Abstract: In the process of coal-fired power low-carbon transformation, new challenges emerge such as the weakening performance of carbon capture level during peak load period, the deviation between carbon quota calculation and actual application, etc. In view of these issues, the paper first introduces hydrogen fuel cells and hydrogen storage devices to formulate a comprehensive coordinated energy storage system, which can improve the insufficient carbon capture level during peak load period of carbon capture power plants; Then, the carbon quota calculation model is established, such that the calculation method of carbon quotas is more in line with practical applications; Finally, by setting the minimization of comprehensive operating cost of the system as the objective function, the optimal scheduling model of carbon capture power plants based on the comprehensive coordinated energy storage system is constructed, and the proposed model is solved using Cplex software package. The calculation results show that the carbon capture power plant can improve the carbon capture level and economy while prioritizing wind power consumption, by taking into account the low-carbon nature of the system.
