Description

[Technical field]

[0001] The present invention relates to a dispatch plan creating device and a program. [Background technology]

[0002] In recent years, demand response, which changes the power demand by controlling the power generation equipment, power storage equipment, and power consumption equipment (hereinafter collectively referred to as energy resources) on the consumer side at the request of the power transmission and distribution company, has been attracting attention. In demand response, an aggregator receives a command value from the electric power company and performs integrated control of multiple energy resources to achieve the target power generation amount that is the command value or a certain range including the command value.

[0003] The aggregator creates a dispatch plan, which is a plan for the integrated control, immediately before starting the integrated control. The dispatch plan includes the control setting values ​​of all energy resources to be controlled in a unit time period (control setting values ​​are considered to include not only set temperature and inverter frequency, but also whether the energy resources are activated or deactivated). A unit time period is the smallest unit of time interval in which the control setting values ​​of the energy resources cannot be changed midway. Aggregators generally enter into contracts with electric power companies under which disadvantages such as penalty fees will occur if the target power generation amount is not achieved. Therefore, when an aggregator creates a dispatch plan, it is desirable to create a highly accurate dispatch plan that can achieve the target power generation amount as much as possible (Patent Document 1). [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent No. 6837761 Summary of the Invention [Problem to be solved by the invention]

[0005] However, there are cases where the amount of power generated by each of multiple energy resources is unknown, but the total amount of power generated by these multiple energy resources is measured (hereinafter, a collection of such energy resources is called an energy resource group). For example, in a situation where an energy resource has never generated power (including power saving) independently in the past, and generating power just to check this is costly and therefore should be avoided, the amount of power generated by each individual energy resource is unknown. In this case, each energy resource group is regarded as a single group, and a dispatch plan is created for each energy resource group, assuming that all energy resources in the energy resource group can be in one of two states: either to activate a demand response or not.

[0006] However, this method has only two options: either fully utilize the power generation capacity of the energy resource group or not at all, and there is a problem that it is not possible to create a dispatch plan that partially utilizes the power generation capacity. This property of not being able to create a dispatch plan that partially utilizes the power generation capacity causes various problems in practice. For example, if a demand response is activated for all energy resources belonging to the energy resource group, the total power generation amount (including negawatts) of the dispatch plan obtained by this activation exceeds the target power generation amount, and if the target power generation amount is not reached if all are not activated, a situation may occur where only a dispatch plan that cannot achieve the target power generation amount can be created. Such a problem is not taken into consideration in Patent Document 1.

[0007] An object of the present invention is to make it possible to generate a highly accurate dispatch plan. [Means for solving the problem]

[0008] In order to solve the above problems, a dispatch plan creation device according to the present invention includes an acquisition unit that acquires, as a first relationship, a relationship between a control content of an energy resource group, which may be a content for exhibiting a part of a power generation capacity of the energy resource group, and a first predicted value that is a predicted value of a power generation amount of the energy resource group when the control content is adopted, and a creation unit that identifies a control content of the energy resource group that achieves a target power generation amount based on the acquired first relationship, and creates a dispatch plan including the identified control content.

[0009] The creation unit may identify a first predicted value that achieves the target power generation amount, and identify the control content that corresponds to the identified first predicted value in the first relationship as the control content of the energy resource group that achieves the target power generation amount.

[0010] The creation unit may derive a second relationship, which is a relationship between a second predicted value, which is a predicted value of an amount of power generation of an energy resource included in the energy resource group, and a control content of the energy resource at the time of the second predicted value, based on the first relationship, derive the second predicted value that achieves the target amount of power generation, and create the dispatch plan including control content corresponding to the derived second predicted value in the second relationship.

[0011] The creation unit may obtain, from the control contents in the first relationship, a control content having the smallest number of energy resources that cause power generation, obtain the first predicted value corresponding to the obtained control content, and derive the second relationship by allocating the obtained first predicted value to the energy resources that cause power generation according to the obtained control content.

[0012] The acquisition unit may acquire the first relationship based on implementation information of each of a plurality of dispatch plans implemented in the past, each of which includes control contents of the energy resource group included in the dispatch plan and power generation amounts of the energy resource group measured when the dispatch plan is implemented.

[0013] The implementation information may further include implementation conditions of the dispatch plan, and the acquisition unit may acquire the first relationship by generating a prediction model for each control content, which takes the implementation conditions of the dispatch plan as input and outputs a predicted value of the power generation amount of the energy resource group based on the implementation information, and inputting the implementation conditions of the newly created dispatch plan into each of the generated prediction models to obtain the predicted value as the first predicted value.

[0014] Further, a program according to the present invention causes a computer to function as the dispatch plan creating device. Effect of the Invention

[0015] According to the present invention, it is possible to generate a highly accurate dispatch plan. [Brief description of the drawings]

[0016] [Figure 1] FIG. 1 is a configuration diagram of a dispatch plan creation device according to an embodiment of the present invention. [Diagram 2] FIG. 2 is a block diagram of a portion that executes the processing of the dispatch plan creation device of FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0017] Hereinafter, an outline of the embodiment of the present invention will be described, and then a specific configuration of the embodiment will be described.

[0018] In this embodiment, we consider an energy resource group in which the power generation amount of the entire energy resource group has been measured, but the power generation amount of each energy resource in the energy resource group has not been measured. Even for such an energy resource group, if a dispatch plan in which the power generation capacity of the energy resource group is partially utilized has been implemented in the past, the power generation amount when the same dispatch plan is implemented can be predicted by using the information of the power generation amount measured at that time. Moreover, being able to predict the power generation amount in a dispatch plan in which only a part of the power generation capacity of the energy resource group is utilized means that a dispatch plan in which only a part of the power generation capacity of the energy resource group is utilized, that is, a dispatch plan in which a demand response is activated for only a part of the energy resources, can be a candidate for a dispatch plan to be created next.

[0019] The dispatch plan creation device 10 according to the present embodiment shown in FIG. 1 is configured to create a dispatch plan targeting an energy resource group A and an energy resource group B. The energy resource group A includes energy resources A1 to A3. The energy resource group B includes energy resources B1 to B2. Here, the energy resources A1 to A3 and B1 to B2 are each assumed to be air conditioning equipment. When a demand response is activated, each of the energy resources A1 to A3 and B1 to B2 creates a power saving amount, that is, generates negawatts. The amount of power generation below is an amount in which the amount of power saving, that is, the amount of negawatts, is taken as a positive value. The number of energy resource groups, the type and number of specific devices of the energy resources constituting the energy resource group, and the like are arbitrary. The energy resource may be a generator, etc. Hereinafter, the energy resource group and the energy resource are also simply referred to as a resource group and a resource, respectively.

[0020] The resources A1 to A3 are controlled by a resource control system 101. The resources B1 and B2 are controlled by a resource control system 102. The resource control systems 101 and 102 are composed of various control systems and are configured to be able to communicate with the dispatch plan creation device 10 via a communication network NW. The resource control systems 101 and 102 receive a dispatch plan created by the dispatch plan creation device 10 via the communication network NW, and control the resources A1 to A3 or B1 to B2 in accordance with the received dispatch plan. This triggers a demand response.

[0021] The dispatch plan includes control setting values ​​that are set individually for each of the resources A1 to A3 and B1 to B2. More specifically, the dispatch plan includes a combination of each ID of the resources A1 to A3 and B1 to B2 and each control setting value that is associated with each ID. The control setting values ​​set for the resources A1, A3, B1, and B2 are assumed to take one of two values: a value (e.g., "1") that specifies the activation of a demand response (hereinafter also referred to as DR activation), i.e., the power generation of negawatts, and a value (e.g., "0") that specifies the non-activation of DR, i.e., the non-power generation of negawatts. The control setting value set for the resource A2 is assumed to take one of the numerical values ​​of the set temperature. In this example, the control setting value when DR is not activated is 24.0°C, and the control setting value when DR is activated is a numerical value (e.g., 25.5°C) that is within the range of 24.1°C to 28.0°C and has one decimal place. The resource control system 101 sets control setting values ​​of the dispatch plan for each of the resources A1 to A3, and the resource control system 102 sets control setting values ​​of the dispatch plan for each of the resources B1 to B2. The resources A1 to A3 and B1 to B2 each operate according to the control setting values. The control setting values ​​set for each of the resources A1 to A3 are also collectively referred to as the control content A of the resource group A. Similarly, the control setting values ​​set for each of the resources B1 to B2 are also collectively referred to as the control content B of the resource group B.

[0022] An instruction to create a dispatch plan is input from a creation instruction device 110 such as a computer to the dispatch plan creation device 10 via a communication network NW or the like. The creation instruction device 110 takes a command value input from an electric utility (not shown) as a target power generation amount and generates an instruction to create a dispatch plan based on the target power generation amount. The dispatch plan creation device 10 creates a dispatch plan based on the creation instruction from the creation instruction device 110. The details of the creation instruction will be described later.

[0023] The dispatch plan creation device 10 is composed of a server computer managed by an aggregator, etc. The dispatch plan creation device 10 includes a processor 11 such as a CPU (Central Processing Unit), a storage device 12 that stores programs, data, etc., a RAM (Random Access Memory) 13 that functions as a main memory for the processor 11, and a communication module 14 such as a network card connected to a communication network NW.

[0024] The processor 11 executes a program stored in the storage device 12, and uses the data stored in the storage device 12 to operate as an acquisition unit 11A and a creation unit 11B (FIG. 2) described below.

[0025] The storage device 12 stores implementation information, which is information collected when dispatch plans were executed in the past. The implementation information is collected by any method. The implementation information is collected separately for each of the resource groups A and B for each dispatch plan. Specifically, the implementation information for resource group A includes information when resources A1 to A3 are controlled with the control setting value of control content A in the dispatch plan. The implementation information for resource group B includes information when resources B1 to B2 are controlled with the control setting value of control content B in the dispatch plan.

[0026] The implementation information of resource group A includes, for example, the following information: Control content A included in the executed dispatch plan (i.e., the combination of control settings for each resource A1 to A3) The power generation amount (also called total power generation amount) of resource group A measured when the dispatch plan was implemented Execution conditions of the executed dispatch plan. The conditions include various information that may affect the amount of power generation, such as the execution date and time (particularly, the date and time that affect the temperature), holiday information of resource group A (for example, information on whether the execution date is an operating day or a non-operating day), and the typical outside air temperature of resource group A when the dispatch plan is executed.

[0027] The implementation information of resource group B also includes information similar to that of resource group A (just replace "A" in the above information with "B").

[0028] As described above, the processor 11 operates as the acquisition unit 11A and the creation unit 11B shown in Fig. 2. The acquisition unit 11A includes an implementation information extraction unit 11AA, a machine learning unit 11AB, and a power generation amount prediction unit 11AC.

[0029] The implementation information extraction unit 11AA extracts, as learning data, implementation information having common control contents for resource group A or B from among the implementation information of many dispatch plans stored in the storage device 12. The extracted learning data is supplied to the machine learning unit 11AB. The machine learning unit 11AB performs machine learning based on the supplied multiple learning data (particularly, common control contents and the total power generation amount and implementation conditions for the resource group targeted by the control contents). Note that, when the control setting value included in the control contents takes a continuous value like the control setting value for resource A2, the implementation information having common control contents may include implementation information including control contents including a control setting value taking a numerical value within a preset range. The machine learning unit 11AB performs machine learning using the total power generation amount of the learning data as the objective variable (correct answer data) and the implementation conditions of the dispatch plan as explanatory variables. As a result, a power generation prediction model is generated in which the implementation conditions such as the implementation date and time and the outside air temperature are input and the predicted value of the total power generation amount of the resource group is output. The prediction model is generated separately for each resource group and each control content. Each prediction model may output a predicted value obtained by averaging the power generation amounts measured when a dispatch plan with the same control content is executed. When averaging, each power generation amount may be weighted. Each prediction model (prediction parameters, etc.) is stored in the storage device 12 together with information on the control content related to the prediction model.

[0030] The power generation amount prediction unit 11AC receives, via the communication module 14 (FIG. 1), a dispatch plan creation instruction transmitted from the creation instruction device 110 via the communication network NW. The dispatch plan creation instruction includes a command value from the electric utility, i.e., the amount of power saving to be achieved by the dispatch plan, and an implementation condition for the dispatch plan. The implementation condition includes external factors that affect the power generation amount, such as the implementation date and time of the dispatch plan and the predicted outside air temperature (such as the temperature in the respective areas of resource groups A and B based on the weather forecast) at the implementation date and time. The implementation condition is input from the electric utility together with the command value, or is acquired by the creation instruction device 110 in an arbitrary manner separately from the command value.

[0031] The power generation prediction unit 11AC reads out each prediction model stored in the storage device 12 together with information on the control content related to the prediction model. The power generation prediction unit 11AC inputs the implementation conditions included in the instruction to create a dispatch plan to each prediction model, and obtains a predicted value of the total power generation (power saving amount) which is the output from each prediction model. As a result, the total power generation is predicted for each control content for each resource group. The power generation prediction unit 11AC can obtain a relationship between the control content and the predicted value of the total power generation for each of the resource groups A and B from the predicted value from each prediction model and the control content related to each prediction model. Here, it is assumed that the relationship obtained is that shown in the following Table 1 (table for energy resource group A) and Table 2 (table for energy resource group B). [Table 1] [Table 2]

[0032] The power generation amount prediction unit 11AC outputs the obtained relationship and the command value included in the command to create the dispatch plan to the creation unit 11B.

[0033] The creation unit 11B sets the command value as the target power generation amount to be achieved in the dispatch plan, and specifies the control contents of the resource groups A and B that achieve the target power generation amount based on the above relationship, and creates a dispatch plan including the specified control contents. Specifically, the creation unit 11B specifies a combination of predicted values ​​in which the sum of the predicted values ​​of the resource groups A and B matches the target power generation amount. This specification is performed, for example, by formulating a dispatch plan problem as an optimization problem and solving it using a corresponding optimization technique. This specification may be performed by other methods. For example, after extracting an arbitrary predicted value of the resource group A, a process of searching for a predicted value of the resource group B that matches the value obtained by subtracting the predicted value from the target power generation may be repeated to specify the combination of predicted values. A combination of predicted values ​​that achieves the target power generation amount may be searched for by any method, and the first combination found may be the target of this specification.

[0034] For example, if the current target power generation amount is 160 kWh, the combination of the predicted values ​​that matches the target power generation amount and its total is a combination of the predicted value of resource group A=60 kWh and the predicted value of resource group B=100 kWh. In the above relationship, the creation unit 11B creates a dispatch plan for the entire resource groups A and B by combining the control content A (control setting values ​​of resources A1 to A3=1, 26.0°C, 0) corresponding to the predicted value=60 kWh and the control content B (control setting values ​​of resources B1 to B2=1, 1) corresponding to the predicted value=100 kWh. As a result, a suitable dispatch plan in which the target power generation amount=the sum of the predicted values ​​is created.

[0035] Here, the command value is set to the target power generation amount, and the achievement of the target power generation amount is set to the sum of the predicted values, but the target power generation amount may be set to a numerical range having a certain width, and the achievement of the target power generation amount may be set to the sum of the predicted values ​​being within the range of the target power generation amount. In this case, the target power generation amount may be set to a range of the command value ± a predetermined power generation amount, or a range from the command value to a power generation amount exceeding a predetermined power generation amount. In such a case, the creation unit 11B may set the target power generation amount based on the command value, identify a combination of predicted values ​​whose sum of the respective predicted values ​​of the resource groups A and B is within the range of the target power generation amount, and identify the control contents of the resource groups A and B that achieve the target power generation amount.

[0036] The dispatch plan may be created for each unit time slot, and the dispatch plans for each unit time slot may be combined to create an overall dispatch plan. In this case, for example, each piece of information included in the instruction to create a dispatch plan may also be divided into information for each unit time slot.

[0037] The creation unit 11B transmits the created dispatch plan to the resource control system 101 that controls the operation of the resource group A and the resource control system 102 that controls the operation of the resource group B via the communication module 14 and the communication network NW. In particular, of the dispatch plan, the control content A is supplied to the resource control system 101 that controls the resource group A, and the control content B is supplied to the resource control system 102 that controls the resource group B. Thereby, the dispatch plan is executed thereafter.

[0038] As described above, in this embodiment, the acquisition unit 11A acquires, for each of the resource groups A and B, a relationship (hereinafter also referred to as a first relationship) between the control content of the resource group, which may have content for exerting a part of the power generation capacity of the resource group (including the ability to generate negawatts), and the predicted value (hereinafter also referred to as a first predicted value) of the power generation amount of the resource group when the control content is adopted. Then, the creation unit 11B specifies the control content A and B that achieves the target power generation amount based on the first relationship for each of the resource groups A and B acquired by the acquisition unit 11A, and creates a dispatch plan including the specified control content A and B. Therefore, since the resource group can be controlled with the control content that may have content for exerting a part of the power generation capacity of the resource group, it is possible to accurately generate a dispatch plan for the resource groups A and B, for which the power generation amount of each individual resource has not been measured. For example, in the conventional method of creating a dispatch plan for each resource group, assuming that all resources belonging to that resource group can be in only two states, either generating power or not generating power, the power generation amount when resource group A and resource group B are both made to generate power is the predicted power generation value closest to the target power generation amount (200 kWh), and the target power generation amount cannot be achieved, or the target power generation amount can be achieved but is far from the command value. For this reason, the conventional method cannot create a dispatch plan with high accuracy (for example, the target power generation amount can be achieved, or the target power generation amount can be achieved and is close to the command value).

[0039] The method in which the creation unit 11B identifies the control contents A and B that achieve the target power generation amount based on the first relationship and creates a dispatch plan including the identified control contents A and B is not limited to this embodiment and is arbitrary. As an example, as in this embodiment, the creation unit 11B is configured to identify a combination of first predicted values ​​that achieve the target power generation amount from among the first predicted values ​​included in the above relationship, and to identify control contents that correspond to the first predicted values ​​included in the identified combination in each first relationship from the above relationship. The creation unit 11B is configured to create a dispatch plan including the identified control contents as control contents A and B of resource groups A and B that achieve the target power generation amount. This makes it easy to generate a dispatch plan with high accuracy.

[0040] Furthermore, according to this embodiment, the acquiring unit 11A acquires the first relationship for each resource group based on the implementation information of a plurality of dispatch plans executed in the past, each of which includes the control contents A and B of the resource groups A and B included in the dispatch plan and the total power generation amount of the resource groups A and B measured when the dispatch plan was executed. As a result, the first relationship is acquired based on the past dispatch plans, and therefore it is possible to create a dispatch plan with high accuracy.

[0041] Furthermore, in this embodiment, the implementation information further includes the implementation conditions of the dispatch plan, and the acquisition unit 11A generates a prediction model for each resource group and each of the control contents, which inputs the implementation conditions of the dispatch plan and outputs a predicted value of the power generation amount based on the implementation information. Furthermore, the acquisition unit 11A inputs the implementation conditions of the newly created dispatch plan into each of the generated prediction models and obtains the predicted value as a first predicted value, thereby acquiring the first relationship. This makes it possible to create a highly accurate dispatch plan even if the power generation amount of the resource changes depending on the implementation conditions such as the outside air temperature. When the resource is a lighting device or the like that can generate a relatively stable power generation amount without being influenced by the implementation conditions, the implementation information does not need to include the implementation conditions. In this case, a constant predicted value may be obtained for each resource group and control content without requiring a prediction model.

[0042] For example, when the predicted values ​​of the individual power generation amounts of resources B1 and B2 of resource group B are known, the first relationship may be acquired only for resource group A. In such a case, the creation unit 11B identifies control content A that achieves the target power generation amount based on the first relationship acquired by the acquisition unit 11A, and creates a dispatch plan including the identified control content A. A prediction model and the like are also generated only for resource group A. The creation unit 11B may identify control content B that achieves the target power generation amount based on separate individual predicted values, and may include the identified control content B in the dispatch plan. Even in such a case, an accurate dispatch plan is created.

[0043] As another example of the method of creating the dispatch plan, the creation unit 11B may derive a relationship (hereinafter also referred to as the second relationship) between the predicted value of the power generation amount for each resource of the resource groups A and B and the control content of the resource at the second predicted value based on the first relationship (see Tables 1 and 2) between the control content and the predicted value of the total power generation amount. The second relationship may be derived only for an arbitrary resource. The creation unit 11B may derive a second predicted value (one second predicted value or multiple second predicted values) that achieves the target power generation amount, and create a dispatch plan including the control content corresponding to the derived second predicted value in the second relationship. Such creation of the dispatch plan is performed in addition to or instead of the above-mentioned method described as the creation method of the dispatch plan of this embodiment. In addition, for example, the creation unit 11B creates such a dispatch plan when the target power generation amount cannot be achieved with the first predicted value. The creation unit 11B may identify a first predicted value and a second predicted value that can achieve the target power generation amount, and create a dispatch plan that includes control contents for a resource group (e.g., resource group A) that corresponds to the first predicted value in the first relationship, and control contents for a resource (e.g., resource B1 or B2) that corresponds to the second predicted value in the second relationship.

[0044] As an example, the creation unit 11B may obtain the control content with the smallest number of resources that generate power from among multiple types of control content for the same resource group, obtain a first predicted value corresponding to the obtained control content from the above-mentioned first relationship, and obtain a second predicted value by apportioning the obtained first predicted value to the resources that generate power according to the obtained control content. For the purpose of apportionment, the smallest number of resources may be assumed to be 2 or more (because when the number is 1, the amount of power generated by that resource is equal to the first predicted value).

[0045] For the above allocation, it is first necessary to identify the dispatch plan (more specifically, the control content) to be allocated. The creation unit 11B first extracts all the implementation information of the control content with the same content from the implementation information of the dispatch plan stored in the storage device 12. The control content with the same content may include a control content including a control setting value with a numerical value within a preset range when the control setting value is a continuous value like the control setting value for the resource A2. For example, a control content including a control setting value equal to or greater than a predetermined value is extracted as the control content with the same content (because it is considered that the power generation is stronger than that at the predetermined value). The above extraction is performed for each of the control contents. The creation unit 11B extracts the control content with the smallest number of resources to be activated among the extracted control contents, whose number (counted as 1 per unit time; hereinafter, simply referred to as the number of data) is equal to or greater than a predetermined threshold value set in advance. If there are multiple dispatch plans at this point, the one with the largest number of data is extracted. If there are multiple control contents at this point, one is extracted in a method such as a list order, a registration order, or a random order. The control content that is the last remaining control content that has been extracted is set as the control content to be allocated.

[0046] When obtaining a predicted value of the power generation amount when DR is activated for resource A1 of resource group A, control content A in which only resources A1 and A2 in Table 1 are subject to DR activation and control content A in which all resources A1 to A3 are subject to DR activation are extracted as candidates for the control content of the allocation source. In this case, when the control content that minimizes the number of energy resources to activate DR is extracted, the former control content A becomes the control content of the allocation source. Note that the relationship as shown in Table 1 or Table 2 may be used to specify the control content of the allocation source (especially when the predetermined threshold value is 1). For example, the creation unit 11B may refer to the relationship and specify the control content A in Table 1, which is the control content that activates DR for resource A1 and is the control content that only resources A1 and A2, which have the fewest resources to activate DR, as the control content of the allocation source.

[0047] The creation unit 11B refers to the above first relationship, obtains a first predicted value (total power generation amount of the resource group) corresponding to the control content that matches or is closest to the control content of the apportionment source, and based on the first predicted value, predicts the power generation amount of the resource that is DR-activated with the control content of the resource group targeted by the control content of the apportionment source (this predicted value can also be said to be the total power generation amount of the resource group when only that resource in the resource group is DR-activated). For example, the second predicted value to be derived is the product of the value obtained by dividing the number of resources in the resource group to be derived by the number of resources that are DR-activated (generate power) with the control content of the apportionment source, and the first predicted value corresponding to the control content of the apportionment source. The number of resources is not necessarily 1. For example, for a resource with a control setting value that takes continuous values such as the control setting value of resource A2, the number of resources is calculated as (control setting value of the control content of the apportionment source - control setting value when DR is not activated) ÷ (the control setting value that can be taken as the control setting value when DR is activated and is the farthest from the control setting value when DR is not activated - control setting value when DR is not activated). Further, when the control setting value of the extracted control content is different from the control setting value of the control content of the above relationship, the number of resources may be the value obtained above multiplied by the value calculated as the control setting value of the extracted control content ÷ the control setting value of the control content of the above relationship.

[0048] When the control content A in which only resources A1 and A2 in Table 1 above are the targets of DR activation is used as the control content of the apportionment source, since resource A1 can only take the control setting values of two states, DR activation or DR non-activation, the number of resources is "1". The control setting value of resource A2 is 24.0 °C when DR is not activated, and becomes a numerical value with one decimal place between 24.1 °C and 28.0 °C when DR is activated. Since the control setting value is set to 26.0 °C in the control content of the apportionment source, (26.0 - 24.0) ÷ (28.0 - 24.0) = 0.5, so the number of resources of resource A2 is 0.5. The second predicted value, which is the predicted value of the power generation amount of resource A1, is 1 ÷ 1.5 × 60 kWh = 40 kWh.

[0049] Using this method, the creation unit 11B obtains the second predicted value of each resource, and based on at least the second predicted value and the first predicted value, derives a combination of predicted values ​​(a combination including both the first predicted value and the second predicted value or including only the second predicted value) that achieves the target power generation amount, and creates a dispatch plan that includes control contents corresponding to the predicted values ​​included in the derived combination.

[0050] For example, assuming that the target power generation amount is 140 kWh and the relationship between the control contents and the predicted values ​​is as shown in Tables 1 and 2, when DR is invoked only for resources A1, B1, and B2, the predicted value of the total power generation amount of resource group A is 40 kWh, and the predicted value of the total power generation amount of resource group B is 100 kWh, and the sum of these is 140 kWh, so the target power generation amount is achieved. Therefore, the creation unit 11B creates a dispatch plan that invokes DR only for resources A1, B1, and B2.

[0051] The above-described method also enables creation of a highly accurate dispatch plan. This method is particularly effective when the amounts of power generated by each resource in the same resource group are approximately the same.

[0052] Any hardware configuration may be used for the dispatch plan creation device 10. For example, at least a part of each of the acquisition unit 11A and the creation unit 11B may be realized by an ASIC, an FPGA, or the like.

[0053] The created and executed dispatch plan may be stored in the storage device 12 as execution information together with the total power generation amount of each resource group at that time and the execution conditions.

For example, the present invention includes various modifications to the above embodiments and modifications that can be understood by a person skilled in the art within the scope of the technical concept of the present invention. The configurations listed in the above embodiments and modifications can be appropriately combined within a range without contradiction. Also, the omission of each configuration is optional.
