摘要
多个临近的微电网之间在怎样的条件下会主动形成合作,对微电网和配电网的演化发展均具有重要意义.本文采用联盟型博弈方法对考虑停电风险的多微电网合作判据展开研究.基于上级配电网停电时间概率分布和各停电时间下微电网联盟的停电损失,提出了微电网联盟停电风险的计算方法.搭建了考虑停电风险的多微电网系统联盟型博弈模型,从合作产生额外收益和收益分配两个层面分析了有关性质,提出了多微电网进行合作的判据.通过对猫儿山多微电网系统等4个多微电网系统的仿真分析,验证了微电网之间储能和负荷分布不均匀可促成多微电网形成合作以降低停电风险,证明了所提合作判据的正确性.
Cooperation condition of multiple adjacent microgrids is important to evolution and development of microgrids and distribution systems. This paper focuses on multi-microgrids cooperation criterions considering outage risk using coalitional game approach. Evaluation method of microgrid coalition outage risk based on probability distribution of interruption duration and outage loss is proposed. Coalitional game model for multi-microgrids considering outage risk is set up,and its characters are analyzed through the aspects of extra profit brought by cooperation and payoff allocation. Criterion of microgrids cooperation is put forward. Case studies of Mao＇er Hill multi-microgrids and other three multi-microgrids verify the correctness of the proposed cooperation criterion. The results reveal nonuniformity of multiple microgrids in storages and loads may encourage cooperation to reduce outage risk.
