Description

Technical Field

[0001] The present application relates to the technical field of power market construction, and in particular to a method and system for secondary settlement of user-side electricity prices in a unified spot market. Background Art

[0002] Currently, electricity prices for users in different power grid regions are generally determined by the supply and demand situation within their respective regions. In the context of regional power market collaboration, due to regional differences in energy structure, socioeconomic structure, and industrial characteristics, a unified clearing price would disrupt the existing user-side electricity price structure across different regions, hindering the development of a coordinated regional spot market. Furthermore, power users in different regions have varying tolerances for electricity price fluctuations. A unified clearing price mechanism could inhibit production for some industrial and commercial users or encourage them to overuse electricity, hindering the healthy and stable development of social enterprises. Summary of the Invention

[0003] In order to at least overcome the problem of unreasonable user-side electricity price settlement in regional spot markets in related technologies to a certain extent, the present application provides a method and system for secondary settlement of user-side electricity prices in a unified spot market.

[0004] The scheme of this application is as follows:

[0005] According to a first aspect of an embodiment of the present application, a method for secondary settlement of user-side electricity prices in a unified spot market is provided, comprising:

[0006] Carry out the first settlement of user-side electricity prices within the region;

[0007] Determine the monthly average electricity price and the allowable fluctuation range of the average price for different types of users in the region;

[0008] Based on the monthly average electricity price, if the electricity price of a user during the first settlement exceeds the allowable fluctuation range of the average price, the user will be included in the second set of users to be settled in the entire region;

[0009] Divide the users in the second set of users to be settled into low-price users and high-price users; the low-price users are users whose electricity prices during the first settlement are lower than the allowable range for downward fluctuation, and the high-price users are users whose electricity prices during the first settlement are higher than the allowable range for upward fluctuation;

[0010] A second settlement is performed on the users in the second set of users to be settled according to the portion of the electricity price of the low-price users that is lower than the allowable range of downward floating during the first settlement and the portion of the electricity price of the high-price users that is higher than the allowable range of upward floating during the first settlement.

[0011] Preferably, the second settlement includes:

[0012] Recover the portion of electricity prices that are lower than the allowable range of downward fluctuation from all low-price users during the first settlement;

[0013] The recovered electricity price will be shared among high-price users.

[0014] Preferably, the recovered electricity price is shared among high-price users, including:

[0015] Calculate the sum of the portion of the electricity prices of all high-priced users that exceeds the allowable range of floating at the time of the first settlement, and determine the proportion of each high-priced user;

[0016] The recovered electricity price will be shared among high-priced users based on the proportion of each high-priced user.

[0017] Preferably, the method further comprises:

[0018] Users in the region are classified according to their electricity consumption.

[0019] Preferably, the method further comprises:

[0020] Categorize users within a region based on industry type.

[0021] Preferably, the method further comprises:

[0022] Categorize users within a region based on their geographic location.

[0023] Preferably, the monthly average price of electric energy is determined based on the weighted average price of monthly medium- and long-term contracts and spot transactions when the spot market is not developed.

[0024] Preferably, the floating range of the average price is determined according to the electricity price tolerance of different categories of users.

[0025] Preferably, the first settlement of user-side electricity prices within the region includes:

[0026] The first settlement of user-side electricity prices is made through the weighted average price of node electricity prices on the power generation side within the region.

[0027] According to a second aspect of an embodiment of the present application, a user-side electricity price secondary settlement system in a unified spot market is provided, including:

[0028] processor and memory;

[0029] The processor and the memory are connected via a communication bus:

[0030] The processor is configured to call and execute the program stored in the memory;

[0031] The memory is used to store a program, and the program is at least used to execute a secondary settlement method for user-side electricity prices in a unified spot market as described in any one of the above items.

[0032] The technical solution provided by this application may have the following beneficial effects:

[0033] The secondary settlement method of user-side electricity prices in the regional spot market in the present application includes: conducting a first settlement of user-side electricity prices within the region; determining the monthly average electricity price and the allowable floating range of the average price corresponding to different types of users in the region; based on the monthly average electricity price, if the electricity price of a user exceeds the allowable floating range of the average price at the time of the first settlement, the user will be included in the second set of users to be settled in the entire region; the users in the second set of users to be settled are divided into low-price users and high-price users; low-price users are users whose electricity prices are lower than the allowable floating range at the time of the first settlement, and high-price users are users whose electricity prices are higher than the allowable floating range at the time of the first settlement; a second settlement is conducted for the users in the second set of users to be settled based on the portion of the electricity prices of the low-price users that is lower than the allowable floating range at the time of the first settlement and the portion of the electricity prices of the high-price users that is higher than the allowable floating range at the time of the first settlement.

[0034] In this technical solution, a first electricity price settlement is first performed for users within the region. Then, based on whether the user's first electricity price settlement exceeded the permissible fluctuation range of the region's monthly average electricity price, a determination is made as to whether the user needs a second electricity price settlement. If the user's first electricity price settlement exceeds the permissible fluctuation range of the region's monthly average electricity price, the user with the lower electricity price must compensate the user with the higher electricity price. This compensation process is referred to as the second electricity price settlement. The two electricity price settlements in this technical solution, the first of which is performed within the region and the second is performed across the entire region, fully consider the differences between regions in terms of energy structure, socioeconomics, and industrial characteristics, and incorporate the permissible fluctuation range of the monthly average electricity price for various types of users in different regions. This comprehensive, systematic, and objective approach is adopted. The secondary settlement mechanism can effectively leverage the coordinated development of regional power markets, ensuring that all types of electricity users can fairly enjoy services and bear corresponding costs, thereby enhancing the overall efficiency and sustainability of regional spot market development.

[0041] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0042] Example 1

[0043] Figure 1 This is a flow chart of a method for secondary settlement of user-side electricity prices in a unified spot market provided by an embodiment of the present application, with reference to Figure 1 A method for secondary settlement of user-side electricity prices in a unified spot market, comprising:

[0044] S11: Carry out the first settlement of user-side electricity prices within the region;

[0045] It should be noted that the region in this application refers to the prefecture-level administrative region, and multiple regions can form a region.

[0046] It should be noted that the first settlement of user-side electricity prices within the region includes:

[0047] The first settlement of user-side electricity prices is made through the weighted average price of electricity prices at the power generation side nodes within the region.

[0048] In the regional spot market environment, for any type of user, the spot market settlement price adopts the weighted average price of the node electricity price on the power generation side, and the user-side electricity price is settled for the first time through the unified settlement point price in the region.

[0049] S12: Determine the monthly average electricity price and the allowable floating range of the average price corresponding to different types of users in the region;

[0050] It should be noted that there are many types of electricity users. In this embodiment, the corresponding monthly average electricity price and the allowable floating range of the average price need to be determined according to different types of users.

[0051] In actual practice, users can be classified according to industry type, electricity consumption or geographical location, and the specific classification results can be formulated in combination with the characteristics of the region.

[0052] Each region classifies different users according to their own user type characteristics and formulates the monthly average electricity price and the allowable floating range of the average price.

[0053] For example, the monthly average electricity price and the allowable floating range of the average price corresponding to different types of users in the region are shown in the following table:

[0054]

[0055] It should be noted that the monthly average electricity price is determined based on the weighted average price of monthly medium- and long-term contracts and spot transactions when the spot market is not developed.

[0056] It should be noted that the floating range of the average price is determined according to the electricity price affordability of different categories of users.

[0057] S13: Based on the monthly average electricity price, if the electricity price of a user during the first settlement exceeds the allowable fluctuation range of the average price, the user will be included in the second set of users to be settled in the entire region;

[0058] In this embodiment, users whose electricity prices during the first settlement are outside the allowable floating range of the average price are included in the second set of users to be settled in the entire region, that is, users in the region who are outside the allowable floating range of the average price participate in the second settlement.

[0059] S14: Divide the users in the second set of users to be settled into low-price users and high-price users; low-price users are users whose electricity prices during the first settlement are lower than the allowable range for downward fluctuation, and high-price users are users whose electricity prices during the first settlement are higher than the allowable range for upward fluctuation;

[0060] Assume that the actual monthly average electricity price p(A-1) of A-1 type users in region A is lower than the allowable range for downward fluctuation, the actual monthly average electricity price p(B-1) of B-1 type users in region B is higher than the allowable range for upward fluctuation, the actual monthly average electricity price p(C-2) of C-2 type users in region C is higher than the allowable range for upward fluctuation, and the actual monthly average electricity prices of other users are all within the allowable range.

[0061] Then, the A-1 type users in area A are identified as low-price users, the B-1 type users in area B and the C-2 type users in area C are identified as high-price users, and these three types of users are included in the second set of users to be settled in the entire region.

[0062] S15: Perform a second settlement for the users in the second set of users to be settled based on the portion of the electricity price of the low-price users that is lower than the allowable range of downward floating during the first settlement and the portion of the electricity price of the high-price users that is higher than the allowable range of upward floating during the first settlement.

[0063] Specifically, refer to Figure 2 , the second settlement includes:

[0064] S151: Recover the portion of the electricity price that is lower than the allowable range of the downward price from all low-price users during the first settlement;

[0065] The recovered electricity price will be shared among high-price users.

[0066] Furthermore, the recovered electricity price will be shared among high-price users, including:

[0067] S152: Calculate the sum of the portion of the electricity prices of all high-priced users that exceeds the allowable range of the floating increase during the first settlement, and determine the proportion of each high-priced user;

[0068] S153: The recovered electricity price is distributed among the high-price users according to the proportion of each high-price user.

[0069] For example:

[0070] As shown above, the A-1 type users in region A are determined as low-price users, and the B-1 type users in region B and the C-2 type users in region C are determined as high-price users.

[0071] The portion of the electricity price of type A-1 users that is lower than the allowable downward range during the first settlement will be recovered.

[0072] Assume that the sum of the portion of the electricity prices of type B-1 users in region B and type C-2 users in region C that is higher than the allowable floating range is 10, the proportion of type B-1 users in region B is 3, and the proportion of type C-2 users in region C is 7. Then the recovered electricity price will be allocated to type B-1 users in region B and type C-2 users in region C at a ratio of 3:7.

[0073] In this technical solution, the first electricity price settlement is first carried out for users within the region, and then it is determined whether the user needs to conduct a second electricity price settlement based on whether the user exceeds the allowable floating range of the monthly average electricity price in the region when conducting the first electricity price settlement. If the user exceeds the allowable floating range of the monthly average electricity price in the corresponding region when conducting the first electricity price settlement, the user with a lower electricity price needs to compensate the user with a higher electricity price. This compensation process is the second electricity price settlement. The two electricity price settlements in this technical solution are carried out for the first time within the region and the second time in the entire region. It fully considers the differences in energy structure, social economy, industrial characteristics, etc. between different regions, and combines the allowable floating range of the monthly average electricity price of various users in different regions. It is comprehensive, systematic and objective. The secondary settlement mechanism can effectively play the role of coordinated development of regional power markets, ensure that various types of electricity users can enjoy services and bear corresponding costs fairly, and enhance the overall benefits and sustainability of regional spot market development.
