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.
