考虑碳排放分摊的综合能源服务商交易策略

Trading strategy for integrated energy service provider considering carbon emission sharing

为寻求在满足用户用能需求的同时降低系统碳排放的有效途径,提出了一种考虑碳排放分摊的多综合能源服务商能源交易策略。基于网络流模型实现碳流追踪并联合Shapley理论建立了综合能源服务商碳排放成本计算模型。应用Nash议价理论构建了多综合能源服务商合作博弈运行模型,将综合能源服务商碳排放成本引入优化目标函数,并利用分布式算法求解最优能源交易量和交易费用。基于由修改的IEEE 39节点电网和12节点气网构成的多综合能源服务商系统进行仿真分析,验证了所提模型和方法的有效性。

In order to find an effective way to reduce system carbon emission while meeting customers’ener⁃gy demand,an energy trading strategy for multiple integrated energy service providers considering carbon emission sharing is proposed.Based on the network flow model,the carbon flow tracking is realized and the carbon emission cost calculation model of integrated energy service provider is established in conjunc⁃tion with the Shapley theory.Furthermore,the Nash bargaining theory is applied to build a cooperative game operation model for multiple integrated energy service providers,in which the carbon emission cost is introduced into the optimization objective function,and the optimal energy trading volume and transaction cost are solved by distributed algorithm.The simulation analysis is conducted based on the multiple integrated energy service provider system with the modified IEEE 39-bus grid and 12-node gas network to verify the effectiveness of the proposed model and method.
