[0002] In the global energy landscape, my country's energy structure is characterized by a significant abundance of coal and a scarcity of oil, which has led to coal-fired power generation dominating the power supply system for a long time. However, while this coal-fired power-dominated energy pattern has brought about energy supply benefits, it has also caused serious environmental problems. To achieve a win-win situation for energy development and environmental protection, it is urgent to improve the efficiency of coal-fired power generation, promote the technological upgrading and environmental transformation of coal-fired units, and reduce pollutant emissions. Furthermore, the future upgrading of coal-fired power plants towards intelligent and digital transformation is imperative, requiring the automation, intelligence, and remote control of equipment to improve operational efficiency and safety.

[0003] Among relevant technologies, there is still a lack of a precise retrofitting method for coal-fired power units that achieves carbon neutrality while maintaining optimal economic efficiency. Current technologies fail to adequately balance cost input and carbon emission reduction effects, making it difficult to achieve a deep low-carbon transformation while ensuring economic feasibility. This results in significant obstacles for coal-fired power units in their journey towards carbon neutrality.

[0004] Based on this, the present invention proposes a method and apparatus for optimizing the configuration of technical upgrades at the coal-fired power unit level to solve the problem of how to accurately calculate the technical categories that coal-fired power units need to be upgraded under the premise of ensuring economic optimization.

[0042] The first technology (covering main equipment technical transformation and auxiliary system technology) application matrix M12 extracted from the initial technology matrix initial，y The matrix has dimensions u×j 12 Since each unit may undergo renovation or not be renovated annually, a 0-1 matrix of temporary technical renovation status is generated. Its dimension is u×1. '1' indicates that the unit needs to be upgraded in that year, and '0' indicates that the unit does not need to be upgraded in that year. If If all elements are 0, then regenerate. Otherwise, continue the calculation. For 0-1 matrices... Units with the number '1' in the middle are in the corresponding technology application matrix M12 initial，y Randomly select one '0' and convert it to '1' to obtain a temporary technology application matrix. For rows where all technical modifications are complete (i.e., rows where all technologies have been applied and all elements are '1'), skip those rows and continue with the transformation of other rows. This yields the first temporary technical modification matrix.

[0065] In this embodiment, after the second technological upgrade is completed, its carbon reduction potential value needs to be compared with the industry carbon emission gap value for the target year. If the carbon reduction potential value after the second technological upgrade is less than the industry carbon emission gap value for the target year, it indicates that the current carbon emissions have not met the standard. In this case, the process of "determining the second temporary technological upgrade matrix based on the initial technology matrix" needs to be restarted to explore a better technological upgrade solution. If the carbon reduction potential value after the second technological upgrade is greater than or equal to the industry carbon emission gap value for the target year, it means that the carbon emissions meet the standard. In this case, the total investment and operating cost required for the second technological upgrade is accurately calculated based on the second temporary technological upgrade matrix.

If the first application ratio of the first technology is greater than or equal to the first preset value, it indicates that to ensure optimal efficiency, the application ratio of the second technology (including end-of-pipe carbon removal technology and source carbon reduction technology) needs to be increased. Therefore, the step of "determining the second technology matrix for the target year with the lowest emission reduction cost based on the second temporary technical upgrade matrix" is executed. Finally, the first technology matrix for the target year with the lowest emission reduction cost and the second technology matrix for the target year with the lowest emission reduction cost are combined to determine the final technical upgrade matrix.
