[0037] Step 112: Determine the final technical transformation matrix based on the first technology matrix in the target year with the minimum first emission reduction cost and the second technology matrix in the target year with the minimum second emission reduction cost.

[0038] In this embodiment, first, industry data and an initial technology matrix for the initial year are obtained. The industry data includes the total installed capacity of coal-fired power generation, the total power generation of coal-fired power generation, the annual average utilization hours of the industry, and the coal consumption value for power generation in the industry.

[0041] In the formula, M initial,y is the initial technology matrix, y 0 is the initial year, y is the target year, is the application situation of technology j of unit u in the initial year y o of.

[0042] If the target year y is equal to the initial year y 0 , then according to the application situation o of technology j of unit u in the initial year y (1 represents that the technology has been applied to the unit, 0 represents not applied) to construct the initial technology matrix, the size of the matrix is u×j, where u is the number of units and j is the number of technology types; if the target year y is not equal to the initial year y 0 , then use the technology matrix M of the (y - 1)-th yeary-1 As the initial technology matrix for the y-th year.

[0043] The first technology (covering the technical transformation of the main equipment and the auxiliary system technology) application matrix M12 extracted from the initial technology matrix initial,y , with the matrix dimension of u×j 12 , since there are two situations of transformation or non-transformation for each unit per year, a temporary technical transformation status 0-1 matrix is generated whose dimension is u×1. '1' means that the unit needs to be transformed in that year, and '0' means that the unit is not transformed in that year. If all elements of are 0, then regenerate otherwise continue the calculation. For the 0-1 matrix for the units with the number '1' in the matrix, randomly select 1 '0' in the corresponding technology application matrix M12 initial,y and convert it to '1' to obtain the temporary technology application matrix For the rows where all technical transformations are completed (i.e., the rows where all technologies have been applied, and all elements of this row are '1'), skip this row and continue the transformation of other rows. In this way, the first temporary technical transformation matrix can be obtained

[0044] In an embodiment of the present invention, the first temporary technical transformation matrix includes the temporary technical transformation matrix for the technical transformation of the main equipment and the temporary technical transformation matrix for the technical transformation of the auxiliary system;

[0045] The second temporary technical transformation matrix includes the temporary technical transformation matrix for end-of-pipe carbon removal technology and the temporary technical transformation matrix for source carbon reduction technology.

End-of-pipe carbon removal technology: Carbon capture, storage and utilization technology; the setting status of the source carbon reduction technology temporary technical transformation matrix is used to represent whether the coal-fired power unit needs to carry out the technical transformation and upgrade of the source carbon reduction technology.

If the carbon emission reduction potential value after the first technological transformation is less than the industry carbon emission gap value of the target year, it indicates that the current carbon emission does not meet the standard. At this time, it is necessary to restart the process of "determining the first temporary technological transformation matrix according to the initial technology matrix" to explore a better technological transformation plan. If the carbon emission reduction potential value after the first technological transformation is greater than or equal to the industry carbon emission gap value of the target year, it means that the carbon emission meets the standard.

[0067] According to the second emission reduction cost, determine the second technology matrix in the target year with the minimum second emission reduction cost.

[0068] In this embodiment, after the second technological transformation is completed, it is necessary to compare and judge the carbon reduction potential value with the industry carbon emission gap value in the target year. If the carbon reduction potential value after the second technological transformation is less than the industry carbon emission gap value in the target year, it indicates that the current carbon emissions do not meet the standards. At this time, it is necessary to restart the process of "determining the second temporary technological transformation matrix according to the initial technology matrix" to explore a better technological transformation plan. If the carbon reduction potential value after the second technological transformation is greater than or equal to the industry carbon emission gap value in the target year, it means that the carbon emissions meet the standards. In this case, based on the second temporary technological transformation matrix, accurately calculate the total investment operation cost required for the second technological transformation. Then, relying on the total investment operation cost required for the second technological transformation and the carbon reduction potential value after the second technological transformation, use a specific algorithm to determine the second emission reduction cost. Finally, based on the second emission reduction cost, among the many possible second technology matrices in the target year, select the matrix that minimizes the second emission reduction cost.
