[0057] Figure 3 A schematic diagram of the structure of an inter-provincial electricity transfer device provided in an embodiment of this application is shown. Detailed Implementation

[0058] The present application will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of the present application can be combined with each other.

[0059] This embodiment provides a method for cross-provincial electricity trading, such as... Figure 1 As shown, the method includes:

[0060] Step 101: Obtain data on the transaction volume category, transaction cycle, national mandatory plan allocation ratio, transaction volume limit for each cycle, and inter-provincial tie line channel stability limit for inter-provincial transaction volume.

[0061] This application embodiment can be applied to scenarios where various types of electrical energy within a region are traded and transferred in inter-provincial medium- and long-term markets. To meet the electricity purchase demands of participating power buyers within a region at different time scales for different types of electricity, and to fully utilize the existing power resources of power generation entities, it is necessary to comprehensively consider the types of electrical energy produced by power generation entities within the region, the electricity purchase demands of each province, and the transmission capacity of inter-provincial transmission lines. In this application embodiment, the first step is to obtain data on the types of electricity traded in inter-provincial transactions, the transaction cycle, the electricity allocation ratio of the national mandatory plan, the transaction electricity limit for each cycle, and the stability limit of inter-provincial transmission lines for each cycle, in preparation for determining the transferred electricity volume.

[0062] Step 102: Based on the transaction electricity category, the transaction cycle, the electricity allocation ratio of the national mandatory plan, the transaction electricity limit for each cycle, and the inter-provincial interconnection channel stability limit data for each cycle, obtain the first electricity flow of each category of transaction electricity between different transaction cycles.

[0063] Next, based on the aforementioned electricity trading categories in the aforementioned trading cycles, and further based on the electricity allocation ratio of the aforementioned national mandatory plan, the electricity trading limits for each cycle, and the inter-provincial interconnection channel stability limits for each cycle, the first electricity flow of each category of electricity trading between different trading cycles is obtained. For example, the transaction execution volume of the first category of electricity trading in annual, monthly, and weekly transactions is obtained, as well as the transaction execution volume of the second category of electricity trading in annual, monthly, and weekly transactions. By obtaining the electricity flow of each category of electricity in each cycle, it is determined whether the flow of each type of electricity between different cycles in cross-cycle transactions is complete and smooth, in preparation for determining the value of untraded electricity that can enter other electricity markets.

[0064] Step 103: Based on the transaction electricity limit for each period and the inter-provincial interconnection channel stability limit data for each period, obtain the second electricity flow of various transaction electricity amounts within the same transaction period.

[0065] Next, based on the transaction volume limits and inter-provincial interconnection line channel stability limits for each of the above cycles, the second volume flow of various transaction volumes within the same transaction cycle is obtained. For example, during annual transactions, the volume of first-class and second-class volumes flowing into third-class volumes is obtained, and during monthly transactions, the volume of first-class volumes flowing into second-class volumes is obtained. By obtaining the volume flow of various types of volumes within the same transaction cycle, it is determined whether the flow between different types of volumes in cross-category transactions is clear and whether the direction of flow is clear, thus preparing for the next step of determining the value of untraded volumes that can enter other volume markets.

[0066] Step 104: Determine the value of untraded electricity that can enter other electricity markets based on the first electricity flow and the second electricity flow.

[0067] Next, based on the aforementioned first and second electricity flows, the value of untraded electricity that can enter other electricity markets will be determined, and the untraded electricity after the conclusion of inter-provincial medium- and long-term transactions will be guided into other electricity markets.

[0068] By applying the technical solution of this embodiment, the following data are obtained for inter-provincial electricity trading: trading volume category, trading cycle, national mandatory plan electricity allocation ratio, trading volume limit for each cycle, and inter-provincial tie-line channel stability limit for each cycle. Based on these data, the first electricity flow of each category of trading volume between different trading cycles is obtained. Based on the trading volume limit for each cycle and the inter-provincial tie-line channel stability limit for each cycle, the second electricity flow of various trading volumes within the same trading cycle is obtained. The untraded electricity volume value that can enter other electricity markets is determined based on the first and second electricity flows. By determining the closed-loop flow of various types of electricity in inter-cycle and inter-category trading, the untraded electricity volume is connected to the inter-provincial medium- and long-term electricity market and other electricity markets. This achieves full flow of various types of electricity within the region in the inter-provincial medium- and long-term market and effectively connects other electricity markets, improving the efficiency of electricity market optimization and allocation.

[0069] Furthermore, as a refinement and extension of the specific implementation of the above embodiments, to fully illustrate the specific implementation process of this embodiment, another method for cross-provincial electricity trading is provided. The electricity trading categories include nationally mandated plan guaranteed quantity and price electricity (E1), nationally mandated plan guaranteed quantity and bidding electricity (E2), green electricity (E3), and surplus / deficit mutual assistance electricity (E4). The trading cycle includes annual, monthly, weekly, and multi-day periods. The first electricity trading includes determining the E3 category of decomposed electricity, and the second electricity trading includes determining the E4 category of annual trading electricity. The untraded electricity value also includes green electricity value. Figure 2 As shown, the method includes:

[0070] Step 201: Obtain data on the transaction volume category, transaction cycle, national mandatory plan allocation ratio, transaction volume limit for each cycle, and inter-provincial interconnection channel stability limit for inter-provincial transaction volume.

The above-mentioned transaction cycles include: annual, monthly, weekly, and multi-day.

[0072] Step 202: Determine the transaction execution volume, transaction breakdown volume, and transaction breakdown curve for E1, E2, E3, and E4 electricity categories in annual, monthly, weekly, and multi-day periods. The first electricity flow includes the transaction execution volume, transaction breakdown volume, and transaction breakdown curve.

[0073] Next, the transaction execution volume, transaction breakdown volume, and transaction breakdown curve for E1, E2, E3, and E4 electricity categories are determined on an annual, monthly, weekly, and multi-day basis. The first electricity flow includes the transaction execution volume, transaction breakdown volume, and transaction breakdown curve. These figures determine the flow of each type of electricity category across different periods in cross-cycle transactions and allow for adjustments to mitigate the performance risks of market participants. For example, the cross-provincial annual, monthly, and weekly transaction execution volume for E1 electricity categories can be determined. The system determines the executed volume, breakdown volume, and breakdown curve of cross-provincial annual, monthly, and weekly transactions for E2-category electricity, as well as the breakdown curve of cross-provincial multi-day transactions for E2-category electricity; it also determines the executed volume, breakdown volume, and breakdown curve of cross-provincial annual and monthly transactions for E3-category electricity, and the breakdown curve of cross-provincial annual, monthly, and weekly transactions for E4-category electricity, as well as the breakdown curve of cross-provincial multi-day transactions for E4-category electricity.

[0079] Where N is the number of purchasing provinces participating in inter-provincial electricity trading. Statistics are compiled for each participating province, meaning each n corresponds to one purchasing province. Then, based on the annual inter-provincial electricity trading volume E of the provincial dispatch units in the inter-provincial market... 4Y,S The annual transaction volume E of the nth electricity purchasing province (Category E2) 2Y,Dn The preset proportion (1-γ) of untraded E2-class annual electricity volume transferred to E4-class annual transactions is determined by the following formula: E4-class annual transaction volume. 4S :

[0082] Next, the demand for green electricity in the nth power-purchasing province on the second preset trading date is obtained. Based on the E3 category decomposed electricity and E4 category annual trading electricity of the nth power-purchasing province on the aforementioned second preset trading date, the value of untraded green electricity flowing into other electricity markets on the aforementioned second preset trading date is determined. This untraded electricity value includes untraded green electricity, such as E1 (national mandatory plan guaranteed quantity and price), E2 (national mandatory plan guaranteed quantity and bidding electricity), E3 (green electricity), and E4 (surplus and shortage mutual assistance electricity). E3 is green electricity, while E1, E2, and E4 are non-green electricity. The aforementioned second preset trading date is month j.
