This invention relates to the field of energy and power system planning and evaluation technology, specifically to an evaluation method, apparatus, and equipment for clean and low-carbon transformation technology paths of coal-fired power. In this invention, by integrating the full life-cycle carbon emission data of multiple technology paths and simulating the dynamics of actual power supply and demand through operational simulation, both the carbon emission per kilowatt-hour and the levelized cost per kilowatt-hour of the transformation path are simultaneously used as optimization objectives, with load fulfillment rate as a constraint. Using a multi-objective optimization algorithm, a series of Pareto optimal paths can be automatically identified under a given scenario. These paths clearly reveal the trade-off between cost and emission reduction, thereby helping decision-makers select transformation strategies that achieve the optimal balance between carbon emissions and power generation costs while ensuring a safe and reliable power supply. This provides accurate and reliable quantitative basis for the coal-fired power industry to formulate a low-carbon development path that is both environmentally friendly and economically feasible.
