[0022] like Figure 1As shown, the green certificate transaction matching method for a power generation group provided in an embodiment of the present invention mainly includes the following steps: 101. Through the product library model, it is determined that in one transaction matching, multiple renewable energy sites of the power generation group participate in the green certificate transaction matching, and the amount of green certificates participating in the matching is determined.

[0023] The digital management and control method of green certificates for large power generation groups is used to integrate data information from platforms such as the green certificate issuance and trading system, the green power certificate trading platform, and the enterprise site information collection system, so as to achieve unified management of the green certificate application and trading work under the enterprise. It includes file establishment and carding, green certificate application process control, product library management, transaction task matching, transaction process control, and data statistical analysis. Among them, transaction task matching includes the green certificate demand management function, that is, to classify and control the green certificates that can be sold according to the source of green certificates, time tags, project types, etc., as an important data source for the formulation of transaction tasks. The above-mentioned functional matching generates transaction tasks that meet the requirements.

[0024] Specifically, in In one match, the power generation group Renewable energy sites participate in green certificate trading matching, determine the green certificate spot holdings and projects of each renewable energy site Issuance vector; Based on the green certificate spot holdings of each renewable energy site and the issuance vector of the project, determine the green certificate inventory matrix for the project to participate in the matching.

[0025] The amount of green certificates participating in the matching is defined as (1): (1) in, Indicates the green certificate spot holdings of each renewable energy site, Indicates power station exist month Monthly green certificate inventory, for The earliest month that a project starts to be issued, the project issuance vector is (2): (2) Then the green certificate inventory matrix of the project participation matching is (3): (3) Then, based on the green certificate inventory matrix and the monthly issuance characteristics of green certificates, determine the amount of green certificates involved in matching as spot or futures.

[0026] According to the characteristics of green certificates being issued monthly, it is assumed that the matching occurs Month, the amount of green certificates involved in the matching is determined to be spot or futures, including: when Monthly, determine the amount of green certificates participating in the matching All are spot goods, and the data source is the green certificate issuance and trading system and other platform systems that contain the final number of green certificates issued. Indicates k Month labels of the green certificate products participating in the matching.

[0027] when Monthly, determine the amount of green certificates participating in the matching All are futures. Indicates total n Months of participation in matching, n Monthly labels of green certificate products participating in the matching. The forecast output for the month minus the Monthly participation in matching green certificate futures. Among them, the predicted output can be The monthly power generation plan, planned grid-connected power and green power trading power are initialized.

[0028] The forecasted output is obtained by: For centralized photovoltaic power stations, wind farms and tidal power stations, the predicted output is determined by the grid-connected power plan and green power trading volume, as shown in formula (4); (4) in, Indicated in Month Monthly planned online electricity consumption, Indicated in Month The amount of green electricity traded in the month.

[0029] For industrial and commercial distributed photovoltaic and household photovoltaic sites, there is generally no grid-connected power plan. The power generation plan and historical self-use rate are used to obtain the predicted output, such as (5): (5) in, represents the historical self-consumption rate, Indicated in Month Planned power generation for the month.

[0030] The calculation method of historical self-consumption rate should be based on the following method: (1) The production situation of industrial and commercial electricity users is stable and the electricity consumption is stable; (2) Distributed photovoltaic power generation is based on the principle of generating as much power as possible and connecting the remaining power to the grid. The power generation only considers seasonal changes and ignores the impact of abnormal weather, power restrictions, equipment failures and other factors; (3) When the number of historical months involved in the calculation is greater than When the historical electricity consumption rate converges, Represents the convergence threshold constant.

[0031] In Month, when The number of historical data in the same month When the historical electricity consumption rate of that month is taken as the historical electricity consumption rate; when When the inclusion range needs to be expanded to the same quarter, the included quantity is ;when When extended to the year, the amount included is ;when When expanded to the same province, the number included is ;when When expanded to the same province's industrial and commercial distributed photovoltaic projects, the number of included ;when When extended to all industrial and commercial distributed photovoltaic projects in the system, the number of included ; In other cases, the default value of a random number between 60% and 80% is used for estimation. The expression is as follows (6): (6) in, , It refers to the power generation and grid-connected electricity within the scope of all industrial and commercial distributed photovoltaic projects (fb) in the same month (sm), quarter (ss), year (sy), province (sp).

[0032] 102. Determine the total demand for green certificates from multiple enterprises received by the power generation group through the demand model.

[0033] exist The monthly power generation group received The total demand for green certificates of enterprises is (7): (7) in, , Indicates j The green certificate demand of the first-class demand enterprises, Indicates j The demand for green certificates of the second-category demand enterprises is Indicates j The green certificate demand of the third type of demand enterprises, represents the number of enterprises with the first type of demand, represents the number of enterprises with the second type of demand, represents the number of enterprises with the third type of demand, Indicates the serial number of the enterprise requiring the green certificate.

[0034] According to the characteristics of green certificate demand, it is mainly divided into the following three categories and sorted by category: (1) Enterprises ( ) When the green certificate demand has no production time requirement, it is classified as the first type of demand, such as (8): (8) in, Indicates the green certificate demand of the first type of demand enterprise, Indicates j The green certificate demand of the first-class demand enterprises, Indicates The green certificate demand of the first-category demand enterprises.

[0035] (2) When the enterprise ( ) The green certificate production date is required to be later than The transfer deadline is , For the j The starting month for the production of green certificates required by the second-category demand enterprises, For the j The green certificate production termination month required by the second-category demand enterprise is classified as the second-category demand, such as (9): (9) in, Indicates the green certificate demand of the first second-category demand enterprise, Indicates j The demand for green certificates of the second-category demand enterprises is Indicates The green certificate demand of the second category of demand enterprises.

[0036] The transfer time interval is (10): (10) in, Indicates the starting month of green certificate production required by the first second-category demand enterprise. Indicates The starting month for the production of green certificates required by the second-category demand enterprises, Indicates the end month of green certificate production required by the first second-category demand enterprise. Indicates The month in which the production of green certificates required by the second-category demand enterprises ends.

[0037] (3) When the enterprise When there is a requirement for a specific production month for the green certificate, it is classified as the third category of demand, such as (11) (12) (13): (11) in, Indicates the green certificate demand of the first third-category demand enterprise, Indicates j The green certificate demand of the third type of demand enterprises, Indicates The green certificate demand of the third category of demand enterprises.

[0038] (12) in, Indicates j The third type of demand enterprises t The demand for green certificates in January, Indicates j The third type of demand enterprises t k Monthly production of green certificates demand, Indicates j The third type of demand enterprises t n Monthly production demand for green certificates.

[0039] but: (13) in, For Enterprises exist Monthly green certificate demand, Indicates that the first third-category demand enterprise t The demand for green certificates in January, Indicates The third type of demand enterprises j right t The demand for green certificates in January, Indicates the first third-category demand enterprise j right t n Monthly production of green certificates demand, Indicates The third type of demand enterprises t n Monthly production demand for green certificates.

[0040] Located in Matching, station exist Green certificate products are provided to enterprises The transaction volume is , , , .

[0041] 103. Based on the quantity of green certificates involved in matching and the total demand for green certificates of multiple enterprises, the transaction matching plans are classified through a constraint model that includes the quantity of green certificates and the production time of green certificates.

[0042] According to the main trading principles of green certificate trading, the matching schemes are classified, and the matching tensor is assumed to be (14): (14) Among them, the station of Issue green certificates to enterprises The transfer amount is , The dimension is A third-order natural number matrix.

[0043] The constraint model includes the following constraints: (1) Station exist The monthly transfer of green certificates cannot be higher than the stock and planned production, such as (15): (15) in, represents the number of demanding enterprises, Indicates the serial number of the demanding enterprise. Indicates station i To enterprises j Transfer t k The amount of green certificates produced per month.

[0044] (2) Orders that meet the requirements of the green certificate production month are matched according to the requirements, such as (16); (16) in, Indicates The third type of demand enterprises t k Monthly production demand for green certificates.

[0045] (3) For orders with green certificate production date range requirements, match them according to the requirements, such as (17): (17) in, Indicates The starting month for the production of green certificates required by the second-category demand enterprises, Indicates The end month of green certificate production required by the second-category demand enterprises, Indicates j The green certificate demand of the second category of demand enterprises.

[0046] The deadline for matching transfer here is The reason is that a backup green certificate production month is reserved. The actual production of green certificates is different from the planned production, and other unmet green certificate needs are adjusted to this month. The number of backup months can be adjusted according to actual production conditions.

[0047] (4) For orders without time attribute requirements, match them according to the requirements, such as (18): (18) in, Indicates j The green certificate demand of the first-category demand enterprises.

[0048] 104. Based on the classified transaction matching plan and combined with the functional model of transaction characteristics, determine the green certificate transfer amount and planned freeze amount to complete the current green certificate transaction.

[0049] Through the green certificate transfer, a two-way contract is signed to stipulate the transfer amount, and the contract transfer vector is determined as (19); (19) in, Indicates the number of months involved in the matching. Indicates k Month labels.

[0050] The objective function is mainly divided into the following types according to the characteristics of green certificate transactions: (1) In order to reduce the number of two-way contracts signed, it is preferred not to split the order, that is, the contract transfer vector The L0 norm reaches its minimum value (20): (20) (2) The first-in-first-out (FIFO) constraint ensures that the first issued green certificates are sold first, as shown in (21): (twenty one) Single-objective optimization or multi-objective optimization can be performed according to business needs. The multi-objective optimization method can be linear weighted method, main objective method, approximate objective method, etc.

[0051] The stock matrix after transfer is , satisfying (22): (twenty two) in, Indicated in Monthly transfer to the back station i of Monthly production of green certificate inventory.

[0052] According to The planned frozen amount obtained by generating the matching plan for the month is (23): (twenty three) in, express Monthly Enterprise of Monthly production of green certificates frozen, Indicates the date is moon.

[0053] 105. When the transaction matching is advanced to the next time, if the difference between the actual issuance volume of green certificates and the green certificate futures, as well as the adjustment of the production plan, causes the change of the planned volume of green certificates, resulting in the original plan not meeting the matching requirements, the transaction issuance inventory will be adjusted to ensure the completion of the next transaction matching.

[0054] As the business process progresses, the current month advances to During the month, the difference between the actual issuance volume of green certificates and green certificate futures, and the change in the planned volume of green certificates due to the adjustment of the production plan may cause the original plan to fail to meet the matching demand, and adjustments will need to be made.

[0055] Therefore, it is necessary to make adjustments and judgments. The power generation plan, grid-connected power plan, and holding volume will be adjusted according to the actual issuance volume, actual transfer volume, and plan change volume, specifically: exist Month, if Months before the current month are for spot sales, and the frozen quantity is equal to the sales quantity. Keep the update before and after The green certificate holdings in the month remain unchanged, so Monthly green certificate stock is (24): (twenty four) in, Indicates power station i exist Monthly plan quantity updated before demand adjustment t k Monthly green certificate inventory, Before adjustment Monthly Enterprise i of The frozen amount of green certificates produced monthly.

[0056] The update plan has no impact on spot, so after the update plan The green certificate holdings for the month remain unchanged, such as (25): (25) in, Indicates power station i exist Monthly plan quantity updated before demand adjustment t k Green certificate inventory for the month.

[0057] exist Month, if Months after January are futures, and they are iterated as the production plan is adjusted. Monthly power generation plan updated monthly Internet power plan Green power trading volume and self-use rate forecast output, and update Monthly futures inventory and Monthly green certificate holdings, such as (26): (26) So after updating the plan The green certificate holdings for the month are (27): (27) express forecasted production.

[0058] This month, when When the green certificate is issued, it is determined whether the current holding volume meets the transaction matching volume after the issued volume is redeemed and before the transaction is transferred, as shown in (28): (28) in, Indicates station Received The actual issuance volume of green certificates in a month.

[0059] like , then you need to make adjustments and directly transfer transactions. The stock matrix after adjustment and transfer is: , satisfying (29): (29) in, Indicates power station i exist +1 month t k Green certificate inventory for the month.

[0060] After adjustment, according to The planned freezing amount obtained by generating the matching plan for the month is (30): (30) like , the unmet demands are adjusted and the transactions are matched again.

[0061] After the transaction is issued and the stock is adjusted, the transaction matching process can be repeated. In the process of repeating the transaction matching process, in order to reduce the adjustment amount and thus reduce the number of supplementary contracts, it also includes: using relative Monthly matching deviation minimization strategy, such as (31): (31) in, Indicates the power station after adjustment of Issue green certificates to enterprises The transfer amount. Single-objective optimization or multi-objective optimization can be performed according to business needs. The multi-objective optimization method can be a linear weighted method, a main objective method, an approximate objective method, etc.

[0062] As for other processes, we will not describe them in detail. You can refer to the processes before adjustment for understanding.

[0063] By adopting the transaction matching method of the present invention, transaction matching is performed through an automated process, which improves the intelligence level of green certificate transactions and can effectively avoid the defects of chaotic transaction management and low transaction efficiency.
