Description

Technical Field

[0001] The present invention relates to a regional supply and demand management device, a distribution congestion management device, and a regional supply and demand management method, and more particularly to a regional supply and demand management device, a distribution congestion management device, and a regional supply and demand management method for alleviating system congestion in a distribution system.

Background Art

[0002] In recent years, the introduction of distributed energy resources (hereinafter referred to as DERs (Distributed Energy Resources)) into the power system has been expanding. In a distribution system with a high introduction ratio of DERs, system congestion occurs due to surplus power from renewable energy (hereinafter referred to as renewable energy) power sources or heavy loads caused by heat pumps and electric vehicles. Although system congestion can be addressed by expanding system facilities, the costs and time required for facility introduction become issues. Therefore, means for alleviating system congestion by utilizing the adjustment power (hereinafter referred to as in-area adjustment power) that can be supplied by DERs connected to the power system (hereinafter referred to as the in-area power system) in the area where system congestion has occurred are being studied.

[0003] As a power infrastructure system, there is a need for measures to reduce the total amount of adjustment power required for power supply and not increase the electricity bills of consumers. The object of the present invention is to provide means for reducing the total amount of in-area adjustment power necessary for a distribution utility (hereinafter referred to as DSO (Distributed System Operator)) to alleviate system congestion caused by renewable energy surplus or the like.

[0004] As background technology for this field, there is Japanese Patent Publication No. 2024-005510 (Patent Document 1). The publication states that the challenge is to "realize market trading of electricity in a way that suppresses investment in strengthening distribution systems within the distribution domain," and as a means to solve this, it describes the system as comprising: a system model creation unit that creates a distribution system model based on distribution system information including wiring information of the target distribution system and specification information of the equipment constituting the distribution system; a market trading unit that acquires bidding information, including the desired operating schedule of the distributed resources, from information management devices of multiple market participants that manage the distributed resources connected to the distribution system; a simulation unit that applies the acquired bidding information to the distribution system model to perform power flow and voltage calculations for the distribution system by time of day and location, and derives an optimal operating schedule that satisfies the constraints of the equipment constituting the distribution system; and a notification unit that notifies the information management devices of the market participants of the optimal operating schedule. The embodiment states that "the optimal operating schedule is an operating schedule that satisfies the constraints of the distribution equipment, obtains a supply and demand amount that satisfies the forecast of electricity supply and demand for the next day, and is also an operating schedule that results in the lowest electricity price."

[0005] [Patent Document 1] Japanese Patent Publication No. 2024-005510 [Overview of the project] [Problems that the invention aims to solve]

[0006] The technology described in Patent Document 1 is a method for deriving an operating schedule for a DER that satisfies grid constraints such as grid congestion, but it does not take into account other operational purposes of DER operation. As a result, when each business operator that owns or operates a DER as an on-site adjustment capacity, such as aggregators, power generators, retail electricity companies, and DSOs (hereinafter simply referred to as "business operators"), formulates their respective power generation plans, there are problems such as inefficiencies in the use of adjustment capacity due to overlaps and inverse supply and demand among the multiple power generation plans.

[0007] This invention was made to solve the above problems. Specifically, one of the objectives of this invention is to provide a regional supply and demand management device, a distribution congestion management device, and a regional supply and demand management method that can reduce the possibility of inefficient utilization of adjustment power. [Means for solving the problem]

[0008] To solve the aforementioned problems, the present invention provides a regional supply and demand management device that includes an information processing device having a processor and a memory device, and is applied to regional supply and demand management in which multiple operators divide local adjustment power into shared adjustment power operated among the operators and other adjustment power other than the shared adjustment power, and use the local adjustment power to alleviate grid congestion, wherein the processor is configured to define multiple operational objectives of the shared adjustment power, including at least grid congestion alleviation as specific operational objectives, and to plan the power generation plans of the interconnection DER connected to the local grid, which is the power grid of the area where the grid congestion occurs, and the shared adjustment power, respectively, so as to satisfy the specific operational objectives.

[0009] The power distribution congestion management device of the present invention includes an information processing device having a processor and a memory device, and is a power distribution congestion management device applied to regional supply and demand management in which multiple operators divide local adjustment capacity into shared adjustment capacity operated among the operators and other adjustment capacity other than the shared adjustment capacity, and uses the local adjustment capacity to alleviate grid congestion, wherein the processor sets a number of operational purposes, including at least grid congestion alleviation of the shared adjustment capacity, as specific operational purposes, plans the power generation plans so that the power generation plans of the interconnection DER connected to the local grid, which is the power grid of the area where the grid congestion occurs, and the shared adjustment capacity satisfy the specific operational purposes, calculates congestion information based on the supply and demand forecast of the local grid and the grid control plan of the grid control equipment, creates bidding information to the market, including the power and adjustment capacity market, in accordance with the power generation plan, and executes market transactions, The system is configured to control the DER in accordance with the power generation plan, monitor whether or not grid congestion is occurring in the distribution system, and, if necessary, implement countermeasures by remotely controlling the grid control equipment and the interconnection DER.

[0010] The present invention relates to a regional supply and demand management method that uses an information processing device having a processor and a memory device to operate local adjustment forces by dividing their capacity into shared adjustment forces operated among the businesses and other adjustment forces other than the shared adjustment forces, and to a regional supply and demand management method that uses the local adjustment forces to alleviate grid congestion. The method is applied to regional supply and demand management that uses local adjustment forces to alleviate grid congestion. The processor defines several operational objectives of the shared adjustment forces, including at least grid congestion alleviation, as specific operational objectives, and plans the power generation plans of the interconnection DER connected to the local grid, which is the power grid of the area where grid congestion occurs, and the shared adjustment forces, so as to satisfy the specific operational objectives. [Effects of the Invention]

[0011] According to the present invention, when a DSO plans congestion mitigation, it is possible to avoid conflicting use of adjustment power among multiple operators by using a shared adjustment power generation plan, while also satisfying the specific operational objectives of each operator. This makes the use of adjustment power more efficient. The effects described herein are not necessarily limited and may include any of the effects described in this disclosure.

[0013] Hereinafter, an embodiment of a regional supply-demand management method to which the present invention is applied will be described with reference to the drawings. In all the drawings of the embodiment, the same or corresponding parts may be denoted by the same reference numerals.

[0014] <<Embodiment>> FIG. 1 is an overall example of a system to which the regional supply-demand coordination platform is linked. FIG. 2 is a functional configuration example of the regional supply-demand coordination platform capable of realizing the regional supply-demand management method.

[0015] As shown in FIG. 1, the system includes a regional supply-demand coordination platform 901, a distribution management system (hereinafter referred to as DMS) 902 operated by the DSO, a plurality of resource aggregation systems (hereinafter referred to as RA systems) 903 operated by a plurality of resource aggregators, and a TSO system operated by the TSO (Transmission System Operator). These are configured to be communicable via a network not shown.

[0016] As shown in FIG. 2, the regional supply-demand coordination platform 901 includes at least a shared regulation power management unit 101, a system congestion information acquisition unit 102, a DER supply-demand information acquisition unit 103, a linked DER / shared regulation power operation planning unit 104, a plan notification unit 105, an external interface unit 106, and a database unit 107. The regional supply-demand coordination platform 901 may be referred to as a "regional supply-demand management device".

[0017] The shared regulation power management unit 101 registers and manages the shared regulation power operated (hereinafter referred to as coordinated operation) among multiple operators. The system congestion information acquisition unit 102 acquires system congestion information from the distribution management system 902. The DER supply-demand information acquisition unit 103 acquires DER supply-demand information such as the power generation amount and power demand of the DER from at least one or more resource aggregation systems 903 together with the location information or system information of the DER.

[0018] The interconnected DER / shared adjustment capacity operation planning unit 104 identifies multiple operational objectives for the shared adjustment capacity and plans the power generation plans of the DERs connected to the local grid and the shared adjustment capacity to satisfy these specific operational objectives. The plan notification unit 105 notifies the DMS 902 and the RA system 903 of the plan (hereinafter referred to as the coordinated operation plan). The external interface unit 106 communicates with the DMS 902, the RA system 903, and the TSO system 904 operated by the transmission operator to exchange necessary information. The database unit 107 records data such as the registration information of the shared adjustment capacity, the grid congestion information, the DER supply and demand information, and the coordinated operation plan.

[0019] The processing of each part will be explained using Figure 3, which shows an example of the overall sequence of regional supply and demand management. Businesses using the regional supply and demand coordination platform 901 operate by dividing the local adjustment capacity into the shared adjustment capacity and other adjustment capacity. The shared adjustment capacity is not so much a partial exclusive right to use the DER, but rather a portion of the DER's capacity to which electricity can be preferentially exchanged. The response requirements are less stringent than those of secondary and tertiary adjustment capacity, and by planning in advance, it is possible to trade and settle electricity quantities in units of capacity and time.

[0020] In processing 202, the shared adjustment capacity management unit 101 acquires the shared adjustment capacity from the DMS 902 and the RA system 903 via the external interface unit 106, along with location information, electricity rate plans, transformer information, aggregator information, resource information, system operator information, system information, etc., and registers it in the database unit 107.

[0021] In processing 203, the grid congestion information acquisition unit 102 acquires the grid congestion information from the DMS 902 via the external interface unit 106 and stores it in the database unit 107. This grid congestion information includes at least the grid congestion management nodes based on supply and demand forecasts and the required congestion mitigation amount. In addition, the DER supply and demand information is acquired from the RA system 903 via the external interface unit 106 and stored in the database unit 107. This DER supply and demand information includes at least the power generation forecast value and demand forecast value of the interconnected DER, and the demand response (hereinafter, DR) schedule information. The DER supply and demand information acquisition unit 103 acquires the DER location information or grid information together with the DER supply and demand information only the first time, and from the second time onward, it may use the location information or grid information stored in the database unit 107.

[0022] The interconnected DER / shared adjustment capacity operation planning unit 104 creates the aforementioned coordinated operation plan in processing 205. Examples of such specific operation objectives include mitigating grid congestion for DSOs, avoiding imbalances for aggregators and power generators, and demand response (DR) for aggregators and retail electricity providers. The interconnected DER / shared adjustment capacity operation planning unit 104 creates, for example, a congestion mitigation coordinated plan, an imbalance avoidance coordinated plan, and a DR coordinated plan as the aforementioned coordinated operation plans.

[0023] In processing 206, the plan notification unit 105 notifies the DMS 902 and the RA system 903 of the various cooperative operation plans via the external interface unit 106. The operator creates a power generation plan that takes the cooperative operation plan into account, conducts a market bid, and controls the DER at the actual supply and demand time according to the contract results.

[0024] In an example where the specific operational purpose of the shared adjustment capacity is grid congestion mitigation and imbalance avoidance, Figure 4 shows an example of a congestion mitigation / imbalance avoidance coordinated planning flow. In step S301, the interconnected DER / shared adjustment capacity operation planning unit 104 converts the input data 301, such as the grid congestion information and the DER supply and demand information, into a data format that enables coordinated planning for congestion mitigation and imbalance avoidance, and saves it as setting data 302 in the database unit 107.

[0025] In step S302, the interconnected DER / shared adjustment capacity operation planning unit 104 uses the setting data 302 to formulate a coordination plan for the specific operation purpose and creates a congestion mitigation coordination plan 303 and an imbalance avoidance coordination plan 304. The shared adjustment capacity targeted by the congestion mitigation coordination plan 303 is the shared adjustment capacity that is determined to act on the reverse power flow of the congestion management node included in the grid congestion information, based on the grid information registered in the regional supply and demand coordination platform 901. The interconnected DERs targeted by the imbalance avoidance coordination plan 304 are DERs from which the DER supply and demand information has been acquired that are determined to act on the reverse power flow of the congestion management node based on the location information or grid information.

[0026] Figure 5 shows an example of a coordinated plan format for congestion mitigation and imbalance avoidance. When grid congestion due to a surplus of renewable energy is a concern, the congestion mitigation coordinated plan 401 is the congestion mitigation demand 404 for each time slot of the shared adjustment capacity 403 that is the target of the congestion mitigation coordinated plan 303. The plan is designed so that the total value 408 of this congestion mitigation demand 404 satisfies the required amount of congestion mitigation. Note that in Figure 5, the specific demand amount (MWh) within the box of congestion mitigation demand 404 is omitted. In reality, the congestion mitigation coordinated plan 401 is a document that includes the demand amount (MWh) for each time slot according to the plan for the shared adjustment capacity 403 that is the target of the congestion mitigation coordinated plan 303.

[0027] The imbalance avoidance coordination plan 405 is the amount of imbalance compensation available for each time slot of the interconnected DER 406 that is the target of the imbalance avoidance coordination plan 304. The imbalance compensation available for each interconnected DER is planned so that the amount of imbalance compensation available for each interconnected DER is less than or equal to the predicted power generation value, and the total value of the imbalance compensation available for each DER 407 409 is less than or equal to the total value of the congestion relief demand 404. Note that in Figure 5, the amount of power generation (MWh) representing the imbalance compensation available for each DER is omitted. In reality, the imbalance avoidance coordination plan 405 is a document in which the amount of power generation (MWh) according to the plan is indicated for the time slots corresponding to the interconnected DERs that are the target of the imbalance avoidance coordination plan 304.

[0028] Normally, when an imbalance occurs in a grid-connected DER, if an aggregator or power generator increases its power generation, both adjustment capacity necessary for increasing power generation and adjustment capacity necessary for alleviating congestion are required. For example, if the congestion relief demand is planned at aMWh, and an imbalance of bMWh occurs at the time of actual supply and demand, the aggregator will need a total of aMWh (demand) + bMWh (generation) of local adjustment capacity to compensate for the imbalance by bMWh.

[0029] In this invention, by reducing the congestion relief demand of the shared adjustment force within the range of the amount of imbalance that can be compensated, it is possible to address the insufficient imbalance using only the adjustment force necessary for congestion relief. This makes it possible to reduce the total amount of adjustment force required for congestion relief and imbalance avoidance.

[0030] In other words, the congestion relief demand planned at aMWh in the above example can be changed to a-bMWh(demand) at the time of actual supply and demand, and the local adjustment capacity required to compensate for imbalances of aMWh or less (in this example, compensation for a deficit imbalance of bMWh (b≦a)) will be only aMWh(demand) (=(a-bMWh(demand)+bMWh(generation))) required for congestion relief. That is, by reducing the congestion relief demand, the amount that can compensate for imbalances (generation) can be reduced, and thus the total amount of local adjustment capacity can be reduced. Note that if b is greater than a, it will hinder congestion relief, so in order to satisfy the specific operational purpose (the purpose of both grid congestion relief and imbalance avoidance), it is necessary to plan so that the total value 409 of the amount that can compensate for imbalances 407 is less than or equal to the total value of the congestion relief demand 404. Note that the amount bMWh of imbalance compensation using the shared adjustment capacity (aMWh(demand) only) will be either traded between operators before gate closure or settled afterward.

[0031] In an example where the specific operational purpose of the shared adjustment capacity is grid congestion mitigation and DR, Figure 6 shows an example of a congestion mitigation / DR coordinated planning flow. In step S501, the interconnected DER / shared adjustment capacity operation planning unit 104 converts input data 501, such as the grid congestion information and the DER supply and demand information, into a data format that enables a coordinated planning of congestion mitigation and DR, and saves it as setting data 502 in the database unit 107. In step S502, the interconnected DER / shared adjustment capacity operation planning unit 104 uses the setting data 502 to formulate a coordinated plan for the specific operational purpose and creates a congestion mitigation coordinated plan 503 and a DR coordinated plan 504.

[0032] The shared adjustment capacity subject to the congestion mitigation coordination plan 503 is the shared adjustment capacity that is determined to act on the forward power flow of the congestion management node included in the system congestion information, based on the system information registered in the regional supply and demand coordination platform 901. Furthermore, the interconnected DER subject to the DR coordination plan 504 is a DER that is capable of DR, among the DERs that have acquired the DER supply and demand information, and which is determined to act on the forward power flow of the congestion management node based on the location information or system information.

[0033] Figure 7 shows an example of a congestion mitigation and demand response (DR) coordination plan format. When grid congestion due to heavy load is a concern, the congestion mitigation coordination plan 601 is the amount of congestion mitigation power generation 604 for each time slot of the shared adjustment capacity 603 that is the target of the congestion mitigation coordination plan 503. Note that in Figure 7, the specific amount of power generation (MWh) showing congestion mitigation power generation is omitted. In reality, the congestion mitigation coordination plan 601 is a document in which the amount of power generation (MWh) according to the plan is entered for the time slots corresponding to the shared adjustment capacity 403 that is the target of the congestion mitigation coordination plan 605.

[0034] Furthermore, the DR coordination plan 605 is the DR command information 607 for each time frame of the interconnected DER 606 that is the target of the DR coordination plan 504. The DR command information 607 is, for example, information indicating commands to the equipment that controls the DER in order to perform DR. In Figure 7, specific information indicating the DR command information is omitted. In reality, the DR coordination plan 605 is a document in which DE command information according to the plan is entered for the time frames corresponding to the interconnected DER 606 that is the target of the DR coordination plan 504.

[0035] The plan is to ensure that the sum of the demand forecast value for each interconnected DER, the DR scheduled information, the DR activation amount 609 based on the DR command information, and the congestion mitigation power generation amount 604, totaling 608, satisfies the required congestion mitigation amount.

[0036] Normally, when an aggregator or retail electricity provider activates demand response (DR) in a grid-connected DER (Demand Response), the necessary adjustment capacity to alleviate congestion is used to further reduce demand through DR.

[0037] For example, if the planned amount of power generation for congestion mitigation is cMWh, and a demand response (DR) of dMWh is activated at the actual supply and demand time, a total of c+dMWh(cMWh(power generation)+dMWh(DR)) of local adjustment power will be used. In this invention, by using the planned DR information and incorporating the DR into the congestion mitigation coordination plan in advance, the amount of adjustment power required for grid congestion mitigation can be reduced. In other words, the amount of power generation for congestion mitigation that was planned as cMWh in the above specific example can be changed to c-dMWh(power generation), and the total local adjustment power used for grid congestion mitigation and DR will be cMWh(power generation) (=c-dMWh(power generation)+dMWh(DR)).

[0038] Figure 8 shows an example of a coordinated operation plan flow for an example where the specific operational objectives of the shared adjustment capacity are grid congestion mitigation, imbalance avoidance, and DR. In step S701, the interconnected DER / shared adjustment capacity operation planning unit 104 converts input data 701, such as grid congestion information and DER supply and demand information, into a data format that allows for coordinated planning for the specific operational objectives, and saves it as setting data 702 in the database unit 107. In step S702, the interconnected DER / shared adjustment capacity operation planning unit 104 uses the setting data 702 to formulate a coordinated plan for the specific operational objectives in the same manner as described above, and creates the congestion mitigation coordinated plan 703, the imbalance avoidance coordinated plan 704, and the DR coordinated plan 705. With this configuration, it is possible to create coordinated plans for all of the specific operational objectives simultaneously.

[0039] Figure 9 shows a second example of the overall sequence of regional supply and demand management. In the overall sequence of regional supply and demand management shown in Figure 3, the process 202 for registering shared adjustment capacity with the regional supply and demand coordination platform 901 can also be performed based on the bidding information that the RA system 903 has submitted to the TSO system 904. For example, the DMS 902 aggregates at least the startup cost, minimum output cost, and marginal cost curve included in the bidding information for each area, and uses a portion of the bidding information to partition the capacity, and the resulting shared adjustment capacity is registered with the regional supply and demand coordination platform 901 in process 1001. The regional supply and demand coordination platform 901 creates a coordinated operation plan in the same manner as process 205, and notifies the DMS 902 and the RA system 903 of the coordinated operation plan in the same manner as process 206. The DMS 902 conducts a market bid taking the coordinated operation plan into account, and settles the obtained transaction revenue with the RA system 903 via the TSO system 904. By adopting this configuration, it becomes easy to dynamically change the capacity of the shared adjustment force obtained by the capacity division.

[0040] Figure 10 shows an example of the functional configuration of a power distribution congestion management system that extends the regional supply and demand coordination platform of the present invention. The power distribution congestion management system 801 may be referred to as a "power distribution congestion management device".

[0041] The power distribution congestion management system 801 comprises at least the shared adjustment power management unit 802, the DER supply and demand information acquisition unit 803, the interconnected DER / shared adjustment power operation planning unit 804, the plan notification unit 805, the external interface unit 806, the database unit 807, the congestion management unit 808, the market trading unit 809, and the system operation unit 810. Of these, functions not described in the above embodiment include: the congestion management unit 808 calculates congestion information based on supply and demand forecasts for the local grid and system control plans for system control equipment such as voltage and phase control equipment, and formulates power generation plans for DERs owned or operated by the DSO in accordance with the coordinated operation plan created by the interconnected DER / shared adjustment power operation planning unit 804. The market trading unit 809 creates bidding information for the power and adjustment power market, etc., in accordance with the power generation plan and conducts market transactions. The system operation unit 810 controls the DER in accordance with the power generation plan, monitors whether there is grid congestion in the distribution system, and implements measures such as remotely controlling the system control equipment and the interconnection DER if necessary.
