Description

Electric power transaction adjustment device, electric power transaction adjustment system and electric power transaction adjustment method

The present invention relates to an electric power transaction coordinator, an electric power transaction adjustment system, and an electric power transaction adjustment method for adjusting a planned value of electric power traded by a bilateral contract.

Electric power companies such as electric power retailers and power generation companies need to submit a plan for the supply and demand of electric power to the OCCTO (hereinafter referred to as the OCCTO). Based on these plans, the OCCTO manages the free capacity of the interconnection line connecting the areas controlled by each electric power company. The plans to be submitted to the OCCTO include the next-day plan, which indicates the next-day plan, and the same-day plan, which indicates the current-day plan. The deadline for submitting the next-day plan is 12:00 on the day before the day when the actual supply and demand occurs, and the deadline for submitting the same-day plan is one hour before the start time of the time zone in units of 30 minutes. The deadline for submitting the same-day plan is called gate closing.

Electricity consumed by consumers may fluctuate from the time the next day plan is formulated. Patent Document 1 discloses an electric power retail system that adjusts a supply and demand plan so as to cope with unexpected fluctuations in demand. The electricity retail system described in Patent Document 1 modifies the power generation plan created on the previous day according to the amount of electricity demand and the amount of power generation on the day, and notifies the power generation company.

JP-A-2002-123578

As a contract related to electricity trading, there is a bilateral contract in which the electric power company makes a one-to-one contract between the parties. In a bilateral contract, the planned value of the amount of electricity exchanged is adjusted between the parties. For example, since a business operator who has concluded a bilateral contract needs to submit a plan for the next day to a wide-area organization, the plan value for the next day is once decided by agreement between the parties by 12:00. There is a problem that a business operator who has concluded a bilateral contract needs to make manual adjustments such as by telephone between the parties each time when changing the planned value once fixed, which is troublesome.

In the technique described in Patent Document 1, the electric power retailer who owns the electric power retail system unilaterally modifies the power generation plan and notifies the power generation company. It is not possible to adjust the planned value agreed between the parties to the bilateral contract. For example, even if the electric power retailer tries to change the planned value in the next day plan, the power generation company may not tolerate the change. Further, with the technique described in Patent Document 1, the power generation company cannot change the planned value. As described above, the technology described in Patent Document 1 has not been changed so as to be acceptable to both business operators who have concluded a bilateral contract. Therefore, the technology described in Patent Document 1 is used to conclude a bilateral contract. It cannot be applied to the adjustment of the planned value after submitting the next day plan of the business operator.

The present invention has been made in view of the above, and obtains an electric power transaction adjusting device capable of adjusting a planned value of supply and demand of a business operator who has concluded a bilateral contract while suppressing labor. The purpose is.

In order to solve the above-mentioned problems and achieve the object, the electric power transaction coordinator according to the present invention is supplied based on the bilateral contract for each bilateral contract regarding the power supply concluded between the two business operators. It is provided with a storage unit for storing adjustment condition information indicating adjustment conditions for making adjustments for changing the planned value of electric power from a provisionally fixed value agreed between the two business operators. Further, the electric power transaction coordinator receives a plan adjustment request indicating that one of the two companies requests adjustment for changing the plan value from the tentative fixed value, and the received plan adjustment request. It is provided with a plan adjustment unit that performs adjustment processing for determining a bilateral contract to be adjusted for the plan value and an adjustment amount that is an amount for changing the plan value based on the adjustment condition information. The plan adjustment request includes a desired adjustment amount indicating the amount of change in the planned value desired by one business operator.

The electric power transaction adjusting device according to the present invention has the effect of suppressing labor and adjusting the planned value of the supply and demand amount of the business operator who has concluded a bilateral contract.

Hereinafter, the electric power transaction adjustment device, the electric power transaction adjustment system, and the electric power transaction adjustment method according to the embodiment of the present invention will be described in detail with reference to the drawings. The present invention is not limited to this embodiment.

Embodiment 1.
FIG. 1 is a diagram showing a configuration example of a power transaction adjustment system according to the first embodiment of the present invention. The electric power transaction adjustment system of the present embodiment includes the relative contract adjustment device 1 which is the electric power transaction adjustment device according to the present invention, and the operator devices 2-1 to 2-3 connected to the relative contract adjustment device 1. .. The operator devices 2-1 to 2-3 are devices managed by different electric utilities (hereinafter, also referred to as operators). The operator devices 2-1 to 2-3 have the same configuration, and when the operator devices 2-1 to 2-3 are shown below without distinction, they are referred to as the operator device 2. Although FIG. 1 shows three operator devices 2 connected to the relative contract adjustment device 1, the number of operator devices 2 connected to the relative contract adjustment device 1 is shown in the example shown in FIG. Not limited.

The bilateral contract adjusting device 1 adjusts the planned value of the electric energy traded by the bilateral contract (hereinafter, also referred to as the planned value of the bilateral contract). The bilateral contract in the present embodiment is a contract relating to the supply of electric power concluded between two business operators. A bilateral contract is a one-to-one contract, and the content of the contract is agreed between the parties, that is, between the business operators. When the business operator participates in the electric power transaction adjustment system of the present embodiment, the business operator connects the business operator device 2 to the relative contract adjustment device 1 and transfers the planned value to the relative contract adjustment device 1 via the business operator device 2. Provide the information necessary for the adjustment of. As a result, the business operator can receive the service of adjusting the planned value of the bilateral contract. The bilateral contract adjustment device 1 may be a device jointly managed by a plurality of electric power companies, a device managed by a third party other than the electric power company, or a specific electric power business. It may be a device managed by a person. The process of adjusting the planned value of the bilateral contract will be described later.

The business operator device 2-1 is connected to the supply and demand management system 3-1 and the business operator device 2-2 is connected to the supply and demand management system 3-2. The supply and demand management system 3-1 is managed by the business operator who manages the business operator equipment 2-1 and the supply and demand management system 3-2 is managed by the business operator who manages the business operator equipment 2-2. The supply and demand management system 3-1 and 3-2 manages at least one of the supply and demand amount of the equipment managed by the corresponding business operator, for example, the power demand amount and the power generation amount. The supply and demand management systems 3-1 and 3-2 may have different configurations and functions. For example, when the business operator that manages the supply and demand management system 3-1 is an electric power retailer, the supply and demand management system 3-1 manages the demand amount of the consumer who has a contract with the business operator. If the business operator that manages the supply and demand management system 3-1 is an electric power retailer, and this electric power retailer has a generator, the supply and demand management system 3-1 is further based on the generator. Manage the amount of power generation. When the business operator that manages the supply and demand management system 3-2 is a power generation business operator, the supply and demand management system 3-2 manages the amount of power generated by the generator.

The supply and demand management system 3-1 and 3-2 generate a supply and demand plan based on the managed supply and demand amount and transmit it to the OCCTO system 4. The OCCTO system 4 is a system managed by the OCCTO, which accepts submissions of supply and demand plans from business operators and manages the supply and demand plans of each business operator. Specifically, the supply and demand plan submitted by the OCCTO to the OCCTO includes a next-day plan showing the next-day plan and a same-day plan showing the current-day plan. In these plans, the planned value of the supply and demand amount for each time zone with 30 minutes as one frame is shown. The deadline for submitting the next-day plan is 12:00 on the day before the day when the actual supply and demand occurs, and the deadline for submitting the same-day plan is one hour before the start time of the time zone in units of 30 minutes. In the next day plan, the planned value for one day of the next day, that is, for 48 frames is shown. In addition, these submission deadlines are shown as an example of the values currently set in Japan, and the submission deadline for each plan is not limited to this example, for example, even if the above-mentioned submission deadline is changed in the future. The electric power trading adjustment system of the present embodiment can perform the same processing by using the changed deadline.

Further, in the present embodiment, an example in which a wide-area organization manages the plans of each business operator will be described, but even if the plans of each business operator are managed by another organization, country, business operator, etc. instead of the wide-area organization. Good. In this case, instead of the wide area organization system 4, a plan management system that manages the plans of each business operator is used. Further, although the example in which the electric power transaction adjustment system is operated in Japan will be described here, the electric power transaction adjustment system of the present embodiment may be operated in a country other than Japan. When the electric power transaction coordination system of the present embodiment is operated in another country, a management system that manages the plans of the operator is used in each country in the same manner as the OCCTO system 4 instead of the OCCTO system 4. Examples of institutions similar to wide-area institutions include PJM (Pennsylvania-New Jersey-Maryland) in the United States, NGESO (National Grid Electricity System Operator) in the United Kingdom, and POSOCO (POwer System Operation COrporation Limited) in India. Also, as for the deadline for submitting each plan, the deadline set by each management system may be used.

In the example shown in FIG. 1, the operator devices 2-1 and 2-2 are connected to the supply and demand management system 3-1 and 3-2, respectively, and the operator devices 2-3 are not connected to the supply and demand management system. As described above, the relative contract adjusting device 1 of the present embodiment has a planned value of the relative contract not only for the business operator having the supply and demand management system but also for the business operator not having the supply and demand management system. Coordination services can be provided. Hereinafter, when the supply and demand management systems 3-1 and 3-2 are shown without distinction, they are referred to as the supply and demand management system 3. The number of business devices 2 connected to the supply and demand management system 3 and the number of business devices 2 not connected to the supply and demand management system 3 are not limited to the example shown in FIG.

As described above, the business operators participating in the electric power transaction adjustment system of the present embodiment have concluded bilateral contracts with other business operators. The business operator who concludes a bilateral contract needs to submit the next-day plan and the same-day plan to the wide-area organization, and also needs to agree the plan value in each plan with the business partner of the contract. For this reason, the business operator cannot freely change the planned value even if the demand amount or the amount of power generation changes from the previous day's forecast and wants to change the planned value. Conventionally, for example, a business operator who has concluded a bilateral contract adjusts the planned value by the following procedure. First, both companies that have concluded a bilateral contract once agreed and finalized the plan value for the next day by 12 o'clock, and each reflected the agreed plan value to the OCCTO. Submit the plan the next day. After that, when it becomes necessary to change the planned value, the business operator adjusts the planned value manually between the parties by telephone or the like each time, and sends the same-day plan reflecting the adjusted planned value to the OCCTO. I am submitting. In this way, conventionally, it has been troublesome to change the agreed planned value. Manual adjustment will take time and effort not only for the business operator requesting the change but also for the business operator of the contract partner. In particular, a business operator who has concluded a bilateral contract with a plurality of business operators will make the above adjustment for each contract, and it is difficult to flexibly change the planned value according to the situation on the day.

In the present embodiment, conditions for adjustment are registered in advance in the bilateral contract adjustment device 1 for each bilateral contract, and the bilateral contract adjustment device 1 plans after submitting the next day plan based on the adjustment conditions. The value is adjusted automatically. As a result, it is possible to reduce the labor and adjust the planned value of the supply and demand amount of the business operator who has concluded the bilateral contract.

Next, a configuration example of the bilateral contract adjustment device 1 and the operator device 2 will be described. As shown in FIG. 1, the relative contract adjustment device 1 includes a communication unit 11, a plan value registration unit 12, an adjustment condition registration unit 13, a storage unit 14, a check result reflection unit 15, a plan adjustment unit 16, and a transaction monitoring unit 17. The result output unit 18 and the wide area machine-related section 19 are provided.

The communication unit 11 communicates with other devices such as the operator device 2. When the planned value registration unit 12 receives the planned value information, which is information indicating the planned value, from the operator device 2 via the communication unit 11, the planned value information is stored in the storage unit 14, and the planned value is stored in the storage unit 14. To register. When the adjustment condition information, which is the information indicating the adjustment condition in the adjustment of the planned value, is received from the operator device 2 via the communication unit 11, the adjustment condition is registered by storing the received adjustment condition information in the storage unit 14. To do.

The storage unit 14 stores contract basic information, planned value information, adjustment condition information, and adjustment amount information. The basic contract information is information related to the contract for each bilateral contract, and the adjustment amount information is information used for adjusting the planned value of the present embodiment. Details of contract basic information, planned value information, adjustment condition information, and adjustment amount information will be described later.

When the check result reflection unit 15 receives the check result from the operator device 2 of the plan checker via the communication unit 11, the check result is reflected in the plan value information of the storage unit 14. The plan adjustment unit 16 receives the plan adjustment request via the communication unit 11, and adjusts the relative contract to be adjusted of the plan value and the amount to change the plan value based on the plan adjustment request and the adjustment condition information. Perform an adjustment process to determine the amount. The plan adjustment request is a request indicating that one of the two businesses that are the parties to the bilateral contract requests adjustment to change the planned value from the provisional fixed value described later. It will be described later. The transaction monitoring unit 17 changes the variable amount of the planned value of the corresponding business operator in order to prevent the planned value from being adjusted by the plan adjusting unit 16 in a loop. The variable amount will be described later. The details of the operations of the check result reflecting unit 15, the planning adjustment unit 16, and the transaction monitoring unit 17 will be described later.

The result output unit 18 outputs the result of adjustment by the plan adjustment unit 16. The method of outputting the adjustment result by the result output unit 18 may be a method of transmitting the adjustment result to the operator device 2 or a method of displaying the adjustment result on the screen. In the former case, the operator device 2 can notify the operator of the adjustment result by displaying the adjustment result on the screen.

The OCCTO-related section 19 reflects the result of the adjustment by the plan adjustment unit 16 in the plan value information, and the plan value information reflecting the adjustment result is changed by the adjustment via the communication unit 11. It is transmitted to the supply and demand management system 3 of the business operator. As a result, the operator device 2 can reflect the adjusted planned value in the same-day plan and transmit the same-day plan reflecting the adjustment to the wide area engine system 4. When the business operator device 2 is connected to the supply and demand management system 3, the transmission to the wide area engine system 4 of the day plan is performed by the supply and demand management system 3. In this case, the operator device 2 transmits the next day result reflecting the adjusted planned value to the wide area engine system 4 via the supply and demand management system 3.

Here, the plan registrant and the plan checker in the bilateral contract will be explained. In a bilateral contract, one of the two businesses that have a bilateral contract is the plan registrant and the other is the plan checker. The plan registrant is a business operator who registers the next day's plan value submitted as the next day plan, and the plan checker is a business operator who checks the registered plan value. In the present embodiment, the planned value is registered by being transmitted from the operator device 2 to the bilateral contract adjustment device 1. The plan checker checks the registered plan value, and if there is a problem with the registered plan value, corrects the plan value after coordinating with the plan registrant. In addition, if there is no problem with the registered plan value, the plan checker approves the plan value without modifying it. The plan checker, for example, uses the business operator device 2 to transmit the corrected amount of the registered plan value to the relative contract adjustment device 1 as a check result. If the registered planned value is approved, the correction amount becomes 0. When the check result reflecting unit 15 of the bilateral contract adjusting device 1 receives the check result from the operator device 2 of the check planner via the communication unit 11, the check result is received in the storage unit 14 in the corresponding plan. Reflect in value information. The method of notifying the check result is not limited to this example.

FIG. 2 is a diagram showing a configuration example of the operator device 2 of the present embodiment. The operator device 2 includes a communication unit 21, a plan creation unit 22, a plan check unit 23, an adjustment condition management unit 24, an adjustment request generation unit 25, and a display unit 26. The communication unit 21 communicates with other devices such as the relative contract adjustment device 1. The planning unit 22 creates a planned value of the supply and demand amount every 30 minutes on the next day, and transmits each planned value every 30 minutes as the planned value information to the bilateral contract adjustment device 1 via the communication unit 21. When the business operator device 2 is connected to the supply and demand management system 3, the planning unit 22 acquires the next day plan from the supply and demand management system 3, and based on the acquired next day plan, the supply and demand every 30 minutes of the next day. You may create a planned value for the quantity. The plan check unit 23 acquires the plan value information indicating the plan value of the other party's business operator from the bilateral contract adjustment device 1 or the business operator device 2 of the other party's business operator of the bilateral contract via the communication unit 21. Check the planned value of the other company. The processing of the plan creation unit 22 is performed when the business operator who manages the business operator device 2 including the plan creation unit 22 is the plan creator, and the processing of the plan check unit 23 is performed by the business operator including the plan check unit 23. This is performed when the business operator who manages the device 2 is a plan checker.

The adjustment condition management unit 24 determines the adjustment conditions when the business operator that manages the business operator device 2 including the plan check unit 23 is a fluctuation absorber, and transmits the determined adjustment conditions to the relative contract adjustment device 1. It is transmitted via 11. Fluctuation absorbers and adjustment conditions will be described later. The adjustment request generation unit 25 creates a plan adjustment request for requesting a change in the plan value when the plan value is changed after the deadline for submitting the plan the next day, and sends the relative contract adjustment device 1 to the relative contract adjustment device 1 via the communication unit 21. Send. The details of the plan adjustment request will be described later. The display unit 26 displays on the screen the plan value information created by the plan creation unit 22, the plan value information registered by the contractor, the adjustment result received from the relative contract adjustment device 1, and the like.

Although FIG. 2 has described an example in which the business operator device 2 includes a plan check unit 23 that checks the planned value, the bilateral contract adjustment device 1 may include a plan check unit that checks the planned value. Good. In this case, for example, each business operator logs in to the bilateral contract adjustment device 1 using the business operator device 2 to access and instruct the execution of the plan check, so that the bilateral contract adjustment device 1 is the other business operator. Executes the planned value information registered by. In this case, the planned value information stored in the relative contract adjusting device 1 is configured so that only the planned value information corresponding to this relative contract can be viewed and edited for each relative contract among the planned value information. Will be done.

In the above example, one of the businesses that have concluded the bilateral contract was the plan registrant and the other was the plan checker, but between the businesses that conclude the bilateral contract by the deadline for submitting the plan the next day. The method is not limited to this example as long as the planned value is agreed.

Next, the hardware of each device constituting the power transaction adjustment system of the present embodiment will be described. In the bilateral contract adjustment device 1 of the present embodiment, the computer system is executed by the power transaction adjustment program, which is a program in which the processing in the bilateral contract adjustment device 1 is described, on the computer system.

Next, the operation of the electric power transaction adjustment system of the present embodiment will be described. First, the period during which each process is performed in the present embodiment will be described. FIG. 4 is a diagram showing the relationship between each process and the period implemented in the electric power transaction adjustment system of the present embodiment. In FIG. 4, the day when supply and demand actually occurs is set as the current day, and the day before the day is shown as the previous day. As described above, each business operator needs to submit a plan for supply and demand of the next day, that is, the day corresponding to the day in FIG. 4, to the OCCTO as the next day plan on the previous day. In the example shown in FIG. 4, the next day plan submission deadline, which is the final submission deadline for the next day plan, is 12:00 on the previous day. The next day plan submission deadline is the deadline that all businesses should comply with, regardless of whether or not they have a bilateral contract.

In the example shown in FIG. 4, the plan registration deadline is set to one hour before 12:00 the day before the next day plan submission deadline, that is, 11:00 the day before. The plan registration deadline is a deadline set for each bilateral contract. The plan registrant registers the plan value for the next day in the bilateral contract adjustment device 1 by the plan registration deadline. As shown in FIG. 4, the plan registration period during which the plan registrant can register the plan value for the next day is a period before the plan registration deadline. The starting point of the plan registration period can be arbitrarily determined as long as it is before the plan registration deadline. The period from the plan registration deadline to the next day plan submission deadline is the plan check period in which the plan registrant can check the plan.

As described above, in the present embodiment, the bilateral contract adjustment device 1 automatically adjusts the plan value according to the adjustment conditions for each bilateral contract after the next day plan submission deadline. The period during which the planned value can be adjusted by the bilateral contract adjustment device 1 is called an adjustment period. The start point of the adjustment period is the next day plan submission deadline, and the plan adjustment deadline (hereinafter referred to as the adjustment deadline in the figure), which is the end point of the adjustment period, is determined for each bilateral contract. The planning adjustment deadline is set before the gate closes. The gate close is the deadline for submitting the day plan to the OCCTO, and in the example shown in FIG. 4, it is one hour before the start time of the frame to be adjusted (described as the adjustment target frame in FIG. 4). Gate closing is the deadline that all businesses should meet, with or without bilateral contracts. In the present embodiment, during the adjustment period, only the adjustment by the bilateral contract adjustment device 1 is performed, and the planned value cannot be changed by the business operator. Note that FIG. 4 shows an example in which the next day plan submission deadline and gate closing are currently set by the OCCTO, but as described above, these specific times are not limited to this example.

Next, in the electric power transaction adjustment system of the present embodiment, the processing until the provisional determination of the planned value on the next day will be described. In the present embodiment, as described with reference to FIG. 4, the next day's plan value is registered and the plan value is checked by the next day's plan submission deadline. The checked planned value is temporarily determined as the planned value for the next day. This tentatively finalized planned value corresponds to the planned value in the next-day plan submitted to the OCCTO.

FIG. 5 is a chart diagram showing the operation of the electric power transaction adjustment system of the present embodiment until the planned value for the next day is provisionally determined. First, the business operator device 2 of the plan registrant creates a plan for the next day's demand for each bilateral contract (step S1), and uses the planned value for each time zone in the created plan as the plan value information as the bilateral contract adjustment device. It is transmitted to 1 (step S2). As described above, the business operator device 2 connected to the supply and demand management system 3 may acquire the next day plan created by the supply and demand management system 3 and create the next day plan based on the next day plan.

The bilateral contract adjustment device 1 registers the plan value received from the business device 2 of the plan registrant (step S3). Specifically, the bilateral contract adjustment device 1 registers the planned value by storing the planned value information received from the operator device 2 in the storage unit 14. The above steps S1 to S3 are carried out during the plan registration period.

Next, during the plan check period, the plan checker's business device 2 receives the plan value registered by the plan registrant's business device 2 from the bilateral contract adjustment device 1 (step S4). For example, the business device 2 of the plan checker is registered by the business device 2 of the plan registrant by requesting the bilateral contract adjustment device 1 to read the planned value information corresponding to the corresponding business device 2. Receive the planned value. As described above, the business device 2 of the plan checker may receive the plan value from the business device 2 of the plan registrant. Next, the business device 2 of the plan checker checks the planned value registered by the business device 2 of the plan registrant (step S5), and transmits the check result to the relative contract adjustment device 1 (step S6). .. As described above, the business device 2 of the plan checker transmits the correction amount as the check result to the relative contract adjustment device 1 when it is necessary to correct the plan value registered by the business device 2 of the plan registrant. To do. When the bilateral contract adjustment device 1 receives the check result from the operator device 2 of the plan checker, the bilateral contract adjustment device 1 reflects the check result in the plan value information stored in the plan value information (step S7). By the above processing, the planned value for the next day is tentatively determined. In step S7, the planned value after the check result is reflected becomes a tentative final value. As described above, the tentative fixed value is the planned value agreed between the two business operators corresponding to the bilateral contract.

Next, the adjustment process of the planned value performed by the relative contract adjusting device 1 of the present embodiment will be described after the planned value of the next day is tentatively determined. Here, first, the information used for the adjustment process of the planned value will be described. FIG. 6 is a diagram showing an example of basic contract information stored in the storage unit 14 of the relative contract adjustment device 1 of the present embodiment. The contract basic information is one of the information that is the basis of the adjustment amount information described later. The basic contract information is registered by the business operator when the business operator who has concluded the bilateral contract participates in the electric power transaction adjustment system of the present embodiment, or when a new bilateral contract is concluded. For example, the business operator registers the basic contract information by operating the business operator device 2 to transmit the basic contract information from the business operator device 2 to the relative contract adjustment device 1. Since the basic contract information is information agreed between the parties to the bilateral contract, either of the parties to the bilateral contract may register the basic contract information in the bilateral contract coordinating device 1. Further, when the basic contract information once registered is changed by an agreement between the parties, the business operator changes the contents registered in the bilateral contract adjustment device 1 via the business operator device 2.

As shown in FIG. 6, the basic contract information includes information for identifying the contract, an upper limit of the amount of power supplied, a lower limit of the amount of power supplied, a plan registrant, a plan registration deadline, and a plan. It consists of an adjustment deadline. The upper limit value and the lower limit value are the upper limit value and the lower limit value specified in the contract such as annual units, and are used to confirm whether the adjusted value is within these values in the adjustment process of the planned value described later. You may. Here, since the target is a bilateral contract, the information that identifies the contract means the information that identifies the bilateral contract. In FIG. 6, in order to make it easy to understand the business operator subject to the bilateral contract and the direction of power supply, the information for identifying the bilateral contract is the identification information of the supplier business operator-identification of the supply destination business operator. Although it is shown in the form of information, the form of information is not limited to this example. Further, in FIG. 6, the identification information of the business operator is represented by the abbreviation of the business type and the identification character, such as describing the power generation business operator A as the origin A and the retail business operator a as the small a. ing. In the example shown in FIG. 6, at least the power generation companies A, B, C and the retail companies a, b, c, d, e, and f participate in the power transaction adjustment system of the present embodiment. ..

For example, in the example shown in FIG. 6, “departure A-small b” described at the top indicates a bilateral contract in which power is supplied from the power generation company A to the retail company b. In this contract, the power generation company A is set as the plan registrant. Therefore, the retailer b, which is the partner of this bilateral contract, becomes the plan checker. Also, in this contract, the plan registration deadline is set 60 minutes before the submission deadline, that is, the submission deadline for the next day plan. Therefore, assuming that the deadline for submitting the next day plan is 12:00, the deadline for registering the plan is 11:00. Also, in this contract, the planning adjustment deadline is set 60 minutes before the gate close (GC). In the example shown in FIG. 6, the plan registration deadline and the plan adjustment deadline all have the same value, but these are set for each bilateral contract and do not have to be the same value. ..

Since it is not preferable that information on other bilateral contracts can be viewed by anyone other than the parties to the bilateral contract, the bilateral contract adjustment device 1 can view and edit the basic contract information corresponding to each bilateral contract only by the corresponding person at that time. Set the access right of the contract basic information so that it is possible. For example, for each identification information of the business operator device 2, access rights for viewing and editing may be set for each information stored in the storage unit 14, or the business operator may set access rights for viewing and editing via the business operator device 2. It may be configured to log in to the bilateral contract adjustment device 1, and access rights for viewing and editing may be set for each information stored in the storage unit 14 for each login ID (IDentifier) assigned to the business operator. ..

For example, in the example shown in FIG. 6, since the first to third contracts from the top are bilateral contracts in which the power generation company A is a party, the power generation company A has the basic contract information shown in FIG. Of these, the information in area 201 can be viewed and edited.

FIG. 7 is a diagram showing an example of planned value information stored in the storage unit 14 of the relative contract adjustment device 1 of the present embodiment. The planned value information is not used in the planned value adjustment process of the present embodiment, but is used in the coordinated process with the OCCTO. As shown in FIG. 7, the planned value information is composed of information indicating the time zone of each frame for each 30-minute frame and the amount of electric energy supplied within the frame for each bilateral contract. In the example shown in FIG. 7, each time zone is shown in the vertical direction, and the bilateral contract is shown in the horizontal direction. In FIG. 7, as the information for identifying each contract, the abbreviation of the supplier of the supply source-the abbreviation of the operator of the supply destination is shown as in the example shown in FIG. For example, the first bilateral contract from the left of the planned value information shown in FIG. 7 is a contract in which electric power is supplied from the power generation company A to the retail company b.

As described above, the plan value information is tentatively confirmed through registration by the plan registrant and check by the plan checker. The tentatively finalized planned value corresponds to the planned value submitted by each business operator as the next day plan. The procedure before the determined planned value is determined is not limited to the above-mentioned example. For example, by coordinating between the parties to the bilateral contract without defining the plan registrant and the plan checker, the plan value agreed as the next day's plan is determined, and this plan value is used as the plan value information as one of the parties. However, by the next day's plan submission deadline, it may be registered in the bilateral contract adjustment device 1 as tentatively determined plan value information.

The plan value information may be changed by the adjustment process of the plan value by the relative contract adjustment device 1 after it is tentatively determined as the value of the next day by the next day plan submission deadline, but it is a direct change from the business operator. Can't. Further, similarly to the basic contract information, the bilateral contract adjustment device 1 sets the access right of the planned value information so that only the person at that time corresponding to the planned value information corresponding to each bilateral contract can view and edit the planned value information. deep. For example, in the example shown in FIG. 7, since the contracts from the leftmost to the third are bilateral contracts in which the power generation company A is a party, the power generation company A has the planned value information shown in FIG. Of these, the information in area 202 can be viewed and edited.

FIG. 8 is a diagram showing an example of adjustment condition information stored in the storage unit 14 of the relative contract adjustment device 1 of the present embodiment. The adjustment condition information is information indicating the conditions of the adjustment processing of the planned value by the relative contract adjustment device 1 of the present embodiment. The adjustment condition information indicates an adjustment condition for changing the planned value of the amount of electric energy supplied based on the bilateral contract from the provisionally fixed value agreed between the two business operators for each bilateral contract. The adjustment condition information is one of the information that is the basis of the adjustment amount information described later. As shown in FIG. 8, the adjustment condition information includes information for identifying the contract, an adjustment kicker, a fluctuation absorber, an increase price, a decrease price, a decrease variable amount from the next day plan submission value, and the next day. It consists of the variable amount that can be increased from the planned submission value. The information that identifies the contract is the same as the information that identifies the contract in the basic contract information shown in FIG. The increase price, the decrease price, the variable amount of decrease from the value submitted in the next day plan, and the variable amount of increase from the value submitted in the next day plan are information determined by the fluctuation absorber.

The adjustment kicker, which is the first business operator, is a business operator capable of transmitting a plan adjustment request that triggers the start of the adjustment process of the planned value by the relative contract adjustment device 1 of the present embodiment, and concludes a bilateral contract. It is one of the businesses that do. The second operator, the variable absorber, is an operator that absorbs the change in the planned value requested by the adjustment kicker, that is, changes the planned value in response to the request. Of the two businesses that have entered into one bilateral contract, one is the adjustment kicker and the other is the variable absorber. Therefore, if the adjustment kicker is determined for each bilateral contract, the fluctuation absorber will be automatically determined. Businesses that have entered into bilateral contracts agree on which one will be the adjustment kicker.

In a bilateral contract, one company supplies power to the other company, so if either company changes the planned value, the other company also needs to change the planned value. If there is only one bilateral contract, if the adjustment kicker requests a change in the planned value, the only operator that can accept this change is the variable absorber in this bilateral contract. On the other hand, when one business operator concludes a plurality of bilateral contracts, there may be a plurality of business operator candidates whose planned values are changed according to the request of this business operator. That is, when there are multiple bilateral contracts in which one business operator is the adjustment kicker and the other business operator is the fluctuation absorber, multiple other business operators corresponding to the multiple bilateral contracts actually plan. Candidates for businesses that change values. In the present embodiment, the fluctuation absorber determines the increase price, the decrease price, the amount of decrease fluctuation from the next day plan submission value, and the increase fluctuation amount from the next day plan submission value. The contract adjusting device 1 determines the business operator who actually changes the planned value and the adjustment amount which is the amount of electric energy to be changed in consideration of these.

The ascending price and the decreasing price constitute the first price. The first price is the unit price of the amount of electricity to be absorbed when the fluctuation absorber absorbs the change of the planned value requested by the adjustment kicker. That is, the first price is a unit price of electric energy that changes as a result of changing the planned value from a tentative fixed value, and is a unit price that can be accepted by the second business operator. The increase price is the unit price when the change in the planned value requested by the adjustment kicker is a change in the direction of increasing the supply amount, and the decrease price is the change in the plan value requested by the adjustment kicker. This is the unit price when the amount is changed in the direction of lowering.

The lower variable amount from the next day plan submission value (hereinafter referred to as the lower variable amount) is a value indicating the maximum amount of power that the fluctuation absorber can reduce from the tentatively determined next day plan value. .. In the example shown in FIG. 8, since the lower variable amount is the electric energy that can be lowered from the planned value, the positive and negative signs are indicated by negative values. The variable amount of increase from the next day plan submission value (hereinafter referred to as the variable amount of increase) is a value indicating the maximum amount of power that the fluctuation absorber can increase from the tentatively determined next day's planned value. .. In the example shown in FIG. 8, since the increase variable amount is the amount of power that can be increased from the planned value, the positive and negative signs are indicated by positive values. When the downward variable amount and the upward variable amount are shown without distinction, they are referred to as variable amounts. The variable amount indicates the amount of change of the planned value from the provisionally fixed value that can be accepted by the second business operator.

Note that the information on the adjustment kicker and the fluctuation absorber among the adjustment condition information may be registered from the operator device 2 of either the adjustment kicker or the fluctuation absorber. However, for each bilateral contract, it is assumed that the parties have agreed which one will be the adjustment kicker. Further, since the increase price, the decrease price, the decrease variable amount, and the increase variable amount are determined by the fluctuation absorber, they are registered from the operator device 2 of the fluctuation absorber. The adjustment condition information may be set for each frame, that is, for each time zone of 30 minutes, and unless the adjustment condition information is changed, the registered adjustment condition information is used regardless of the frame. It may be in a form in which information is not set. When the adjustment condition information is set for each frame, the information illustrated in FIG. 8 is stored in the storage unit 14 for each time zone. Further, the adjustment condition information may be set in units of a plurality of frames.

Further, similarly to the basic contract information, the bilateral contract adjustment device 1 sets the access right of the adjustment condition information so that only the person at that time corresponding to the adjustment condition information corresponding to each bilateral contract can view and edit the adjustment condition information. deep. However, since the adjustment condition information is information determined by the fluctuation absorber, the access right of the adjustment condition information is set so that only the fluctuation absorber of the corresponding bilateral contract can view and edit it. May be good. For the adjustment kicker, the access right may be set so that only the adjustment condition information regarding the corresponding bilateral contract can be viewed. For example, in the example shown in FIG. 8, since the contracts from the top to the third are bilateral contracts in which the power generation company A is a party, the power generation company A has the adjustment condition information shown in FIG. Of these, the information in area 203 can be viewed and edited.

The fluctuation absorber determines the increase price, the decrease price, the decrease variable amount, and the increase variable amount according to, for example, the capacity of the equipment managed by the variable controller and the supply and demand situation. For example, if the variable absorber is a power generation company and the direction of power supply in the bilateral contract is the direction of supplying power from the power generation company to the retail company, the increased price is obtained as the cost of power generation. Determine in consideration of the desired profit. In addition, if the variable absorber is a power generation company and the direction of power supply in the bilateral contract is the direction of supplying power from the power generation company to the retail company, all the managed generators can generate power. The amount that can be increased and changed is determined according to the difference between the maximum power generation amount, which is the total of the maximum values, and the planned value for the next day. In addition, a business operator who is a variable absorber for multiple bilateral contracts allocates each of the downward variable amount and the upward variable amount to multiple bilateral contracts, so that the downward variable amount and the upward variable amount for each relative contract Determine the possible amount. For example, suppose that a fluctuation absorber, which is a power generation company, determines that it is possible to raise the planned value to a total of 300 kWh in consideration of the maximum power generation amount and the planned value for the next day. Then, it is assumed that this fluctuation absorber is a fluctuation absorber in three bilateral contracts. In this case, the fluctuation absorber may use 100 kWh obtained by dividing 300 kWh by 3 as the increase variable amount of each bilateral contract, or assign different increase variable amounts such as 80 kWh, 100 kWh, and 120 kWh to the three relative contracts, respectively. You may do so.

In addition, if the fluctuation absorber is a power generation company and the direction of power supply in the bilateral contract is the direction of supplying power from the power generation company to the retail company, adjustments are made to lower the planned value. This is equivalent to returning the reduced amount from the tentatively fixed planned value from the retailer to the power generation company. The power generation company will purchase the amount reduced from the fixed planned value, but the power generation company will pay the amount when the planned value decreases, so the reduced price is generally set to a low value. .. In addition, if the variable absorber is a retailer and the direction of power supply in the bilateral contract is the direction of supplying power from the power generation company to the retailer, adjustments are made to raise the planned value. This is equivalent to forcing the retailer to purchase the increase from the tentatively fixed planned value. Therefore, in this case, the reduction price is generally set to a low value. In addition, if the variable absorber is a retailer and the direction of power supply in the bilateral contract is the direction of supplying power from the power generation company to the retailer, adjustments are made to lower the planned value. Then, the power generation company will supply the retailer with a supply amount smaller than the tentatively decided planned value, and the retailer will respond by purchasing insufficient electricity by other means. Therefore, in this case, in general, the increased price is set in consideration of the cost when the retailer procures by another means. The method of determining the increase price, the decrease price, the decrease variable amount, and the increase variable amount is not limited to the above-mentioned example, and the fluctuation absorber can use the increase price, the decrease price, and the decrease variable amount. It is possible to arbitrarily determine the amount of variable increase at your own convenience.

FIG. 9 is a diagram showing an example of adjustment amount information stored in the storage unit 14 of the relative contract adjustment device 1 of the present embodiment. The adjustment amount information is information that is used in the adjustment process of the planned value by the relative contract adjustment device 1 of the present embodiment and is appropriately updated in the process of the adjustment process of the planned value. When the contract basic information and the adjustment condition information are registered, the plan adjustment unit 16 of the relative contract adjustment device 1 generates the adjustment amount information based on the contract basic information and the adjustment condition information and stores it in the storage unit 14. Further, when one or both of the basic contract information and the adjustment condition information is updated, the planning adjustment unit 16 of the relative contract adjustment device 1 updates the adjustment amount information based on the updated information. The adjustment amount information is set for each frame, that is, for each time zone of 30 minutes. That is, the storage unit 14 stores the adjustment amount information for each time zone of 30 minutes.

As shown in FIG. 9, the adjustment amount information includes information for identifying the contract, an adjustment deadline, an adjustment kicker, a fluctuation absorber, an increase price, a decrease price, a decrease variable amount, and an increase variable amount. It consists of the amount and the amount of fluctuation at the present time. Of the adjustment amount information, the information excluding the adjustment deadline and the fluctuation amount at the present time is the same item as the adjustment condition information, and the same value as the adjustment condition information is stored as the initial value. Further, in the adjustment deadline of the adjustment amount information, the same value as the adjustment deadline of the basic contract information is stored. The adjustment kicker, the fluctuation absorber, the increase price, and the decrease price are not changed by the bilateral contract adjustment device 1, but the decrease variable amount and the increase variable amount are looped as described later. It may be changed by the bilateral contract adjustment device 1 so that the adjustment of the planned value is not performed.

The current fluctuation amount indicates the current cumulative value of the adjustment amount changed from the provisional fixed value by the adjustment process, and the initial value is set to 0. When the planned value of the fluctuation absorber is changed by the adjustment processing of the planned value described later, this adjustment amount is reflected in the current fluctuation amount. That is, the fluctuation amount at the present time is updated every time the planned value is adjusted. The bilateral contract adjusting device 1 adjusts the planned value so that the current fluctuation amount of each bilateral contract does not fall below the downward variable amount and does not exceed the upward variable amount.

Next, the details of the planned value adjustment process by the relative contract adjustment device 1 of the present embodiment will be described. In the adjustment process of the planned value of the present embodiment, the relative contract adjustment device 1 adjusts by using the adjustment condition preset by the fluctuation absorber and the condition requested by the adjustment kicker by the plan adjustment request. Find the variable absorber and adjustment amount that satisfy the conditions. If a request for adjustment of the planned value is received from an arbitrary business operator without deciding the adjustment kicker and the fluctuation absorber, there is a possibility that adjustments in opposite directions may be received at the same time, which complicates the adjustment process. In the present embodiment, by dividing the roles of the adjustment kicker and the fluctuation absorber and performing the adjustment in this way, it is possible to suppress the complexity of the adjustment process and adjust the planned value. ..

FIG. 10 is a flowchart showing an example of a planned value adjustment processing procedure by the relative contract adjustment device 1 of the present embodiment. The process shown in FIG. 10 is performed after the provisional determination of the planned value for the next day described in FIG. As shown in FIG. 10, the plan adjustment unit 16 of the relative contract adjustment device 1 determines whether or not a plan adjustment request has been received from the operator device 2 via the communication unit 11 (step S11). Before the processing shown in FIG. 10 is performed, each business operator has already registered the basic contract information and the adjustment condition information, and the planning adjustment unit 16 of the relative contract adjustment device 1 adjusts based on the adjustment condition information. It is assumed that the amount information is generated and the adjustment amount information is stored in the storage unit 14.

FIG. 11 is a diagram showing a configuration example of a plan adjustment request according to the present embodiment. As shown in FIG. 11, the plan adjustment request indicates the identification information of the business operator indicating the sender business operator, the date and time of the adjustment target, and the amount of change in the planned value that the sender business operator wishes to adjust. The desired adjustment amount and the desired price are included. The business identification information indicating the business operator of the sender is the identification information indicating the business operator of the sender of the plan adjustment request, and the date and time of the adjustment target is the frame subject to the change request of the plan value, that is, 30 minutes. This is information indicating the time zone of. The amount of change desired to be adjusted (hereinafter referred to as the desired amount of adjustment) indicates the amount that the business operator that sends the plan adjustment request wants to change from the current planned value. The desired adjustment amount shall take a negative value when the power is insufficient and a positive value when the power is surplus in the business operator that is the source of the plan adjustment request. For example, in the case of a bilateral contract in which the business operator that sends the plan adjustment request is the power supply source, the desired adjustment amount becomes a negative value when the power to be supplied is insufficient. At this time, in this bilateral contract, the power supplied is reduced, so adjustments are made to reduce the planned value of the supply amount. On the other hand, in the case of a bilateral contract in which the business operator that sends the plan adjustment request is the supply destination to receive the power supply, the desired adjustment amount becomes a negative value when the power supply is insufficient. In the adjustment of the planned value of the bilateral contract, the adjustment to increase the planned value will be made. In this way, even with the same desired adjustment amount, the direction of raising or lowering the planned value in adjusting the planned value differs depending on the direction of power supply under the bilateral contract.

The suggested price is the unit price of the electric energy that changes as a result of changing the planned value from the tentative fixed value, and indicates the unit price desired by the business operator requesting the plan adjustment request. The suggested price is adjusted according to the adjustment amount, which is the amount finally changed by the business operator requesting the change due to the change. When the kicker pays the variable absorber or the variable absorber pays the adjusted kicker. This is the desired unit price for the kicker. Regarding the amount of adjustment, which of the variable absorber and the adjustment kicker will be the payer depends on the direction of power supply specified in the bilateral contract, and which of the power supply source and supply destination is the adjustment kicker. It depends on whether there is an adjustment to lower or raise the planned value. For example, if there is a bilateral contract to supply power from the power generation company A to the retail company a, and the power generation company A is an adjustment kicker, if the adjustment to raise the planned value is made, the power generation company A Receives payment from retailer a. Therefore, considering the interests of the adjusted kicker, the higher the desired unit price, the more desirable. On the other hand, in such a case, the retailer who is a variable absorber is likely to set the lower price in the adjustment condition information low, so if the desired unit price is set high, the adjustment may not be established. There is also sex. Therefore, the adjustment kicker determines the desired unit price according to, for example, the degree of necessity of adjustment.

Return to the explanation of FIG. When it is determined in step S11 that the plan adjustment request has not been received from the operator device 2 (step S11 No), the plan adjustment unit 16 repeats step S11. When it is determined in step S11 that the plan adjustment request has been received from the operator device 2 (step S11 Yes), the plan adjustment unit 16 is relative adjustable by the operator corresponding to the operator device 2 that sent the plan adjustment request. It is determined whether or not there is a contract (step S12). Specifically, the plan adjustment unit 16 refers to the adjustment amount information stored in the storage unit 14, and whether or not there is a bilateral contract in which the business operator that sends the plan adjustment request is the adjustment kicker. To judge.

When the plan adjustment unit 16 determines that there is no bilateral contract that can be adjusted by the operator corresponding to the operator device 2 that has sent the plan adjustment request (step S12 No), the plan adjustment unit 16 ends the process related to the received plan adjustment request. As a result, even if a plan adjustment request is received from a person other than the adjustment kicker, the plan value adjustment process is not executed.

When it is determined that there is a bilateral contract that can be adjusted by the business operator corresponding to the business operator device 2 that has sent the plan adjustment request in step S12 (step S12 Yes), the plan adjustment unit 16 has sent the business operator that has sent the plan adjustment request. The adjustment amount information of the bilateral contract that can be adjusted by the business operator corresponding to the device 2 is extracted (step S13). Specifically, in the plan adjustment unit 16, the business operator that sends the plan adjustment request is the adjustment kicker from the adjustment amount information stored in the storage unit 14, and the adjustment deadline has not passed. , And extract the adjustment amount information of the bilateral contract that satisfies the condition of establishment of the adjustment.

Here, the conditions for establishing the adjustment and the order of the adjustment in the adjustment process of the planned value of the present embodiment will be described for each case. In the following, the business operator of the electric power supply source is also simply referred to as a supply source, and the business operator of the electric power supply destination is also simply referred to as a supply destination. Here, the case No. 1-Case No. The explanation will be divided into four cases up to four. In the following description, the payment direction indicates whether the payment for the electric energy generated by the adjustment is made in the direction from the supply source to the supply destination or from the supply destination to the supply source. The adjustment direction indicates the direction from the adjustment kicker to the change absorber, and when the adjustment kicker is the power supply source, the adjustment direction is the direction from the supply source to the supply destination, and the adjustment kicker In the case of a supply destination, the adjustment direction is from the supply destination to the supply source.

The plan adjustment unit 16 determines the bilateral contract to be adjusted so as to maximize the profit of the business operator of the sender of the plan adjustment request, but in order to maximize the profit of the sender in some cases. , It is different from the bilateral contract that should be considered with priority. For example, Case No. In the case of 1, it is assumed that the changing direction of the planned value is the direction of increasing the planned value, the payment direction is the direction from the supply destination to the supply source, and the adjustment kicker is the supply source. Therefore, the case No. In 1, the adjustment direction is the direction from the supply source to the supply destination, and the adjustment direction and the payment direction do not match. Case No. In the case of 1, when the business operator device 2 corresponding to the adjustment kicker transmits the plan adjustment request, the business operator who sends the plan adjustment request should have the business operator who sent the plan adjustment request purchase higher for the planned value increased by the adjustment. It is advantageous. Therefore, Case No. In 1, the condition for the establishment of the adjustment is that the increase price is equal to or higher than the desired price notified by the plan adjustment request, and the order of proceeding with the adjustment is the order of the increase price. The increased price is set by the variable absorber as described above.

Case No. In the case of 2, it is assumed that the changing direction of the planned value is the direction of increasing the planned value, the payment direction is the direction from the supply destination to the supply source, and the adjustment kicker is the supply destination. Therefore, the case No. In 2, the adjustment direction is the direction from the supply destination to the supply source, and the adjustment direction and the payment direction match. Case No. In 2, when the business operator device 2 corresponding to the adjustment kicker transmits the plan adjustment request, the business operator of the transmission source of the plan adjustment request is more advantageous as the purchase price increased by the adjustment is lower. Therefore, Case No. In 2, the condition for the establishment of the adjustment is that the increase price is equal to or less than the desired price notified by the plan adjustment request, and the order of proceeding with the adjustment is the order of the lowest increase price.

Case No. In the case of 3, it is assumed that the change direction of the planned value is the direction of lowering the planned value, the payment direction is the direction from the supply source to the supply destination, and the adjustment kicker is the supply source. Therefore, the case No. In 3, the adjustment direction is the direction from the supply source to the supply destination, and the adjustment direction and the payment direction match. Case No. In step 3, when the operator device 2 corresponding to the adjustment kicker transmits the plan adjustment request, the operator of the source of the plan adjustment request pays the supplier for the decrease in the planned value due to the adjustment. It will be. Case No. In 3, the lower the amount paid by the adjustment, the more advantageous the business operator who sends the plan adjustment request. Therefore, Case No. In 3, the condition for the establishment of the adjustment is that the reduction price is equal to or less than the desired price notified by the plan adjustment request, and the order of proceeding with the adjustment is the order of the lowest reduction price. As described above, the reduced price is set by the variable absorber.

Case No. In the case of 4, it is assumed that the change direction of the planned value is the direction of lowering the planned value, the payment direction is the direction from the supply source to the supply destination, and the adjustment kicker is the supply destination. Therefore, the case No. In 4, the adjustment direction is the direction from the supply destination to the supply source, and the adjustment direction and the payment direction do not match. Case No. In 4, when the operator device 2 corresponding to the adjustment kicker transmits the plan adjustment request, the operator of the source of the plan adjustment request reduces the planned value of the amount of power supplied by the adjustment. Will be purchased by the supplier. Case No. In 4, it is advantageous for the business operator that sends the plan adjustment request to have a higher purchase price. Therefore, Case No. The condition for the establishment of the adjustment of 4 is that the reduction price is equal to or higher than the desired price notified by the plan adjustment request, and the order of proceeding with the adjustment is in descending order of the reduction price.

The correspondence between the above four cases and the desired adjustment amount is as follows. When the desired adjustment amount is positive, when the adjustment kicker is the supplier, the case No. Corresponding to 1, when the adjustment kicker is the supply destination, the case No. Corresponds to 4. If the desired adjustment amount is negative, the case No. is determined when the adjustment kicker is the supplier. Corresponding to 3, when the adjustment kicker is the supply destination, the case No. Corresponds to 2. Therefore, the bilateral contract extracted in step S13 for one plan adjustment request is the case No. 1 and case No. At least one of 4 or Case No. 2 and case No. At least one of three. Therefore, the bilateral contract extracted in step S13 includes the case No. 1-Case No. Even if the bilateral contracts of a plurality of cases out of 4 are included, the case No. 1 and case No. It is a combination of 4 or case No. 2 and case No. It is a combination of 3. For example, Case No. 1 and case No. Combination of 2, case No. 2 and case No. There is no combination of 4.

Case No. 1 and case No. In No. 4, the items to be referred to are the ascending price and the decreasing price, which are different, but the order of adjustment is in descending order of price. Case No. 2 and case No. In No. 3, the items to be referred to are the ascending price and the decreasing price, which are different, but the order of adjustment is the order of the lowest price. Therefore, in step S13, the plan adjustment unit 16 first extracts from the adjustment amount information that the business operator that sends the plan adjustment request is the adjustment kicker and the adjustment deadline has not passed. The bilateral contract corresponding to the adjusted amount information is the case No. 1 to No. It is determined which of the four is. The planning adjustment unit 16 further extracts the adjustment amount information that satisfies the conditions for establishing the adjustment in each case based on the determination result from the extracted adjustment amount information.

Next, the plan adjustment unit 16 adjusts the plan value by using the extracted adjustment amount information so as to maximize the profit of the business operator who sends the plan adjustment request (step S14). Specifically, the plan adjustment unit 16 sets the adjustment amount corresponding to the bilateral contract to be adjusted so that the profit of the business operator of the sender of the plan adjustment request is maximized within the range satisfying the conditions for establishing the adjustment. And decide. As described above, since the adjustment kicker and the fluctuation absorber are defined for each bilateral contract, the fluctuation absorber to be adjusted is also determined by determining the bilateral contract to be adjusted. The contract.

In step S14, the plan adjustment unit 16 adjusts the plan value based on the order of adjustment according to the above-mentioned case by using the extracted adjustment amount information, thereby performing the business of the transmission source of the plan adjustment request. Adjust the planned value so that the profit of the person is maximized. As described above, even if the desired adjustment amount is the same, whether the requested adjustment is an adjustment that lowers the planned value or an adjustment that raises the planned value differs depending on the direction of power supply for each bilateral contract. become.

Specifically, in step S14, the planning adjustment unit 16 refers to the increase price or the decrease price of each bilateral contract based on whether the desired adjustment amount is positive or negative from the adjustment amount information extracted in step S13. Decide whether to refer to. Then, the planning adjustment unit 16 arranges the bilateral contracts in the order of adjustment determined by the adjustment amount information based on the reference price. As described above, the extracted case No. 1 and case No. 4 is mixed, or case No. 2 and case No. 3 may be mixed. However, although the reference price differs depending on whether the price is an increase price or a decrease price, Case No. 1 and case No. In all of 4, the order of adjustment is in descending order, and although the reference price differs depending on whether the price is an increase price or a decrease price, Case No. 2 and No. In all three, the order of adjustment is in ascending order. Therefore, if the planning adjustment unit 16 determines the price to be referred to, the reference price may be arranged in descending order or in ascending order regardless of the case.

That is, when the desired adjustment amount is a positive value, the planning adjustment unit 16 gives priority to the bilateral contract in which the first price is the second price, which is equal to or higher than the desired adjustment price, in descending order of the first price. Will be decided as the adjustment target. Further, when the desired adjustment amount is a negative value, the planning adjustment unit 16 preferentially determines the adjustment target in order from the bilateral contract in which the first price is less than or equal to the desired adjustment price and the first price is the lowest. It will be. Specifically, when the desired adjustment amount is a positive value, the plan adjustment unit 16 refers to the increase price for the bilateral contract in which the business operator requesting the plan adjustment request is the power supply source, and refers to the request source. Refer to the reduced price for bilateral contracts to which the business is supplied. Further, when the desired adjustment amount is a negative value, the plan adjustment unit 16 refers to the lower price for the bilateral contract in which the requesting company of the plan adjustment request is the power supply source, and the requesting company. Refer to the increased price for bilateral contracts to which is supplied.

Then, in the order determined in the order of adjustment, it is determined whether or not the desired adjustment amount can be covered by the ascending or decreasing variable amount in the bilateral contract corresponding to the extracted adjustment amount information. Whether the desired adjustment amount is referred to or the lower variable amount is referred to in determining whether the desired adjustment amount can be covered depends on whether the desired adjustment amount is positive or negative, and the adjustment kicker is the supplier. It depends on whether it is a supplier or a supplier. Specifically, among the above four cases, the case No. that refers to the increased price. 1, No. In the case of 2, the amount that can be changed is referred to, and the lower price is referred to. 3, No. In the case of 4, the lower variable amount is referred to.

If the desired adjustment amount can be covered by the first bilateral contract in the order of adjustment, the planning adjustment unit 16 determines the bilateral contract as the adjustment target and adjusts the adjustment amount, which is the amount to change the planned value of the bilateral contract. The decision is made, and step S14 ends. If the desired adjustment amount cannot be covered, the planning adjustment unit 16 determines whether the desired adjustment amount can be covered by the first bilateral contract and the second bilateral contract in the order of adjustment. The planning adjustment unit 16 repeats these steps, sequentially increases the number of bilateral contracts to be considered until the desired adjustment amount can be covered, and ends step S14 when the desired adjustment amount can be covered. If the desired adjustment amount cannot be met even after considering all the bilateral contracts corresponding to the extracted adjustment amount information, the adjustment may be made only by the adjustable amount, or it is judged that the adjustment is not possible and the adjustment is made. It does not have to be done.

Returning to the explanation of FIG. 10, the planning adjustment unit 16 reflects the result of the adjustment performed in step S14 in the adjustment amount information of the storage unit 14 (step S15). Specifically, among the adjustment amount information, the adjustment amount, which is the adjustment result of step S14, is reflected in the current fluctuation amount of the bilateral contract determined as the adjustment target. As described above, the fluctuation amount at the present time is the result that the adjustment amount obtained by one adjustment process of the planned value is reflected for each adjustment process. Further, in order to avoid loop-shaped adjustment, the transaction monitoring unit 17 can raise and change the bilateral contract in which the business operator of the source of the plan adjustment request is the fluctuation absorber in the adjustment amount information. Set the amount or lower variable amount to a predetermined value. That is, after the adjustment process is performed, the transaction monitoring unit 17 determines in advance the variable amount corresponding to the bilateral contract in which the business operator requesting the plan adjustment request corresponding to the adjustment process is defined as the fluctuation absorber. Set to the value given. An example of a predetermined value is 0, and the predetermined value will be described below as 0. At this time, whether the transaction monitoring unit 17 sets the corresponding variable amount of the upward variable amount and the downward variable amount to 0 is whether the planned value is adjusted to be increased or decreased. Depends on.

Next, the plan adjustment unit 16 reflects the adjustment result in the plan value information (step S16). Specifically, the plan adjustment unit 16 changes the corresponding plan value of the plan value information stored in the storage unit 14 based on the current fluctuation amount of the bilateral contract determined as the adjustment target. .. The relative contract adjustment device 1 may cause the result output unit 18 to display the changed planned value when the planned value is changed.

Next, the result output unit 18 transmits the adjustment result of the planned value to the corresponding business operator (step S17), and the adjustment process of the planned value is completed. Further, in step S17, when the operator whose planned value is changed by the adjustment process is a operator having the supply and demand management system 3, the OCCTO-related section 19 adjusts the planned value to the corresponding supply and demand management system 3. Notify the change of. Specifically, the OCCTO-related section 19 transmits information necessary for correcting the planned value to the supply / demand management system 3 via the communication section 11. For example, the OCCTO-related section 19 notifies the supply and demand management system 3 of the operator whose planned value has been updated via the communication unit 11 of the amount of change in the planned value changed by adjustment and the corresponding time zone. Alternatively, the planned value changed by the adjustment and the corresponding time zone may be notified. As a result, the supply and demand management system 3 can promptly reflect the adjustment result in the day plan for transmitting the adjustment result to the OCCTO system 4.

Further, in the above example, each time a plan adjustment request is received, the process of step S12 to step S17 shown in FIG. 10, that is, the adjustment process is performed, but the plan received in this fixed period is performed at regular intervals. The processing from step S12 to step S17 may be performed with respect to the adjustment request. When there are a plurality of plan adjustment requests received in a certain period, the processes from step S12 to step S17 are sequentially performed for each of the plurality of plan adjustment requests. That is, the plan adjustment unit 16 determines whether or not one or more plan adjustment requests have been received within a certain period of time, and if it determines that one or more plan adjustment requests have been received, receives the plan adjustment requests within a certain period of time. The adjustment process corresponding to one or more planned adjustment requests may be continuously performed.

Next, the processes of steps S13 and S14 will be described in detail with specific examples. FIG. 12 is a diagram showing an example of a plan value adjustment process of the present embodiment when a plan change request of the first specific example is received. In the first specific example shown in FIG. 12, the operator device 2 of the power generation operator A transmits the plan adjustment request. In this plan adjustment request, the identification information of the business operator is the power generation company A, the date and time of the adjustment target is YYYYMMDD hh: mm, the amount of change desired to be adjusted is -100 kWh, and the desired price is 5 yen / kWh. Suppose it was.

Near the center of FIG. 12, the content of the adjustment amount information corresponding to the time zone frame of YYYYMMDD hh: mm before receiving the plan adjustment request of the first specific example is shown. In this adjustment amount information, for convenience of explanation, No (contract No.), which is a number for identifying a bilateral contract, is shown at the left end. Of the adjustment amount information shown in FIG. 12, the bilateral contract in which the power generation company A is a party is the contract No. 1 to No. It is four of four. Contract No. Reference numeral 1 denotes a bilateral contract for supplying electric power from the power generation company A to the retail company b, and the adjustment kicker is the power generation company A. Contract No. Reference numeral 2 denotes a bilateral contract for supplying electric power from the power generation company A to the retail company c, and the adjustment kicker is the retail company c. Contract No. Reference numeral 3 denotes a bilateral contract for supplying electric power from the power generation company A to the retail company d, and the adjustment kicker is the power generation company A. Contract No. Reference numeral 4 denotes a bilateral contract for supplying electric power from the retailer a to the power generation company A, and the adjustment kicker is the retailer a.

Upon receiving the plan adjustment request of the first specific example, the relative contract adjustment device 1 determines Yes in step S11 shown in FIG. 10, and performs the process of step S12. In step S12, the plan adjustment unit 16 of the relative contract adjustment device 1 determines in the adjustment amount information whether or not there is a relative contract in which the power generation company A, which is the source of the plan adjustment request, is the adjustment kicker. to decide. As shown in FIG. 12, since there is a bilateral contract in which the power generation company A is the adjustment kicker in the adjustment amount information, the planning adjustment unit 16 proceeds to step S13. Here, it is assumed that the time when the bilateral contract adjustment device 1 receives the plan adjustment request is before 60 minutes before YYYYMMDD hh: mm, that is, before the adjustment deadline.

In step S13, in the plan adjustment unit 16 of the relative contract adjustment device 1, the power generation company A is the adjustment kicker, and the contract No. 1 and contract No. 3 is extracted. In FIG. 12, the adjustment amount information extracted in step S13 is shown as information 301. When the desired adjustment amount is a negative value, the above-mentioned case No. 2, No. In the first specific example, the power generation company A is the supplier of all the bilateral contracts in which the power generation company A is the adjustment kicker. Therefore, both of these two cases No. Since it corresponds to 3, the planning adjustment unit 16 compares the reduced price with the desired price in step S13. As described above, the initial values of the fluctuation amount at the present time are all set to 0, but in FIG. 12, the planned values have already been adjusted for the time zone of YYYYMMDD hh: mm. According to the contract No. It is assumed that the current fluctuation amount of 1 is set to -100 kWh.

In the process of step S14, the plan adjustment unit 16 of the relative contract adjustment device 1 sets the contract No. 1 and contract No. With regard to 3, adjustments will be made in ascending order of lower price. As shown in FIG. 12, the contract No. The reduced price of 1 is 2 yen / kWh, and the contract No. Since the reduced price of 3 is 3 yen / kWh, the contract No. 1 is cheaper than the lower price. Therefore, the planning and coordinating unit 16 has the contract No. Perform adjustments from 1. The planning and coordinating unit 16 has a contract No. The amount of variable reduction of 1 is -130 kWh, and the contract No. Since the current fluctuation amount of 1 is -100 kWh, the current fluctuation amount, which is the amount already changed by adjustment, is subtracted from the downward variable amount, and the contract No. Find the adjustable amount of 1. Contract No. The adjustable amount of 1 can be calculated by the following formula (1), and is -30 kWh.
-130- (-100) = -30 ... (1)

Since the desired adjustment amount is -100kWh, the desired adjustment amount cannot be covered by the adjustment of -30kWh. Therefore, the planning and coordination unit 16 has the contract No. 1 and contract No. Of the three, the contract No. with the second lowest price reduction. With reference to the adjustment amount information of No. 3, the contract No. As in 1, the adjustable amount is calculated. Contract No. Since the amount of fluctuation of 3 is -80 kWh and the amount of fluctuation at the present time is 0 kWh, the contract No. The adjustable amount of 3 is -80 kWh.

Contract No. 1 is the contract No. Since the lower price is lower than 3, the planning and coordination department 16 has the contract No. Prioritize the adjustment according to 1, and contract No. The adjustment amount of 1 is -30kWh, and the contract No. An adjustment result is obtained in which the adjustment amount of 3 is -70 kWh. Further, the transaction monitoring unit 17 has a contract No. 1 in which the power generation company A is a fluctuation absorber in order to avoid loop-shaped adjustment. 2 and contract No. Extract the adjustment information of 4. In FIG. 12, the adjustment amount information extracted by the transaction monitoring unit 17 is shown as information 302. The transaction monitoring unit 17 sets the amount of downward fluctuation of the extracted adjustment amount information to 0.

FIG. 13 is a diagram showing an example of a plan value adjustment process of the present embodiment when a plan change request of the second specific example is received. In the second specific example shown in FIG. 13, the operator device 2 of the power generation operator A has the identification information of the operator as the power generation operator A and the date and time of the adjustment target are set as in the first specific example. YYYYMMDD hh: mm, the amount of change desired to be adjusted is -100kWh, and the desired price is 5 yen / kWh.

Near the center of FIG. 13, the content of the adjustment amount information corresponding to the time zone frame of YYYYMMDD hh: mm before receiving the plan adjustment request of the second specific example is shown. This adjustment amount information includes the first specific example and the contract No. 3 and contract No. Although the contents of No. 6 are different, the adjustment amount information of the first specific example is the same except for these. Contract No. The adjustment amount information of No. 3 is the same as that of the first specific example except that the reduced price is different from that of the first specific example. Contract No. Reference numeral 6 denotes a bilateral contract for supplying electric power from the power generation company B to the power generation company A, and the adjustment kicker is the power generation company A. Of the adjustment amount information shown in FIG. 13, the bilateral contract in which the power generation company A is a party is the contract No. 1 to No. 4, No. There are five of six.

Similar to the first specific example, when the relative contract adjustment device 1 receives the plan adjustment request, it is determined to be Yes in step S11 shown in FIG. 10, and the process of step S12 is performed. Similarly, the process proceeds to step S13. Here, as in the first specific example, it is assumed that the time when the bilateral contract adjustment device 1 receives the plan adjustment request is before 60 minutes before YYYYMMDD hh: mm, that is, before the adjustment deadline.

In the second specific example, in step S13, in the plan adjustment unit 16 of the relative contract adjustment device 1, the power generation company A is the adjustment kicker, and the contract No. 1 and contract No. 3 and the contract No. whose raised price is less than the desired price. 6 and are extracted. In FIG. 13, similarly to FIG. 12, the adjustment amount information extracted in step S13 is shown as information 301. In the second specific example, the case No. Contract No. corresponding to 3 1 and contract No. 3 and case No. Contract No. 2 corresponding to 6 and are mixed. The plan adjustment unit 16 has a case No. For the contract corresponding to No. 3, the reduced price is set, and Case No. For contracts corresponding to 2, refer to each of the raised prices and make adjustments in ascending order of the referenced prices.

As shown in FIG. 13, the contract No. The reduced price of 1 is 2 yen / kWh, and the contract No. The reduced price of 3 is 4 yen / kWh, and the contract No. The increased price of 6 is 3 yen / kWh. Therefore, when these are arranged in ascending order, the contract No. Lower price of 1, No. Increased price of 6, contract No. The order is the lower price of 3. Therefore, the planning and coordination unit 16 has the contract No. Perform adjustments from 1. Contract No. The adjustable amount of 1 is −30 kWh as in the first specific example. Since the desired adjustment amount is -100 kWh, the desired adjustment amount cannot be covered by the adjustment of -30 kWh. Therefore, the planning and coordinating unit 16 has the next lowest price contract No. The adjustable amount is obtained by referring to the adjustment amount information of 6. The contract No. No. 6 is the case No. In order to correspond to 2, adjustments are made in the direction of increasing the planned value. Specifically, the planning and coordinating unit 16 has a contract No. The variable amount of increase in 6 is (+) 120 kWh, and the variable amount at the present time is 0 kWh. The adjustable amount of 6 is 120 kWh.

Contract No. The reduced price of 1 is the contract No. Since it is cheaper than the increased price of 6, the planning and coordinating unit 16 has the contract No. Prioritize the adjustment according to 1, and contract No. The adjustment amount of 1 is -30kWh, and the contract No. An adjustment result is obtained in which the adjustment amount of 3 is (+) 70 kWh. Further, in the transaction monitoring unit 17, in order to avoid loop-shaped adjustment, the contract No. 2 and contract No. Extract the adjustment information of 4. In FIG. 13, as in FIG. 12, the adjustment amount information extracted by the transaction monitoring unit 17 is shown as information 302. The transaction monitoring unit 17 sets the amount of downward fluctuation of the extracted adjustment amount information to 0.

Next, the change operation of the variable amount performed by the transaction monitoring unit 17 in order to avoid the loop-shaped adjustment will be described. FIG. 14 is a diagram for explaining a variable amount changing operation performed by the transaction monitoring unit 17 of the present embodiment. In the example shown in FIG. 14, there are three bilateral contracts indicated by the arrows in FIG. 14 between the power generation company C, the retail company a, and the retail company f. Specifically, the three bilateral contracts are a contract 401 in which the retailer a supplies power to the power generation company C, a contract 402 in which the power generation company C supplies power to the retailer f, and a retailer. It is a contract 403 in which f supplies electric power to the retailer a. In contract 401, the adjustment kicker is retailer a, in contract 402 the adjustment kicker is power generation company C, and in contract 403 the adjustment kicker is retailer f. Further, it is assumed that the planned value in the plan for the next day of the contract 402 is 200 kwh, the planned value in the plan for the next day of the contract 403 is 100 kwh, and the planned value in the plan for the next day of the contract 401 is 100 kwh. In the figure, the unit of the planned value is omitted.

As shown in FIG. 14, after the planned value in the plan for the next day is tentatively determined, it is assumed that the generator of the power generation company C fails as (1) and the power generation company C is in a state of insufficient power. As a result, the power generation company C uses the company device 2 to transmit the plan adjustment request with the desired adjustment amount of −100 kWh to the relative contract adjustment device 1 as (2). The relative contract adjustment device 1 adjusts the planned value based on the planned adjustment request, and as a result, the contract 402 is selected as the adjustment target and the planned value of the contract 402 is changed to 100 kWh.

FIG. 15 is a diagram showing a state after the planned values shown in FIG. 14 have been adjusted. As shown in FIG. 15, by adjusting the planned value described in FIG. 14, the planned value of the contract 402 has been changed to 100 kWh, which causes the retailer f to run out of electric power. , (3), the business operator device 2 is used to transmit a plan adjustment request with the desired adjustment amount to −100 kWh to the relative contract adjustment device 1. The relative contract adjustment device 1 adjusts the planned value based on the planned adjustment request, and as a result, the contract 403 is selected as the adjustment target and the planned value of the contract 403 is changed to 0 kWh. As a result, the retailer a becomes in a state of running out of electric power, and as (4), the retailer a sends a plan adjustment request with a desired adjustment amount of −100 kWh to the relative contract adjustment device 1 using the operator device 2.

Here, when the relative contract adjustment device 1 receives the plan adjustment request of (4) and reduces the planned value by 100 kWh with the contract 401 as the target of the adjustment of the planned value, it is supplied to the power generation company C. The power generation will be reduced, and the power generation company C will send the plan adjustment request again using the company device 2. That is, in this example, if the planned value of the contract 401 is reduced by 100 kWh, the loop-shaped adjustment will be performed. In order to avoid such a loop-shaped adjustment, in the present embodiment, the transaction monitoring unit 17 changes the variable amount. That is, the transaction monitoring unit 17 corresponds to the direction in which the planned value is adjusted among the ascending and descending variable amounts of the bilateral contract in which the business operator that sends the plan adjustment request is the fluctuation absorber. Change the variable amount to 0 kWh.

FIG. 16 is a diagram showing an example of changing the variable amount by the transaction monitoring unit 17 of the present embodiment. FIG. 16 is a diagram showing adjustment amount information corresponding to the example shown in FIG. The three contracts shown in FIG. 16 correspond to

contracts

401, 402, and 403 in order from the top. FIG. 16 shows a state after the relative contract adjusting device 1 changes the planned value of the contract 401 based on the planned adjustment request of FIG. 14 (2). Therefore, the current fluctuation amount of the contract 402 shown in FIG. 14, which is the second contract from the top of FIG. 16, is −100 kWh. As shown in column 303, the downward variable amount of contract 401 shown in FIG. 14, which is the first contract from the top of FIG. 16, is -100 kWh before the adjustment of the planned value of contract 402, but transaction monitoring. It is changed to 0 kWh by the unit 17 after adjusting the planned value of the contract 402. As a result, even if the bilateral contract adjustment device 1 subsequently receives a plan adjustment request with the desired adjustment amount as a negative value from the retailer a, the plan value of the contract 401 is not changed, so that the loop shape is formed. No adjustments occur.

Also, if the plan adjustment request is sent indefinitely and frequently, the plan value will be adjusted frequently, which is not preferable for other businesses. Further, if the plan adjustment request is frequently transmitted, the load of the relative contract adjustment device 1 also increases. Therefore, a fee may be provided for sending the plan adjustment request. Further, an upper limit may be set on the number of times the plan adjustment request is transmitted from one business operator for the same 30-minute time zone. Further, even if there is an excessive request for the desired adjustment amount, the influence on other businesses will be large. Therefore, a pay-as-you-go rate for the desired adjustment amount may be provided.

As described above, in the present embodiment, the adjustment kicker and the fluctuation absorber who can request the adjustment of the planned value are defined for each bilateral contract, and the fluctuation absorber changes the planned value. The adjustment conditions including the variable amount, which is the maximum allowable amount, and the allowable unit price when changing the planned value are defined in advance. Then, when the bilateral contract adjustment device 1 receives the plan adjustment request requesting the change of the plan value from the operator device 2 corresponding to the adjustment kicker, the adjustment amount and the desired unit price included in the plan adjustment request are desired to be adjusted. Based on the desired price and the adjustment conditions, the relative contract to be adjusted is determined, and the adjustment amount for each relative contract to be adjusted is calculated. As a result, the relative contract adjusting device 1 of the present embodiment can adjust the planned value of the supply and demand amount of the business operator who has concluded the bilateral contract while suppressing the labor.

The operation of the plan adjustment unit 16 of the present embodiment is the same as that of the plan adjustment unit 16 of the first embodiment. However, in the present embodiment, when the adjustment request generation unit 25 generates the plan adjustment request, the adjustment request generation unit 25 transmits the plan adjustment request to the plan adjustment unit 16. When the plan adjustment unit 16 receives the plan adjustment request from the adjustment request generation unit 25, the plan adjustment unit 16 performs the same operation as when the plan adjustment request is received in step S11 shown in FIG. Alternatively, the plan adjustment unit 16 may transmit the received plan adjustment request to the other operator device 1a via the storage unit 14, the information propagation unit 27, and the communication unit 11. Further, when the plan adjustment unit 16 receives the plan adjustment request from the other operator device 1a via the communication unit 11, the information propagation unit 27, and the storage unit 14, it is the same as the plan adjustment unit 16 of the first embodiment. Do the action. Further, as in the first embodiment, the plan value adjustment process may be performed every time the plan adjustment request is received, or the process corresponding to the plan adjustment request received in the fixed period is performed at regular intervals. May be good.

The operator device 1a of the present embodiment is realized by a computer system like the relative contract adjustment device 1 and the operator device 2 of the first embodiment. The operator device 1a is realized by the computer system shown in FIG. 3, for example, similarly to the bilateral contract adjustment device 1. In the operator device 1a of the present embodiment, the computer system functions as the operator device 1a by executing a program in which the processing in the operator device 1a is described on the computer system. The operation of the computer system until the program becomes executable is the same as that of the relative contract adjustment device 1 of the first embodiment.

The operation of the present embodiment other than that described above is the same as that of the first embodiment. In the present embodiment, the planned value adjustment process is performed by the blockchain configured by the operator device 1a of each operator. As a result, the same effect as that of the first embodiment can be obtained. Further, in the first embodiment, the relative contract adjustment device 1 adjusts the planned value by the central management method. Therefore, when the relative contract adjustment device 1 is managed by a certain business operator, this business operator is relative. Even if the content of the adjustment process of the planned value in the contract adjustment device 1 is changed, other businesses cannot understand it. Therefore, there is a possibility that fairness cannot be maintained, but in the present embodiment, since all the operator devices 1a can perform the same processing, fairness can be ensured.

1 and 2 described above, the variable absorber determines the adjustment conditions for each bilateral contract. Not limited to this, the adjustment conditions may be determined for each business operator. That is, each business operator may set the increase price, the decrease price, the increase changeable amount, and the decrease variable amount when becoming a fluctuation absorber as common values regardless of the bilateral contract. In this case, the adjustment condition information shown in FIG. 8 is composed of information for each business operator, not for each bilateral contract. Therefore, the adjustment condition information is determined for each business operator, and the variable amount indicating the amount of change of the planned value from the tentative fixed value that the business operator can accept and the planned value are changed from the tentative fixed value. This includes the first price, which is the unit price of the electric energy that is generated and changed and indicates the unit price that the business operator can accept.

For example, suppose that the power generation company A concludes a bilateral contract with the retailer a and a bilateral contract with the retailer b. Assuming that the power generation company A is set as the fluctuation absorber in these two bilateral contracts, the planning and coordinating unit 16 makes common adjustments corresponding to the power generation company A when determining the bilateral contract to be adjusted. With reference to the conditions, the same processing as in the first and second embodiments is performed. That is, the plan adjustment unit 16 adjusts based on the first price and the variable amount in the adjustment condition information of the fluctuation absorber, which is the second business operator, and the second price and the desired adjustment amount in the plan adjustment request. Perform processing. Specifically, for example, when the plan adjustment unit 16 generates the adjustment amount information shown in FIG. 9, it reads out the adjustment condition information corresponding to the business operator of the fluctuation absorber for each bilateral contract, and adjusts the adjustment amount information. Store in. As a result, the subsequent operations can be the same as those in the first and second embodiments. In this way, if the adjustment conditions are set for each business operator, each business operator does not need to set the adjustment conditions for each bilateral contract, and the man-hours for registration and management in each business operator can be suppressed.

The configuration shown in the above-described embodiment shows an example of the content of the present invention, can be combined with another known technique, and is one of the configurations without departing from the gist of the present invention. It is also possible to omit or change the part.
