Description

  The present invention relates to a technique for managing the operation of a plurality of facilities.

  In the next-generation power network, the power supply from the supply side to the demand side is not unilaterally provided from the current supply side to the demand side. To achieve energy saving, peak shift, power outage countermeasures, and environmental load reduction.

  As means for this, each consumer and electric power company has a demand management device such as a HEMS (Home Energy Management System) and a CEMS (Community Energy Management System). The demand management device monitors the state of consumer electronic devices and facilities, communicates with external devices via a communication network, and adjusts the power supply and demand of the system. The demand management device enables smooth power interchange between customers and the supply side, and as a result, smooth system stabilization can be performed. For example, in peak shift, requests and negotiations for changing the usage time zone of a device, suppressing power consumption for a certain period of time, power interchange, etc., and execution management are performed via a demand management device. This makes it possible to smoothly negotiate the power interchange between consumers and execute the power interchange. As a result, it is possible to avoid power failure and waste of power consumption.

  As a technique for realizing such supply and demand adjustment, a power supply system that distributes electric power stored in a shared storage battery according to the priority of a consumer is known (for example, Patent Document 1).

JP 2011-208771 A

  However, for example, the priority of the consumer as described above is set as a fixed value by the system administrator when the power supply system is constructed, so it cannot cope with a change in needs due to a change in the lifestyle of the consumer in the community. . For example, in a community with a small number of electric vehicles (EVs) owned by consumers and a large number of gasoline vehicles, the priority of the EV station is considered to be set lower than the priority of the gas station. . In the future, however, if customers change from gasoline cars to EVs, the setting will be inappropriate. As a result, there is a possibility that power is preferentially supplied to a gas station that is rarely used in practice, leading to wasted power.

  That is, when a facility whose operation is restricted is selected from a plurality of facilities, a change in the usage status of the facility is not considered.

  In order to solve the above-described problem, a facility management method according to one aspect of the present invention stores the amount of equipment used in the facility in each of the plurality of facilities, and the facility management method in each of the plurality of facilities. A facility that identifies other facilities related to the device, calculates the usage level indicating the usage status of the other facility based on the usage, and restricts operation from the multiple facilities based on the usage level of multiple facilities Comprising selecting.

  The necessity of operation of other facilities related to the device can be determined in accordance with the amount of use of the device belonging to a certain facility.

  FIG. 5 shows a linking request in the first embodiment. The linking request includes several linking request destination classifications which are real equipment device classifications associated with the requesting customer facility 130. In this example, it is assumed that a gas station GS that is another customer facility transmits a linking request. The requesting customer facility 130 is a gas station GS, and the linking request destination classification is a car, a motorcycle, or an oil stove that is considered to be closely related to the gas station GS. Further, the linking request may include the customer facility classification of the customer facility 130 that is the linking request source, the name of the customer facility 130 that is the linking request source, and the like. In this example, the customer facility classification of the linking request source is a gas station, and the customer facility name of the linking request source is a gas station GS.

  Details of the virtual device registration process in S301 will be described below.

  FIG. 6 shows a virtual device registration process.

  In S400, the device registration unit 201 recognizes the customer demand management device 100 of another customer facility. Here, the device registration unit 201 recognizes the customer demand management device 100 of another customer facility via the communication network 120. In this recognition, the device registration unit 201 uses, for example, a device having a GPS function, such as a portable terminal of a consumer who is the owner or a car navigation device of a car of the consumer. In this case, the device registration unit 201 receives a movement history of a customer from a device having a GPS function via a communication network such as a LAN (Local Area Network) and collates it with map information stored in advance in a storage device. Thus, the other customer facility visited by the customer may be specified, and the customer demand management device 100 of the specified other customer facility may be recognized via the communication network 120. Further, the consumer may designate the consumer demand management device 100 of another customer facility via the input / output unit 103.

  In step S <b> 401, the device registration unit 201 receives an association request from the customer demand management device 100 of another customer facility via the communication network 120 and stores it in the secondary storage device 105.

  In step S <b> 402, the device registration unit 201 selects one unselected real device from the real device information in the secondary storage device 105 as a target real device, and stores the real device information of the target real device as a secondary. Read from the storage device 105.

  In step S <b> 403, the device registration unit 201 compares the real device classification in the real device information of the target real device with the association request destination classification in the received association request, and records the comparison result in the main storage device 104. To do.

  In step S <b> 404, the device registration unit 201 determines whether the processing in step S <b> 402 has been performed for all real devices.

  When the result of S404 is No, the device registration unit 201 shifts the process to S402.

  If the result of S404 is Yes, the device registration unit 201 moves the process to S405.

  In step S <b> 405, the device registration unit 201 determines whether the real device classification of at least one real device matches the association request destination classification based on the comparison result.

  If the result of S405 is No, the device registration unit 201 ends this flow.

  If the result of S405 is Yes, the device registration unit 201 moves the process to S406.

  In step S <b> 406, the device registration unit 201 requests the user of the consumer demand management apparatus 100 to input consent for registering the other customer facility indicated in the association request as a virtual device. At this time, the input / output unit 103 displays, for example, a screen requesting consent.

  In step S <b> 407, the device registration unit 201 determines whether the user's consent has been obtained based on the input to the input / output unit 103.

  If the result of S407 is No, the device registration unit 201 ends this flow.

  If the result of S407 is Yes, the device registration unit 201 moves the process to S408.

  In step S <b> 408, the device registration unit 201 registers the virtual device information indicating the virtual device in the secondary storage device 105 as a virtual device that is the other customer facility of the association request source. Further, the real device information in the secondary storage device 105 and the virtual device information are combined into device information. The virtual device information includes the customer facility classification of the request source of the association request. Here, the registration consent confirmation of the consumer is configured to obtain the input of the user of the consumer demand management apparatus 100 each time. For example, the consumer consents in advance to the registration of the virtual device. For example, this input operation is not necessary.

  The above is the flow of the virtual device registration process.

  FIG. 7 shows device information in the first embodiment. The device information has an entry for each device. The device is either a real device or a virtual device. The entry of the real device is the same as the real device information. The entry of a certain virtual device has the same format as the entry of a real device, and includes the ID of the virtual device in the device information, the name of another customer facility corresponding to the virtual device, and the device classification of the device. Including. The device classification in this case is a virtual device. The device information in this example has an entry for the gas station GS, which is a virtual device, in addition to the same entry as the real device information.

  Here, it returns to description of the flow of customer facility management processing.

  In step S <b> 302, the device association unit 202 performs association between devices, generates association information indicating the association, and stores the association information in the secondary storage device 105. Here, the device association unit 202 performs association between the real device and the virtual device registered in the consumer demand management apparatus 100.

  Here, the device linking unit 202 unconditionally links a virtual device of another customer facility that has issued a linking request designating the actual device classification of the consuming device with the consuming device, For example, a related virtual device may be selected and linked. Here, from the viewpoint of preventing registration of other customer facilities that are less relevant to the customer's equipment, and reducing the labor of the customer's own equipment, the equipment associating unit 202 is the existence of the customer's equipment. When the equipment classification matches the actual equipment classification requested by the other consumer facility, the self-customer equipment and the other consumer facility are linked.

  Details of the linking process in S302 will be described below.

  FIG. 8 shows the linking process.

  In step S <b> 501, the device association unit 202 reads the association request received in step S <b> 401 from the secondary storage device 105.

  In step S <b> 502, the device association unit 202 selects one real device that has not been selected from the real device information in the secondary storage device 105 as a target real device, and sets the real device information of the target real device as the secondary. Read from the storage device 105.

  In step S <b> 503, the device association unit 202 determines whether the actual device classification of the selected actual device is included in the association request destination classification of the received association request.

  If the result of S503 is No, the device associating unit 202 shifts the process to S507.

  When the result of S503 is Yes, the device associating unit 202 shifts the process to S504.

  In step S <b> 504, the device associating unit 202 requests the customer to input consent for associating the selected real device with the other customer facility indicated in the associating request. At this time, for example, the input / output unit 103 displays a screen for inputting whether or not to agree.

  In step S <b> 505, the device associating unit 202 determines whether or not the customer's consent has been obtained based on the input to the input / output unit 103.

  If the result of S505 is No, the device associating unit 202 shifts the process to S507.

  When the result of S505 is Yes, the device associating unit 202 shifts the process to S506.

  In step S <b> 506, the device association unit 202 associates the selected real device with another customer facility that is the association request source, and stores association information indicating the association in the secondary storage device 105. Here, the registration consent confirmation of the customer is configured to obtain the customer's input each time. For example, if the customer has previously agreed to link with other customer facilities, etc. This input operation becomes unnecessary.

  In step S <b> 507, the device association unit 202 determines whether the processing in step S <b> 502 has been performed for all real devices.

  If the result of S507 is No, the device associating unit 202 shifts the process to S502.

  If the result of S507 is Yes, the device association unit 202 ends this flow.

  The above is the flow of the linking process.

  If the actual equipment classification of the customer's equipment matches the actual equipment classification shown in the pegging request from the other customer facility, and the user's consent is obtained, the customer's equipment and other demand By associating the home facility, it is possible to select and associate other customer facilities necessary for the operation of the self-consumer equipment. Thereby, in the selection of the consumer facility 130 that maintains the power supply, it is possible to reflect the dependence of the user on the other consumer facility and the user's intention.

  FIG. 9 shows the linking information in the first embodiment. The association information has an entry for each real device. The entry of a certain real device includes the ID of the real device, the name of the real device, and a link destination that is a virtual device linked to the real device. In this example, the vehicle that is the linking request destination classification in the linking request matches the vehicle that is the actual device classification in the device information, and the oil stove that is the linking request destination classification in the linking request The case where the oil stove which is the real equipment classification in the equipment information matches is shown. As a result, the vehicle MC that is a real device is linked to the gas station GS that is a virtual device, and the oil stove ST that is a real device is linked to the gas station GS that is a virtual device. In addition, the refrigerator RF that is a real device is linked to the supermarket SM and the fish store FS that are virtual devices.

  Further, through this linking process, the consumer demand management apparatus 100 can specify another customer facility related to the own consumer device.

  Note that the consumer demand management apparatus 100 may perform a process that combines the virtual device registration process and the association process. That is, the consumer demand management apparatus 100 may link the own consumer device with another customer facility when registering a virtual device.

  Moreover, the consumer demand management apparatus 100 may transmit the pegging request including the customer facility classification of the customer facility 130 necessary for the operation of the own consumer device to other customer facilities. In this case, the consumer demand management device 100 may identify a transmission destination from the usage history of the own consumer device, and may transmit a linking request to the transmission destination, or a plurality of consumers in the community by multicast. The association request may be transmitted to the demand management apparatus 100. The customer demand management apparatus 100 of the other customer facility that has received the association request has the customer facility classification of the other customer facility and the customer facility classification of the customer facility 130 indicated in the association request. If they match, the linking agreement may be transmitted to the linking request source. When receiving the consent, the consumer demand management device 100 that is the transmission source of the association request registers the agreed other consumer facility as a virtual device, and associates the own consumer device with the virtual device.

  Here, it returns to description of the flow of customer facility management processing.

  In step S <b> 303, the device usage amount monitoring unit 203 records device usage amount information indicating the usage amount of the actual device in the secondary storage device 105. The device usage monitoring unit 203 may acquire a usage history from a connected consumer device and generate device usage information based on the usage history. The usage history of the consumer device may be created by the consumer device, may be created by a device that cooperates with the consumer device, or is connected to the consumer device. It may be created by the device usage monitoring unit 203 of the consumer demand management apparatus 100. In addition, the device usage monitoring unit 203 acquires the usage history of the unconnected consumer device based on the input from the user of the consumer demand management apparatus 100, and generates device usage information based on the usage history. May be. The usage history of the consumer device may indicate the use start time and the use end time, may indicate the number of times of use, and other customer facilities used for the operation of the consumer device May be shown.

  FIG. 10 shows device usage information in the first embodiment. The device usage information may be the actual device usage time, the actual device on / off count, and the like. The device usage information here includes device operating time (h / day) that is the operating time of the actual device in the past 24 hours. The device usage information includes a normalized device operating time that is a value obtained by normalizing the device operating time by the average device operating time of each real device classification in the community. The device usage information may not include the device virtual time and the average device operating time.

  For example, the community demand management device 110 collects device operation time from each customer facility 130, calculates an average value for each real device classification, and sets the average device operation time as the average device operation time. Notify device 100. In response to this, the consumer demand management device 100 stores the notified average device operating time in the device usage information in the secondary storage device 105. The average device operating time may be input to the consumer demand management device 100 in advance. Instead of the average equipment operating time, a reference usage amount such as an average value of usage frequency may be used. The device usage monitoring unit 203 divides the device operating time of each real device by the average device operating time to obtain a normalized device operating time.

  In this example, the device operating time of the car MC is 2.00 hours, and the average device operating time of the car MC is 1.20 hours. Therefore, the normalized device operating time of the car MC is (average device operating time) / (normalized device operating time) = 1.60. When the usage amount of the real device belonging to a certain real device class is larger than the average use amount of the real device class, the normalized device operating time of the real device becomes greater than 1, and the average use of the real device class If the amount is less than the amount, the normalized device operating time of the actual device is less than 1. In other words, the normalized device operating time represents 1 as the average usage amount in the community regardless of the actual device classification.

  When the real device is a refrigerator and the refrigerator detects opening / closing of the door, the device usage amount information may indicate the number of times the door is opened and closed, the frequency, and the like. When the real device is a car, the consumer demand management device 100 may receive a travel history or the like by communication with a car navigation device or a mobile terminal device mounted on the car. In this case, the device usage amount information may indicate travel history, position information, travel distance, use frequency, use time, and the like. When the actual device is a pump such as a water pump or a kerosene pump, the device usage amount information may indicate the number of times, the frequency, etc., of those pumps.

  In step S <b> 304, the device priority determination unit 204 determines device priority information indicating the device priority, and performs device priority determination processing to be stored in the secondary storage device 105. The device here is either a real device or a virtual device. The device priority information includes device priority. The device priority includes a real device priority that is a priority of the real device. When a virtual device is registered, the device priority information includes a virtual device priority that is a priority of the virtual device. For example, the device priority determination unit 204 periodically executes device priority determination processing at a frequency of once every 30 minutes, and updates the device priority information. The initial value of the virtual device priority until the device priority determination process is performed is zero.

  The above is the flow of customer facility management processing.

  Details of the device priority determination process in S304 will be described below.

  FIG. 11 shows device priority determination processing. The device priority determination unit 204 periodically executes priority update processing. Note that the device priority determination unit 204 has received a notification indicating that the status of the real device has changed, such as when a new real device is connected to the customer demand management apparatus 100 or when the real device has failed. In this case, device priority determination processing may be performed.

  In S600, the device priority determination unit 204 selects one real device that has not been selected from the real devices as a target real device, and determines whether the target real device has failed. This failure may include a case where the target real device connected to the consumer demand management apparatus 100 is disconnected from the consumer demand management apparatus 100 and is no longer managed by the consumer demand management apparatus 100. For example, the target real device transmits a survival signal to the consumer demand management apparatus 100 every predetermined period. In this case, the device failure detection unit 206 determines that the target real device has failed when the survival signal cannot be received during the predetermined period, and notifies the device priority determination unit 204 of the failure.

  When the result of S600 is No, the device priority determination unit 204 causes the process to proceed to S601. That is, the target real device is registered in the consumer demand management device 100 and is managed by the consumer demand management device 100.

  In step S <b> 601, the device priority determination unit 204 calculates the real device priority of the target real device based on the device usage information of the target real device stored in the secondary storage device 105. The actual device priority in the device 105 is rewritten to the calculation result. The real device priority is, for example, a value obtained by multiplying the normalized device operating time of a certain real device by the real device weight coefficient of the real device. The real device weighting factor is, for example, a weighting factor set in advance for each real device classification. The user of the consumer demand management apparatus 100 sets the actual device weight coefficient set in the actual device classification for which the real device priority is to be increased higher than the actual device weight coefficient set in the other actual device classification, The possibility that a real device of a specific real device classification becomes effective can be increased.

  In step S <b> 602, the device priority determination unit 204 reads the association information of the target real device from the secondary storage device 105.

  In step S <b> 603, the device priority determination unit 204 sets the virtual device linked to the target real device as the target virtual device, and calculates the increase due to the subscription of the target real device with respect to the virtual device priority of the target virtual device. To do. Here, the device priority determination unit 204 calculates the virtual device priority of the target virtual device using the real device priority of the target real device stored in the secondary storage device 105. The virtual device priority is, for example, a sum of values obtained by multiplying the real device priority of all the real devices linked to the target virtual device by the virtual device weight coefficient of the target virtual device. The virtual device weight coefficient is, for example, a weight coefficient set in advance for each customer facility classification. Therefore, the increment is, for example, a value obtained by multiplying the real device priority of the subscribed real device by the weight coefficient of the virtual device. The user of the consumer demand management apparatus 100 sets the virtual device weighting factor set for the customer facility classification whose virtual device priority is desired to be higher than the virtual device weighting factor set for the other consumer facility classifications. By this, it is possible to increase the possibility that other customer facilities operate in a specific customer facility classification.

  In step S <b> 604, the device priority determination unit 204 adds the increment to the virtual device priority in the device priority information in the secondary storage device 105, and sets the virtual device priority in the secondary storage device 105. Rewrite the calculation result.

  In step S <b> 605, the device priority determination unit 204 determines whether the processing in step S <b> 600 has been performed for all real devices.

  When the result of S605 is No, the device priority determination unit 204 causes the process to proceed to S602.

  If the result of S605 is Yes, the device priority determination unit 204 ends this flow.

  When the result of S600 is Yes, the device priority determination unit 204 causes the process to proceed to S606. That is, it is a case where it is determined that the target real device is out of order.

  In step S <b> 606, the device priority determination unit 204 calculates the real device priority of the target real device based on the device usage information of the target real device, and sets the real device priority in the secondary storage device 105. Rewrite the calculation result. Here, the real device priority of the target real device is, for example, 0. This is because it is generally considered that power supply to a failed real device is useless.

  In step S <b> 607, the device priority determination unit 204 reads the association information of the target real device from the secondary storage device 105.

  In step S <b> 608, the device priority determination unit 204 sets the virtual device linked to the target real device as the target virtual device, and calculates a decrease due to the detachment of the target real device with respect to the virtual device priority of the target virtual device. To do. This decrease is, for example, a value obtained by multiplying the real device priority of the target real device that has failed by the weight coefficient of the target virtual device.

  In step S <b> 609, the device priority determination unit 204 subtracts the decrease from the virtual device priority in the device priority information in the secondary storage device 105, and sets the virtual device priority in the secondary storage device 105. The process is updated, and the process proceeds to S605 described above.

  The above is the flow of the device priority determination process.

  FIG. 12 shows device priority information in the first embodiment. The device priority information has an entry for each device. The entry of a certain device includes an ID of the device, a name of the device, a device classification of the device, a real device weight coefficient CA set in the real device classification of the device, and a customer facility classification of the device. Virtual device weighting coefficient CB set to, and the device priority of the device. The device priority is a real device priority or a virtual device priority. The real device priority is obtained by CA × (normalized device operating time). In this example, the normalized equipment operating time of the car MC is 1.60, the normalized equipment operating time of the oil stove ST is 0.33, and the real equipment weight coefficient CA for the car MC, the oil stove ST, and the refrigerator RF is 10 Suppose that At this time, the real device priority of the vehicle MC is 16, and the real device priority of the oil stove ST is 3.3.

  Also, the virtual device priority is obtained from the sum of (CB × real device priority of the real device linked to the virtual device). In this example, it is assumed that the gas station GS is linked to the car MC and the oil stove ST, and the virtual device weight coefficient CB set to the gas station is 5. At this time, the virtual device priority of the gas station GS is CA × (real device priority of car MC) + CB × (real device priority of oil stove ST) = 5 × 16 + 5 × 3.3 = 96.5 .

  Hereinafter, processing by the community demand management apparatus 110 will be described.

  The community demand management apparatus 110 performs registration of the customer facility 130 to the community, determination of priority of the customer facility 130, detection of community power tightness, request for power saving / power outage to the customer facility 130, and the like.

  The customer registration unit 210 registers the customer facility 130 in the community. Here, when a new customer demand management device 100 is connected to the community demand management device 110 via the communication network 120, the customer registration unit 210 displays customer facility information indicating the customer demand management device 100. Register in the secondary storage device 115. At this time, the consumer registration unit 210 recognizes the customer name that is the name and identifier of the connected consumer demand management apparatus 100. For example, the administrator of the community demand management device 110 may input a customer name via the input / output unit 113, or the customer demand management device 100 or the customer registration unit 210 determines the customer name in advance. The customer name may be determined according to this database.

  The consumer priority determination unit 211 performs a consumer priority determination process for determining a customer priority that is a priority of a consumer. Here, the consumer priority determination unit 211 acquires the virtual device priority information of the consumer demand management apparatus 100 via the communication network 120, determines the consumer priority that is the priority of the consumer, The customer priority information in the next storage device 115 is updated. The consumer priority information includes consumer priorities of a plurality of consumers. Here, the consumer priority determination unit 211 may transmit a request for virtual device priority to the consumer demand management apparatus 100. In this case, in response to the request for virtual device priority, the communication unit 102 of the consumer demand management device 100 transmits the virtual device priority to the community demand management device 110, and the communication unit 112 of the community demand management device 110 This virtual device priority is received.

  Details of the consumer priority determination process will be described below.

  FIG. 13 shows a consumer priority determination process. For example, the customer priority determination process is periodically executed at a frequency of once per hour to update the customer priority information.

  In S <b> 700, the customer priority determination unit 211 receives virtual device priority from the consumer demand management devices 100 of all customer facilities 130 managed by the community demand management device 110. Here, the consumer demand management apparatus 100 may transmit all of the device information, or may transmit only the virtual device entry in the device information. Also, the device information may be divided into real device information and virtual device information.

  Next, in S710, the customer priority determination unit 211 selects one unselected customer facility 130 from all the customer facilities 130 as a target consumer facility.

  Next, in S711, the consumer priority determination unit 211 determines the consumer priority of the target consumer facility based on the acquired virtual device priority. Here, for example, the customer priority determination unit 211 sets a sum of values obtained by multiplying a plurality of virtual device priorities corresponding to the target customer facility by the customer facility weight coefficient as the customer priority of the target customer facility. . The customer facility weighting factor is a weighting factor set in advance for each customer facility classification. The administrator of the community demand management device 110 sets the customer facility weight coefficient set in the customer facility classification for which the customer priority is to be increased higher than the customer facility weight coefficient set in the other customer facility classification. By doing, the possibility that the customer facility 130 of a specific customer facility classification will operate can be increased. According to this consumer priority calculation method, virtual device priorities collected from a plurality of consumer facilities 130 are reflected in the consumer priorities of the corresponding customer facilities 130. The method for calculating the customer priority is not limited to this example.

  In step S <b> 712, the customer priority determination unit 211 stores the calculation result of the customer priority in the secondary storage device 115.

  Next, in S713, the customer priority determination part 211 determines whether the process of S710 was performed about all the customer facilities 130. FIG.

  When the result of S713 is No, the customer priority determination unit 211 shifts the process to S710.

  When the result of S713 is Yes, the customer priority determination unit 211 ends this flow.

  The above is the flow of the consumer priority determination process.

  FIG. 14 shows customer priority information in the first embodiment. The customer priority information has an entry for each customer facility 130 in the community. The entry of a certain customer facility 130 includes the ID of the customer facility 130, the name of the customer facility 130, the customer facility weight coefficient CC of the customer facility 130, and the customer priority of the customer facility 130. Including. The name of the customer facility 130 may indicate the name of the customer corresponding to the customer facility 130. For example, when the customer facility classification is a general household, since the possibility of being registered as a virtual device by another customer facility is low, the customer priority is lower than that of the other customer facility 130 or 0.

  The power tightness detection unit 212 detects when the power demand in the community is likely to exceed the power supply. The power tightness detection unit 212 receives, for example, power supply information and power demand information of each customer facility 130 in the community from the consumer demand management device 100 via the communication network 120, and an entity outside the community such as an electric power company. Receives power supply information and power demand information. Next, the power tightness detection unit 212 calculates the sum of the power demand amount of each customer facility 130 in the community and the power demand amount for a subject outside the community as the total power demand amount, and all the demands in the community are calculated. The sum of the power supply amount of the house facility 130 and the sum of the power supply amounts for the subjects outside the community are calculated as the total power supply amount. Next, when the value obtained by subtracting the total power demand from the total power demand is below a certain value, the power tightness detection unit 212 determines that the power in the community is tight.

  The priority request unit 213 selects a consumer who preferentially issues a power consumption reduction request when a community power tightness is detected, and sends a power consumption reduction request to the selected consumer. The power consumption reduction request is a power saving request or a power outage request.

  Here, when power tightness is detected by the power tightness detection unit 212, the priority requesting unit 213 acquires the customer priority from the secondary storage device 115 and corresponds to the customer priority satisfying the customer priority condition. A power consumption reduction request is transmitted to the consumer demand management apparatus 100 of the consumer facility 130. For example, the priority request unit 213 transmits a power consumption reduction request to the customer demand management apparatus 100 of the customer facility 130 whose customer priority is equal to or lower than a preset priority threshold. Further, the priority request unit 213 calculates a power consumption reduction amount necessary for resolving the power tightness based on the total power demand amount and the total power demand amount, and consumes the consumer facilities in order from the customer facility 130 with the lower customer priority. The customer facility 130 may be selected until the power reduction amount is satisfied, and a power consumption reduction request may be transmitted to the selected customer facility 130. According to such a method for transmitting a power consumption reduction request, it is possible to transmit a power consumption reduction request preferentially to a customer facility 130 whose consumer priority is lower than that of other customer facilities 130. Note that the method of transmitting the power consumption reduction request is not limited to this embodiment.

  For example, when the customer demand management device 100 of many customer facilities 130 in the community registers the gas station GS as a virtual device, when there are many cars and oil stoves linked to the gas station GS in the community, If there is a large amount of vehicles or oil stoves that are linked to the gas station GS, the customer priority of the gas station GS will increase, and the power supply to the gas station GS may be maintained when power is tight Becomes higher.

  Further, the self-consumer device may be associated with another customer facility that supplies resources necessary for its use. For example, when the self-consumer device is a car, the resource is gasoline, and the other consumer facility that supplies the resource is a gas station. In addition, for example, when the own consumer device is an oil stove, the resource is kerosene, and the other consumer facility that supplies the resource is a gas station. Further, for example, when the self-consumer device is a refrigerator, the resource is a food product, and the other consumer facility that supplies the resource is a supermarket.

  When the consumer device 106 includes a distributed power supply, the consumer demand management apparatus 100 that has received a power consumption reduction request can reduce the power consumption of the customer facility 130 using the distributed power supply.

  According to the conventional technology, it is difficult to measure the usage frequency of other customer facilities by the customer. On the other hand, according to the present embodiment, the consumer priority of the consumer facility 130 is determined based on a value indicating the usage rate of the consumer device 106 in another consumer facility 130 related to the consumer facility 130. To do. The actual device priority of the customer device 106 is related to the customer priority of other customer facilities in the community. For example, if a gas station stops functioning, the gasoline car will not be able to receive the supply of gasoline, and its function will stop, so there is a relationship between the actual equipment priority of the gasoline car and the customer priority of the gas station. It can be said that there is. This is because a gas station that is another customer facility is indirectly used by a customer via a gasoline vehicle that is a self-customer device.

  According to the present embodiment, virtual device priorities are obtained from a plurality of customer facilities 130 in the area and aggregated, so that the priority of each customer facility 130 in the area can be set as the lifestyle of many consumers. It can be decided according to. Thereby, for example, when performing a peak shift of power demand, it is possible to prevent a power outage of a customer facility 130 that is used by a large number of customers in accordance with the occasion, and to the daily life of consumers in the community. The impact can be minimized. Further, since the consumer demand management apparatus 100 does not need to calculate the priority of virtual devices other than the consumer facility 130 having high relevance to itself in the community, the calculation load of the consumer demand management apparatus 100 is reduced. Can do. Moreover, the priority of the facility relevant to the apparatus which a consumer uses every day can be increased, and it can prevent that the facility utilized for many consumers stops functioning by electric power suppression. In other words, the facility where the power supply is maintained can be determined by the consensus of consumers in the region. Specifically, as the usage amount of the customer device increases, the possibility that the power supply to other customer facilities associated with the customer device is maintained increases.

  A present Example demonstrates the case where the customer facility 130 in the electric power supply-demand adjustment system of Example 1 is a factory or its related facility.

  The power supply and demand adjustment system of the present embodiment has the same configuration as the power supply and demand adjustment system of the first embodiment.

This device information is obtained by adding virtual device information to real device information. This virtual device information uses the distribution center LC, which is another customer facility, as a virtual device.

  In S400 of the virtual device registration process, the method in which the device registration unit 201 recognizes the customer demand management device 100 of another customer facility may be different from that in the first embodiment. As a method for recognizing other customer facilities, that is, other factories, for example, when making a contract for energy supply with another factory, the device registration unit 201 may recognize the consumer demand management device 100 of the factories. .

According to this device priority information, CA is 10 and CB is 5. The real device priority of the car MC is CA × (normalized device operating time of the car MC) = 10 × 1.60 = 16. Moreover, the real equipment priority of the food FA processing machine PA is CA × (normalized equipment operating time of the food FA processing machine PA) = 10 × 0.33 = 3.3. In addition, since the distribution center LC is linked to the vehicle MC and the food FA processing machine PA, the virtual device priority of the distribution center LC is CB × (actual device priority of the vehicle MC) + CB × (food FA Real device priority of processing machine PA) = 5 × 16 + 5 × 3.3 = 96.5.

  Registration of the consumer facility 130 to the community, determination of consumer priority, detection of community power tightness, and power saving / power failure request to the consumer facility 130 by the community demand management device 110 are the same as in the first embodiment. .

When it is necessary to block some roads in the event of power shortages or disasters, the community demand management device 110 acquires the virtual device priority from all the consumer demand management devices 100, and sets it as the virtual device priority. Based on this, the priority of the road is calculated. Next, the community demand management device 110 selects a road to be blocked based on the priority of the road.
