Research on Flexible Reliability Evaluation of Distribution Network System with Distributed Energy Access

Abstract

Access to distributed energy has brought a greater impact on the system. By analyzing the flexibility of the distribution network itself, considering the evaluation indicators of the three dimensions of effect, degree and service, this paper designs a flexible reliability evaluation index system for the distribution network, using principal component analysis and multi-level fuzzy comprehensive evaluation thoughts, a flexible reliability model was established, and calculation examples were analyzed, which is helpful to provide guidance for the development of regional distribution networks.
