摘　　要：针对配电网网架结构和分布式电源的规划阶段与电网运行阶段存在的交互影响作用,首先,提出了以配电网规划效益与电网运行下用户效用最优为目标的双层协同的规划运行优化框架;其次,以配电网规划中经济性与可靠性最大为目标,规划配电网网架结构与分布式电源接入节点,构建可靠性约束下配电网多目标规划模型,并基于NSGA-Ⅱ算法提出多目标配电网规划模型的求解方法;然后建立考虑电网运行阶段与用户运行调度策略下的分布式电源规划模型,提出了光伏储能规划策略与用户负荷与储能设备的运行调控策略。基于电网公司与用户之间双层规划问题,提出了一种计及电网公司与用户之间互动响应的主从博弈模型。最后,通过实际算例结果表明所提主从博弈下源网协同的规划运行模型可以有效提高电网公司与用户效益,提升电网运行可靠性。In view of the interaction between distribution network structure and distributed power generation planning stage and power grid operation stage,a coordinated planning operation model under the Stackelberg game framework and its solution algorithm between power grid company and consumers is proposed.Firstly,a bi-level coordinated planning and operation optimization framework is proposed,aiming at the optimization of the benefit of the distribution network company and utility of consumers.Secondly,aiming at the maximum economy and reliability in distribution network planning,the distribution network grid structure and distributed power access nodes are optimized.A multi-objective planning model for distribution network under reliability constraints is built,and a solution method for the multi-objective distribution network planning model is proposed based on the NSGA-Ⅱ.Then,a distributed generation planning model considering the grid operation stage and consumers’operating strategies is established,and consumers’load and energy storage equipment operation strategies are proposed.Thirdly,based on the bi-level planning problem,an Stackelberg game model is proposed which considers the interactions between the power grid company and consumers.Finally,through the simulation analysis of practical example,the results show that the proposed cooperative optimization method of distribution network planning and operation strategies under the Stackelberg game model can effectively improve the benefits of both power grid company and consumers,and further improve the reliability of power grid operation.
