摘　　要：含高渗透率分布式电源的微电网(HP-DGMG)中,分布式电源(DG)的不确定性会对投标收益产生影响,甚至增加微电网和配电网的运行风险。考虑HP-DGMG中分布式光伏的不确定性,文中提出一种基于分布鲁棒机会约束(DRCC)的有功-无功投标交易策略。首先,考虑HP-DGMG售电与购电两种市场交易特性,构建配电市场环境下HP-DGMG的投标与交易框架,进一步建立配电市场下HP-DGMG有功-无功交易的双层投标模型。其次,引入DRCC处理微电网中分布式光伏发电的不确定性,构建基于矩信息的HP-DGMG有功-无功投标分布鲁棒优化模型,利用条件风险价值理论和对偶理论,将HP-DGMG投标分布鲁棒模型转化为二阶锥规划形式。然后,利用原-对偶counterpart方法,提出考虑光伏不确定性的配电市场环境下HP-DGMG投标的单层均衡约束数学规划模型,并转化为混合整数二阶锥规划问题进行求解。最后,通过位于7节点配电网和33节点配电网的HP-DGMG进行分析验证,结果验证了所提HP-DGMG投标交易策略的有效性。In high penetration-distributed generator microgrid(HP-DGMG),the uncertainty of distributed generator(DG)can have an impact on bidding revenues and even increase the operational risk of HP-DGMG and distribution networks.Considering the uncertainty of distributed photovoltaic in HP-DGMG,an active and reactive power bidding and transaction strategy of microgrid based on distributionally robust chance constraint(DRCC)is proposed in this paper.Firstly,considering the power sale and power purchase transaction characteristics of HP-DGMG,the bidding and transaction framework of HP-DGMG in the distribution market environment is constructed,and the bi-layer bidding model of HP-DGMG active and reactive power transactions in the distribution market is further established.Secondly,DRCC is introduced to deal with the uncertainty of distributed photovoltaic power generation in microgrid,and the optimization model of HP-DGMG active-reactive power bidding and transaction based on the moment information is constructed.By using conditional value-at-risk theory and duality theory,the distributionally robust model of HP-DGMG bidding and transaction is transformed into second-order cone programming form.Then,a single-layer mathematical program with equilibrium constraint(MPEC)model of HP-DGMG bidding in distribution market environment considering photovoltaic uncertainty is proposed by using primal-dual counterpart method,and it is converted into mixed-integer second-order cone programming problem for solving.Finally,the HP-DGMG located in 7-bus distribution network and 33-bus distribution network is analyzed and verified,and the effectiveness of the proposed HP-DGMG bidding and transaction strategy is verified.
