In recent years

active distribution network planning based on peak load is an important research direction. This paper considers the use of photovoltaic power generation to access the distribution network for peak shaving

so as to solve the problems of low equipment utilization and waste of investment caused by the layout of the traditional distribution network according to the maximum load planning method. Under the maximum load level

the active distribution network planning modeling and algorithm design are carried out considering the peak regulation of distributed power supply. The advantages of flexibility

convenience and investment saving are verified by examples.
