Linking carbon-green certificate trading with the comprehensive demand response mechanism will help optimize user energy usage behavior and reduce carbon emissions from the integrated energy system. In this background, a method is proposed to link the carbongreen certificate trading-demand response mechanism with the cooperative game, and the alliance breakdown problem caused by the interest distribution mechanism in the cooperative game is analyzed. First, each park is the main body to form a cooperative game alliance. Second, the carbon trading mechanism, green certificate trading, comprehensive demand response mechanism and cooperative game model are linked to promote the active consumption of renewable energy in the alliance by each park in the integrated energy system. Reduce carbon emissions. Then, in order to ensure the success of the cooperative alliance, an improved benefit distribution method is proposed. Finally, through actual case simulation analysis, the method of linking the carbon-green certificate trading-demand response mechanism and cooperative game promotes the low-carbon economic operation of the integrated energy system, and through improved profit distribution methods, the enthusiasm of each park to participate in the alliance has been increased on the basis of a stable alliance.
