[0051] In order to make the purpose, technical scheme and advantages of the embodiments of the present invention clearer, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. It should be noted that the embodiments in this application and the features in the embodiments can be combined with each other arbitrarily without conflict.

[0052] As the proportion of renewable energy (such as wind power and photovoltaic power) connected to the power system continues to increase, the costs on the power supply side, grid side, load side and energy storage side will also change to varying degrees. The uncertainty of renewable energy output will lead to the need for additional backup and operating costs in system scheduling. How to fairly and reasonably share this cost within the new power system has become one of the important issues that need to be studied for large-scale renewable energy access and consumption.

[0053] Therefore, in response to the uncertainty of wind power and photovoltaic power generation in the power system, the increased standby costs can be reasonably shared among the wind farms. On the basis of minimizing the total cost of system operation, the interests of the source, network, load and storage parties should be fully considered. It is necessary to redistribute the interests of all parties within the power system fairly and effectively in accordance with the principle of how to achieve economical and efficient cost allocation among the various entities in the new power system.

[0054] An embodiment of the present invention discloses a method for distributing benefits in an electric power system. The method in this embodiment requires the use of the Shapley value method during implementation. In order to better illustrate the method in the present invention, the Shapley value method is firstly described.

[0055] The Shapley value method is a common method for solving multi-person cooperative game problems and is widely used in the problem of profit distribution among multiple enterprises. In cooperation, different interest individuals may be affected by different external factors. If the profit distribution is carried out according to the average sharing, it is obviously unreasonable for the subject with the largest influencing factors. The alliance after distribution may be unstable and each subject may withdraw from the alliance. In view of this, the present invention proposes a profit distribution method for power system. The improved Shapley value method considering environmental protection factors is used to redistribute the benefits of cooperative games, so that each cooperative alliance remains stable.

[0056] like Figure 1 As shown, the method in this embodiment includes the following steps:

[0057] S101, constructing a first cost allocation model, the first cost allocation model is established based on the Shapley value method, and the first cost allocation model includes multiple stakeholders;

[0058] The first cost sharing model is established based on the traditional Shapley value method. The Shapley value method is a method used to solve individual cooperative game problems. It can be directly used to solve the problem of cost sharing among various entities. The benefits are distributed according to the size of each stakeholder's marginal contribution to the alliance, so that each entity can obtain more benefits than when it does not join the alliance. However, the traditional Shapley value method is an equal distribution plan.

[0059] The traditional Shapley value method does not take into account the external factors that the relevant entities that distribute benefits bear in the actual game process of forming an alliance. Therefore, in the process of constructing a new power system cost sharing model, the impact of external factors should be comprehensively weighed, and environmental protection should be included in the cost sharing of the new power system to ensure the healthy and sustainable development of the new power system.

[0060] The first cost-sharing model includes multiple stakeholders, including the power supply side, grid side, load side and energy storage side, namely power generation companies, grid companies, demand-side aggregators and energy storage companies.

[0061] The corresponding first cost allocation model is constructed from four aspects: power generation enterprises, power grid enterprises, demand-side aggregators, and energy storage enterprises. The Shapleya value allocation method is constructed as follows:

[0062] The stakeholders of the new power system involved in cost sharing are regarded as the basic elements of the cooperative game problem, including decision makers and characteristic functions, which are mathematically expressed as (N, v), where N = {1, 2, 3...n} represents the decision maker set, that is, the number of stakeholders involved in cost sharing in the new power system, and N is a positive integer, n is the number of decision makers involved in decision-making, and v represents the characteristic function of this alliance. S represents the alliance between decision makers, that is, S is a cooperative alliance of N, s is the number of decision makers in coalition S.

[0063] Assume that a coalition A is formed by any decision makers in the set N, satisfying The decision makers in Alliance A work together to maximize the benefits of the alliance, and v represents the value benefit obtained by Alliance A. At this time, the characteristic function is defined as the function that represents the common benefits of the alliance, that is, v s is the characteristic function of the alliance S, and when A=S, v is equal to v s .

[0064] Assume that N is the set of decision makers participating in the decision-making under the cooperative game; S represents a cooperative alliance of N; s represents the number of decision makers under alliance S. Assume that all decision makers form alliances in a random order, and the probability of forming each alliance is p, and the calculation formula of p is as follows:

[0065]

[0066] Among them, p is the probability of each alliance, and n is the total number of decision makers involved in the alliance.

[0067] Decision maker i and other (s-1) decision makers form a coalition S. There are (s-1)! (ns)! combinations. Then, the probability of coalition S containing decision maker i is set to The calculation formula is as follows:

[0068]

[0069] in, is the probability of the coalition S containing decision maker i appearing, s is the number of decision makers in the coalition S, and n is the total number of decision makers participating in the coalition.

[0070] In the coalition S, the marginal contribution of decision maker i is r i , and its calculation formula is as follows:

[0071] r i =v s -v s / i

[0072] Among them, r i is the marginal contribution value of decision maker i in alliance S, v s is the value benefit obtained by the decision makers in the alliance S, v s / i is the value benefit when the remaining (s-1) decision makers excluding decision maker i form an alliance.

[0073] The Shapley value allocation method is the expected value of the contribution made by the decision makers participating in the cooperative game in the alliance. The calculation formula is as follows:

[0074]

[0075] Among them, π i (N,v) is the benefit value allocated to decision maker i, s is the number of decision makers in the alliance S, n is the total number of decision makers participating in the alliance, and v s is the value benefit obtained by the decision makers in the alliance S, v s / i is the profit when the remaining (s-1) decision makers excluding decision maker i form an alliance.

[0076] In the payment transfer cooperative game (N, v) scenario, when allocating the benefit value, under this alliance, the distribution strategy of the benefit value of the relevant decision makers can be used to allocate the payment to (x1,…,x i ,…,x n ) to indicate that x i is the benefit value allocated to decision maker i.

[0077] The decision maker's benefit value distribution strategy must meet certain constraints, which are individual rationality and overall rationality.

[0078] Individual rationality means that the benefit value distributed to each decision maker participating in the alliance is not less than the benefit value of independent decision making. Its mathematical expression is as follows:

[0079] x i ≥v i

[0080] Among them, x i is the benefit value of decision maker i participating in the alliance, v i is the benefit value of decision maker i’s independent decision.

[0081] Overall rationality means that the total benefit value of the decision makers participating in the alliance is equal to the total benefit value of the alliance. Its mathematical expression is as follows:

[0082]

[0083] Among them, x i is the benefit value of decision maker i participating in the alliance, n is the number of decision makers participating in the alliance, v N is the total revenue value of alliance N.

[0084] S102, determining an environmental protection correction coefficient of each stakeholder based on the environmental protection contribution of each stakeholder, wherein the environmental protection contribution is related to the environmental protection input cost of the stakeholder.

[0085] In the cost allocation of various entities in the power system, the traditional Shapley value method mainly allocates the costs of various entities in the power system from the perspective of cost minimization, and does not consider the cost allocation between various entities from the perspective of environmental protection. However, with the development of new power systems, it is possible to truly reflect the impact of environmental protection on the cost allocation of various entities in the new power system under the premise of cost minimization.

[0086] Environmental protection is incorporated into the consideration of benefit distribution of new power systems. The main measurement indicator for measuring the contribution of different stakeholders to environmental protection factors is the environmental protection investment cost of the relevant stakeholders. However, the specific environmental protection effect is also related to the resource utilization effect and the interests of the stakeholders themselves. For example, the environmental protection effect of thermal power units is not only related to the investment cost of their environmental protection equipment, but also to other factors such as their fuel quality and operating status. Therefore, the environmental protection contribution needs to be calculated according to the actual situation of different stakeholders, and the environmental protection correction coefficient of each stakeholder is determined according to the calculated environmental protection contribution.

[0087] S103, obtaining an environmental protection weight parameter of each stakeholder, wherein the environmental protection weight parameter is related to the environmental protection correction coefficient.

[0088] Exemplarily, the environmental weight parameter corresponding to the environmental correction coefficient is obtained according to the evaluation results of the relevant experts on the compensation factors of the environmental protection factors of each stakeholder.

[0089] S104, based on the environmental weight parameter and the environmental correction coefficient, correct the value allocation result determined based on the first cost allocation model to obtain a corrected value allocation result.

[0090] Exemplarily, the value distribution result determined by the first cost allocation model is corrected based on the calculated environmental protection correction coefficient and the judged environmental protection correction coefficient to obtain the corrected value distribution result of each stakeholder.

[0091] The benefit distribution method of the power system provided by the present invention fully considers the interests of the power supply side, the power grid side, the load side, and the energy storage side on the basis of minimizing the total cost of system operation, follows the principle of realizing economical and efficient cost allocation among various interest subjects of the new power system, and uses the modified Shapley value to realize fair and effective cost sharing among various parties within the power system from the aspect of environmental protection.

[0092] As an optional implementation of the present invention, the environmental protection contribution is set as the product of the relative environmental protection investment of the stakeholder and the environmental protection contribution coefficient of the stakeholder; wherein the relative environmental protection investment is related to the environmental protection investment cost, and the environmental protection contribution coefficient is related to the resource utilization effect of the stakeholder and the stakeholder's own attributes, specifically including:

[0093] Assume that there are n stakeholders in the new power system, and the environmental protection contribution of stakeholder i is The main indicator for measuring the contribution of different stakeholders to environmental protection is the environmental protection input cost of the relevant subjects. However, the specific environmental protection effect is also related to the resource utilization effect and the attributes of the stakeholders themselves. For example, the environmental protection effect of thermal power units is not only related to the investment cost of their environmental protection equipment, but also to other factors such as their fuel quality and operating status. Therefore, the environmental protection contribution needs to be calculated according to the actual situation of different subjects. The calculation formula is as follows:

[0094]

[0095] in, is the environmental protection contribution of stakeholder i, p i is the relative environmental protection investment of stakeholder i, e i is the environmental protection contribution coefficient of stakeholder i.

[0096] As an optional implementation mode of the present invention, based on the environmental protection contribution of each stakeholder, the environmental protection correction coefficient of each stakeholder is determined, specifically including:

[0097] Obtain the sum of the environmental protection contributions of multiple stakeholders;

[0098] Determine the average value of the environmental protection contribution of each stakeholder;

[0099] The difference between the quotient of the environmental protection contribution of the stakeholder and the total contribution and the average value and the product of the environmental value of the new power stakeholder are taken as the environmental protection correction coefficient.

[0100] For example, the sum of the environmental protection contributions of multiple stakeholders is The quotient of the environmental protection contribution of interest subject i and the total contribution is The average value of the environmental protection contribution of each stakeholder is The environmental protection correction coefficient can compare the environmental protection contribution of each stakeholder i with the average level. The calculation formula is as follows:

[0101]

[0102] Among them, β i is the environmental protection correction coefficient of interest subject i, π env The environmental value of the new power interest entity, p i is the relative environmental protection investment of stakeholder i, e i is the environmental protection contribution coefficient of stakeholder i, and n is the total number of stakeholders participating in the alliance.

[0103] As an optional implementation manner of the present invention, the environmental protection correction coefficient is positively correlated with the corrected value allocation result.

[0104] As an optional implementation mode of the present invention, the environmental protection correction coefficient is positively correlated with the corrected value allocation result, including:

[0105] When the environmental protection correction coefficient is positive, the interest subject obtains additional benefit distribution value due to its environmental protection contribution;

[0106] When the environmental protection correction coefficient is negative, the stakeholder's additional benefit distribution value is reduced due to the reduction of environmental protection contribution.

[0107] For example, it can be seen from the calculation formula of the environmental protection correction coefficient that when When , the environmental protection correction coefficient is positive, and the interest subject i will obtain additional benefit distribution value due to its good environmental protection contribution; when When , the environmental protection correction coefficient is negative, and the interest subject i will reduce the additional benefit distribution value due to its unprominent environmental protection contribution.

[0108] As an optional implementation of the present invention, based on the environmental weight parameter and the environmental correction coefficient, the value allocation result determined based on the first cost allocation model is corrected to obtain the corrected value allocation result, including:

[0109] Determining an initial value allocation result based on a first cost allocation model;

[0110] Determine the product of the environmental protection weight parameter and the environmental protection correction coefficient;

[0111] The sum of the initial value allocation result and the product of the environmental protection weight parameter and the environmental protection correction coefficient is taken as the revised value allocation result.

[0112] For example, in the first cost allocation model of the new power system, environmental protection is incorporated into the Shapley value method, and a value compensation mechanism based on the improved Shapley value is designed. The calculation steps are as follows:

[0113] The initial distribution value π of each stakeholder is obtained through the traditional Shapley value method of the first cost allocation model i According to the evaluation results of relevant experts on the compensation factors of the environmental protection factors of the stakeholders, the weight α corresponding to the environmental protection correction coefficient β is obtained, so that the product αβ of the environmental protection weight parameter and the environmental protection correction coefficient of each stakeholder can be determined. i , based on the environmental weight parameter and the environmental correction coefficient, the traditional Shapley value distribution benefits are corrected. The sum of the initial value distribution result and the product of the environmental weight parameter and the environmental correction coefficient is taken as the corrected value distribution result. The corrected distribution value of each interest subject is obtained. The calculation formula is as follows:

[0114]

[0115] in, is the revised interest value of interest subject i, π i is the initial allocation value of stakeholder i, β i is the environmental protection correction coefficient of interest subject i, and α is the correction weight corresponding to the environmental protection correction coefficient β.

[0116] Among them, the revised interest distribution method still needs to meet overall rationality, that is, to ensure that the total value allocated to each stakeholder according to the revised distribution method is equal to the total value allocated to each stakeholder before the revision.

[0117] As an optional implementation manner of the present invention, the multiple stakeholders include a power supply side, a grid side, a load side and an energy storage side.

[0118] As the proportion of renewable energy connected to the power system continues to increase, the costs on the power supply side, grid side, load side and energy storage side will also change to varying degrees. The uncertainty of renewable energy output will require system dispatch to increase additional backup and operating costs.

[0119] The cost allocation method using the Shapley value method takes into account the impact of large-scale access of renewable energy on the cost of the new power system. After the cost generated after the access of new energy is allocated to the power supply side, grid side, load side, and energy storage side, the cost paid by each entity is still lower than the cost of non-cooperation, which verifies the rationality of the Shapley value correction allocation method. By considering the impact of environmental protection on the cost sharing of each entity, it better mobilizes the attention of each entity to the national environmental protection policy in the process of building a new power system. Each entity can further reduce the operating cost of the new power system by regulating environmental protection technologies, etc., and realizes the fairness and effectiveness of cost sharing among various stakeholders within the power system, which can promote the investment and development of various entities in environmental protection in the future construction of new power systems.

[0120] On the basis of the traditional Shapley value method of the first cost allocation model, the quantitative analysis is further considered from the perspective of environmental protection, and is applied to the benefits distributed to various stakeholders in the power system. The logic is coherent and clear, and the plasticity is strong. It can be combined with computer technology to realize the benefit distribution through computers. At the same time, the cost allocation value can be collected and improved, and it has strong scalability. It can be linked with other algorithms in the future, laying a good foundation for jointly studying reasonable benefit distribution methods for power systems.

[0121] The embodiment of the present invention also discloses a benefit distribution device for an electric power system, such as Figure 2 As shown, the device comprises:

[0122] A construction module 201 is used to construct a first cost allocation model, the first cost allocation model is established based on the Shapley value method, and the first cost allocation model includes multiple stakeholders;

[0123] A determination module 202 is used to determine the environmental protection correction coefficient of each stakeholder based on the environmental protection contribution of each stakeholder, wherein the environmental protection contribution is related to the environmental protection input cost of the stakeholder;

[0124] An acquisition module 203 is used to acquire an environmental protection weight parameter of each stakeholder, wherein the environmental protection weight parameter is related to an environmental protection correction coefficient;

[0125] The correction module 204 is used to correct the value allocation result determined based on the first cost allocation model based on the environmental weight parameter and the environmental correction coefficient to obtain a corrected value allocation result.

[0126] The benefit distribution device of the power system provided by the present invention fully considers the interests of the power supply side, the power grid side, the load side, and the energy storage side on the basis of minimizing the total cost of system operation, follows the principle of realizing economical and efficient cost allocation among the various stakeholders of the new power system, comprehensively considers the cost of the power system and the environmental protection of each stakeholder, and while minimizing the cost of the power system, increases the proportion of the impact of environmental protection on the cost sharing of the subject, so that each subject bears the cost increase brought by environmental protection to the new power system as a whole to varying degrees. By quantifying the impact of environmental protection on the cost of the new power system into the cost sharing process, the factors for the cost sharing of the new power system are considered more comprehensively, and the sharing results are more objective and fair, which can promote the investment and development of various subjects in environmental protection during the construction of the future new power system.
