Description
Technical Field
[0001] This invention relates to the field of wind and solar pumped storage technology, specifically to capacity configuration methods, devices, equipment, media, and products for wind and solar pumped storage. Background Technology
[0002] With the advancement of energy transition, large-scale grid connection of new energy sources (wind and solar power) has become a trend. However, wind and solar power generation is characterized by intermittency and volatility, posing a severe challenge to the stable operation of the power system. Pumped storage, as a technologically mature and economically feasible energy storage method, possesses the ability to respond quickly and regulate large capacity. Therefore, the coordinated development of pumped storage and new energy sources (wind and solar power) has become a key path for building a new type of power system.
[0003] In the coordinated development of pumped hydro storage with wind and solar energy, capacity configuration is necessary to ensure better collaboration among these energy sources. Related technologies typically treat pumped hydro storage, wind energy, or solar energy as a single entity, determining the capacity configuration scheme for each. However, during the collaboration between pumped hydro storage and wind / solar energy, the interactions between these entities also affect capacity configuration. Therefore, determining the capacity configuration scheme for each entity individually results in inaccurate schemes that do not reflect reality. Summary of the Invention
[0004] In view of this, the present invention provides a method, apparatus, equipment, medium and product for capacity configuration of wind and solar pumped storage, in order to solve the problem that the capacity configuration schemes in related technologies are not accurate enough and do not conform to the actual situation.
[0005] In a first aspect, the present invention provides a capacity configuration method for wind-solar pumped storage in related technologies, comprising: randomly generating multiple initial capacity configuration schemes based on the capacity configuration parameters of the wind-solar pumped storage system; the wind-solar pumped storage system is a system in which wind-solar power plants, pumped storage power plants, and regional power grids operate in coordination; the wind-solar power plants, pumped storage power plants, and regional power grids are regarded as a cooperative alliance, and the target total revenue corresponding to the cooperative alliance under each initial capacity configuration scheme is determined; the target total revenue is the sum of the cooperative alliance's electricity market revenue, carbon market revenue, and green certificate market revenue; the wind-solar power plants, pumped storage power plants, and regional power grids are regarded as entities, and the entity revenue corresponding to each entity under each initial capacity configuration scheme is determined; the entity revenue is the entity's electricity market revenue, carbon market revenue, and green certificate market revenue. The sum of benefits; wind and solar power plants, pumped storage power plants, and regional power grids are paired to determine the combined revenue of each pair under each initial capacity configuration scheme; the combined revenue is the sum of the electricity market revenue, carbon market revenue, and green certificate market revenue of the combination; based on the target total revenue, the entity revenue, and the combined revenue, the marginal contribution rate of each entity is determined, and the target total revenue is allocated according to the marginal contribution rate; the marginal contribution rate is used to characterize the degree of contribution of the entity to the target total revenue of the cooperative alliance; with the allocation result of the target total revenue allocated according to the marginal contribution rate as a constraint, and with the maximum target total revenue as the objective function, multiple initial capacity configuration schemes are updated and iterated until a preset stopping condition is reached to obtain the target capacity configuration scheme, and the capacity configuration of wind, solar, and pumped storage is carried out according to the target capacity configuration scheme.
[0006] This invention randomly generates multiple initial capacity configuration schemes based on the capacity configuration parameters of wind-solar pumped storage systems, providing diverse foundations for determining subsequent target capacity configuration schemes, facilitating the discovery of better configurations, and avoiding the limitations of a single initial scheme. This invention treats wind-solar power plants, pumped storage power plants, and regional power grids as a cooperative alliance, determining the target total revenue corresponding to the alliance under each initial capacity configuration scheme. It also treats each of the wind-solar power plant, pumped storage power plant, and regional power grid as a principal entity, determining the principal entity's revenue under each initial capacity configuration scheme. Furthermore, it pairs the wind-solar power plant, pumped storage power plant, and regional power grid, determining the combined revenue for each pair under each initial capacity configuration scheme. Based on the target total revenue, principal entity revenue, and combined revenue, it determines the marginal contribution rate of each principal entity, allocating the target total revenue according to the marginal contribution rate. This multi-revenue approach to determining the marginal contribution rate and allocating revenue accurately measures the revenue contribution of each principal entity, ensuring fair and reasonable revenue distribution and stimulating the enthusiasm of all entities to participate in collaborative operation. This invention uses the allocation result of the target total revenue according to the marginal contribution rate as a constraint, and takes the maximum target total revenue as the objective function to update and iterate multiple initial capacity configuration schemes until a preset stopping condition is reached to obtain the target capacity configuration scheme. By configuring the capacity of wind-solar pumped storage based on the target capacity configuration scheme, it can pursue the optimal overall benefit of the alliance while ensuring reasonable benefits for each entity, resulting in a more adaptable and efficient target capacity configuration scheme, thus improving the operating efficiency and profitability of wind-solar pumped storage systems in multi-market environments. Compared with related technologies, this invention not only considers the joint operation mechanism of multiple entities cooperating in pumped storage units, but also the profit distribution mechanism after multi-entity participation in multi-market cooperative game, thereby further exploring the potential value of wind-solar pumped storage system operation and promoting the rational allocation and effective utilization of wind-solar pumped storage systems.
[0007] In one optional implementation, before randomly generating multiple initial capacity configuration schemes based on the capacity configuration parameters of the wind-solar pumped storage system, the method further includes: acquiring historical wind and solar power data, performing cluster analysis on the historical wind and solar power data to obtain multiple cluster groups; selecting typical days in each cluster group, and obtaining typical scenarios based on multiple typical days; the capacity configuration parameters are the capacity configuration parameters under the typical scenarios.
[0008] This invention uses cluster analysis to classify and organize complex and massive historical wind and solar power data, grouping wind and solar power data with similar characteristics into one category. It can uncover the inherent patterns in the data, select typical days from cluster grouping, and construct typical scenarios. This allows capacity configuration parameters to be based on typical scenarios, making the generated initial capacity configuration scheme more consistent with the common states of wind and solar power in actual operation, and improving the adaptability of multiple initial capacity configuration schemes.
[0009] In one optional implementation, the wind and solar power plant, pumped storage power plant, and regional power grid are considered as a cooperative alliance. The target total revenue of the cooperative alliance under each initial capacity configuration scheme is determined. This includes: constructing a joint operation model for each initial capacity configuration scheme using the wind and solar power plant, pumped storage power plant, and regional power grid as a cooperative alliance; and using the joint operation model to simulate the electricity market, carbon market, and green certificate market with the goal of maximizing revenue, thereby obtaining the target total revenue of the cooperative alliance under each initial capacity configuration scheme.
[0010] In one optional implementation, wind and solar power plants, pumped storage power plants, and regional power grids are each taken as subjects, and the subject revenue corresponding to each subject under each initial capacity configuration scheme is determined. This includes: taking wind and solar power plants, pumped storage power plants, and regional power grids as subjects, constructing subject operation models corresponding to each subject under each initial capacity configuration scheme; and using the subject operation models to simulate the electricity market, carbon market, and green certificate market with the goal of minimizing operating costs, to obtain the subject revenue corresponding to each subject under each initial capacity configuration scheme.
[0011] In one optional implementation, wind and solar power plants, pumped storage power plants, and regional power grids are combined in pairs to determine the combined revenue of each combination under each initial capacity configuration scheme. This includes: combining wind and solar power plants, pumped storage power plants, and regional power grids in pairs to obtain multiple combinations, constructing a combined operation model for each combination under each initial capacity configuration scheme; and using the combined operation model to simulate the electricity market, carbon market, and green certificate market with the goal of minimizing operating costs, to obtain the combined revenue of each combination under each initial capacity configuration scheme.
[0012] In one optional implementation, the marginal contribution rate of each entity is determined based on the target total revenue, entity revenue, and combined revenue, including: determining the weight of each set in which each entity participates based on the number of entities in the multiple sets in which each entity participates and the total number of entities in the multiple sets in which each entity participates; determining the revenue increment of each set in which each entity participates based on the target total revenue, entity revenue, and combined revenue; obtaining multiple product results by multiplying the revenue increment of each set in which each entity participates by the corresponding weight; and summing the multiple product results to obtain the marginal contribution rate of each entity.
[0013] Secondly, the present invention provides a capacity configuration device for wind-solar pumped-storage energy systems, comprising: an initial capacity determination module, used to randomly generate multiple initial capacity configuration schemes based on the capacity configuration parameters of the wind-solar pumped-storage system; the wind-solar pumped-storage system is a system in which wind-solar power stations, pumped-storage power stations, and regional power grids operate in coordination; a total revenue determination module, used to determine the target total revenue corresponding to the cooperative alliance under each initial capacity configuration scheme, taking the wind-solar power station, pumped-storage power station, and regional power grid as a cooperative alliance; the target total revenue is the sum of the cooperative alliance's electricity market revenue, carbon market revenue, and green certificate market revenue; and a principal revenue determination module, used to determine the principal revenue corresponding to each principal under each initial capacity configuration scheme, taking the wind-solar power station, pumped-storage power station, and regional power grid as principals; the principal revenue is the principal's electricity market revenue, carbon market revenue, and green certificate market revenue. The system comprises the following modules: a total revenue determination module, a combined revenue determination module, and a capacity allocation module. The combined revenue is the sum of the electricity market revenue, carbon market revenue, and green certificate market revenue of each combination. A contribution rate determination module is used to determine the marginal contribution rate of each entity based on the target total revenue, entity revenue, and combined revenue, and to allocate the target total revenue according to the marginal contribution rate. The marginal contribution rate characterizes the degree to which an entity contributes to the target total revenue of the cooperative alliance. A capacity allocation module is used to update and iterate multiple initial capacity allocation schemes with the allocation result based on the marginal contribution rate as a constraint and the maximum target total revenue as the objective function, until a preset stopping condition is met, to obtain the target capacity allocation scheme. The wind, solar, and pumped storage capacity is then allocated according to the target capacity allocation scheme.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0024] With the advancement of energy transition, large-scale grid connection of new energy sources (wind and solar power) has become a trend. However, wind and solar power generation is characterized by intermittency and volatility, posing a severe challenge to the stable operation of the power system. Pumped storage, as a technologically mature and economically feasible energy storage method, possesses the ability to respond quickly and regulate large capacity. Therefore, the coordinated development of pumped storage and new energy sources (wind and solar power) has become a key path for building a new type of power system.
[0025] In the process of coordinated development of pumped storage, wind power, and solar power, it is necessary to configure the capacity of pumped storage, wind power, and solar power to enable better collaboration between them. Related technologies only consider the optimized configuration of a single type of pumped storage unit, only consider pumped storage power stations or wind and solar bases as single stakeholders, without considering the joint operation and profit distribution between the two and the regional power grid, and only consider the configuration scheme of pumped storage power stations or wind and solar bases participating in a single electricity market transaction, without considering the coordination of multiple markets such as electricity, carbon, and green certificates.
[0026] This invention provides a capacity configuration method for wind, solar, and pumped-storage hydropower, which achieves a more realistic target capacity configuration scheme by engaging in multi-market competition among different entities.
[0027] According to an embodiment of the present invention, a capacity configuration method for wind-solar pumped-storage energy is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.
[0028] This embodiment provides a capacity configuration method for wind-solar pumped-storage energy, which can be used with computer equipment. Figure 1 This is a flowchart of a capacity configuration method for wind-solar pumped-storage hydroelectric power according to an embodiment of the present invention, such as... Figure 1 As shown, the process includes the following steps:
[0029] Step S101: Based on the capacity configuration parameters of the wind-solar pumped storage system, randomly generate multiple initial capacity configuration schemes; the wind-solar pumped storage system is a system that coordinates the operation of wind-solar power stations, pumped storage power stations, and regional power grids.
[0030] Among them, the wind-solar pumped storage system is a system composed of wind and solar power stations, pumped storage power stations and regional power grids operating in coordination; the capacity configuration parameters are parameters used to determine the capacity configuration of each component (wind and solar power station, pumped storage power station, etc.) in the wind-solar pumped storage system. For example, the capacity configuration parameters include multiple sets of wind power and photovoltaic installed capacity and the number of constant speed and variable speed pumped storage units, etc.
[0031] In some optional implementations, the capacity configuration parameters of the wind-solar pumped storage system are input into a random number algorithm to randomly generate multiple initial capacity configuration schemes. The random number algorithm includes uniform distribution random, normal distribution random, etc.
[0032] In some optional implementations, before randomly generating multiple initial capacity configuration schemes based on the capacity configuration parameters of the wind-solar pumped storage system, the capacity configuration method for wind-solar pumped storage further includes: acquiring historical wind and solar power data, performing cluster analysis on the historical wind and solar power data to obtain multiple cluster groups; selecting typical days in each cluster group, and obtaining typical scenarios based on multiple typical days; the capacity configuration parameters are the capacity configuration parameters under the typical scenarios.
[0033] Among them, K-means clustering was used to perform cluster analysis on historical wind and solar power data, resulting in multiple cluster groups.
[0034] In some optional implementations, selecting a typical day in each cluster group includes: calculating the Euclidean distance between the data of each date in each cluster group and the group feature data, and selecting the date corresponding to the data with the smallest Euclidean distance as the typical day.
[0035] Step S102: The wind and solar power plants, pumped storage power plants, and regional power grids are considered as a cooperative alliance. The target total revenue of the cooperative alliance under each initial capacity configuration scheme is determined. The target total revenue is the sum of the cooperative alliance's electricity market revenue, carbon market revenue, and green certificate market revenue.
[0036] In some optional implementations, the wind and solar power plants, pumped storage power plants, and regional power grids are considered as a cooperative alliance. The target total revenue of the cooperative alliance under each initial capacity configuration scheme is determined. This includes: constructing a joint operation model for each initial capacity configuration scheme using the wind and solar power plants, pumped storage power plants, and regional power grids as a cooperative alliance; and using the joint operation model to simulate the electricity market, carbon market, and green certificate market with the goal of maximizing revenue, thereby obtaining the target total revenue of the cooperative alliance under each initial capacity configuration scheme.
[0037] Specifically, the capacity configuration parameters in each initial capacity configuration scheme are configured into the joint operation model. With the goal of maximizing revenue, the joint operation model is used to simulate the trading behavior of wind and solar power plants, pumped storage power plants, and regional power grids in the electricity market, carbon market, and green certificate market, respectively, to obtain the revenue from the electricity market, carbon market, and green certificate market. The target total revenue is obtained by summing the revenue from the electricity market, carbon market, and green certificate market.
[0038] Step S103: Taking the wind and solar power station, pumped storage power station and regional power grid as the main body respectively, determine the main body revenue corresponding to each main body under each initial capacity configuration scheme; the main body revenue is the sum of the main body's electricity market revenue, carbon market revenue and green certificate market revenue.
[0039] In some optional implementations, wind and solar power plants, pumped storage power plants, and regional power grids are each taken as subjects, and the subject revenue corresponding to each subject under each initial capacity configuration scheme is determined. This includes: taking wind and solar power plants, pumped storage power plants, and regional power grids as subjects, constructing subject operation models corresponding to each subject under each initial capacity configuration scheme; and using the subject operation models to simulate the electricity market, carbon market, and green certificate market with the goal of minimizing operating costs, to obtain the subject revenue corresponding to each subject under each initial capacity configuration scheme.
[0040] Specifically, the capacity configuration parameters in each initial capacity configuration scheme are configured into the main operation model. With the goal of minimizing operating costs, the main operation model is used to simulate the trading behavior of each entity (wind and solar power plants, pumped storage power plants, and regional power grids) in the electricity market, carbon market, and green certificate market. The electricity market revenue, carbon market revenue, and green certificate market revenue of each entity are obtained respectively. Based on the sum of the electricity market revenue, carbon market revenue, and green certificate market revenue of each entity, the main revenue of each entity is obtained.
[0041] Step S104: Combine the wind and solar power plants, pumped storage power plants and regional power grids in pairs, and determine the combined revenue of each combination under each initial capacity configuration scheme; the combined revenue is the sum of the combined electricity market revenue, carbon market revenue and green certificate market revenue.
[0042] In some optional implementations, wind and solar power plants, pumped storage power plants, and regional power grids are combined in pairs to determine the combined revenue of each combination under each initial capacity configuration scheme. This includes: combining wind and solar power plants, pumped storage power plants, and regional power grids in pairs to obtain multiple combinations, constructing a combined operation model for each combination under each initial capacity configuration scheme; and using the combined operation model to simulate the electricity market, carbon market, and green certificate market with the goal of minimizing operating costs, to obtain the combined revenue of each combination under each initial capacity configuration scheme.
[0043] Specifically, the capacity configuration parameters in each initial capacity configuration scheme are configured into the combined operation model. With the goal of minimizing operating costs, the combined operation model is used to simulate the trading behavior of each combination (wind and solar power plants and pumped storage power plants, wind and solar power plants and regional power grids, pumped storage power plants and regional power grids) in the electricity market, carbon market, and green certificate market. The electricity market revenue, carbon market revenue, and green certificate market revenue of each combination are obtained respectively. The combined revenue of each combination is obtained by summing the electricity market revenue, carbon market revenue, and green certificate market revenue of each combination.
[0044] Step S105: Determine the marginal contribution rate of each entity based on the target total revenue, entity revenue, and combined revenue, so as to allocate the target total revenue according to the marginal contribution rate; the marginal contribution rate is used to characterize the degree of contribution of the entity to the target total revenue of the cooperative alliance.
[0045] In some alternative implementations, the marginal contribution rate of each entity is calculated based on the Shapley value method, taking into account the target total revenue, entity revenue, and portfolio revenue.
[0046] Step S106: Using the allocation result of distributing the target total revenue according to the marginal contribution rate as a constraint, and taking the maximum target total revenue as the objective function, update and iterate multiple initial capacity configuration schemes until a preset stopping condition is reached to obtain the target capacity configuration scheme, and then configure the capacity of wind-solar pumped storage according to the target capacity configuration scheme.
[0047] In some alternative implementations, the allocation result of distributing the target total revenue according to the marginal contribution rate is used as a constraint, and the maximum target total revenue is used as the objective function. Multiple initial capacity configuration schemes are input into an improved particle swarm algorithm with linearly decreasing weights, and the multiple initial capacity configuration schemes are updated and iterated until a preset stopping condition is reached to obtain the target capacity configuration scheme.
[0048] The preset stopping condition can be set according to the actual situation. For example, the preset stopping condition can reach the maximum number of iterations of the particle swarm.
[0049] The capacity configuration method for wind-solar pumped storage provided in this embodiment randomly generates multiple initial capacity configuration schemes based on the capacity configuration parameters of the wind-solar pumped storage system. This provides a diverse basis for determining the subsequent target capacity configuration scheme, facilitating the discovery of better configurations and avoiding the limitations of a single initial scheme. This embodiment treats the wind-solar power station, the pumped storage power station, and the regional power grid as a cooperative alliance. It determines the target total revenue corresponding to the cooperative alliance under each initial capacity configuration scheme. The wind-solar power station, the pumped storage power station, and the regional power grid are each treated as a principal entity, and the principal revenue corresponding to each principal entity under each initial capacity configuration scheme is determined. The wind-solar power station, the pumped storage power station, and the regional power grid are then paired, and the combined revenue corresponding to each combination under each initial capacity configuration scheme is determined. Based on the target total revenue, principal revenue, and combined revenue, the marginal contribution rate of each principal entity is determined. The target total revenue is then allocated according to the marginal contribution rate. Determining the marginal contribution rate and allocating revenue based on multiple revenues accurately measures the revenue contribution of each principal entity, ensuring fair and reasonable revenue distribution and stimulating the enthusiasm of each entity to participate in collaborative operation. This invention uses the allocation result of the target total revenue according to the marginal contribution rate as a constraint, and takes the maximum target total revenue as the objective function to update and iterate multiple initial capacity configuration schemes until a preset stopping condition is reached to obtain the target capacity configuration scheme. By configuring the capacity of wind-solar pumped storage based on the target capacity configuration scheme, it can pursue the optimal overall benefit of the alliance while ensuring reasonable benefits for each entity, resulting in a more adaptable and efficient target capacity configuration scheme, and improving the operating efficiency and profitability of wind-solar pumped storage systems in multi-market environments. Compared with related technologies, this invention not only considers the joint operation mechanism of multiple entities cooperating in pumped storage units, but also the profit distribution mechanism after multiple entities participate in multi-market cooperative game, thereby further exploring the potential value of wind-solar pumped storage system operation and promoting the rational configuration and effective utilization of wind-solar pumped storage systems.
[0050] This embodiment provides a capacity configuration method for wind-solar pumped-storage energy, which can be used with computer equipment. Figure 2 This is a flowchart of another capacity configuration method for wind-solar pumped-storage hydropower according to an embodiment of the present invention, such as... Figure 2 As shown, the process includes the following steps:
[0051] Step S201: Based on the capacity configuration parameters of the wind-solar pumped storage system, multiple initial capacity configuration schemes are randomly generated; the wind-solar pumped storage system is a system that coordinates the operation of wind-solar power plants, pumped storage power plants, and the regional power grid. For details, please refer to... Figure 1 Step S101 of the illustrated embodiment will not be described again here.
[0052] Step S202 involves forming a cooperative alliance comprised of the wind and solar power plants, pumped storage power plants, and the regional power grid. The target total revenue for this alliance is determined under each initial capacity configuration scheme. The target total revenue is the sum of the alliance's electricity market revenue, carbon market revenue, and green certificate market revenue. For details, please refer to [link to details]. Figure 1 Step S102 of the illustrated embodiment will not be described again here.
[0053] Step S203 involves treating wind and solar power plants, pumped storage power plants, and the regional power grid as separate entities, and determining the corresponding revenue for each entity under each initial capacity configuration scheme. The entity's revenue is the sum of its electricity market revenue, carbon market revenue, and green certificate market revenue. For details, please refer to [link to details]. Figure 1 Step S103 of the illustrated embodiment will not be described again here.
[0054] Step S204 involves pairing the wind and solar power plants, pumped storage power plants, and regional power grids to determine the combined revenue for each pair under each initial capacity configuration scheme. The combined revenue is the sum of the combined electricity market revenue, carbon market revenue, and green certificate market revenue. For details, please refer to [link to details]. Figure 1 Step S104 of the illustrated embodiment will not be described again here.
[0055] Step S205: Determine the marginal contribution rate of each entity based on the target total revenue, entity revenue, and combined revenue, so as to allocate the target total revenue according to the marginal contribution rate; the marginal contribution rate is used to characterize the degree of contribution of the entity to the target total revenue of the cooperative alliance.
[0056] Specifically, step S205 includes:
[0057] Step S2051: Determine the weight of each set in which each subject participates based on the number of subjects in the multiple sets in which each subject participates and the total number of subjects in the multiple sets in which each subject participates.
[0058] The three main entities in this embodiment of the invention are a wind and solar power station, a pumped storage power station, and a regional power grid, which can result in 7 sets: set 1: wind and solar power station; set 2: pumped storage power station; set 3: regional power grid; set 4: wind and solar power station and pumped storage power station; set 5: wind and solar power station and regional power grid; set 6: pumped storage power station and regional power grid; set 7: wind and solar power station, pumped storage power station, and regional power grid.
[0059] For example, the formula for determining the weight of each set in which each subject participates is:
[0060]
[0061] Where ω is the weight of each set in which each subject participates, S is any set that does not contain subject i, |S| is the number of subjects in set S, n is the total number of subjects, and |S|! is the factorial operation on the number of subjects in set S.
[0062] Step S2052: Based on the target total return, the entity's return, and the portfolio return, determine the return increment for each set in which each entity participates.
[0063] The formula for the incremental revenue of each set in which each entity participates is:
[0064] Δv=v(S∪{j})-v(S)
[0065] Where Δv is the incremental revenue of each set in which each subject participates, {j} is a set containing only subject j, v(S∪{j}) is the revenue of any set S that does not contain subject j when cooperating with {j}, and v(S) is the revenue of any set that does not contain subject j when subjects within the set cooperate.
[0066] Step S2053: Based on the product of the incremental revenue of each set in which each subject participates and the corresponding weight, multiple product results are obtained.
[0067] Step S2054: Summate the multiple product results to obtain the marginal contribution rate of each subject.
[0068] For example, the formula for determining the marginal contribution rate of each entity is:
[0069]
[0070] in, Let $\mathbf{j}$ be the marginal contribution rate of subject $j$, $N$ be the set of all cooperating subjects, $N\{j}$ be the difference operation of the sets, that is, the set of subjects remaining after removing $i$ from $N$, $S$ be any set that does not contain subject $j$, $|S|$ be the number of subjects in set $S$, $n$ be the total number of subjects, $|S|!$ be the factorial operation of the number of subjects in set $S$, ${j}$ be the set that only contains subject $j$, $v(S∪{i})$ be the benefit when any set $S$ that does not contain subject $j$ cooperates with ${j}$, and $v(S)$ be the benefit when subjects within any set $S$ that does not contain subject $j$ cooperate.
[0071] Step S206: Using the allocation result of distributing the target total revenue according to the marginal contribution rate as a constraint, and the maximum target total revenue as the objective function, update and iterate multiple initial capacity configuration schemes until a preset stopping condition is reached to obtain the target capacity configuration scheme. The wind-solar-pumped-storage capacity is then configured according to this target capacity configuration scheme. For details, please refer to [link to details]. Figure 1 Step S106 of the illustrated embodiment will not be described again here.
[0072] This embodiment provides a capacity configuration method for wind-solar pumped-storage energy, which can be used with computer equipment. Figure 3 This is a flowchart of another capacity configuration method for wind-solar pumped-storage hydropower according to an embodiment of the present invention, as shown below. Figure 3 As shown, the process includes the following steps:
[0073] Initialize the optimization parameters of the joint operation system (i.e., the wind-solar-pumped storage system) and determine the typical day. The initial typical day is t. d =1; On a typical day, a cooperative alliance is formed based on wind and solar power plants, pumped storage power plants, and regional power grids. The alliance undergoes joint operation simulations in the power market, carbon market, and green certificate market to obtain the target total revenue, entity revenue, and combined revenue. It is determined whether the calculations for each typical day are complete. If not, the market joint operation simulation is performed for the next typical day until the calculations for each typical day are completed. If the calculations for each typical day are completed, the cooperative revenue (target total revenue) of the wind-solar-constant / variable speed pumped storage-regional alliance is output. The independent operating revenue of each entity and the cooperative operating revenue of each sub-alliance (combination) under multiple markets are calculated.
