Abstract：Connecting the microgrid system to the larger grid not only ensures the reliability of the islanded operation,but also improves the economic efficiency of the system.The optimal configuration of each microelement in microgrid is an important research direction in this field.In this study,a microgrid system with mainstream micro-element structures such as solar photovoltaic arrays,wind turbines and energy storage batteries is first built,and an optimization problem with economic cost minimization and system redundancy is proposed as the objective function.Secondly,the improved optimization algorithm combining genetic algorithm and particle swarm optimization algorithm is used to solve the multi-objective optimization problem.Finally,a practical example is given to analyze the multi-objective optimal configuration of grid-connected microgrid system,and the effectiveness of the proposed method is verified.
