Description

Technical Field

[0001] The present invention relates to the technical field of power systems, and in particular to a method, system, device and medium for distributing profits in a power market. Background Art

[0002] With the transformation of energy structure and the continuous development of the power market, user-side distributed photovoltaic storage systems have gradually become an important part of the power market. By combining photovoltaic power generation with energy storage technology, photovoltaic storage systems can not only reduce users' electricity costs, but also obtain additional benefits by participating in the power market. However, the operation characteristics of distributed photovoltaic storage systems are intermittent and volatile, which brings new challenges to their profit distribution in the power market. The traditional profit distribution method of the power market mainly relies on the matching of power generation and power consumption, while the output of distributed photovoltaic storage systems is uncertain and easily affected by multiple factors such as weather conditions, photovoltaic storage configuration ratio, user demand, etc., which leads to fluctuations in performance capabilities.

[0003] The existing profit distribution method of the electricity market is mainly based on the real-time electricity price mechanism and contract price in the electricity market. User-side photovoltaic storage systems usually obtain revenue in two ways: the first is to participate in the real-time electricity trading market and sell electricity to the power grid during peak electricity demand; the second is to sign a long-term contract with the power company and sell a fixed amount of electricity at the price agreed in the contract. According to this model, the user's revenue is closely related to his actual power generation, the use of the energy storage system and the market electricity price. The market electricity price usually fluctuates greatly. Users can respond to real-time changes in electricity prices and adjust the discharge timing of their photovoltaic power generation and energy storage, thereby obtaining higher market returns. At present, the profit distribution of distributed photovoltaic storage systems in the electricity market mainly faces the following challenges:

[0004] First, the impact of the performance deficit on operating costs and grid pressure in the event of default is not fully considered. When calculating the response unit price, the significant increase in overall operating costs and the potential pressure on grid stability and carrying capacity caused by the performance deficit in the event of default are not fully evaluated, which cannot motivate users to optimize performance. This may lead to higher operating risks and pressure on the grid when part of the system defaults during actual operation, affecting the stability of the entire power system. The corresponding costs are not reasonably reflected in the unit price setting, which weakens the system's response ability and economy.

[0005] Second, the three-dimensional profit distribution of basic distribution, income deduction and profit redistribution is not considered. Usually, the income is directly distributed according to the user's contribution or response volume, lacking consideration of default risk and performance, resulting in insufficient fairness and weak incentives, and failing to effectively reward compliant users and punish defaulting users. In addition, this method has poor flexibility and is difficult to cope with market fluctuations and performance changes, which can easily increase systemic risks and reduce overall stability.

[0006] For example, Chinese patent CN112465248B discloses a virtual power plant optimization operation and revenue distribution method and system considering carbon trading. This method uses the Shapley value calculation method to determine the distribution of power market revenue based on the bidding volume in the day-ahead market. The defect of not fully considering the impact of the performance deficit on operating costs and grid pressure in the event of default, and not fully assessing the significant increase in overall operating costs and potential pressure on grid stability and carrying capacity caused by the performance deficit in the event of default, has led to higher operating risks and pressure on the grid, affecting the stability of the entire power system.

[0007] Therefore, how to provide a method, system, equipment and medium for distributing profits in the electricity market is a problem that needs to be solved urgently. Summary of the invention

[0008] The embodiments of the present invention provide a method, system, device and medium for distributing profits in an electricity market to solve the above-mentioned technical problems existing in the prior art.

[0009] In order to have a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended to be a general review, nor is it intended to identify key / important components or to delineate the scope of protection of these embodiments. Its only purpose is to present some concepts in a simple form as a preface to the detailed description that follows.

[0010] According to a first aspect of an embodiment of the present invention, a method for distributing profits in an electricity market is provided.

[0011] In one embodiment, the electricity market profit distribution method includes:

[0012] Based on the performance behavior and default pressure of the user-side distributed photovoltaic storage system in the historical profit distribution cycle, an expected performance model and a reserved cost ratio model are constructed to predict the expected performance of the user-side distributed photovoltaic storage system and the reserved cost ratio of the aggregator in the current profit distribution cycle.

[0014] In one embodiment, based on the performance behavior and default pressure of the user-side distributed photovoltaic storage system in the historical profit distribution cycle, the expected performance model and the reserved cost ratio model are constructed to predict the expected performance of the user-side distributed photovoltaic storage system and the reserved cost ratio of the aggregator in the current profit distribution cycle, and the response unit price of the user-side distributed photovoltaic storage system participating in the power market is formulated in combination with the expected performance and the reserved cost ratio of the aggregator, including:

[0015] Set the profit distribution cycle of the user-side distributed photovoltaic storage system participating in the power market, obtain the performance behavior and default pressure of all user-side distributed photovoltaic storage systems in the historical profit distribution cycle, extract feature vectors, assign feature vector weights, build an expected performance model, and use the expected performance model to calculate the expected performance of each user-side distributed photovoltaic storage system in the current profit distribution cycle;

[0016] Obtain the performance deficit of the distributed photovoltaic storage system on the user side in the event of default and the operating costs and grid bearing pressure caused by the performance deficit, and calculate the proportion of the aggregator's reserved costs in the current profit distribution cycle;

[0017] Based on the principle of fulfillment priority, different fulfillment weights are assigned to user-side distributed photovoltaic storage systems with different fulfillment degrees. Combined with the expected fulfillment degree in the current profit distribution cycle and the proportion of reserved costs by the aggregator, the response unit price of each user-side distributed photovoltaic storage system in the current profit distribution cycle is calculated.

[0018] In one embodiment, the formula for calculating the expected performance of each user-side distributed photovoltaic storage system in the current profit distribution cycle using the expected performance model is:

[0019]

[0020] In the formula, R m (t) is the expected performance of the mth user-side distributed photovoltaic storage system in the tth profit distribution period; f(·) is the construction function of the expected performance of the user-side distributed photovoltaic storage system; ReLU(·) is the activation function; is the i-th eigenvector of the m-th user-side distributed photovoltaic storage system in the t-th profit distribution period.

[0024] In one embodiment, the formula for calculating the response unit price of each user-side distributed photovoltaic storage system in the current profit distribution period is:

[0025] Pm(t)=P0(1+θRm(t)-ηH(t))

[0026] Where P m (t) is the response unit price of the mth user-side distributed photovoltaic storage system in the tth profit distribution cycle; P0 is the benchmark response unit price; θ is the expected performance weight of the user-side distributed photovoltaic storage system; η is the weight of the aggregator's reserved cost ratio; R m (t) is the expected performance of the mth user-side distributed photovoltaic storage system in the tth profit distribution period; H(t) is the proportion of the aggregator's reserved cost in the tth profit distribution period.

[0027] In one embodiment, the calculation of the response income of the user-side distributed photovoltaic storage system in the current profit distribution cycle is based on the principle of minimizing the performance deficit, and a three-layer mechanism of basic distribution, income deduction and profit redistribution is constructed to dynamically respond to the user's performance, give priority to covering the default cost, and distribute the remaining profit to compliant users, including:

[0028] Obtain the response amount of the user-side distributed photovoltaic storage system in the current profit distribution cycle, and calculate the response income of each user-side distributed photovoltaic storage system in the current profit distribution cycle by combining the calculated expected performance of the user-side distributed photovoltaic storage system in the current profit distribution cycle and the proportion of the aggregator's reserved costs;

[0029] Based on the increase in operating costs and system bearing pressure caused by the performance deficit, the accumulated fees paid by the user-side distributed photovoltaic storage system to the power grid are calculated, and the aggregator reserved cost is obtained. The aggregator reserved cost and the accumulated cost are compared. If the aggregator reserved cost is greater than or equal to the accumulated cost, it is determined that the aggregator reserved cost can cover the accumulated cost. If the aggregator reserved cost is less than the accumulated cost, it cannot cover the accumulated cost.

[0030] When the aggregator's reserved costs cannot cover the accumulated costs, based on the principle of minimizing the performance deficit, the income of the defaulting user-side distributed photovoltaic storage system will be deducted to offset the costs incurred by the default;

[0036] Calculate the difference between the aggregator's retained costs and the accumulated costs caused by the performance deficit based on the aggregator's retained costs and the accumulated costs;

[0037] By offsetting the difference in response income, the accumulated costs caused by the performance deficit are covered, the performance deficit is minimized, and the post-deduction response income of each user-side distributed photovoltaic storage system is recalculated.

[0038] In one embodiment, the formula for recalculating the post-deduction response income of each user-side distributed photovoltaic storage system is:

[0039] W m ′(t)=W m (t)-min(W m (t),E m (t))

[0040] Where W m ′(t) is the response income after deduction of the mth user-side distributed photovoltaic storage system in the tth profit distribution period; W m(t) is the response income of the mth user-side distributed photovoltaic storage system in the tth profit distribution cycle; E m (t) is the difference between the aggregator’s reserved cost and the accumulated fee of the mth user-side distributed solar storage system in the tth profit distribution period.

[0041] In one embodiment, when the aggregator reserved cost can cover the accumulated fee, screening all user-side distributed photovoltaic storage systems that meet the requirements of compliant users and performing profit redistribution of the aggregator's remaining cost includes:

[0042] Acquire all user-side distributed photovoltaic storage systems that have not defaulted or whose performance deficit is within the preset acceptable range as compliant users that can participate in profit redistribution;

[0043] Based on the expected compliance value, the remaining cost of the aggregator is distributed as profit to all compliant users, and the reward profit that each compliant user can obtain in the future profit distribution cycle is calculated.

[0044] In one embodiment, the formula for calculating the reward profit that each compliant user can obtain in the future profit distribution period is:

[0045]

[0085] In this optional embodiment, the formula for calculating the expected performance of each user-side distributed photovoltaic storage system in the current profit distribution cycle using the expected performance model is:

[0086]

The response amount of the user-side distributed photovoltaic storage system in the current profit distribution cycle can be obtained, and the response income of each user-side distributed photovoltaic storage system in the current profit distribution cycle is calculated based on the expected performance of the user-side distributed photovoltaic storage system in the current profit distribution cycle and the proportion of the aggregator's reserved costs; based on the increase in operating costs and system carrying pressure caused by the performance deficit, the user-side distributed photovoltaic storage system is calculated. The accumulated fees paid by the household-side distributed photovoltaic storage system to the power grid are obtained, and the reserved costs of the aggregator are obtained. The values ​​of the reserved costs of the aggregator are compared with the accumulated fees. If the reserved costs of the aggregator are greater than or equal to the accumulated fees, it is determined that the reserved costs of the aggregator can cover the accumulated fees.

Based on the principle of minimizing the performance deficit, it constructs a three-layer mechanism of basic distribution, income deduction and profit redistribution, dynamically responds to the user's performance, gives priority to covering the default cost, and distributes the remaining profit to compliant users.

[0110] In this optional embodiment, the response unit price formulation module 201 includes: an expected performance module (not shown in the figure), a reserved cost ratio module (not shown in the figure) and a response unit price module (not shown in the figure), wherein the expected performance module is used to set the profit distribution cycle of the user-side distributed photovoltaic storage system participating in the power market, obtain the performance behavior and default pressure of all user-side distributed photovoltaic storage systems in the historical profit distribution cycle, extract feature vectors, and assign feature vector weights, construct an expected performance model, and use the expected performance model to calculate the performance of each user-side distributed photovoltaic storage system in the historical profit distribution cycle. The expected performance degree of the current profit distribution cycle; the reserved cost ratio module is used to obtain the performance deficit of the user-side distributed photovoltaic storage system in the event of a breach of contract and the operating cost and grid bearing pressure caused by the performance deficit, and calculate the aggregator reserved cost ratio of the current profit distribution cycle; the response unit price module is used to assign different performance weights to user-side distributed photovoltaic storage systems with different performance degrees based on the performance priority principle, and calculate the response unit price of each user-side distributed photovoltaic storage system in the current profit distribution cycle in combination with the expected performance degree of the current profit distribution cycle and the aggregator reserved cost ratio.

[0112] The following is a detailed description of a transmission and distribution coordinated double-layer economic dispatch method and system constructed by the present invention in conjunction with specific embodiments and drawings.

[0113] The present invention proposes a profit distribution method for a user-side distributed photovoltaic storage system participating in the power market. The specific process is as follows: Figure 1 shown.

[0114] First, the expected compliance of the system is predicted, and based on the default risk and operating costs, a higher response unit price is set for the system with high compliance. Through the three-dimensional profit distribution method of basic income distribution, default deductions and residual profit redistribution, profits are reasonably distributed to encourage compliance, reduce defaults, and improve the profitability and stability of the power market.

[0115] Among them, the user-side distributed photovoltaic storage system refers to the distributed photovoltaic power generation system and energy storage equipment (such as lithium batteries) installed at the user end (such as homes, commercial buildings or industrial enterprises). Through integrated optimization, the photovoltaic power generation and energy storage systems can work in coordination with each other to a certain extent, thereby improving energy utilization efficiency, reducing electricity costs and achieving energy self-sufficiency.

[0116] Specifically, the present invention first designs a response profit unit price formulation method for distributed photovoltaic storage systems participating in the power market with priority on performance, and formulates the response unit price of the system participating in the power market by constructing the expected performance of the distributed photovoltaic storage system and combining the default risk and operating cost, including the following aspects: first, predicting the performance according to the geographical location, configuration ratio and other characteristics; then calculating the reserved cost ratio based on the operating pressure of the system in the event of default; finally, according to the principle of priority on performance, formulating a higher response unit price for systems with high performance, thereby improving the performance incentive of the system, ensuring the stability of the power grid and improving market efficiency.

[0117] Next, the present invention also designs a three-dimensional profit distribution method for distributed photovoltaic and energy storage systems participating in the electricity market based on minimizing the performance deficit. The three-dimensional profit distribution method can dynamically respond to the performance of users through the three-layer mechanism of basic distribution, income deduction and profit redistribution, give priority to covering the default costs, ensure that the system risk is controllable, and at the same time reward the remaining profits to compliant users, thereby achieving higher fairness and incentive effects.

[0118] Compared with traditional methods, it improves the flexibility of allocation, can effectively adapt to market changes, enhance system stability and encourage users to improve fulfillment rates.

[0119] In a further embodiment, the responsive profit unit price formulation for distributed photovoltaic storage systems participating in the electricity market with compliance priority can be presented as follows.

[0120] 1.1. Constructing the expected performance of the distributed photovoltaic storage system on the user side

[0121] In order to accurately evaluate the performance and risk of the system when participating in the electricity market. By predicting the performance, we can better understand whether each system can fulfill its commitment to the power grid on time, and then provide a basis for formulating reasonable response unit prices and profit distribution. Considering M user-side distributed photovoltaic storage systems and T profit distribution cycles, for the t-th profit distribution cycle and the m-th user-side distributed photovoltaic storage system, according to the distance between the user-side distributed photovoltaic storage system and the main grid node Optical / storage configuration ratio Historical performance average Number of breaches Performance deficit in each default scenario and the resulting increased operating costs Power grid bearing pressure Minimum value of fulfillment redundancy Redundant fluctuation range of fulfillment Etc., to form the feature vector:

[0122]

[0123] The expected performance of the distributed photovoltaic storage system on the user side is constructed based on the characteristic vector and characteristic vector weight of the distributed photovoltaic storage system on the user side, which is expressed as:

[0124]

[0125] In the formula, R m (t) is the expected performance of the mth user-side distributed photovoltaic storage system in the tth profit distribution period, f(·) is the expected performance construction function of the user-side distributed photovoltaic storage system, and the weighted sum of each eigenvalue and weight is mapped into an output result of expected performance, which is used to evaluate or predict whether the user-side distributed photovoltaic storage system can fulfill its commitment as expected in the future; ReLU(·) is the activation function.

[0126] 1.2. Calculate the reserved cost ratio

[0127] In order to reserve the cost required to deal with default risk in advance, ensure that there are sufficient funds or resources to deal with the impact of performance deficit and increased operating costs when the system fails to perform or defaults, and reduce the negative impact on the grid's carrying pressure, the aggregator's reserved cost ratio is calculated. The aggregator's reserved cost ratio is the ratio of the cost reserved to deal with possible default risks and performance deficits to the current expected operating costs. The higher the aggregator's reserved cost ratio, the more funds the aggregator needs to deal with risks, thereby reducing the impact of default on the grid and the market.

[0128] The performance deficit reflects the severity of the system default. The larger the deficit, the more costs the aggregator needs to reserve. Default will lead to an increase in system operating costs, such as additional dispatch costs or backup power costs. System default may bring additional load pressure to the power grid, especially at high loads, and aggregators need to spend more to cope with it. Therefore, based on the performance deficit in the case of default and the operating costs and grid load pressure caused by it, the system load pressure constraint is oriented to the system load pressure constraint. δ is the carrying pressure threshold, and the aggregator reserved cost ratio H(t) in the t-th profit distribution cycle is calculated as:

[0129]

[0130] In the formula, α is the weight of the increase in the performance deficit cost, β is the weight of the bearing pressure, γ is the increase cost per unit of bearing pressure, and D m (t) is the performance income of the mth user-side distributed photovoltaic storage system in the tth profit distribution period.

[0131] 1.3. Formulate the response unit price of each user-side distributed photovoltaic storage system

[0132] In order to encourage user-side distributed photovoltaic storage systems to actively participate in the electricity market, differentiated pricing is implemented based on performance capabilities. User-side distributed photovoltaic storage systems with high performance can provide electricity services more reliably, so they can obtain higher unit prices to encourage them to respond first. However, due to the higher risk of default, user-side distributed photovoltaic storage systems with low performance need to balance risks by reducing unit prices or reserving more costs. This pricing mechanism not only ensures the stability of the electricity market, but also improves the overall economic benefits and system enthusiasm.

[0133] The idea of ​​giving priority to performance is adopted to set a higher response unit price for distributed photovoltaic storage systems with high performance. At the same time, a high proportion of reserved costs means that the system needs to reserve more funds to deal with risks, so the response unit price needs to be appropriately reduced. Based on the proportion of reserved costs of the aggregator and the expected performance of the distributed photovoltaic storage system on the user side, the response unit price P of the mth user-side distributed photovoltaic storage system in the tth profit distribution cycle is formulated. m (t), expressed as:

[0134] Pm(t)=P0(1+θRm(t)-ηH(t))

[0135] Where P0 is the benchmark response unit price, θ is the expected performance weight of the distributed photovoltaic storage system on the user side, and η is the weight of the aggregator's reserved cost ratio.

[0136] In a further embodiment, a three-dimensional profit distribution method for distributed photovoltaic and storage systems participating in the electricity market based on minimizing performance deficits can be presented as follows.

[0137] 2.1 Basic Allocation

[0138] At the end of each profit distribution cycle, the user-side distributed photovoltaic storage system needs to calculate the response unit price based on steps 1.1-1.3. The response income of each user-side distributed photovoltaic storage system comprehensively considers its response unit price, the response volume of the user-side distributed photovoltaic storage system, the total profit, and the reserved cost ratio. It ensures that each system can not only obtain income according to its contribution, but also make reasonable preparations for possible default risks, achieving stable market operation and fair profit distribution.

[0139] Combined with the aggregator's reserved cost ratio H(t), the mth user-side distributed photovoltaic storage system response Q in the tth profit distribution cycle m (t), calculate the response income W of the mth user-side distributed photovoltaic storage system in the tth profit distribution period m (t), expressed as:

[0140] Wm(t)=Qm(t)Pm(t)(1-H(t))

[0141] 2.2. Determination of reserved costs

[0142] To ensure that the distributed photovoltaic storage system on the user side has the ability to cope with the risk of default, it is necessary to determine whether the reserved cost can cover the increase in operating costs caused by the performance deficit and the fees that need to be paid to the grid due to the increase in system load pressure. The accumulated fee V paid to the grid by the mth user-side distributed photovoltaic storage system due to the increase in operating costs caused by the performance deficit and the increase in system load pressure in the tth profit distribution period m (t) is expressed as:

[0143] V m (t) = K m (t)+L m (t)

[0144] In the formula, K m (t) is the operating cost of the mth user-side distributed photovoltaic storage system due to the performance deficit in the tth profit distribution period, L m (t) is the fee that the mth user-side distributed photovoltaic storage system needs to pay to the grid due to the increase in carrying pressure in the tth profit distribution cycle.

[0145] The aggregator reserves the cost H(t)Q m (t)P m (t), compare the reserved cost H(t)Q m (t)P m (t) The cumulative fees V that need to be paid to the grid due to the performance deficit and the resulting operating costs and increased system load pressure m (t), if H(t)Q m (t)P m (t)≥V m (t), it can cover the performance deficit and the operating costs caused by it, as well as the accumulated fees that need to be paid to the power grid due to the increase in system load pressure. m (t)P m (t)<V m (t), it cannot be overwritten.

[0146] 2.3. Deduction of income

[0147] When the reserved cost cannot cover the increase in operating costs caused by the performance deficit and the fees paid to the grid due to the increase in system load pressure, in order to ensure that the system can reasonably cope with the economic impact of the default, it is necessary to deduct the income of the defaulting distributed photovoltaic storage system based on the principle of minimizing the performance deficit. This income deduction mechanism is to offset the costs caused by the default and reduce further impact on the stability of the grid.

[0148] Calculate the aggregator reservation cost H(t)Q m (t)P m(t) The cumulative fees V that need to be paid to the grid due to the performance deficit and the resulting operating costs and increased system load pressure m The difference of (t) is expressed as:

[0149] E m (t) = V m (t)-H(t)Q m (t)P m (t)

[0150] By offsetting the difference in response income, the increased operating costs caused by the performance deficit and the fees paid to the grid due to the increased system load pressure are covered, the performance deficit is minimized, and the response income W of the mth user-side distributed photovoltaic storage system is recalculated. m ′(t), expressed as:

[0151] W m ′(t)=W m (t)-min(W m (t),E m (t))

[0152] Where W m ′(t) is the response income after deduction of the mth user-side distributed photovoltaic storage system in the tth profit distribution period; W m (t) is the response income of the mth user-side distributed photovoltaic storage system in the tth profit distribution cycle; E m (t) is the difference between the aggregator’s reserved cost and the accumulated fee of the mth user-side distributed solar storage system in the tth profit distribution period.

[0153] 2.4. Profit redistribution

[0154] When the reserved cost can cover the increase in operating costs caused by system default and the costs caused by grid load pressure, the remaining costs can be redistributed. Assume that there are M′ user-side distributed photovoltaic storage systems that have not defaulted or whose performance deficit is within an acceptable range. According to the expected performance degree, the remaining cost of the aggregator is distributed as profit to M′ user-side distributed photovoltaic storage systems that have not defaulted or whose performance deficit is within an acceptable range, expressed as:

[0155]

[0156] In the formula, S m (t+1) is the profit allocated to the mth user-side distributed photovoltaic storage system in the t+1th profit distribution cycle. This distribution method encourages the system to maintain a high degree of compliance while ensuring that those with low default risk in the market can obtain more profits.
