Planning Method of Low-Voltage Distribution Network Applicable to the Access of Multiple Flexible Entities

Abstract

Since the establishment of the goal of “peak carbon and carbon neutrality”, various types of emerging loads have been developing rapidly. However, the application scenarios and working principles of various loads are different, and there is no clear standard for distribution network requirements. Thus, the existing low-voltage distribution network planning methods do not take emerging loads into account. Therefore, this paper proposes a low-voltage distribution network planning method that is applicable to the access of multiple flexible subjects. Firstly, the operational characteristics of flexible resources on the power side, user side, and energy storage side are analyzed and studied. Secondly, the low-voltage distribution network planning method applicable to the access of multiple flexible subjects is studied. Finally, the low-voltage distribution network of Song Yang County, Lishui City, is selected for the empirical application.
