[0010] FIG. 1 is a schematic diagram of an example of an electric power supply and demand adjustment system 1 according to this embodiment.

[0011] The power supply and demand adjustment system 1 includes an RA (resource aggregator) server 10, an AC (aggregation coordinator) server 20, a grid operator server 30, a trading market server 40, and a monitoring server 50. The RA server 10, the AC server 20, the grid operator server 30, the trading market server 40, and the monitoring server 50 are connected to each other so as to be able to communicate with each other via a network NW or the like.

[0012] The RA server 10 is an information processing device provided in the resource aggregator 2 .

[0013] The resource aggregator 2 is a business operator that directly concludes a VPP (Virtual Power Plant) service contract with one or more power supply and demand facilities 3 and controls the amount of power. In this embodiment, it is assumed that the power supply and demand adjustment system 1 includes multiple RA servers 10, and each of the multiple resource aggregators 2 uses a different RA server 10. Each of the multiple RA servers 10 included in the power supply and demand adjustment system 1 is communicatively connected to a different power supply and demand facility 3 and manages the connected power supply and demand facility 3. In other words, the power supply and demand facility 3 communicatively connected to the RA server 10 is managed by the RA server 10 and the resource aggregator 2 that uses the RA server 10. The RA server 10 functions as a home energy management system (HEMS), a distributed energy resource management system (DERMS), a building energy management system (BEMS), or the like, depending on the type of connected power supply and demand facility 3, the installation environment, and the like.

[0014] In this embodiment, the RA server 10 of the resource aggregator 2 causes the power supply and demand facilities 3 under management to adjust the amount of power supply and demand and execute a demand response, based on power supply and demand adjustment request information, which is a request for adjusting the amount of power supply and demand, from the system operator server 30 of the system operator 6. The power supply and demand adjustment request information is sometimes referred to as a demand response event. The power supply and demand adjustment request information will be described in detail later.

[0015] The power supply and demand facility 3 is an entity that supplies and demands power to and from the power grid 4. In particular, the power supply and demand facility 3 is composed of one or more devices, and these devices are capable of at least one of supplying power to and demanding power from the power grid 4. Devices that demand power are sometimes referred to as consumers. The power supply and demand facility 3 itself is sometimes referred to as a consumer. The power supply and demand facility 3 is connected to the power grid 4 so as to be able to supply and demand power. Examples of devices that make up the power supply and demand facility 3 include storage batteries, photovoltaics (PV), fuel cells, air conditioners, eco-cutes, electric vehicles (EVs), equipment installed in factories, equipment installed in homes, equipment installed in buildings, etc.

[0016] The AC server 20 is an information processing device provided in the aggregation coordinator 5. The AC server 20 is an example of an electric power supply and demand adjusting device.

[0017] The aggregation coordinator 5 is a coordinator that aggregates the power of the power supply and demand facilities 3 managed by each of the multiple resource aggregators 2 for each resource aggregator 2 and trades power with the grid operator 6. Being managed by the resource aggregator 2 means being managed by the RA server 10 of the resource aggregator 2.

[0018] The grid operator server 30 is an information processing device provided in the grid operator 6. The grid operator 6 is an electric power company, an electricity transmission and distribution business operator, or the like.

[0019] The market server 40 is an information processing device provided in the market 7. The market 7 is a market for trading electricity.

[0020] The monitoring server 50 is an information processing device that monitors communication data communicated within the power supply and demand adjustment system 1 .

[0021] Next, the functional configurations of the RA server 10, the grid operator server 30, the market trading server 40, the monitoring server 50, and the AC server 20 will be described.

[0022] FIG. 2 is a block diagram showing an example of the functional configuration of the RA server 10. As shown in FIG.

[0023] The RA server 10 includes a communication unit 12, a UI (user interface) unit 14, a storage unit 16, and a processing unit 18. The communication unit 12, the UI unit 14, the storage unit 16, and the processing unit 18 are connected to each other so as to be able to communicate with each other via a bus or the like.

[0025] The UI unit 14 and the storage unit 16 may be configured to be communicably connected to the processing unit 18 via a wired or wireless connection. At least one of the UI unit 14 and the storage unit 16 may be configured to be provided outside the RA server 10, and at least one of the UI unit 14 and the storage unit 16 may be connected to the processing unit 18 via a network NW or the like.

[0026] Processing unit 18 executes information processing in RA server 10. Processing unit 18 executes a program in a processor such as a CPU (Central Processing Unit), that is, executes information processing using software.

[0027] FIG. 3 is a block diagram showing an example of the functional configuration of the grid operator server 30.

[0028] The grid operator server 30 includes a communication unit 32, a UI unit 34, a storage unit 36, and a processing unit 38. The communication unit 32, the UI unit 34, the storage unit 36, and the processing unit 38 are connected to each other so as to be able to communicate with each other via a bus or the like.

[0029] The communication unit 32 is a communication function unit for communicating with various devices and information processing devices. The UI unit 34 has a display function and an input function. The display function and the input function are the same as those described above.

[0030] The UI unit 34 and the storage unit 36 ​​may be configured to be communicably connected to the processing unit 38 via a wired or wireless connection. At least one of the UI unit 34 and the storage unit 36 ​​may be configured to be provided outside the grid operator server 30, and at least one of the UI unit 34 and the storage unit 36 ​​may be connected to the processing unit 38 via a network NW or the like.

[0031] The processing unit 38 executes information processing in the system operator server 30. The processing unit 38 executes the information processing by causing a processor such as a CPU to execute a program, that is, by software.

[0032] FIG. 4 is a block diagram showing an example of the functional configuration of the market trading server 40.

[0033] The market trading server 40 includes a communication unit 42, a UI unit 44, a storage unit 46, and a processing unit 48. The communication unit 42, the UI unit 44, the storage unit 46, and the processing unit 48 are communicatively connected via a bus or the like.

[0034] The communication unit 42 is a communication function unit for communicating with various devices and information processing devices. The UI unit 44 has a display function and an input function. The display function and the input function are the same as those described above.

[0035] The UI unit 44 and the storage unit 46 may be configured to be communicably connected to the processing unit 48 via a wired or wireless connection. At least one of the UI unit 44 and the storage unit 46 may be configured to be provided outside the market trading server 40, and at least one of the UI unit 44 and the storage unit 46 may be connected to the processing unit 48 via a network NW or the like.

[0036] The processing unit 48 executes information processing in the market trading server 40. The processing unit 48 executes the information processing by causing a processor such as a CPU to execute a program, that is, by using software.

[0037] In this embodiment, the storage unit 46 stores a remuneration management DB (database) 46A and a capacity management DB 46B.

[0038] FIG. 5A is a schematic diagram showing an example of the data configuration of the remuneration management DB 46A.

[0039] The remuneration management DB 46A is a database for managing remuneration management information. The data structure of the remuneration management DB 46A is not limited to a database.

[0040] The reward management information is information that specifies reward information for each adjustment time, with higher rewards being awarded the shorter the adjustment time. For example, the reward management information is information that associates adjustment times, levels, and reward multipliers.

[0041] The adjustment time is the time required for the power supply and demand facility 3 to adjust power to a predetermined adjustment power amount. More specifically, the adjustment time is the time required for the devices constituting the power supply and demand facility 3 to adjust power to a predetermined adjustment power amount. The predetermined adjustment power amount is the amount of power that the power supply and demand facility 3 can reduce or supply from the baseline. The baseline is the predicted amount of power supply and demand of the power supply and demand facility 3. The baseline may also be the amount of power supply and demand of the power supply and demand facility 3 when no adjustment of power supply and demand is performed by demand response.

[0042] The level indicates the power adjustment capability, and the shorter the adjustment time, the higher the level. In this embodiment, the larger the numerical value, the higher the level.

[0043] The reward multiplier is an example of reward information related to rewards. Reward management information is set with reward information that indicates a higher reward the shorter the adjustment time. The reward multiplier represents a multiplier relative to a preset standard reward. Note that reward information related to rewards may also include reward amounts, reward points, etc. Reward points are electronic reward information used in specific systems, etc.

[0044] The remuneration management information may be information that specifies remuneration information for each adjustment time, with higher remuneration the shorter the adjustment time, and may be one type of information that is common within the power supply and demand adjustment system 1, or may be information specified for each grid operator 6. In this embodiment, a form in which the remuneration management information is information specified for each grid operator 6 will be described as an example.

[0045] For this reason, in this embodiment, a form will be described in which the remuneration management DB 46A is a database in which a system operator ID (Identification) is associated with remuneration management information. The system operator ID is identification information of the system operator 6.

[0046] For example, a user of the grid operator 6 inputs remuneration management information that specifies desired remuneration information by operating the UI unit 34 of the grid operator server 30. The processing unit 38 of the grid operator server 30 transmits the received remuneration management information and the grid operator ID of the grid operator 6 to the trading market server 40.

[0047] Every time the processing unit 48 of the trading market server 40 receives remuneration management information from the system operator server 30 of the system operator 6, the processing unit 48 associates the received remuneration management information with the system operator ID of the system operator 6 that uses the system operator server 30 that is the sender of the remuneration management information, and registers the information in the remuneration management DB 46A. Therefore, the remuneration management information set by the system operator 6 is registered for each system operator 6 in the remuneration management DB 46A.

[0048] In addition, when one type of remuneration management information is used commonly within the electricity supply and demand adjustment system 1, the processing unit 48 of the trading market server 40 simply stores the remuneration management information input by operating instructions on the UI unit 44, etc., in the memory unit 46 as remuneration management information to be used commonly within the electricity supply and demand adjustment system 1.

[0049] In this embodiment, the processing unit 48 of the trading market server 40 manages the remuneration management DB 46A so that it is accessible to each of the information processing devices included in the electricity supply and demand adjustment system 1. Therefore, the latest state of the remuneration management DB 46A is made publicly available to and managed by the information processing devices in the electricity supply and demand adjustment system 1.

[0050] FIG. 5B is a schematic diagram showing an example of the data configuration of the capability management DB 46B.

[0051] The capability management DB 46B is a database for managing capability management information. The data structure of the capability management DB 46B is not limited to a database.

[0052] The capacity management information is information that specifies at least the adjustment time required for adjusting the power to a predetermined adjustment power amount for each of one or more power supply and demand facilities 3 that are managed by the resource aggregator 2. The power supply and demand facilities 3 that are managed by the resource aggregator 2 refer to the power supply and demand facilities 3 that are managed by the RA server 10 of the resource aggregator 2.

[0053] Specifically, for example, the capacity management information is information that associates an adjustment time, a device name, and an amount of power to be adjusted.

[0054] As described above, the adjustment time is the time required for the power supply and demand facility 3 to adjust power to the predetermined adjustment power amount. In other words, the adjustment time is the time required from when the power supply and demand facility 3 starts power adjustment control until the corresponding adjustment power amount is reduced or supplied. The predetermined adjustment power amount is the amount of power that the power supply and demand facility 3 can reduce or supply from the baseline. The equipment name is an example of identification information for the equipment that constitutes the power supply and demand facility 3.

[0055] The capacity management DB 46B stores, for each resource aggregator 2, capacity management information that specifies the adjustment time for each of the power supply and demand facilities 3 managed by the resource aggregator 2. That is, the compensation management DB 46A is a database that associates RAID with capacity management information. The RAID is identification information of the resource aggregator 2.

[0056] For example, the RA server 10 of the resource aggregator 2 receives the adjustment time and the adjusted power amount of each of the devices constituting the power supply and demand facility 3 to be managed at predetermined intervals from the devices constituting the power supply and demand facility 3, and generates capacity management information that associates the adjustment time of each of the devices constituting the power supply and demand facility 3 to be managed, the device name which is identification information of the device constituting the power supply and demand facility 3, and the adjusted power amount. Then, the RA server 10 transmits the capacity management information and RAID to the trading market server 40 via the AC server 20 at predetermined intervals or each time the capacity management information is updated.

[0057] Every time the processing unit 48 of the market trading server 40 receives the RAID and capacity management information from the grid operator server 30, the processing unit 48 associates the received RAID with the capacity management information and registers them in the capacity management DB 46B. Therefore, the capacity management DB 46B registers, for each resource aggregator 2, capacity management information in which adjustment times are specified for each of the devices constituting the power supply and demand facility 3 that is the target of management by the RA server 10 of the resource aggregator 2.

[0058] In this embodiment, the processing unit 48 of the trading market server 40 manages the capacity management DB 46B so that it is accessible to the information processing devices included in the power supply and demand adjustment system 1. Therefore, the latest state of the capacity management DB 46B is made publicly available to and managed by the information processing devices included in the power supply and demand adjustment system 1.

[0059] FIG. 6 is a block diagram showing an example of the functional configuration of the monitoring server 50. As shown in FIG.

[0060] The monitoring server 50 includes a communication unit 52, a UI unit 54, a storage unit 56, and a processing unit 58. The communication unit 52, the UI unit 54, the storage unit 56, and the processing unit 58 are connected to each other so as to be able to communicate with each other via a bus or the like.

[0061] The communication unit 52 is a communication function unit for communicating with various devices and information processing devices. The UI unit 54 has a display function and an input function. The display function and input function are the same as those described above. The UI unit 54 and the storage unit 56 may be configured to be communicably connected to the processing unit 58 via a wired or wireless connection. At least one of the UI unit 54 and the storage unit 56 may be configured to be provided outside the monitoring server 50, and at least one of the UI unit 54 and the storage unit 56 may be connected to the processing unit 58 via a network NW or the like.

[0062] The processing unit 58 executes information processing in the monitoring server 50. The processing unit 58 executes the information processing by causing a processor such as a CPU to execute a program, that is, by software.

[0063] In this embodiment, the processing unit 58 monitors and detects abnormalities in communications within the power supply and demand adjusting system 1. The communication monitoring process performed by the monitoring server 50 will be described later.

[0064] FIG. 7 is a functional block diagram of an example of the functional configuration of the AC server 20. As shown in FIG.

[0065] The AC server 20 includes a communication unit 22, a UI unit 24, a storage unit 26, and a processing unit 28. The communication unit 22, the UI unit 24, the storage unit 26, and the processing unit 28 are connected to each other so as to be able to communicate with each other via a bus or the like.

[0066] The communication unit 22 is a communication function unit for communicating with various devices and information processing devices. The UI unit 24 has a display function and an input function. The display function and input function are the same as those described above. The storage unit 26 stores various types of information.

[0067] The UI unit 24 and the storage unit 26 may be configured to be communicably connected to the processing unit 28 via a wired or wireless connection. At least one of the UI unit 24 and the storage unit 26 may be configured to be provided outside the AC server 20, and at least one of the UI unit 24 and the storage unit 26 may be communicably connected to the processing unit 28 via a network NW or the like.

[0068] The processing unit 28 executes information processing in the AC server 20. The processing unit 28 includes a demand response (DR) contract processing unit 28A, a capacity management information updating unit 28B, a bidding processing unit 28C, a successful bid processing unit 28D, a selection unit 28E, a remuneration derivation unit 28F, and a monitoring unit 28G.

[0069] The DR contract processing unit 28A, the capacity management information update unit 28B, the bidding processing unit 28C, the successful bid processing unit 28D, the selection unit 28E, the remuneration derivation unit 28F, and the monitoring unit 28G are realized, for example, by one or more processors. For example, each of the above units may be realized by having a processor such as a CPU execute a program, i.e., by software. Each of the above units may be realized by a processor such as a dedicated IC, i.e., by hardware. Each of the above units may be realized by a combination of software and hardware. When multiple processors are used, each processor may realize one of the units, or two or more of the units. Furthermore, at least one of the above units may be provided in an external device communicatively connected to the processing unit 88.

[0070] The DR contract processing unit 28A executes processing to conclude a contract regarding a demand response that adjusts the balance between power supply and demand among the AC server 20 of the aggregation coordinator 5, the RA server 10 of the resource aggregator 2, and the system operator server 30 of the system operator 6.

[0071] In detail, for example, the DR contract processing unit 28A receives contract information related to a DR (demand response) contract from each RA server 10 of one or more resource aggregators 2, and upon receiving an instruction to conclude the contract information through a user's operation instruction on the UI unit 24 of the AC server 20, transmits contract conclusion information indicating the conclusion of the contract to the RA server 10 of the resource aggregator 2. Through these processes, a DR contract is concluded between the AC server 20 of the aggregation coordinator 5 and the RA server 10 of one or more resource aggregators 2.

[0072] Furthermore, for example, the DR contract processing unit 28A receives contract information related to the DR contract from the system operator server 30 of one or more system operators 6, and when it receives an instruction to conclude the contract information by a user's operation instruction on the UI unit 24 of the AC server 20, etc., it transmits contract conclusion information indicating the conclusion of the contract to the system operator server 30 of the system operator 6. Through these processes, a DR contract is concluded between the AC server 20 of the aggregation coordinator 5 and the system operator server 30 of one or more system operators 6.

[0073] The capacity management information update unit 28B updates the capacity management information of the power supply and demand facilities 3 that are managed by each RA server 10 of the resource aggregator 2 that has concluded a DR contract. In particular, the capacity management information update unit 28B receives capacity management information that specifies the RAID of the resource aggregator 2 and the adjustment time of each device that constitutes the power supply and demand facilities 3 that are managed by the RA server 10 of the resource aggregator 2, from each RA server 10 of multiple resource aggregators 2 that have concluded a DR contract with the AC server 20 of the aggregation coordinator 5 of the AC server 20 that includes the capacity management information update unit 28B. The capacity management information update unit 28B then associates the RAID and the capacity management information, stores them in the storage unit 26, and transmits them to the market trading server 40. As described above, the processing unit 48 of the market trading server 40 registers the received RAID and capacity management information in the capacity management DB 46B every time it receives the RAID and capacity management information from the AC server 20. Therefore, the updated capacity management DB 46B is managed so as to be open to the system operator server 30 and the AC server 20 .

[0074] The capacity management information update unit 28B may transmit the RAID and capacity management information received from the RA server 10 to the system operator server 30. In this case, the processing unit 38 of the system operator server 30 may store the received RAID and capacity management information in the storage unit 36 ​​in association with each other.

[0075] The bidding processing unit 28C executes bidding processing. In this embodiment, the bidding processing unit 28C transmits bidding information including the requested power adjustment amount of the resource aggregator 2 that can accommodate the requested power adjustment amount to the grid operator server 30 that is the source of the power bidding information, based on the power bidding information including the requested power adjustment amount and the capacity management information.

[0076] The power solicitation information is information transmitted by the system operator server 30 of the system operator 6 in order to secure in advance the amount of power supply and demand required by the system operator 6 through a public bidding. The power solicitation information includes, for example, the amount of solicited adjustment power, which is the amount of power supply and demand planned to be required by the system operator 6. The processing unit 38 of the system operator server 30 transmits the power solicitation information by transmitting it to the market trading server 40 in response to a user's operation instruction on the UI unit 34, etc. Alternatively, the processing unit 38 of the system operator server 30 may transmit the power solicitation information by transmitting it directly to the AC server 20. The bidding processing unit 28C of the AC server 20 may execute bidding processing when it receives the power solicitation information from the system operator server 30 or from the system operator server 30 via the market trading server 40.

[0077] The bidding processing unit 28C uses the capacity management information of each of the multiple resource aggregators 2 to calculate, for each resource aggregator 2, the total value of the adjustment amount of power for each device constituting the power supply and demand facility 3 included in the capacity management information. Then, the bidding processing unit 28C compares the total value of the adjustment amount of power for each of one or more resource aggregators 2 with the offered adjustment amount of power included in the power public bidding information, and determines whether or not adjustment of power supply and demand for the offered adjustment amount of power is possible by the power supply and demand facility 3 managed by the RA server 10 of the resource aggregator 2. If the bidding processing unit 28C determines that adjustment is possible, it transmits the bidding information to the grid operator server 30, which is the source of the power public bidding information, via the market trading server 40.

[0078] The bidding information includes, for example, the RAID of the resource aggregator 2 that can handle the power adjustment of the solicited adjustment power amount, and the biddable power amount that is the total value of the adjustment power amount of the resource aggregator 2. The bidding processing unit 28C may directly transmit the bidding information to the grid operator server 30 that is the source of the power public bidding information.

[0079] The processing unit 38 of the system operator server 30 identifies, from the capacity management DB 46B, capacity management information corresponding to each of one or more RAIDs included in the bidding information received from the AC server 20. The processing unit 38 also identifies, from the remuneration management DB 46A, remuneration management information corresponding to the system operator ID of the system operator 6 of the system operator server 30.

[0080] The processing unit 38 then identifies a combination of one or more resource aggregators 2 that can adjust the amount of requested adjustment power included in the transmitted power bidding information in an adjustment time less than the first threshold and with a remuneration less than the second threshold. The first and second thresholds may be set in advance. Furthermore, the first and second thresholds may be changeable as needed by a user operating the UI unit 34, for example. Furthermore, the processing unit 38 may arrange the multiple resource aggregators 2 in order of the ability to adjust the amount of requested adjustment power in a shorter adjustment time and with a smaller remuneration, and identify a predetermined number of resource aggregators 2 from the top. The processing unit 38 may perform the identification process based on the remuneration management DB 46A and the capacity management DB 46B.

[0081] Furthermore, the processing unit 38 allocates the successful bid power adjustment amounts to the identified one or more resource aggregators 2 based on the remuneration management DB 46A and the capacity management DB 46B so that the total value of the successful bid power adjustment amounts becomes the solicited adjustment power amount, and so that the adjustment time is shorter and the remuneration is lower. Then, the processing unit 38 of the grid operator server 30 transmits successful bid information including the RAIDs of the resource aggregators 2 and the successful bid power adjustment amounts allocated to each resource aggregator 2 identified by the RAID to the AC server 20.

[0082] The successful bid processing unit 28D of the AC server 20 executes the successful bid processing based on the successful bid information received from the grid operator server 30. The successful bid information includes at least the successful bid power adjustment amount. Based on the successful bid information, the successful bid processing unit 28D determines the resource aggregator 2 that has won the power bidding represented by the power bidding information transmitted from the grid operator server 30.

[0083] Specifically, assume that the successful bid processing unit 28D receives successful bid information including a RAID and a successful bid power adjustment amount for each resource aggregator 2 identified by the RAID. In this case, the successful bid processing unit 28D determines the resource aggregator 2 identified by the RAID included in the successful bid information as the resource aggregator 2 that has won the power bidding represented by the power bidding information. Then, the successful bid processing unit 28D associates a system operator ID that identifies the system operator 6 of the system operator server 30 that has transmitted the power bidding information, the RAID, and the successful bid power adjustment amount of the resource aggregator 2 identified by the RAID in the storage unit 26. Through this storage process, the storage unit 26 stores, for each system operator 6, the RAID and the successful bid power adjustment amount of the resource aggregator 2 that has won the power bidding transmitted by the system operator server 30 of the system operator 6, in association with each other.

[0084] The processing unit 38 of the grid operator server 30 may identify a combination of one or more aggregation coordinators 5 that can adjust the amount of solicited adjustment power included in the transmitted power bidding information in an adjustment time less than the first threshold and with a remuneration less than the second threshold. The processing unit 38 may also arrange the multiple aggregation coordinators 5 in order of their ability to adjust the amount of solicited adjustment power in a shorter adjustment time and with a smaller remuneration, and identify a predetermined number of aggregation coordinators 5 from the top. The processing unit 38 may perform these identification processes based on the remuneration management DB 46A and the capacity management DB 46B.

[0085] Furthermore, the processing unit 38 allocates the awarded power adjustment amounts to the identified one or more aggregation coordinators 5 so that the total value of the awarded power adjustment amounts becomes the solicited adjustment power amount, and the adjustment time and remuneration are shortened. The processing unit 38 may execute the allocation process based on the remuneration management DB 46A and the capacity management DB 46B. The processing unit 38 of the grid operator server 30 may then transmit, to the AC server 20 of the aggregation coordinator 5, winning bid information including the awarded power adjustment amounts allocated to the aggregation coordinator 5 of the AC server 20.

[0086] In this case as well, the successful bid processing unit 28D of the AC server 20 may execute the successful bid processing based on the successful bid information received from the grid operator server 30. That is, the successful bid processing unit 28D may determine, based on the successful bid information, the resource aggregator 2 that has made a successful bid for the power tender represented by the power tender information transmitted from the grid operator server 30.

[0087] In detail, in this case, the successful bid processing unit 28D receives successful bid information including the successful bid power adjustment amount allocated to the aggregation coordinator 5 of the AC server 20 having the successful bid processing unit 28D. In this case, based on the successful bid power adjustment amount included in the successful bid information, the remuneration management DB 46A, and the capacity management DB 46B, the successful bid processing unit 28D identifies one or more resource aggregators 2 from the multiple resource aggregators 2 managed by the AC server 20 of the aggregation coordinator 5 so that the total value of the adjustment power amounts becomes the successful bid adjustment power amount, and so that the adjustment time is shorter and the remuneration is lower. Then, the successful bid processing unit 28D determines the identified one or more resource aggregators 2 as the resource aggregators 2 that have won the power bidding represented by the power bidding information.

[0088] Furthermore, the successful bid processing unit 28D allocates the successful bid adjustment amount of power to the determined resource aggregator 2 so as to shorten the adjustment time and reduce the remuneration. The successful bid processing unit 28D may execute this allocation process based on the remuneration management DB 46A and the capacity management DB 46B. The successful bid processing unit 28D may then store in the storage unit 26 the RAID of the resource aggregator 2 and the successful bid power adjustment amount allocated to the resource aggregator 2 identified by the RAID in association with each other. Through this storage process, the storage unit 26 stores, for each grid operator 6, the RAID of the resource aggregator 2 that has won the power bidding issued by the grid operator 6 and the successful bid power adjustment amount in association with each other.

[0089] When the selection unit 28E receives power supply and demand adjustment request information from the system operator server 30 with which the DR contract has been concluded, the selection unit 28E selects a resource aggregator 2 that will execute power supply and demand adjustment in accordance with the power supply and demand adjustment information, based on the remuneration management information and the capacity management information. Selecting as the resource aggregator 2 that will execute power supply and demand adjustment means selecting as the resource aggregator 2 of the RA server 10 that will execute power supply and demand adjustment for the power supply and demand facilities 3 that are under management.

[0090] The power supply and demand adjustment request information is a request for adjustment of the amount of power supply and demand issued by the grid operator 6. The power supply and demand adjustment request information is sometimes referred to as a demand response event.

[0091] The power supply and demand adjustment request information includes a requested power amount and an adjustment period represented by an adjustment start time and an adjustment end time of the requested power amount. The adjustment power amount represents the amount of power to be reduced or supplied relative to a baseline.

[0092] The selection unit 28E selects one or more resource aggregators 2 that can adjust the requested amount of power supply and demand indicated in the power supply and demand adjustment request information received from the system operator server 30 with a remuneration less than a threshold by the adjustment start time indicated in the power supply and demand adjustment request information, as resource aggregators 2 that will perform power supply and demand adjustment in accordance with the power supply and demand adjustment request information.

[0093] In detail, the selection unit 28E selects one or more resource aggregators 2 that satisfy the conditions from among the resource aggregators 2 that have won the electricity tender represented by the electricity application information transmitted from the system operator server 30 that is the sender of the electricity supply and demand adjustment request information, as resource aggregators 2 that will perform electricity supply and demand adjustment in accordance with the electricity supply and demand adjustment request information, as determined by the successful bid processing unit 28D.

[0094] The condition indicates that the requested amount of power supply and demand indicated in the power supply and demand adjustment request information received from the system operator server 30 can be achieved with a remuneration less than a threshold by the adjustment start time indicated in the power supply and demand adjustment request information. The selection unit 28E may use remuneration management information corresponding to the system operator ID of the system operator 6 provided in the system operator server 30 and capacity management information corresponding to the RAID of the resource aggregator 2 determined by the successful bid processing unit 28D to select one or more resource aggregators 2 that satisfy the condition as resource aggregators 2 that will perform power supply and demand adjustment in accordance with the power supply and demand adjustment request information.

[0095] The selection process of the resource aggregator 2 by the selection unit 28E may be executed on the side of the grid operator server 30 that has transmitted the power supply and demand adjustment request information. In this case, the processing unit 38 of the grid operator server 30 executes the selection process in the same manner as the selection unit 28E, thereby selecting a resource aggregator 2 that will perform power supply and demand adjustment in accordance with the power supply and demand adjustment request information. Then, the processing unit 38 of the grid operator server 30 transmits the RAID of the selected resource aggregator 2 to the AC server 20. The AC server 20 selects the resource aggregator 2 identified by the RAID received from the grid operator server 30 as the resource aggregator 2 that will perform power supply and demand adjustment in accordance with the power supply and demand adjustment request information transmitted from the grid operator server 30.

[0096] The selection unit 28E may further determine the requested adjustment power amount for each resource aggregator 2 that performs the power supply and demand adjustment in accordance with the power supply and demand adjustment request information, based on the remuneration management information and the capacity management information, so that the power supply and demand adjustment can be performed in a shorter adjustment time and with less remuneration within the range of the successful bid power adjustment amount for the power public bidding information transmitted by the system operator server 30 of the system operator 6 that is the source of the power supply and demand adjustment request information.

[0097] The selection unit 28E obtains the successful bid power adjustment amount by reading the system operator ID of the system operator 6 that sent the power supply and demand adjustment request information, which are stored in the memory unit 26, and the successful bid power adjustment amount associated with the RAID of the resource aggregator 2 that won the power tender sent by the system operator 6, and uses the successful bid power adjustment amount in the determination process.

[0098] The process of determining the requested adjustment amount of power for each resource aggregator 2 may be executed by the grid operator server 30 of the grid operator 6 .

[0099] The selection unit 28E transmits DR instruction information including the requested adjustment power amount determined for the resource aggregator 2 to the RA server 10 of the resource aggregator 2 selected to perform power supply and demand adjustment.

[0100] The RA server 10 that has received the DR instruction information transmits DR execution instruction information to each of one or more power supply and demand facilities 3 that are to be managed, based on the DR instruction information.

[0101] For example, the processing unit 18 of the RA server 10 allocates the requested adjustment power amount included in the DR instruction information received from the AC server 20 so as to satisfy a predetermined condition based on the capacity management information of the power supply and demand equipment 3 managed by the RA server 10 and the remuneration management information associated with the system operator ID of the system operator 6 that has sent the power supply and demand adjustment request information. The predetermined condition indicates that power supply and demand adjustment can be achieved with a remuneration less than a predetermined threshold by the adjustment start time indicated in the power supply and demand adjustment request information. Note that this allocation process may be executed by either the system operator server 30 or the AC server 20.

[0102] Then, the processing unit 18 of the RA server 10 transmits DR instruction information including the requested adjustment amount of power allocated to each power supply and demand facility 3 and the adjustment period included in the power supply and demand adjustment request information to the devices constituting each power supply and demand facility 3 corresponding to the allocation. The devices constituting the power supply and demand facility 3 control the power supply and demand so that the adjustment period and power supply and demand amount included in the DR instruction information become the requested adjustment amount of power included in the DR instruction information. In other words, the devices constituting the power supply and demand facility 3 execute a demand response in accordance with the DR instruction information.

[0103] In addition, the RA server 10 of the resource aggregator 2 may control the equipment constituting each of the managed power supply and demand facilities 3 so that the equipment constituting each of the managed power supply and demand facilities 3 executes power supply and demand in accordance with the DR instruction information.

[0104] When the adjustment period included in the power supply and demand adjustment request information has elapsed, the processing unit 18 of the RA server 10 receives adjustment result information from the devices that make up the managed power supply and demand facility 3. The adjustment result information represents the amount of adjusted power that was actually adjusted by the devices that make up the power supply and demand facility 3 during the adjustment period. The processing unit 18 of the RA server 10 transmits the adjustment result information, including the total value of the amount of adjusted power received from the devices that make up the managed power supply and demand facility 3, to the AC server 20.

[0105] The remuneration derivation unit 28F of the AC server 20 receives adjustment result information of the power supply and demand adjustment in accordance with the power supply and demand adjustment request information from the RA server 10 of the resource aggregator 2. Then, the remuneration derivation unit 28F derives a claimed remuneration for each resource aggregator 2 based on the adjustment result information and the remuneration management information of the system operator server 30 that is the sender of the power supply and demand adjustment request information.

[0106] The remuneration derivation unit 28F reads, from the remuneration management DB 46A, remuneration management information corresponding to the system operator ID of the system operator 6 of the system operator server 30 that has transmitted the power supply and demand adjustment request information. Then, when the adjustment result information indicates an adjustment result in accordance with the power supply and demand adjustment request information, i.e., when the remuneration derivation unit 28F determines that the demand response has been successful, the remuneration derivation unit 28F derives a claimed remuneration for each resource aggregator 2 using the remuneration multiplier indicated in the read remuneration management information. Note that the derivation of the claimed remuneration by the remuneration derivation unit 28F may be executed by the system operator server 30. When the remuneration derivation unit 28F has derived the claimed remuneration, the remuneration derivation unit 28F transmits claimed remuneration information including the claimed remuneration to the system operator server 30 that has transmitted the power supply and demand adjustment request information.

[0107] The monitoring unit 28G monitors abnormalities in the communication data of the power supply and demand adjustment system 1. The monitoring unit 28G monitors abnormalities in various communication data communicated between the AC server 20, the grid operator server 30, the trading market server 40, and the devices constituting the power supply and demand facility 3, all of which are included in the power supply and demand adjustment system 1. A known method may be used for the abnormality monitoring method. Furthermore, the monitoring unit 28G may execute the same monitoring process as the monitoring server 50 described below (details will be described later). When the monitoring unit 28G detects an abnormality in the communication data, it outputs the abnormality detection result to at least one information processing device in the power supply and demand adjustment system 1.

[0108] Next, an example of the flow of information processing executed in the power supply and demand adjustment system 1 of this embodiment will be described.

[0109] FIG. 8 is a sequence diagram showing an example of the flow of information processing executed in the power supply and demand adjustment system 1 of this embodiment.

[0110] The DR contract processing unit 28A of the AC server 20 executes DR contract processing to conclude a contract regarding a demand response between the RA server 10 of the resource aggregator 2 and the grid operator server 30 of the grid operator 6 (steps S100 and S102).

[0111] The user of the system operator 6 operates the UI unit 34 of the system operator server 30 to input compensation management information that specifies desired compensation information. The processing unit 38 of the system operator server 30 transmits the received compensation management information and the system operator ID of the system operator 6 of the system operator server 30 to the market trading server 40 (step S104). Every time the processing unit 48 of the market trading server 40 receives compensation management information from the system operator server 30 of the system operator 6, the processing unit 48 associates the received compensation management information with the system operator ID of the system operator 6 of the system operator server 30 that sent the compensation management information, and registers the association in the compensation management DB 46A. Therefore, the compensation management information set by the system operator 6 for each system operator 6 is registered in the compensation management DB 46A. As described above, the market trading server 40 manages the compensation management DB 46A in a manner that allows it to be made publicly available to information processing devices within the power supply and demand adjusting system 1.

[0112] The RA server 10 of the resource aggregator 2 receives the adjustment time and the adjusted power amount of each device constituting the power supply and demand facility 3 to be managed from the device constituting the power supply and demand facility 3 at a predetermined timing, and generates capacity management information that associates the adjustment time, device name which is identification information of the device constituting the power supply and demand facility 3, and the adjusted power amount of each device constituting the power supply and demand facility 3 to be managed. Then, the RA server 10 transmits the capacity management information and the RAID of the resource aggregator 2 in which the RA server 10 is provided to the market server 40 via the AC server 20 (steps S106 and S108). Every time the processing unit 48 of the market server 40 receives the RAID and the capacity management information from the grid operator server 30, the processing unit 48 associates the received RAID with the capacity management information and registers it in the capacity management DB 46B. For this reason, the capacity management DB 46B registers, for each resource aggregator 2, capacity management information specifying the adjustment time for each of the devices constituting the power supply and demand facility 3 managed by the resource aggregator 2. As described above, the trading market server 40 manages the capacity management DB 46B in a manner that allows it to be made publicly available to information processing devices within the power supply and demand adjustment system 1.

[0113] When the grid operator server 30 transmits the power tender information (step S110), the market trading server 40 transmits the power tender information to the AC server 20 (step S112).

[0114] The bidding processing unit 28C of the AC server 20 executes bidding processing based on the received power solicitation information (step S114). For example, the bidding processing unit 28C of the AC server 20 generates bidding information including the bid-requested power adjustment amounts of the resource aggregators 2 that can correspond to the solicited adjustment power amount, based on the power solicitation information and capacity management information of each of one or more resource aggregators 2 managed by the aggregation coordinator 5 of the AC server 20. Then, the bidding processing unit 28C transmits the generated bidding information to the grid operator server 30 that is the source of the power solicitation information (step S116).

[0115] The processing unit 38 of the system operator server 30 executes a successful bid process based on the bidding information received from the AC server 20 (step S118). For example, the processing unit 38 of the system operator server 30 identifies, from the capacity management DB 46B, capacity management information corresponding to each of one or more RAIDs included in the bidding information. The processing unit 38 also identifies, from the remuneration management DB 46A, remuneration management information corresponding to the system operator ID of the system operator 6 of the system operator server 30.

[0116] The processing unit 38 then identifies a combination of one or more resource aggregators 2 that can adjust the solicited adjustment power amounts included in the transmitted power bidding information in an adjustment time less than the first threshold and with a remuneration less than the second threshold. Furthermore, the processing unit 38 allocates the awarded power adjustment amounts to the identified one or more resource aggregators 2, based on the remuneration management DB 46A and the capacity management DB 46B, so that the total value of the awarded power adjustment amounts becomes the solicited adjustment power amount, and so that the adjustment time is shorter and the remuneration is lower. The processing unit 38 of the grid operator server 30 then transmits winning bid information, including the RAIDs of the resource aggregators 2 and the awarded power adjustment amounts allocated to each resource aggregator 2 identified by the RAID, to the AC server 20 (step S120).

[0117] The successful bid processing unit 28D of the AC server 20 executes a successful bid process based on the successful bid information received from the grid operator server 30 (step S122). Specifically, the successful bid processing unit 28D of the AC server 20 determines, based on the successful bid information, the resource aggregator 2 that has won the power bidding represented by the power bidding information transmitted from the grid operator server 30. Then, the successful bid processing unit 28D associates a system operator ID that identifies the grid operator 6 of the grid operator server 30 that transmitted the power bidding information, the RAID of the determined resource aggregator 2, and the successful bid power adjustment amount of the resource aggregator 2 identified by the RAID, and stores these in the storage unit 26. Through this storage process, the storage unit 26 stores, for each grid operator 6, the RAID that identifies the resource aggregator 2 of the RA server 10 that has won the power bidding transmitted by the grid operator server 30 of the grid operator 6, and the successful bid power adjustment amount, in association with each other.

[0118] At least one of the bidding process (step S118) by the grid operator server 30 and the bidding process (step S122) by the AC server 20 may be executed by the processing unit 48 of the market trading server 40. As described above, at least a part of the bidding process (step S122) by the AC server 20 may be executed by the processing unit 38 of the grid operator server 30. At least a part of the bidding process (step S118) by the grid operator server 30 may be executed by the bidding process unit 28D of the AC server 20.

[0119] The grid operator server 30 transmits the power supply and demand adjustment request information, which is the DR event (step S124). The grid operator server 30 transmits the power supply and demand adjustment information to the AC server 20 via the market server 40 or to the market server 40, for example.

[0120] The selection unit 28E of the AC server 20 executes a selection process (step S126). In detail, the selection unit 28E of the AC server 20 selects a resource aggregator 2 that will execute power supply and demand adjustment according to the power supply and demand adjustment information, based on the remuneration management information corresponding to the system operator ID of the system operator 6 of the system operator server 30 that has transmitted the power supply and demand adjustment information, and the capacity management information of each of the multiple resource aggregators 2 managed by the AC server 20. The selection unit 28E selects a resource aggregator 2 that will execute power supply and demand adjustment from among the resource aggregators 2 that have won bids in the power tender determined by the successful bid processing unit 28D.

[0121] Then, the selection unit 28E further determines the requested adjustment power amount for each resource aggregator 2 that performs the power supply and demand adjustment in accordance with the power supply and demand adjustment request information, based on the remuneration management information and the capacity management information, so that the power supply and demand adjustment can be performed in a shorter adjustment time and with less remuneration, within the range of the successful bid power adjustment amount for the power public bidding information transmitted by the system operator server 30 of the system operator 6 that transmitted the power supply and demand adjustment request information.

[0122] The selection unit 28E of the AC server 20 transmits DR instruction information including the requested adjustment power amount determined for the resource aggregator 2 to the RA server 10 of the resource aggregator 2 selected to perform power supply and demand adjustment (step S128).

[0123] The processing unit 18 of the RA server 10 that has received the DR instruction information transmits DR execution instruction information to each of the devices that make up the one or more managed power supply and demand facilities 3 based on the DR instruction information. The processing unit 18 of the RA server 10 then receives adjustment result information from the devices that make up the managed power supply and demand facilities 3. The adjustment result information represents the amount of adjusted power that was actually adjusted by the devices that make up the power supply and demand facilities 3 during the adjustment period. The processing unit 18 of the RA server 10 transmits the adjustment result information, including the total value of the amount of adjusted power received from the devices that make up the managed power supply and demand facilities 3, to the AC server 20 (step S130).

[0124] As described above, the processing unit 18 of the RA server 10 may control the devices constituting one or more managed power supply and demand facilities 3 so as to adjust power supply and demand based on the DR instruction information. Then, the processing unit 18 may transmit adjustment result information obtained by the control to the AC server 20.

[0125] The remuneration derivation unit 28F of the AC server 20 derives a claimed remuneration for each resource aggregator 2 based on the adjustment result information received from the RA server 10 and the remuneration management information of the grid operator server 30 that is the sender of the power supply and demand adjustment request information (step S132). Then, the remuneration derivation unit 28F transmits claimed remuneration information including the derived claimed remuneration to the grid operator server 30 that is the sender of the power supply and demand adjustment request information (step S134). Then, this sequence ends.

[0126] Next, an example of the flow of information processing executed by the AC server 20 of this embodiment will be described.

[0127] FIG. 9 is a flowchart showing an example of the flow of information processing executed by the AC server 20 of this embodiment.

[0128] The DR contract processing unit 28A executes DR contract processing to conclude a contract regarding a demand response that adjusts the balance between power supply and demand among the AC server 20 of the aggregation coordinator 5, the RA server 10 of the resource aggregator 2, and the system operator server 30 of the system operator 6 (step S200).

[0129] The capacity management information update unit 28B updates the capacity management information of the devices constituting the power supply and demand facilities 3 that are managed by each of the RA servers 10 of the resource aggregators 2 that have concluded a DR contract (step S202).

[0130] When the bidding processing unit 28C acquires the power solicitation information from the grid operator server 30 (step S204), it executes bidding processing based on the acquired power solicitation information (step S206). For example, based on the power solicitation information including the solicited adjustment power amount and the capacity management information, the bidding processing unit 28C transmits bidding information including the bid-requested power adjustment amount of the resource aggregator 2 that can accommodate the solicited adjustment power amount to the grid operator server 30 that is the source of the power solicitation information.

[0131] The successful bid processing unit 28D executes the successful bid processing based on the successful bid information received from the grid operator server 30 (step S208). For example, the successful bid processing unit 28D determines the resource aggregator 2 identified by the RAID included in the successful bid information as the resource aggregator 2 that has won the power bidding represented by the power bidding information. Then, the successful bid processing unit 28D associates the grid operator ID that identifies the grid operator 6 of the grid operator server 30 that has transmitted the power bidding information with the successful bid power adjustment amount of the determined resource aggregator 2, and stores them in the storage unit 26.

[0132] When the selection unit 28E acquires power supply and demand adjustment request information from the system operator server 30 with which the DR contract was concluded in step S200 (step S210), it selects a resource aggregator 2 that will execute power supply and demand adjustment in accordance with the power supply and demand adjustment information based on the remuneration management information and the capacity management information (step S212). Then, the selection unit 28E further determines, based on the remuneration management information and the capacity management information, a requested adjustment power amount for each resource aggregator 2 that executes power supply and demand adjustment in accordance with the power supply and demand adjustment request information, so that power supply and demand adjustment can be executed in a shorter adjustment time and with a smaller remuneration within the range of successful bid power adjustment amounts for the power public bidding information transmitted by the system operator server 30 of the system operator 6 that transmitted the power supply and demand adjustment request information.

[0133] The selector 28E transmits DR instruction information including the requested adjustment power amount determined for the resource aggregator 2 to the RA server 10 of the resource aggregator 2 selected in step S212 (step S214).

[0134] The remuneration derivation unit 28F receives adjustment result information of the power supply and demand adjustment corresponding to the power supply and demand adjustment request information acquired in step S210 from the RA server 10 of the resource aggregator 2 that transmitted the DR instruction information in step S214 (step S216). Then, the remuneration derivation unit 28F derives a claimed remuneration for each resource aggregator 2 based on the received adjustment result information and the remuneration management information of the system operator server 30 that transmitted the power supply and demand adjustment request information (step S218).

[0135] The remuneration derivation unit 28F then transmits the claimed remuneration information including the derived claimed remuneration to the system operator server 30 that is the source of the power supply and demand adjustment request information (step S220), and then ends this routine.

[0136] Next, an example of the flow of the monitoring process executed by the processing unit 58 of the monitoring server 50 of this embodiment will be described.

[0137] FIG. 10 is a flowchart showing an example of the flow of information processing executed by the monitoring server 50 of this embodiment.

[0138] The RA server 10, AC server 20, grid operator server 30, and market trading server 40 included in the electricity supply and demand adjustment system 1 each simultaneously transmit communication data, which is data to be transmitted to other information processing devices, to the monitoring server 50. Therefore, the communication data includes various types of information, such as the above-mentioned remuneration management information, capacity management information, electricity public bidding information, bidding information, successful bid information, electricity supply and demand adjustment request information, DR instruction information, adjustment result information, and claimed remuneration information.

[0139] When the processing unit 58 receives communication data from each of the other information processing devices, namely the RA server 10, the AC server 20, the grid operator server 30, and the market trading server 40 (step S300), the processing unit 58 associates the received communication data with the reception date and time as a communication log and stores the data in the storage unit 56. The communication data may include identification information of the source information processing device and identification information of the destination information processing device.

[0140] The processing unit 58 stores the communication data as a communication log in the storage unit 56, which makes it possible to use the communication log as evidence of the transaction. The processing unit 58 may also apply a blockchain to the communication data before storing it in the storage unit 56.

[0141] The processing unit 58 analyzes the communication data received in step S300 to determine whether the communication data is abnormal (step S304).

[0142] For example, the processing unit 58 determines whether an invalid value is embedded in the communication data. Specifically, the processing unit 58 stores candidate values ​​that may be included for each type of communication data in advance. The processing unit 58 then analyzes the type of the received communication data using a known method, and if the communication data contains a value other than the candidate value corresponding to the analyzed type, determines that the communication data is abnormal.

[0143] Furthermore, the RA server 10, AC server 20, grid operator server 30, and market server 40 included in the power supply and demand adjustment system 1 may attach a known digital signature to communication data before transmitting it. In this case, the processing unit 58 may determine whether the digital signature is valid using a known method to determine whether the communication data is abnormal. Furthermore, the RA server 10, AC server 20, grid operator server 30, and market server 40 included in the power supply and demand adjustment system 1 may encrypt the communication data using a known encryption key or public key before transmitting it to another information processing device. In this case, the processing unit 58 may determine whether the communication data can be decrypted using a decryption key, public key, or the like to determine whether the communication data is abnormal.

[0144] Furthermore, the processing unit 58 may further monitor the frequency of the power flowing in the power grid 4. If there is a deviation of a predetermined frequency or more between the frequency of the power flowing in the power grid 4 and the estimated frequency of the power flowing in the power grid 4 when power supply and demand adjustment is performed in accordance with the power supply and demand adjustment request information, the processing unit 58 may determine that power supply and demand adjustment in accordance with the power supply and demand adjustment request information has not been performed and may determine that an abnormality has occurred in the communication data.

[0145] The processing unit 58 outputs the determination result of the abnormality of the communication data (step S306). If the processing unit 58 determines that the communication data is abnormal, it outputs information indicating the determination result of the abnormality to the UI unit 54 or a preset information processing device. For example, if the processing unit 58 determines that the communication data is abnormal, it transmits information indicating the determination result of the abnormality to at least one information processing device among the RA server 10, the AC server 20, the grid operator server 30, and the trading market server 40 in the power supply and demand adjustment system 1. The information processing device that receives the information indicating the determination result of the abnormality may perform control to suspend transactions related to demand response. Then, this routine ends.

[0146] In addition, at least a part of the above-mentioned monitoring processing performed by the processing unit 58 of the monitoring server 50 may be performed by at least one of the RA server 10, AC server 20, system operator server 30, and trading market server 40 included in the power supply and demand adjustment system 1.

[0147] As described above, the power supply and demand adjustment method executed by the AC server 20 of this embodiment, which is an example of a power supply and demand adjustment device, includes a selection unit step. The selection unit step selects, based on remuneration management information and capacity management information, one or more resource aggregators 2 that can adjust the supply and demand requested power amount indicated in the power supply and demand adjustment request information with a remuneration less than a threshold by the adjustment start time, as resource aggregators 2 that will perform power supply and demand adjustment in accordance with the power supply and demand adjustment request information. The remuneration management information is information that specifies remuneration information for each adjustment time required for the power supply and demand facility 3 to adjust power to a predetermined adjustment power amount, with higher remuneration being paid the shorter the adjustment time. The capacity management information is information that specifies the adjustment time for each of the one or more power supply and demand facilities 3 managed by the resource aggregator 2.

[0148] In this way, the power supply and demand adjustment method of this embodiment selects a resource aggregator 2 that will execute power supply and demand adjustment in response to the power supply and demand adjustment request information, which is a DR event, based on the remuneration management information and the capacity management information. That is, the power supply and demand adjustment method of this embodiment selects a resource aggregator 2 that will execute power supply and demand adjustment in response to the power supply and demand adjustment request information, using the remuneration and the adjustment time required to request power to a predetermined adjustment power amount, which is the capacity of the resource aggregator 2.

[0149] Therefore, the power supply and demand adjustment method of this embodiment can suitably select a resource aggregator 2 that can execute power supply and demand adjustment in response to power supply and demand adjustment request information, which is a DR event. Therefore, the power supply and demand adjustment method of this embodiment can suppress failures of demand response. Furthermore, because failures of demand response can be suppressed, the power supply and demand adjustment method of this embodiment can suppress a decrease in bids and successful bids in public electricity bidding. Furthermore, the AC server 20 of this embodiment selects a resource aggregator 2 that executes power supply and demand adjustment based on remuneration management information and capacity management information. Therefore, it is possible to suppress failures of demand response and select an effective resource aggregator 2.

[0150] Therefore, the electricity supply and demand adjustment method of this embodiment can provide suitable support for demand response trading.

[0151] The power supply and demand adjustment method of this embodiment also includes a bidding processing step and a winning bid processing step. The bidding processing step transmits bidding information including power adjustment amounts desired to be bid by resource aggregators 2 that can accommodate the offered adjustment power amount to the grid operator server 30 that is the source of the power bidding information, based on power bidding information including the offered adjustment power amount and capacity management information. The winning bid processing step determines a resource aggregator 2 that has won the power bidding represented by the power bidding information, based on the winning bid information received from the grid operator server 30 and including at least the successful bid power adjustment amount for the bidding information. Then, the selection step selects, from the determined resource aggregators 2, a resource aggregator 2 that will execute power supply and demand adjustment in accordance with the power supply and demand adjustment request information.

[0152] Therefore, the power supply and demand adjustment method of this embodiment can select, based on the capacity management information, a resource aggregator 2 that will perform power supply and demand adjustment in accordance with the power supply and demand adjustment request information from among the resource aggregators 2 that have won the power tender represented by the power tender information.

[0153] Therefore, in addition to the above-mentioned effects, the power supply and demand adjustment method of this embodiment can further suppress a decrease in bids and successful bids in public tenders for power, and failures of demand response.

[0154] In addition, the power supply and demand adjustment method of this embodiment receives adjustment result information of the power supply and demand adjustment in response to the power supply and demand adjustment request information from the RA server 10 of the resource aggregator, and derives a billing remuneration for each resource aggregator 2 based on the adjustment result information and remuneration management information.

[0155] Therefore, the power supply and demand adjustment method of this embodiment can derive a claimed remuneration according to the remuneration management information for each resource aggregator 2 .

[0156] The power supply and demand adjustment method of this embodiment also includes a monitoring step of monitoring abnormalities in communication data within the power supply and demand adjustment system 1 including the AC server 20, which is an example of a power supply and demand adjustment device.

[0157] Therefore, the power demand and supply adjustment method of this embodiment can prevent demand response failures and a decrease in bids and successful bids due to tampering with communication data, etc.
