[0025] According to an embodiment of the present invention, a method for determining virtual resources for a two-tier electricity sharing transaction is provided. It should be noted that in the flowchart in the accompanying drawings, the steps shown therein can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in an order different from that shown here.

[0026] The following is an introduction to the method for determining virtual resources in a double-layer power sharing transaction according to an embodiment of the present invention.

[0027] Figure 1 is a flow chart of a method for determining virtual resources for a two-layer power sharing transaction according to an embodiment of the present invention. Figure 1 As shown, the method for determining virtual resources of the double-layer power sharing transaction may include the following steps:

[0028] Step S101, obtaining multiple participants in a two-layer power sharing transaction in a distribution network, and transfer virtual resources of the participants.

[0029] In the technical solution provided in the above step S101 of the present invention, multiple participants in the two-layer power sharing transaction in the distribution network and the transferred virtual resources of the participants can be obtained. The participants are power sales objects or power purchase objects, and the power sales objects or power purchase objects conduct power transactions with target participants other than the participants among the multiple participants.

[0030] Optionally, the two-layer power sharing transaction can be called an energy sharing transaction. The electricity seller can be called the electricity seller. The electricity buyer can be called the electricity buyer. The participating objects can be participating entities in the shared transaction platform in the distribution network, and the participating entities can be independent individuals in the energy sharing transaction in the shared transaction platform. The transferred virtual resources can be funds transferred to the participating objects, for example, multiple funds transferred to the participating entities are obtained, and can be transferred through (φ1, φ2, φ n ) is used to indicate.

[0031] For example, Figure 2 is a schematic diagram of an energy sharing transaction according to an embodiment of the present invention, such as Figure 2 As shown in the figure, the participants are independent individuals in the energy sharing transaction, including: new business entities, producers and sellers (including wind power producers and sellers and photovoltaic producers and sellers), electric vehicle clusters, energy storage, and distributed power sources. Assume that there are n participants, i = 1, 2,, n, N = {1, 2,, n}, these participants are rational and intelligent, and can interact in decision-making to gradually reach a collective decision. Furthermore, the power trading center can trade electricity or ancillary services with new business entities, power generation companies, power sales companies and power users.

[0032] Step S102: determining initial winning bid results of multiple participating objects based on multiple transferred virtual resources.

[0033] In the technical solution provided in step S102 of the present invention, after obtaining multiple transferred virtual resources, the initial winning results of multiple participating objects can be determined, wherein the initial winning results are used to characterize the winning status of the participating objects, and the initial winning results of multiple participating objects can be obtained by (y1, y2, y n ) is used to indicate.

[0034] For example, a typical scheme of energy cooperation between multiple buyers and sellers can be expressed as x = {y1, y2, ... y n ,φ1,φ2,…φ n}. Among them, (y1,y2,y n ) is used to indicate the winning situation of the participating entities; (φ1, φ2,…φn ) is used to represent the funds transferred to the participating entity. i > 0, it means that the funds obtained by entity i are φ i , in this case, i is the electricity seller; otherwise, it means that the funds spent by entity i are |φ i |, in this case i is the electricity buyer. The set X consisting of all feasible solutions is called the alternative solution set, and can be expressed as follows:

[0035]

[0036] It should be noted that this is only a preferred implementation method for determining the initial winning results of multiple participating objects, and does not specifically limit the process and method for determining the initial winning results of multiple participating objects. As long as the method and process for determining the initial winning results of multiple participating objects are based on multiple transferred virtual resources, they are within the protection scope of the present invention and will not be listed here.

[0037] Step S103, inputting the multiple initial bid-winning results into the bid-winning decision model of the participating objects for analysis, and obtaining the target bid-winning strategies of the multiple participating objects.

[0038] In the technical solution provided in the above step S103 of the present invention, after obtaining multiple initial winning bid results, the multiple initial winning bid results can be input into the winning bid decision model of the participating objects for analysis, so as to achieve the purpose of obtaining the target winning bid strategies of the multiple participating objects, wherein the target winning bid strategy is used to characterize the rules for allocating electric energy to the participating objects, and the winning bid decision model is used to construct the decision target by taking the objective function of the participating objects as the decision target, and the objective function is used to characterize the virtual resources that the participating objects expect to obtain in participating in the two-layer electric energy sharing transaction.

[0039] Optionally, the bidding decision model takes social welfare maximization as the objective function, and the decision variables are the actual winning amount of each participating entity and the degree of line network congestion. so It is the sum of the seller's surplus and the buyer's surplus, or the difference between the buyer's bid and the seller's asking price. However, when the prices of both parties are the same, it has no impact on social welfare, and in order to ensure the completion of such transactions, a penalty term f is added to the objective function. pu The energy storage collection in the shared transaction is represented by Ω ES represents, k is the index inside its set. Then the objective function can be expressed by the following formula:

[0040]

[0041] In the above formula, t is used as the time index to indicate the bidding period; T is used to indicate the total bidding period. k,t / ξ k,t / yk,t They are used to represent the bidding quantity, bidding price and winning situation of energy storage electricity trading. ε is a sufficiently small positive number, N B / N S Represents the total number of buyers and sellers respectively.

[0042] It should be noted that this is only a preferred implementation method for obtaining the target bidding strategy for multiple participating objects, and does not specifically limit the process and method for obtaining the target bidding strategy for multiple participating objects. As long as multiple initial bidding results are input into the bidding decision model for analysis, the process and method for obtaining the target bidding strategy are within the scope of protection of the present invention and will not be listed here.

[0043] Step S104, executing the target bidding strategy for the multiple participating objects to obtain the target bidding results of the multiple participating objects.

[0044] In the technical solution provided in the above step S104 of the present invention, the target bidding strategy can be executed on multiple participating objects so as to obtain the target bidding results of multiple participating objects, wherein the economic benefits generated by the multiple participating objects in the target bidding results are higher than the economic benefits generated by the multiple participating objects in the initial bidding results.

[0045] For example, after obtaining the target bidding strategy, the target bidding strategy can be executed on multiple participating entities to obtain the final bidding results of the multiple participating entities, so that the economic benefits generated by the multiple participating entities are the highest at this time.

[0046] Step S105: determining the target virtual resources of the participating object based on the target winning result.

[0047] In the technical solution provided in the above step S105 of the present invention, the target virtual resources of the participating object can be determined according to the above obtained target bid winning result, wherein the target virtual resources can be the economic benefits of the participating object.

[0048] Optionally, according to the target winning result, different target virtual resources corresponding to the object can be determined according to the different types of participation of the participating object. For example, when the participating subject is the electricity seller, the target virtual resource at this time is the income from selling surplus electric energy resources; when the participating subject is the electricity buyer, the target virtual resource at this time is the benefit obtained through the utility function.

[0049] It should be noted that this is only a preferred implementation method for determining the target virtual resources of the participating objects, and does not specifically limit the process and method for determining the target virtual resources of the participating objects. As long as the process and method for determining the target virtual resources of the participating objects are based on the target bidding results, they are within the protection scope of the present invention and will not be listed here.

[0050] In the above steps S101 to S105 of the present invention, multiple participants in the two-layer power sharing transaction in the distribution network and the transfer virtual resources of the participants can be first obtained. According to the multiple transfer virtual resources obtained above, the initial winning results of the multiple participants can be determined, and then the multiple initial winning results are input into the winning decision model of the participants for analysis, so as to obtain the target winning strategies of the multiple participants, and the target winning strategies are executed on the multiple participants to obtain the target winning results of the multiple participants, and finally according to the target winning results obtained above, the target virtual resources of the participants can be determined. Considering that after obtaining the transfer virtual resources of the participants, the initial winning results of the multiple participants can be determined according to the multiple transfer virtual resources, and then the initial winning results obtained above are input into the winning decision model of the participants for analysis, the target winning strategies can be obtained, and the target winning strategies are executed on the multiple participants to achieve the acquisition of the target winning results, and the purpose of determining the target virtual resources of the participants is achieved, so as to solve the technical problem that the participants cannot effectively determine the virtual resources in the two-layer power sharing transaction, and achieve the technical effect that the participants can effectively determine the virtual resources in the two-layer power sharing transaction.

[0051] The above method of this embodiment is further introduced below.

[0052] As an optional implementation method, based on multiple transferred virtual resources, initial winning bid results of multiple participating objects are determined, including: classifying the multiple participating objects separately to obtain classification results, wherein the classification results are used to characterize the participating objects as new business participating objects, or participating objects other than new business participating objects; based on the classification results and the transferred virtual resources, the initial winning bid results are determined.

[0053] In this embodiment, after obtaining a plurality of participating objects, the plurality of participating objects may be classified to obtain a classification result, and then the initial winning bid result may be determined according to the classification result and the transferred virtual resources.

[0054] Optionally, the multiple participants are divided into two categories as a whole, one is new business participants, and the other is other participants except the new business participants.

[0055] Optionally, according to different classification results of multiple participating objects and the transferred virtual resources corresponding to the participating objects, the initial winning bid result is obtained through different calculation methods.

[0056] As an optional implementation method, the initial winning bid result is determined based on the classification result and the transfer of virtual resources, including: in response to the classification result that the participant is a new type of business participant, obtaining a first electricity trading declaration amount of the new type of business participant and a second electricity trading declaration amount of the new type of business participant, wherein the first electricity trading declaration amount is greater than the second electricity trading declaration amount; determining the difference in electricity trading declaration amount between the first electricity trading declaration amount and the second electricity trading declaration amount as the first bid value of the new type of business participant; determining the initial winning bid result based on the first bid value and the transfer of virtual resources.

[0057] In this embodiment, after obtaining the classification result, if the classification result is that the participant is a new type of business participant, it is necessary to obtain the first power transaction declared amount of the new type of business participant and the second power transaction declared amount of the new type of business participant, and then determine the power transaction declared amount difference between the first power transaction declared amount and the second power transaction declared amount as the first bid value of the new type of business participant, and according to the first bid value obtained above and the transferred virtual resources, the purpose of determining the initial winning bid result can be achieved. Among them, the new type of business participant can be called a new type of business entity.

[0058] Optionally, the first electric energy transaction declaration amount may be the electric energy transaction declaration amount for all services performed by the new business participant, and The second electric energy transaction declaration amount can be the electric energy transaction declaration amount for the new type of business participant to perform auxiliary services, and through The first bid value can be expressed by P NM,t To express.

[0059] For example, given that the new business entity has dual-role attributes, its type in the shared transaction is related to its power application volume in the power service and ancillary service markets. The bid value P of the new business entity is NM,t It can be expressed by the following formula:

[0060]

[0061] As an optional implementation method, the initial winning bid result is determined based on the classification result and the transfer of virtual resources, including: in response to the classification result that the participating object is other participating objects, the target operating state and power supply and demand information of the other participating objects are obtained, wherein the target operating state is that the other participating objects are in a normal operating state; based on the target operating state and the power supply and demand information, the bidding signals of the other participating objects are determined, wherein the bidding signals are used to characterize the bidding values ​​of the transaction volume and the bidding values ​​of the transaction value attributes generated by the other participating objects when conducting power transactions; in response to the bidding signals, the initial winning bid result is determined based on the transfer of virtual resources.

[0062] In this embodiment, if the classification result is that the participating object is another participating object, the target operating state and power supply and demand information of the other participating object can be obtained, and then the bidding signal of the other participating object can be determined based on the above-obtained target operating state and power supply and demand information, and the bidding value of the participating object can be determined based on the bidding signal, and the initial winning bid result can be determined based on the bidding value and the transferred virtual resources. Among them, the power supply and demand information includes the power supply and demand relationship of the participating object itself.

[0063] Optionally, the bidding signal can be expressed by θ i It is represented by i = {P i ,ξ i}, in the above formula, P i It is used to represent the bid value of subject i for the transaction volume. When P i > 0, entity i is the electricity seller, otherwise when P i When <0, entity i is the electricity purchaser. i It is used to represent the bid value of subject i for the transaction electricity price. Subject i knows its own θ i , but other subjects do not know the value of θ i So the value of θ i The type of the subject is called.

[0064] As an optional implementation method, multiple initial bidding results are input into the bidding decision model of the participating objects for analysis to obtain target bidding strategies for multiple participating objects, including: based on multiple initial bidding results, using the first constraint condition, the second constraint condition and the third constraint condition of the participating objects to constrain the bidding decision model to obtain the target bidding strategy, wherein the first constraint condition is used to constrain the electricity trading volume of the participating objects, the second constraint condition is used to constrain the transmission capacity of the lines in the area where the participating objects are located, and the third constraint condition is used to constrain the energy storage power of the participating objects.

[0065] In this embodiment, based on multiple initial bid-winning results, the first constraint condition, the second constraint condition and the third constraint condition of the participating objects can be used to constrain the bid-winning decision model, so as to achieve the purpose of obtaining the target bid-winning strategy.

[0066] Optionally, the first constraint condition may be referred to as a constraint condition on the cumulative transaction volume of the buyer and seller. For example, the first constraint condition ensures that the cumulative transaction volume of the buyer and seller does not exceed the amount declared by the buyer and seller, and may be represented by the following formula:

[0067]

[0068]

[0069] Among them, P bs,t It is used to indicate the amount of electricity sold by the seller s to the buyer b at time t. It is used to indicate the amount of electricity sold by the energy storage to the buyer b at time t. b,t Used to indicate the electricity quantity declared by buyer b at time t. It is used to represent the amount of electricity sold by the energy storage to the seller s at time t. s,t Used to indicate the electricity quantity reported by seller s.

[0070] Optionally, the second constraint condition may be referred to as a line transmission constraint condition, which is expressed by the following formula:

[0071]

[0072]

[0073] In the above formula, f lt is the transmission capacity of line l at time t, is the maximum transmission capacity of line l. sl,t / T bl,t / T kl,t They are used to represent the allocation factors of the lines. Since the present invention only considers radial networks, they can be taken as {0,1}. sl,t For example, when line l is on the line of the transaction pair consisting of individual bs or bk, it is 1, otherwise it is 0.

[0074] Optionally, the third constraint condition may be referred to as a constraint condition for energy storage operation, and is expressed by the following formula:

[0075]

[0076]

[0077]

[0078] In the above formula, can be expressed as the minimum capacity and maximum capacity of energy storage k, respectively. It is used to represent the amount of electricity purchased by energy storage k from the grid, Q k,t-1 Used to indicate the amount of energy stored k at time t-1.

[0079] As an optional implementation manner, based on the target bid winning result, the target virtual resources of the participating object are determined, including: inputting the target bid winning result into the settlement model of the participating object for analysis to obtain the target virtual resources.

[0080] In this embodiment, after obtaining the target winning result, the target winning result can be input into the settlement model of the participating object for analysis, so as to obtain the target virtual resource. The target virtual resource can be used to represent the total benefit of the participating object at this time, which can be determined by the total funds transferred to the participating object. For example, the amount of money φ transferred to subject i i It is expressed as the total benefit of all other agents in the optimal bidding situation when agent i appears minus the total benefit of all other agents in the optimal bidding situation when agent i does not appear.

[0081] Optionally, the settlement model may be referred to as a specific model of the fund settlement stage, and may be represented by the following formula:

[0082]

[0083] In the above formula, It is used to represent the sum of the optimal benefits of all agents when all agents participate in energy mutual assistance, y * It is used to represent the best winning situation when the type of each agent is θ. i (y i * ,θ i ) is used to represent the benefits of agent i in the best bid winning situation, including the benefits of the services provided by agent i to other agents and its own operating costs. It is used to represent the sum of the optimal benefits of each agent after removing agent i, y -i * It means that after dividing i, the types of agents are θ -i The best winning bid situation is obtained by optimizing the winning bid decision model of shared operation with network congestion.

[0084] Optionally, in response to the participant being a power selling object and the first target winning result of the target winning result, the target virtual resource is determined to be the first target virtual resource; in response to the participant being a power purchasing object and the second target winning result of the target winning result, the target virtual resource is determined to be the second target virtual resource using the virtual resource function. The virtual resource function may be called a Cobb-Douglas utility function.

[0085] For example, in addition to new business entities, when the participating entity is the electricity seller in the energy sharing transaction, its benefit is the income from selling surplus electric energy resources, and can be expressed by the following formula:

[0086]

[0087] In the above formula, Ω B Used to represent the set of electricity buyers in energy sharing transactions.bs Used to indicate the amount of electricity purchased by electricity buyer b from electricity seller s. It can be used to indicate the total amount of electricity purchased from electricity purchasing direction s.

[0088] For another example, when the participating entity is the electricity buyer in the energy sharing transaction, the Cobb-Douglas utility function is used to express its benefits; when the electricity buyer is a producer or electric vehicle cluster, its necessary electricity demand is considered to obtain the dissatisfaction cost when resources are not matched, and it can be expressed by the following formula:

[0089]

[0090] In the above formula, Ω S It can be used to represent the set of electricity sellers in energy sharing transactions. It can be used to represent the total amount of electricity sold in the electricity sales direction b. A can be used to represent the comprehensive technical level constant, which is 1. β can be used to represent the output elasticity coefficient of labor. μ can be used to represent random interference information; ES, EV, and Pro represent energy storage, electric vehicle clusters, and producers and sellers, respectively.

[0091] As an optional implementation mode, the method also includes: determining the participation type of the participating object based on the transferred virtual resources; in response to the resource amount corresponding to the transferred virtual resources being a positive number, determining the participation type as a power selling object; in response to the resource amount corresponding to the transferred virtual resources being a negative number, determining the participation type as a power purchasing object.

[0092] In this embodiment, after obtaining the transferred virtual resources, the participation type of the participating object can be determined according to the numerical value corresponding to the transferred virtual resources. If the amount of resources corresponding to the transferred virtual resources is a positive number, the participating object at this time can be determined to be a power selling object; if the amount of resources corresponding to the transferred virtual resources is a negative number, the participating object at this time can be determined to be a power purchasing object. The amount of resources corresponding to the transferred virtual resources can be represented by a numerical value.

[0093] For example, if we transfer virtual resource φ i > 0, it means that the funds obtained by entity i are φ i , in this case, i is the electricity seller; otherwise, it means that the funds spent by entity i are φ i , in this case, i is the electricity purchaser. It should be noted that this is only a preferred implementation method for determining the participation type of the participating object, and does not specifically limit the process and method for determining the participation type of the participating object.

[0094] In this embodiment, multiple participants in the two-layer power sharing transaction in the distribution network and the transfer virtual resources of the participants can be obtained first. According to the multiple transfer virtual resources obtained above, the initial winning results of the multiple participants can be determined, and then the multiple initial winning results are input into the winning decision model of the participants for analysis, so as to obtain the target winning strategies of the multiple participants. The target winning strategies are executed on the multiple participants, and the target winning results of the multiple participants can be obtained. Finally, according to the target winning results obtained above, the target virtual resources of the participants can be determined. Considering that after obtaining the transfer virtual resources of the participants, the initial winning results of the multiple participants can be determined according to the multiple transfer virtual resources, and then the initial winning results obtained above are input into the winning decision model of the participants for analysis, the target winning strategies can be obtained, and the target winning strategies are executed on the multiple participants to achieve the acquisition of the target winning results, and the purpose of determining the target virtual resources of the participants is achieved, so as to solve the technical problem that the participants cannot effectively determine the virtual resources in the two-layer power sharing transaction, and achieve the technical effect that the participants can effectively determine the virtual resources in the two-layer power sharing transaction.

[0095] The technical solution of the embodiment of the present invention is illustrated below in conjunction with preferred implementation modes.

[0096] With the continuous development of new power systems, the proportion of traditional hydropower and thermal power units has gradually decreased. The control mode of the power system that relies on the flexible adjustment capability of conventional units faces the difficulty of insufficient adjustable resources. It is necessary to tap more flexible resources that can support the power grid to maintain the safe operation of the power system itself.

[0097] In terms of decentralized heterogeneous resource operation strategies, traditional methods have conducted a lot of research on energy sharing in energy storage, electric vehicles, microgrids, multi-energy systems, virtual power plants, etc. According to the external characteristics of flexible resources, flexible resources of different types have different service capabilities. However, with the increase in the demand for massive distributed new energy access and user types, coupled with the continuous development of energy Internet technology, heterogeneous entities can improve their operational efficiency under the benefit-sharing-risk-sharing decision-making method.

[0098] In the process of distributing electricity to operators, it is often achieved through an electricity sharing transaction mechanism. However, the above method does not share the individual operator's benefit deviation among other individuals within the distribution network, resulting in the phenomenon that the actual shared costs cannot be fully shared or are over-allocated, which in turn leads to the technical problem that the participants cannot effectively determine the virtual resources in the two-tier electricity sharing transaction.

[0099] Therefore, in order to solve the above problems, the present invention proposes a method for determining a two-tier transaction model for a new type of operating entity with adjustable resources. The method is operated in a shared transaction center, and the transaction price and matching rules of the shared service market in the region are determined according to the adjustment needs of each entity and the shared market electricity price information, so as to ensure the fairness of electricity transactions between various entities. The shared transaction platform conducts two rounds of quotations and resource matching for the same period of time to clarify the price signal. In order to effectively reflect the differences between various individuals in terms of adjustment demand and service capabilities, the principle of "whoever provides services will get the benefits" and "whoever gets the benefits will bear the costs" is followed to distinguish the characteristics of various resources through different quotation quantities, and taking into account the impact of line transmission capacity on adjustment costs and the impact of adjustment service capabilities on benefits, a flexible adjustable resource sharing operation value distribution mechanism is proposed, which mainly includes three stages: bidding, winning bid decision, and financial settlement.

[0100] Optionally, during the bidding phase: e.g. Figure 2 As shown in the figure, the participants are independent individuals in energy sharing transactions, including new business entities, producers and sellers, electric vehicle clusters, energy storage, and distributed power sources; the strategy set is a typical solution for energy mutual assistance between multiple buyers and sellers, and the collection of all feasible solutions is called the alternative solution set. Before making a collective decision, various resources know their transaction volume and transaction price preferences in the sharing transaction, which can be regarded as the subject determining its bidding signal by observing its own power supply and demand relationship and operation status.

[0101] Optionally, in the bidding decision stage: the bidding decision model takes the maximization of social welfare as the objective function, the decision variable is the actual winning bid of each subject and takes into account the line network congestion, and the social welfare in the objective function is the sum of the seller's surplus and the buyer's surplus, which can also be expressed as the difference between the buyer's bid and the seller's asking price. The shared operation bidding decision model also has constraints such as the cumulative transaction volume of the buyer and seller does not exceed their own declared volume, line transmission constraints, and energy storage operation constraints.

[0102] Optionally, in the fund settlement stage: fund settlement is performed based on the Clarke mechanism, and the amount of money transferred to subject i is expressed as the total benefit of all other subjects in the optimal bidding situation when subject i appears minus the total benefit of all other subjects in the optimal bidding situation when subject i does not appear; mathematical modeling is used to calculate the individual benefits of new operating entities. Except for the new operating entities, when the participating entities are electricity sellers in energy sharing transactions, their benefits are the income from selling surplus electric energy resources; when the participating entities are electricity buyers in energy sharing transactions, the Cobb-Douglas utility function is used to represent their benefits.

[0103] Optionally, the bidding stage includes: determining the participating entities, strategy sets and participation types of the participating entities, wherein the participating entities are determined: the participating entities are independent individuals in the energy sharing transaction, including: new business entities, producers and sellers (including wind power producers and sellers and photovoltaic producers and sellers), electric vehicle clusters, energy storage, and distributed power sources. Assume that there are n participating entities, i = 1, 2,, n, N = {1, 2,, n}, these participating entities are rational and intelligent, and can interact in decision-making to gradually reach a collective decision. Further, the power trading center can conduct power transactions with new business entities, power generation companies, power sales companies and power users.

[0104] Optionally, determine a strategy set: A typical solution for energy mutual assistance between multiple buyers and sellers can be expressed as x = {y1, y2, ... y n ,φ1,φ2,…φ n}. Among them, (y1,y2,…y n ) is used to indicate the winning situation of the participating entities; (φ1, φ2,…φ n ) is used to represent the funds transferred to the participating entity. i > 0, it means that the funds obtained by entity i are φ i , in this case, i is the electricity seller; otherwise, it means that the funds spent by entity i are φ i , in this case i is the electricity buyer. The set X consisting of all feasible solutions is called the alternative solution set, and can be expressed as follows:

[0105]

[0106] Optionally, determine the participation type of the participating subject: before making a collective decision, each resource knows its transaction volume and transaction price preference in the shared transaction, which can be regarded as subject i determining its bidding signal θ by observing its own power supply and demand relationship and operation status i , and θ i = {P i ,ξ i}. Among them, P i It is used to represent the bid value of subject i for the transaction volume. When P i > 0, entity i is the electricity seller, otherwise when P i When <0, entity i is the electricity purchaser. i It is used to represent the bid value of subject i for the transaction electricity price. Subject i knows its own θ i , but other subjects do not know the value of θ i So the value of θ i The type of the subject is called.

[0107] Optionally, given that the new business entity has dual-role attributes, its type in the shared transaction is related to its power application volume in the power service and ancillary service markets. The bid value P of the new business entity is NM,t It can be expressed by the following formula:

[0108]

[0109] In the embodiment of the present invention, the bidding decision stage includes: the bidding decision model takes social welfare maximization as the objective function, and the decision variables are the actual winning amount of each participating entity and the line network congestion degree. so It is the sum of the seller's surplus and the buyer's surplus, or the difference between the buyer's bid and the seller's asking price. However, when the prices of both parties are the same, it has no impact on social welfare, and in order to ensure the completion of such transactions, a penalty term f is added to the objective function. pu The energy storage collection in the shared transaction is represented by Ω ES represents, k is the index inside its set. Then the objective function can be expressed by the following formula:

[0112] Optionally, the winning bid decision model can be constrained by three constraints, namely, the constraint condition of the cumulative transaction volume of the buyer and seller, the constraint condition of line transmission and the constraint condition of energy storage operation. Among them, the constraint condition of the cumulative transaction volume of the buyer and seller means that the cumulative transaction volume of the buyer and seller does not exceed the amount declared by themselves, and can be expressed by the following formula:
