Comprehensive Evaluation of AC/DC Distribution Network of Flexible Substation Based on Triangular Fuzzy Analytic Hierarchy Process

With the improvement of energy utilization level, how to efficiently realize power distribution has become a key research problem. In order to solve the problems of low conversion efficiency and serious power loss of traditional rigid distribution network, AC-DC distribution network technology based on flexible transformer station was implemented. This paper sets up a comprehensive evaluation index system including 11 first-level indexes and 26 second-level indexes from five aspects of technical performance, economic benefit, environmental impact, social benefit and policy impact. The triangular fuzzy analytic hierarchy process is used to establish a fuzzy comprehensive evaluation, and the technical and economic performance of AC/DC transmission technology based on flexible transformer station is analyzed, which provides a reference basis for later project development.
