Description

  The present invention generally relates to demand response technology.

  The demand response technique is an effective technique for controlling power consumption on the demand side. Regarding demand response technology, there is an aggregator that issues a command to a plurality of lower systems (for example, a consumer computer or facility equipment, and integrates and manages them as a whole. A power adjustment specifying the requested amount (power to be adjusted) is transmitted.

  As a technique for performing a demand response to a plurality of consumers, there is a technique disclosed in Patent Document 1. In the technique of Patent Document 1, the order for each consumer is realized by calculating based on an area information database in which area priorities set for each consumer attribute are associated with different conditions.

JP 2016-214084 A

  The technique of Patent Document 1 described above ranks consumers by using a plurality of indexes, but is finally integrated into one rank. That is, one order is assigned to each consumer. Since the ranking is finally one, the ranking is likely to be fixed, and as a result, it is considered that inappropriate distribution of the power adjustment amount occurs. In addition, the objective function in the optimization calculation may have multimodality because it becomes multivariable by a plurality of indices. For this reason, even if the input condition is changed minutely in the optimization calculation, the solution may change greatly. In this case, for example, when power adjustment is performed for a lower-level aggregator and then power adjustment is performed again using the recalculation result due to a change in conditions, a calculation result different from the previously calculated request amount is calculated. This makes it difficult to adjust the power on the aggregator side.

  An object of the present invention is to appropriately distribute the power adjustment amount.

  The power adjustment control device responds to the command value specifying the adjustment amount of the power (supplied or consumed power or electric energy) according to the distribution rule according to each of the plurality of indexes related to the power adjustment, Are allocated to two or more request amounts corresponding to a plurality of indexes respectively designated by two or more adjustment requests transmitted to one or more lower-level systems. Each lower system is a system that, when receiving an adjustment request for the system, performs power adjustment for the requested amount specified in the adjustment request in response to the adjustment request. The power adjustment control device transmits each of the two or more adjustment requests each having two or more request amounts specified to the lower system that is the transmission destination of the adjustment request. When calculating the amount of adjustment requests, for example, by fixing the distribution ratio of multiple indicators, it is possible to obtain nearby calculation results without the calculation results changing significantly due to minute changes in input conditions. It becomes.

  According to the present invention, it is possible to realize an appropriate distribution of the power adjustment amount in consideration of a plurality of indexes related to the power adjustment.

A power supply and demand adjustment system according to an embodiment of the present invention will be described with reference to the drawings.
[First embodiment]

  FIG. 1 is a schematic block diagram of a power supply and demand adjustment system according to the first embodiment.

  Referring to FIG. 1, the power supply and demand adjustment system includes a higher level DRAS (Demand Response Automation Server) 11, a DRAS 12, a lower level DRAS 13, and a resource group 14. In the description of this embodiment, “upper DRAS” means a system that is connected to the upper level of DRAS 12 and is designated as a VTN (Virtual Top Node) in OpenADR2.0. “Lower DRAS” means a system connected to a lower level of DRAS 12 and set to VEN (Virtual End Node) in OpenADR2.0.

  A plurality of lower DRASs 13 are connected to the DRAS 12. The DRAS 12 is an example of a power adjustment control device. The DRAS 12 may be one or more physical or virtual computers, or may be a software-defined device realized on one or more computing resources such as a cloud infrastructure.

  The upper DRAS 11 is a device that transmits a power adjustment command value (a command value specifying a power adjustment amount) to the DRAS 12. The upper DRAS 11 is an example of a command value transmission source. The command value may be transmitted from the input / output console of the DRAS 12 (for example, a client computer of the DRAS 12 or an input device such as a keyboard and a pointing device connected to the DRAS 12) instead of or in addition to the upper level DRAS 11. Good. That is, a command value may be input from an operator (an example of a user) via the input / output console.

  The DRAS 12 receives a command value from the host DRAS 11 or the operator, and in response to the command value, distributes the adjustment amount to two or more request amounts (hereinafter also referred to as adjustment request amounts), and This is an apparatus that transmits each of two or more adjustment requests each having two or more adjustment request amounts specified to the lower DRAS 13 that is the transmission destination of the adjustment request.

  The lower level DRAS 13 is a device that controls the resource group 14. One or more of the resources in the lower level DRAS 13, the resource group 14, and the resource group 14 is an example of the lower level system. The lower system is a system that, when receiving an adjustment request for the device, performs power adjustment for the requested amount specified in the adjustment request in response to the adjustment request.

  The resource group 14 is one or more resources. The resource is a device that adjusts the power load. For example, the resource may be a storage battery, a hot water supply facility for each household, an EV (Electric Vehicle), or the like. That is, the resource may be either a power consuming device that consumes power or a power supply device that supplies power.

  A customer related to each subordinate DRAS 13 has a contract for demand adjustment with a business operator related to DRAS 12, for example. Each subordinate DRAS 13 receives an adjustment request for the subordinate DRAS 13 from the DRAS 12, and performs power adjustment on the adjustment request and responds to the DRAS 12 with the result, or responds to the DRAS 12 that power adjustment is not performed. Or

  Each lower-level DRAS 13 adjusts the amount of the resource group 14 to the DRAS 12 regularly or irregularly (power that the DRAM 13 can adjust to the resource group 14 (power or amount of power to be supplied or reduced) And an adjustment result (for example, an adjustment amount (power or electric energy that has been reduced in supply or consumption) at the time of actual power adjustment) is notified.DRAS 12 can adjust the command value received from the lower DRAS 13 In consideration of the amount and the adjustment results, the adjustment request amount to be distributed to the lower DRAS 13 is determined, or whether or not the lower DRAS 13 is the transmission destination of the adjustment request is determined.

  The lower level DRAS 13 responds to the adjustment request received from the DRAS 12, whether or not adjustment is possible, controls the resource group 14 if adjustment is possible, and transmits the adjustment result, which is a result of the control, to the DRAS 12. .

  If the lower level DRAS 13 cannot be adjusted, the lower level DRAS 13 transmits a response indicating that adjustment is not possible to the DRAS 12. When the DRAS 12 receives a response indicating that adjustment is impossible, or when it is determined that the adjustment request cannot be achieved from the adjustment results of the lower DRAS 13, the power adjustment according to the adjustment amount specified by the command value from the higher DRAS 11 is achieved. Can not. For this reason, the DRAS 12 distributes the request amount that cannot be adjusted to two or more request amounts, and two or more adjustment requests that respectively specify the two or more request amounts, It transmits to two or more lower level DRAS13. Each of the two or more subordinate DRASs 13 responds to the adjustment request whether or not adjustment is possible, and controls the resource group 14 if adjustment is possible.

  FIG. 2 is a schematic block diagram showing the configuration of the DRAS 12 according to the present embodiment.

  Referring to FIG. 2, the DRAS 12 includes a storage unit 23, a calculation unit 22, and a communication unit 21 as a basic configuration. The calculation unit 22 is connected to the communication unit 21 and the storage unit 23.

  The storage unit 23 is a storage device that stores data. The storage unit 23 stores setting information, contract information about each lower level DRAS 13, command values, adjustable amounts, event responses, and adjustment results. The storage unit 23 may be at least one of the memory unit and at least a part of the PDEV unit (typically at least the memory unit). The “memory unit” is one or more memories, and may typically be a main storage device. At least one memory in the memory unit may be a volatile memory or a non-volatile memory. The “PDEV unit” is one or more PDEVs, and may typically be an auxiliary storage device. “PDEV” means a physical storage device, typically a non-volatile storage device such as a hard disk drive (HDD) or a solid state drive (SSD).

  The arithmetic unit 22 adjusts the adjustment amount specified by the command value according to the priority order and the distribution ratio associated with each of the plurality of indexes related to the power adjustment based on the data stored in the storage unit 23. Allocate the sub-adjustment amount for each indicator. For each index, the calculation unit 22 selects, for each of one or more adjustment requests, the lower DRAS 13 that is the transmission destination of the adjustment request, and the request amount (all or a part of the sub adjustment amount) to be allocated to the lower DRAS 13. Is calculated. Note that the calculation unit 22 may be one or more processors. The at least one processor is typically a microprocessor such as a CPU (Central Processing Unit), but may be another type of processor such as a GPU (Graphics Processing Unit). At least one processor may be a single core or a multi-core. The at least one processor may be a processor in a broad sense such as a hardware circuit (for example, a field-programmable gate array (FPGA) or an application specific integrated circuit (ASIC)) that performs part or all of the processing.

  The communication unit 21 is a device that communicates with the upper DRAS 11 and the lower DRAS 13. The communication unit 21 receives a command value from the upper DRAS 11. The received command value is stored in the storage unit 23. Further, the communication unit 21 receives the adjustable amount, the event response, and the adjustment result from the lower level DRAS 13. The received adjustable amount, event response, and adjustment results are stored in the storage unit 23. In addition, the communication unit 21 transmits an adjustment request in which the adjustment request amount calculated by the calculation unit 22 is specified to the lower level DRAS 13. Note that the communication unit 21 may be one or more interfaces. The one or more interfaces may be one or more similar communication interface devices, or two or more different communication interface devices.

  FIG. 3 is a block diagram of the DRAS 12 according to the embodiment.

  The calculation unit 22 includes a command value reception unit 211, an adjustment result reception unit 212, an adjustment request transmission unit 213, an event response reception unit 214, an adjustable amount reception unit 215, a request amount calculation unit 221, and an association determination unit 222. The command value receiving unit 211, the adjustment result receiving unit 212, the adjustment request transmitting unit 213, the event response receiving unit 214, the adjustable amount receiving unit 215, the request amount calculating unit 221 and the association determining unit 222 have one or more computers. The program may be realized by being executed by the arithmetic unit 22, or may be realized by one or more hardware circuits (for example, FPGA or ASIC). When the above-described function is realized by the program being executed by the calculation unit 22, since the determined process is appropriately performed using the storage unit 23 and / or the communication unit 21, the function is the same as that of the calculation unit 22. It may be at least partly. The processing described with the function as the subject may be processing performed by the calculation unit 22 or a device (DRAS 12) having the calculation unit 22. The program may be installed from a program source. The program source may be, for example, a program distribution computer or a computer-readable recording medium (for example, a non-transitory recording medium). The description of each function is an example, and a plurality of functions may be combined into one function, or one function may be divided into a plurality of functions.

  The storage unit 23 stores an index DB 231, a contract DB 232, a command value DB 233, an adjustable amount DB 234, an adjustment performance DB 235, a request amount DB 236, and an event response DB 237. “DB” is an abbreviation for database. In the present embodiment, information that can be output with respect to an input will be described using an expression such as “xxxDB”. However, the information may be data having any structure, and the information of the neural network that generates output with respect to the input may be used. Such a learning model may be used. Therefore, “xxxDB” can be referred to as “xxx information”. One DB (for example, a table) may be divided into two or more DBs, or all or a part of the two or more DBs may be a single DB.

  The host DRAS 11 transmits a command value (power adjustment command) specifying the power adjustment amount to the DRAS 12. In the DRAS 12, the command value receiving unit 211 receives the command value via the communication unit 21 and stores it in the received command value DB 233. Alternatively, the command value receiving unit 211 receives a command value from the operator via the above-described input / output console (for example, GUI (Graphical User Interface)), and stores the command value in the command value DB 233. The command value DB 233 may include, for example, the reception date and time of the command value and identification information of the command value transmission source (for example, the upper DRAS 11) for each command value. The command value may be stored in a storage area for temporarily storing information, such as a buffer, instead of being stored in the DB.

  In the index DB 231, at least a distribution ratio is associated with the priority order and the distribution ratio for each of the plurality of indices. For example, as illustrated in FIG. 5, the index DB 231 stores information indicating an index name, a priority order, and a distribution ratio for each of a plurality of indices. Information indicating the index name, priority, and distribution ratio may be stored by inputting a fixed value from the operator via the above-described input / output console. According to the relationship between the index illustrated in FIG. 5 and the distribution ratio, assuming that the adjustment amount specified by the command value is “100” (for example, kW or kWh), among the adjustment amounts “100”, “ 50 is allocated for the index “cost”, “30” is allocated for the index “responsiveness”, and “20” is allocated for the index “fairness”. Each of “50”, “30”, and “20” referred to here is an example of the sub adjustment amount allocated from the adjustment amount. Each sub-adjustment amount is distributed to one or more requested amounts. Specifically, for example, the sub-adjustment amount “50” is allocated to the request amount “28” and the request amount “22”, and the two adjustment requests in which the two request amounts are respectively designated are the two subordinate requests. It may be transmitted to the DRAS 13. Note that the relationship illustrated in FIG. 5 (the relationship between the index, the priority order, and the distribution ratio) may be common to all the upper DRASs 11 and all the lower DRASs 13, or may differ depending on a predetermined unit (for example, region). May be. Regarding the priority order, in the example of FIG. 5, the smaller the numerical value, the higher the priority order. In the present embodiment, “cost”, “responsiveness”, and “fairness” are provided as a plurality of indexes. “Cost” is a cost (for example, a product of reduced power and unit price, or a calculation load related to power adjustment) related to implementation of power adjustment. “Response” means the difference between the adjustment request amount and the adjustment result (the degree of follow-up of the adjustment result with respect to the adjustment request amount). “Fairness” means a small variation in the request amount or the transmission destination of the adjustment request.

  The contract DB 232 holds information regarding the contract for each lower level DRAS 13. For each subordinate DRAS 13, the information regarding the contract may include a cost (unit price) per unit power.

  The adjustment result receiving unit 212 receives information indicating the adjustment result from the lower level DRAS 13 periodically or irregularly (for example, as a response to the adjustment request) via the communication unit 21, and receives information indicating the adjustment result. And stored in the adjustment result DB 235. The adjustment record DB 235 stores information indicating the adjustment record for each lower level DRAS 13. For each subordinate DRAS 13, the information indicating the adjustment result is, for example, for each of one or more adjustment requests received in the past, the reception date and time of the adjustment request, whether or not the adjustment request has been performed on the adjustment request, Information indicating the adjustment amount of the power adjustment performed for the request amount specified in the adjustment request and information indicating an index (for example, an index name) corresponding to the adjustment request among a plurality of indexes may be included.

  In the adjustable amount receiving unit 215, information indicating power (adjustable amount) that can be adjusted by the resource group 14 connected to the lower DRAS 13 is transmitted via the communication unit 21 from the lower DRAS 13 periodically or irregularly. And information indicating the adjustable amount is stored in the adjustable amount DB 234. The adjustable amount DB 234 stores information indicating the latest adjustable amount for each lower level DRAS 13.

  The event response receiving unit 214 receives an event response, which is information indicating whether or not power adjustment can be performed, from the lower level DRAS 13 regularly or irregularly (for example, as a response to the adjustment request) via the communication unit 21. The event response is stored in the event response DB 237. The event response DB 237 stores all received event responses (or event responses in the latest fixed period) for each lower level DRAS 13.

  The adjustment request transmission unit 213 acquires the adjustment request amount calculated by the calculation unit 22 and is an adjustment request amount for a certain lower level DRAS from the request amount DB 236, and sends the adjustment request specifying the acquired adjustment request amount to the lower level DRAS 13. It transmits via the communication unit 21.

  In response to the command value (in this embodiment, the command value acquired from the command value stored in the command value DB 233), the requested amount calculation unit 221 performs the command value according to the distribution rule according to each of the plurality of indices. Are allocated to two or more request amounts corresponding to a plurality of indexes respectively specified by two or more adjustment requests transmitted to one or more lower DRAS 13 among the plurality of lower DRASs 13. . The requested amount calculation unit 221 selects, for each requested amount, a lower level DRAS 13 as a transmission destination from a plurality of lower level DRAS 13 (for example, a plurality of lower level DRAS 13 registered in the contract DB 232). The requested amount calculation unit 221 stores information indicating each requested amount in the requested amount DB 236. At that time, for each requested amount, the lower-level DRAS 13 of the transmission destination of the requested amount is associated. That is, the request amount DB 236, for example, for each lower level DRAS 13, the allocated request amount, the identification information of the command value specifying the adjustment amount that is the basis of the request amount, and the transmission source of the command value Information such as identification information may be stored. Each of the two or more adjustment requests each specifying two or more request amounts is transmitted by the adjustment request transmission unit 213 to the subordinate DRAS 13 that is the transmission destination of the adjustment request. Since the power adjustment amount is distributed in consideration of a plurality of indexes related to the power adjustment, an appropriate distribution of the power adjustment amount can be realized. For each index, the “distribution rule” is a rule as to which one or more lower systems are to transmit the portion to which the adjustment amount is distributed as an adjustment request.

  The request amount calculation unit 221 makes two or more requests for the adjustment amount specified by the command value based on the distribution ratio (distribution ratio specified from the index DB 231) associated with each of the plurality of indexes. Allocate to quantity. As a result, the power adjustment amount can be distributed for each index in an amount corresponding to the distribution ratio defined for the index, and as a result, it is possible to contribute to appropriate distribution of the power adjustment amount.

Specifically, for example, the requested amount calculation unit 221 performs the following (A) and (B) for each of the plurality of indices. As described below, for each index, a part of the adjustment amount such as the sub adjustment amount is obtained, and the sub adjustment amount is distributed to one or more requested amounts. Thereby, for each index, distribution according to the index (allocation of adjustment amount) is expected.
(A) A sub-adjustment amount that is an amount according to the distribution ratio associated with the index associated with the priority is calculated among the adjustment amounts.
(B) According to the distribution rule corresponding to the index, the calculated sub-adjustment amount is distributed to one or more requested amounts, and an adjustment in which the requested amount is specified for each of the one or more requested amounts Determine the subsystem to which the request is sent.

  The determination (selection) of the lower-layer DRAS 13 as the transmission destination is made by adjusting the adjustable amount (adjustable amount specified from the adjustable amount DB 234) and the adjustment result (adjustment result specified from the adjustment result DB 235) for each of the plurality of lower-layer DRASs 13. And at least one of the following. For example, if a certain request amount is equal to or less than an adjustable amount of a certain lower level DRAS 13, the lower level DRAS 13 is selected as a transmission destination of the request amount. In addition, for example, the lower DRAS 13 having a relatively high rate of successful power adjustment according to the adjustment request is preferentially the destination of the request amount (for example, an adjustable amount greater than a certain request amount is provided) When there are two or more subordinate DRASs 13 to be executed, the subordinate DRAS 13 having the highest rate of successful power adjustment according to the adjustment request is selected as a transmission destination from the two or more subordinate DRASs 13). This is expected to increase the success rate of power adjustment according to the adjustment request.

  As described above, a priority order is associated with each of the plurality of indexes, and the power adjustment amount is distributed according to the priority order. As a result, it is expected to realize an appropriate distribution of the power adjustment amount.

  Specifically, for example, the above-described (A) and (B) are executed in order from the index with the highest priority. Thereby, it is expected that the higher the priority index, the higher the power adjustment success rate.

  More specifically, for example, in (A) and (B), each time the transmission destination lower DRAS 13 is determined, the request amount calculation unit 221 determines the lower DRAS 13 based on the request amount for the lower DRAS 13. (For example, in the adjustable amount DB 234, the requested amount is subtracted from the adjustable amount corresponding to the lower DRAS 13). As a result, at least a part of the adjustable amount of the lower DRAS 13 is assigned (used) in order of higher priority. For this reason, it is expected that the higher the priority index, the higher the power adjustment success rate.

The adjustment request amount is calculated by repeating the distribution in order from the highest priority index based on the priority order of each index set in the index DB 231. Specifically, when the event response received by the event response receiving unit 214 is not adjustable, or when it is determined from the adjustment results received by the adjustment result receiving unit 212 that power adjustment for the adjustment request amount is impossible. The requested amount calculation unit 221 executes at least (B) of (A) and (B) again for the index corresponding to the requested amount that has become unadjustable. That is, at least one of the following may be performed. As a result, it is expected to realize an appropriate distribution of the power adjustment amount.
-Another lower DRAS 13 is selected as the transmission destination of the request amount that cannot be adjusted.
The request amount that has become unadjustable is distributed to two or more request amounts, and for each of the two or more request amounts, the subordinate DRAS 13 that is the transmission destination of the request amount is the adjustable amount DB 234 and the adjustment result DB 235. The selection is based on at least one of the above.
・ Re-distribute the adjustment amount from the beginning. At this time, the lower level DRAS 13 corresponding to the inability to adjust is excluded from the options.

  The association determination unit 222 determines a distribution ratio (distribution ratio in the index DB 231) associated with each of the plurality of indexes based on the adjustment results (adjustment results specified from the adjustment result DB 235) for each of the plurality of indexes. (For example, a distribution ratio corresponding to an index with a relatively low success rate of power adjustment is set as a relatively low distribution ratio). The adjustment performance for each index includes an adjustment amount of power adjustment performed for each of one or more requested amounts specified in the past for the index. As a result, the relative distribution ratio for each of the plurality of indexes is updated based on the adjustment results. Thereby, it is expected that the power adjustment amount is more appropriately distributed.

  In addition, the association determination unit 222 sets the priority order (priority order in the index DB 231) associated with each of the plurality of indexes based on the adjustment results (adjustment results specified from the adjustment result DB 235) for each of the plurality of indexes. (For example, a priority corresponding to an index with a relatively low success rate of power adjustment is set as a relatively high priority). As a result, the relative priority for each of the plurality of indices is updated based on the adjustment record. Thereby, it is expected that the power adjustment amount is more appropriately distributed. When calculating the adjustment request amount, for example, by fixing the distribution ratio in a plurality of indexes, the calculation amount in the vicinity is obtained without greatly changing the request amount calculated by a minute change in the input condition. It becomes possible.

  FIG. 4 is a flowchart of the request amount calculation unit 221 according to the first embodiment.

  In step 101, the requested amount calculation unit 221 acquires a command value from the command value DB 233.

  In step 102, the requested amount calculation unit 221 acquires the adjustable amount of each lower level DRAS 13 from the adjustable amount DB 234. The requested amount calculation unit 221 may further acquire the adjustment results of each lower level DRAS 13 from the adjustment result DB 235.

  In step 103, the requested amount calculation unit 221 determines the adjustment amount specified by the command value acquired in step 101 based on a plurality of distribution ratios (a plurality of distribution ratios respectively corresponding to the plurality of indexes) indicated by the index DB 231. And split. As a result, a sub-adjustment amount corresponding to the distribution ratio of the index is obtained for each index.

  In step 104, the requested amount calculation unit 221 selects an index in descending order of priority set in the index DB 231 and performs the subsequent processing. In the setting example illustrated in FIG. 5, the request amount calculation unit 221 first processes the sub-adjustment amount based on the distribution rule corresponding to the cost, and then, the sub amount corresponding to the responsiveness based on the distribution rule corresponding to the responsiveness. The adjustment amount is processed, and finally the sub adjustment amount corresponding to fairness is processed based on the distribution rule corresponding to fairness.

  In step 105, the requested amount calculation unit 221 uses the sub-adjustment amount (sub-adjustment amount obtained in step 103) corresponding to the index selected in step 104 as the adjustable amount (and the adjustment result) of each of the plurality of lower DRASs 13. ) To allocate to one or more requested quantities.

  For example, a distribution method based on cost, responsiveness, and fairness will be described. Note that the allocation rule according to cost is at least one of preferentially allocating a larger amount of request and preferentially setting the destination of the adjustment request as the lower DRAS 13 having a lower unit price (cost per unit power). , That is the rule. The distribution rule according to the responsiveness indicates that the lower DRAS 13 having a smaller difference between the past requested amount and the adjustment amount of the power adjustment actually performed in the past (for example, the adjustment amount specified from the adjustment result DB 235) is preferentially requested amount. This is a rule of performing at least one of distributing a large amount of data and preferentially setting a transmission destination of an adjustment request. The distribution rule according to fairness is preferentially given to the lower DRAS 13 in which at least one of the past request amount and the number of adjustment requests transmitted in the past (for example, the number of adjustment requests specified from the adjustment result DB 235) is relatively small. This is a rule that performs at least one of allocating a large amount of request and preferentially making the adjustment request a transmission destination.

  The cost of each lower level DRAS 13 is calculated by the request amount calculation unit 221 from the unit price corresponding to the lower level DRAS 13 (unit price specified from the contract DB 232), for example. For example, if the adjustable amount of the lower-order DRAS 13 with the lowest cost is equal to or larger than the requested amount, the requested amount calculation unit 221 allocates the entire sub-adjustment requested amount corresponding to the cost as the requested amount to the lower-level DRAS 13. Good. For example, if the adjustable amount of the lower-order DRAS 13 with the lowest cost is less than the requested amount, the requested amount calculation unit 221 allocates a part of the sub-adjustment amount corresponding to the cost as the requested amount to the lower-order DRAS 13. The request amount to be allocated to the lower DRAS 13 may be determined based on the adjustable amount of the lower DRAS 13 having the next lowest cost. In this process, the request amount per lower DRAS 13 and the increase of adjustment requests (increase in the number of sub-adjustment amount distributions) may be performed based on the adjustment results. Such control of the number of sub-adjustment amounts can be controlled for at least one index other than cost.

  The responsiveness of each subordinate DRAS 13 is calculated by the request amount calculation unit 221 from the adjustment request amount that has been implemented in the past and the actual adjustment results. The requested amount calculation unit 221 preferentially distributes to the lower DRAS 13 in which the difference between the adjustment requested amount and the adjustment performance (for example, the actually adjusted power) is small.

  The fairness of each subordinate DRAS 13 is calculated by the request amount calculation unit 221 from the number of times that an adjustment request has been transmitted (for example, the number specified from the adjustment performance DB 235) with respect to the number of times of demand response in the past. Allocation is preferentially performed for the lower DRAS 13 having a small ratio (for example, a ratio specified from the adjustment record DB 235) that is the transmission destination of the adjustment request.

  In step 106, the request amount calculation unit 221 subtracts the request amount allocated in step 105 (request amount assigned to the lower DRAS 13) from the adjustable amount of the lower DRAS 13. As a result, the adjustable amount DB 234 is updated.

  In step 107, the requested amount calculation unit 221 determines whether or not steps 104 to 106 have been performed for all indexes. If the determination result in step 107 is false (step 107: NO), the process returns to step 104.

  When the determination result in step 107 is true (step 107: YES), in step 108, the request amount calculation unit 221 stores the calculated request amounts in the request amount DB 236. At that time, the request amount calculation unit 221 assigns (associates) the request amount to the lower-level DRAS 13 of the transmission destination of the request amount for each calculated request amount.

According to the present embodiment, it is possible to realize appropriate distribution of the power adjustment amount by taking into account a plurality of indexes related to power adjustment. For example, the requested amount can be allocated by the index of responsiveness or fairness to the lower level DRAS 13 where the cost is high and the command amount is not allocated and the request is not made only by the cost index. As a result, a more appropriate adjustment amount can be distributed.
[Second Embodiment]

  Below, 2nd embodiment of this invention is shown. The description of the second embodiment mainly includes differences from the first embodiment, and the description of the common points with the first embodiment is omitted or simplified.

  As a plurality of indices related to power adjustment, one or more indices may be employed instead of or in addition to at least one of cost, responsiveness, and fairness. For example, at least one of a participation rate, a rejection rate, a non-performance rate, and an active participation request may be adopted as an index. The distribution rule according to the participation rate is that a lower system (for example, the lower DRAS 13) with a higher participation rate for the power adjustment solicitation for a certain period in the past from the reference time (for example, the current time) preferentially distributes the requested amount more preferentially. It is a rule that is performed at least one of preferentially making the adjustment request transmission destination. The distribution rule according to the refusal rate is that a lower system with a higher non-participation rate for power adjustment solicitation in the past than a certain period from the reference time will preferentially allocate a smaller amount of requests and send adjustment requests preferentially. Rules that do at least one of excluding. The distribution rule according to the default rate is that the lower system with a higher rate of non-executability for an adjustment request that specifies a request amount that is less than or equal to the reconcileable amount that has been answered, will preferentially allocate a smaller amount of request. It is a rule that performs at least one of exclusion from the transmission destination of the adjustment request. The distribution rule according to the request for active participation is that the lower priority system that actively issues the power adjustment regardless of whether or not there is a call for power adjustment, the priority is to distribute the requested amount more preferentially. It is a rule that at least one of the adjustment request transmission destination. Specifically, for example, it is as follows.

  Participation rate refers to an application for the number of notices of adjustment requests regarding a management unit such as a customer or equipment by performing a contract for power adjustment (for example, a contract is a contract related to power adjustment throughout the year, for example). Or an adjustment amount to be applied for the contract capacity (for example, kW or kWh). In one example, the notice is made one week in advance.

  The refusal rate is a rate related to the number of unadjustable responses to an adjustment request or the amount of unadjustable responses (for example, kW or kWh) for a management unit such as a customer or facility that has applied for a notice.

  With this process, it can be expected that the amount of requests or the number of adjustment requests to a management unit with a high rejection rate is reduced and the redistribution calculation cost is suppressed (in other words, the success rate of power adjustment according to the adjustment request is increased). Alternatively, when there is a margin in the adjustable amount of a management unit with a high rejection rate, the request amount or the number of adjustment requests to the management unit may be increased as an exception.

  Non-performing rate refers to the rate at which power adjustment could not be performed even though the requested amount was less than or equal to the adjustable amount that was received, related to the management unit such as the customer or facility that answered the adjustable amount ( For example, the ratio of the number of failures to the number of adjustment requests, or the ratio of unachieved power to the amount of requests.

  With this process, it is possible to reduce the number of requests for adjustment and the amount of requests to a management unit with a high default rate, and to suppress the deviation between the adjustment results and the planned value (request amount). Alternatively, when there is a margin in the adjustable amount of a management unit having a high default rate, the request amount or the number of adjustment requests to the management unit may be exceptionally increased.

  Further, the default rate may be either a default default rate or an active default rate.In the present embodiment, the default cause determination processing unit for determining faulty default and active default regarding the adjustment amount of the performance. Is provided.

  The default cause determination process may be performed by analysis of meter data, or the user may input an identification flag.

  For the analysis of meter data, refer to the time series data of actual power consumption obtained from measuring devices for power consumption of consumers or facilities (smart meters that measure at intervals such as every 30 minutes or every 5 minutes) Extract power consumption patterns for normal time periods when demand is not adjusted, and normal power consumption patterns for the time periods when the command value was set and for the time periods before and after If there is no difference, it is determined to be active non-performance, and if there is a difference from the normal power consumption pattern (particularly the commanded reduction in power consumption, or the difference from the normal time to increase consumption) May be determined to be accidental default.

  For extraction of power consumption patterns, representative patterns may be extracted by discretizing power consumption time-series data and performing data cluster analysis.

  The DRAS 12 can display the review of the contract conditions from the determination of the negligent default rate and the positive default rate to the management unit with a high positive default rate. It will be possible to consider revising the next contract terms.

  In the above, the data relating to the adjustable amount may be data relating to the applied value, or data generated based on the results. Furthermore, the data relating to the application or the result may be corrected using the deviation rate between the applied data and the past result data as a weight. By such processing, it is possible to avoid issuing an adjustment request command amount that cannot be realized from calculation of an excessive or excessive adjustable amount.

  An active participation request is to actively issue (participation) that power adjustment is performed regardless of whether or not there is a call for power adjustment. An adjustment request or request to a management unit that wants to receive a command value as much as possible (ie, a management unit with relatively high aggressiveness) among management units such as customers or facilities that have contracts for power adjustment (demand adjustment) The amount can be increased. In addition, although supply and demand adjustment contracts are made for social contribution and the like, it is possible to reduce the amount of requests or the number of adjustment requests to customers who desire not to perform power adjustment.

  In the above, the management unit may be a unit including at least one of the resource, the resource group 14, and the lower level DRAS 13, in other words, an example of the lower level system.

  In the above, adjustment (electric power adjustment) is the adjustment (power saving) in the direction of reduction in the amount of power received by lower systems such as consumers and equipment, and the adjustment in the direction of increase in the amount of power received in lower systems (charge amount to storage battery) Any adjustment of (increased).

  The amount of adjustment is allocated using two or more indicators of cost, responsiveness, fairness, participation rate, refusal rate, non-performance rate, and active participation request. It goes without saying that the present invention is not limited to the above-described embodiment, and it is possible to use an index other than the index given in the above-described embodiment. For example, indicators related to power adjustment are spread by, for example, indicators related to environmental impacts (indexes related to the arrival of smoke emitted from facilities to urban areas) and indicators related to traffic obstacles (decreasing facility availability) It may be an index related to the impact on traffic transport) or an index related to industrial obstacles (an index related to the impact on production).
