Abstract：With the upgrading of the"dual carbon"target to a national strategy,coal-fired power plants,as the top priority for reducing carbonemissions in the power generation industry,face enormous challenges in limiting carbon emissions.In response to the carbon emission issues and cost control requirements in thermal power production,the paper constructs a bi-level programming coal blending optimization model strategy that integrates carbon emissions and economic analysis.This optimization aims to find the optimal balance between reducing environmental impact and saving costs,ensuring systematic and multi-dimensional evaluation of the decision-making process,and providing practical coal blending strategies for the management of thermal power plants.The simulation optimization results of 10 commonly used single coal co firing strategies in a thermal power plant in Guizhou show that,considering certain economic benefits,this optimization strategy can improve the power generation efficiency of the thermal power unit by up to 4％and effectively reduce carbon emissions by 6.6％,providing a new method for the thermal power industry to respond to the national"dual carbon"strategy and promote low-carbon and efficient power generation transformation.
