摘　　要：多个园区微网综合能源系统接入同一配电区域形成多微网综合能源系统,当多微网之间存在能量交互时,多微网之间的利益交互关系给多微网综合能源系统的运行和规划带来了挑战。文章提出一种基于P2P交易和储能寿命循环的多微网综合能源系统分布式低碳优化运行策略。首先,综合考虑多微网综合能源系统中储能的寿命问题与各微网信息交互的因素,构建多微网综合能源系统的运行模型。其次,基于交替方向乘子法(alternatingdirection method ofmultipliers,ADMM)和纳什判断先后对微网联盟运行成本最小和多微网支付效益最大化这2个子问题进行求解。最后,通过算例对比证明了所提方法在提升个体效益和社会效益上具有一定的经济性。Multiple park microgrid integrated energy systems are connected to the same distribution area to form a multi-microgrid integrated energy system,and when there is energy interaction between the multi-microgrids,the interaction of interests between the multi-microgrids poses challenges to the operation and planning of the multi-microgrid integrated energy system.This paper proposes a distributed low-carbon optimization operation strategy for multi-microgrid integrated energy system based on P2P trading and energy storage life cycle.First,the operation model of the multi-microgrid integrated energy system is constructed by comprehensively considering the lifetime problem of energy storage in the multi-microgrid integrated energy system and the factors of information interaction of each microgrid.Second,the subproblems of minimizing the operation cost of the microgrid alliance and maximizing the payment benefit of multiple microgrids are solved successively based on the alternating direction method of multipliers(ADMM)and Nash judgment.Finally,the comparison of arithmetic examples proves that the proposed method is economical in enhancing individual and social benefits.
