There is a problem that a large number of photovoltaic power supplies are connected to the grid,the voltage may ex-ceed the limit.Therefore,this paper analyzes the impact on the distribution network after photovoltaic power supply is con-nected,and comprehensively considers the requirements of multi-objective optimization such as the highest penetration rate,the lowest loss and the best voltage governance of photovoltaic power supply,and then a mathematical model of photovoltaic power supply configuration optimization taking into account the source load matching characteristics is established.A double criteria differential evolution algorithm based on the individual fitness evaluation principle and the cooperative decomposition criterion is proposed to solve the distribution problem of the target value,and improve the convergence ability of the target space.The re-sults of an example show that the proposed method can reduce the configuration cost by more than 9％,and has higher accuracy and practicability.
