A Method for Analyzing Boundary Conditions of Typical Power Supply Structure in AC/DC Hybrid Distribution Network with Large-scale Photovoltaic Access

In the situation of high proportion of distributed energy access, AC/DC hybrid distribution network has lower network loss and more flexible regulation ability than traditional AC distribution network. In order to provide relatively accurate guidance for AC/DC construction of distribution area, it is necessary to analyze its characteristic index boundary conditions. In this study, under the background of high percentage of photovoltaic access, the operation economy, photovoltaic consumption, power supply quality and other evaluation indexes of AC/DC hybrid distribution network were comprehensively considered, and the intelligent optimization algorithm was used to regulate the flexible equipment, and the boundary conditions of three characteristic indexes of photovoltaic permeability, power supply radius and load capacity were analyzed.
