Given the goal of “dual-carbon”, to improve the utilization efficiency of wind and solar energy, optimize the allocation of resources and promote the carbon reduction of the integrated energy system (IES), a low-carbon economic scheduling model of a wind, solar, and hydrogen storage integrated energy system is proposed. First, considering the low-carbon characteristics and dispatching advantages of hydrogen energy as a new type of energy storage, a two-stage operation P2G model is introduced to realize the coupled transfer between electricity, heat and gas energy in the system with hydrogen energy as the connecting link. Secondly, carbon capture equipment and a stepped carbon trading mechanism are introduced to further reduce the carbon emission of the system. Then, a low-carbon economic dispatching objective is constructed to minimize the energy purchase, carbon trading, operational and wind and light abandonment costs, and the CPLEX solver is used to solve the problem. Finally, by comparing and analyzing the optimal results of several operating scenarios, the effectiveness of the model in absorbing wind and solar power output, promoting deep decarbonization of the system, promoting multi energy complementarity, and increasing system economic benefits are verified.
