMS cooperation supply and demand adjustment client 122 receives the control message, and executes a device control execution process in which the control command included in the control message is transmitted to the measurement control device 131 of the control IP address included in the control message. (S135). Here, the EMS cooperation supply and demand adjustment client 122 acquires the control command “DOWN” from the control message by dividing the received control message into control commands for each device. Furthermore, the measurement control device 131 executes control of the target device by converting the control command into a device command that can be interpreted by the target device, such as binary or “0x11”, and transmitting the device command to the target device. To do. When the control message includes the control command of the target device and the control IP address of the measurement control device 131 connected to the target device, the EMS cooperation supply and demand adjustment client 122 transmits the control command to the measurement control device 131. be able to.

  The feedback phase is a phase in which a rate plan is generated for the consumer based on the supply and demand adjustment results.

  In the control execution process S134, the EMS cooperation supply and demand adjustment server 112 counts the number of times each device is selected as the target device, and based on the number of times, performs the control for supply and demand adjustment for each customer. A certain number of power adjustments is calculated, and the number of power adjustments is stored in the storage device 117. The charge plan creation function P121 calculates a charge plan that indicates a discount or return amount for a cluster based on price information such as actual unit price and unit price of owned equipment and the number of power adjustments determined in advance. The process is executed (S141). For example, the EMS cooperation supply and demand adjustment server 112 stores the supply and demand adjustment history for the cluster during the control execution process of S134, and counts the number of power adjustments in the cluster within a preset history period based on the history. . In this case, if a reduction amount of 10 yen is set in advance for one control for supply and demand adjustment for one device, and a total of 10 controls are performed in a month in the cluster, The plan creation function P121 calculates a monthly plan with a return amount of 100 yen for the cluster. Further, the charge plan creation function P121 may calculate a charge plan based on the ratio of the number of specific types of devices (specific device ownership ratio) to the number of all types of devices held by the consumer.

  Thereafter, the charge plan creation function P121 displays a charge plan message including a client IP address “10.100.200.001” included in the cluster and a charge plan such as a reduction amount “100 yen monthly discount charge plan” for the cluster. Is transmitted to the EMS server 102, and a plan providing process is executed (S142).

  When receiving the price plan message, the EMS server 102 acquires the client IP address from the price plan message. The EMS server 102 executes a plan notification process in which fee data indicating a fee plan is transmitted to the acquired client IP address (S143). The EMS cooperative supply and demand adjustment client 122 that has received the charge data executes a plan display process for causing the display device 124 to display a charge plan to be applied from the next month based on the charge data (S144). The EMS provider applies a rate plan to the customer's EMS fee, thereby discounting the EMS fee.

  According to this feedback phase, the EMS cooperative supply and demand adjustment server 112 can calculate a rate plan without specifying a consumer by calculating a rate plan for the cluster. In addition, the EMS server 102 receives information indicating the charge plan of the cluster from the EMS cooperative supply and demand adjustment server 112, and transmits information indicating the charge plan to the EMS cooperative supply and demand adjustment client 122 corresponding to the customers in the cluster. Thus, it is possible to provide a charge plan reflecting the results of power adjustment by the cluster to consumers in the cluster. Note that the EMS cooperative supply and demand adjustment server 112 may store a power adjustment history for each client IP address and calculate a rate plan for each client IP address in the cluster.

  This completes a series of operations of the supply and demand adjustment system. Thereafter, each phase is repeatedly performed asynchronously and appropriately.

  In addition, each operation may be carried out by one person in charge of a retailer or one person in charge of a customer, a member of a department in charge of multiple retailers, a family of customers, It may be carried out by each of a plurality of persons such as employees.

  When a retailer or a customer participates in the supply and demand adjustment system, the supply and demand adjustment system may execute identity verification and user authentication. For example, the supply and demand adjustment system performs participation registration by certification work from a public institution and authenticates with a login ID and password.

  In the above-described embodiment, the EMS linked supply / demand adjustment client 122 of the consumer transmits data to the EMS server 102 of the EMS provider, and the EMS linked supply / demand adjustment server 112 of the retailer sends a control message. Is transmitted to the customer's EMS linked supply and demand adjustment client 122. The push method is used. The EMS server 102 transmits a data acquisition request to the EMS cooperation supply and demand adjustment client 122. The pull method and the EMS cooperation supply and demand adjustment client 122 transmit a control message acquisition request to the EMS cooperation supply and demand adjustment server 112. A pull method may be used.

  Note that the supply and demand adjustment system may not include the EMS cooperation supply and demand adjustment client 122. In this case, in the supply and demand adjustment phase, the EMS cooperation supply and demand adjustment server 112 transmits a control message to the control IP address in the cluster.

  According to the present embodiment, the EMS server 102 converts customer information into a control command list including a destination and a control command for each cluster, and transmits the control command list to the EMS cooperation supply and demand adjustment server 112. By supplying a control message to the destination based on the control command list, the supply and demand adjustment server 112 can keep customer information in the EMS server 102, and can reduce leakage of privacy information. For example, a retailer obtains a power usage amount for a preset measurement period from a power transmission / distribution business operator, but obtains a load curve indicating a change in the power usage amount during the measurement period from a customer or an EMS business operator. Do not get. In the present embodiment, in order to indicate consumers classified as clusters, information transmitted from the EMS provider to the retailer is a client IP address corresponding to the consumer, and information and demand for identifying the consumer It does not include information on the privacy of consumers, such as information indicating the house's road curve. Thereby, the retailer does not need to manage information related to the privacy of the consumer in order to select the target of supply and demand adjustment. In addition, the retailer calculates a rate plan corresponding to the supply and demand adjustment history for the cluster, and transmits information indicating the rate plan to the EMS provider. This eliminates the need for retailers to manage information about consumer privacy in order to calculate rate plans.

  According to the present embodiment, the EMS server 102 selects some consumers as a cluster based on the power usage characteristics of the consumers, and controls the devices in the cluster.
