Abstract：In order to solve the problem of energy consumption optimization after photovoltaic access to the distribution network and improve itsoperation economy，this paper deeply analyzes the impact of photovoltaic access on branch power transmision，proposes a branch average power calculation method considering the influence，and improves the shortcomings of the traditional branch exchange algorithm to met the reconstruction needs of photovoltaic distributionnetwork.Through the IEEE18-node network case study，it is found thatthenewcalculationmethod can accurately reflectthe power characteristics of the branch under diferent photovoltaic powers，and the improved algorithm can determinethe optimal distribution network configuration when different photovoltaic power is connected， which significantly reduces the energy loss compared with the traditional method.
