This paper introduces the calculation method of line loss of distribution network based on distributed power access,and expounds the equivalent capacity method and the forward push-back method respectively.In the introduction of the forward push-back method,further improvement is made on the basis of the traditional method,and the specific calculation steps are given.Then,taking 10 kV distribution network as an example,the technology of distribution network loss reduction after the access of distributed photovoltaic power supply is discussed,and three effective loss reduction methods are proposed to rationally select the access location,access capacity and energy storage device of distributed photovoltaic power supply.Several other technical measures with loss reduction effect are also introduced.The aim is to provide reference for power enterprises to effectively control the line loss rate of distribution network connected to distributed power supply.
