Research on Comprehensive Weight Determining Method for Evaluating Operation State of Distribution Network

In order to comprehensively evaluate the operation state of the distribution network, a method to determine the weight of the evaluation indexes is proposed by using AHP method and entropy method in this paper. Firstly, the evaluation index system of operation state for distribution network is established. Then AHP method is used to calculate the subjective weights and entropy method is used to calculate the objective weights. The comprehensive weights are calculated by using the subjective weights and the objective weights so as to ensure the scientificity for determining the weights. This method overcomes the disadvantage that the existing entropy method can be only used in multi\|scheme planning, and entropy is used in single scheme planning. In the end, the comprehensive evaluation result is calculated according to the scores and weights of the indexes. And a numerical example is used to prove the effectiveness and rationality of the method.
