A Closed-Loop Approach to Calculate Economical Operation Indices of Distribution Network Based on Dempster-Shafer Evidence Theory
摘要
Abstract
To evaluate economical operation indices of distribution network effectively it is necessary to determine reasonable weights of operation indices, for this reason, based on Dempster-Shafer evidence theory and Spearman method a closed-loop approach to calculate the weights of economical operation indices is put forward. Firstly, the subjective index weights from experts are collected and the conflict expert opinions are rejected, and the unreliable expert opinions are processed by discount for the reliability of the evidence; then using Dempster-Shafer evidence theory the subjective weights of experts are determined. If the determined subjective weights match the sufficient conditions of evidence, these subjective weights are taken as final weights; or else the entropy method and principal component analysis are utilized to determine objective index weights, and by use of Dempster-Shafer evidence theory the comprehensive objective weights are decided. Then it is necessary to check whether the subjective weights and objective weights can meet the demand of consistency, if not, the closed-loop adjustment of weights should be performed till both subjective weights and objective weights can meet the demand of consistency.关键词
