Comprehensive Evaluation of Distribution Network Reliability for Power Consumer Based on AHP and Entropy Combination Method

In order to solve the problem that the current index system of distribution network reliability for power consumer (DNRPC) is not yet perfect, the index system is expanded in this paper, and a comprehensive evaluation method of DNRPC based on analytic hierarchy process (AHP) and entropy combination method is put forward. Firstly, the concept and connotation of DNRPC are expanded. Secondly, three new evaluation indexes are proposed to expand the existing index system. Thirdly, AHP method and entropy method are used to determine the subjective and objective weight of the reliability indexes. The least squares method is used to optimize the index weight and obtain the comprehensive evaluation result. Finally, a concrete example is given to demonstrate the validity and feasibility of the proposed index system and the comprehensive evaluation method.
