针对环境污染及综合能源系统中多供能主体利益冲突问题，提出了一种碳交易机制下基于合作博弈的综合能源系统经济性分析模型。为控制CO₂排放，引入碳交易机制建立了含可再生能源电厂、碳捕集电厂和燃气热电厂3个供能主体的合作博弈模型，该模型优化目标为运维成本、惩罚成本、碳相关成本和环境成本之和最小。为合理分配多供能主体的合作成本，首先采用Shapley值法进行初次分配，然后引入综合考虑成本贡献系数和环保贡献系数的修正因子对初次分配结果进一步优化，提出了改进Shapley值法分摊机制。仿真结果表明各能源主体合作运行能够有效提升新能源消纳能力、促进多能源互补利用，同时显著提高系统经济性以及降低碳排放量，采用改进Shapley值法可以使各能源主体成本分摊更加公平合理。

Aiming at the problems of environmental pollution and the conflict of interests of multiple energy suppliers in the integrated energy system, an economic analysis model of the integrated energy system based on cooperative game under the carbon trading mechanism is proposed. Firstly, in order to control CO₂ emissions, a cooperative game model with three energy supplying entities, including renewable energy power plant, carbon capture power plant and gas-fired thermal power plant, is established by introducing the carbon trading mechanism, and the optimization objective of the model is to minimize the sum of operation and maintenance cost, penalty cost, carbon related cost and environmental cost. In order to rationally allocate the cooperative costs of multiple energy supply subjects, the Shapley value method is firstly used for the initial allocation. Then, a correction factor that integrates the cost contribution coefficient and environmental contribution coefficient is introduced to further optimize the initial allocation results, and an improved Shapley value method apportionment mechanism is proposed. The simulation results show that the cooperative operation of the energy entities can effectively enhance the new energy consumption capacity, promote the complementary utilization of multiple energy sources, and significantly improve the system economy and reduce carbon emissions, and the improved Shapley value method can make the cost sharing among the energy entities more fair and reasonable.
