Analytic hierarchy process, fuzzy comprehensive evaluation, electromagnetic loop circuits


Electromagnetic loop circuits may jeopardize the power system safety operation. A fuzzy comprehensive evaluation method based on analytic hierarchy process is presented in the paper for electric power network operating schemes. The analytic hierarchy process is used to analyze influencing factors, establish a hierarchical model and rank the influencing factors in order of importance. Performance indices and membership functions corresponding are presented to denote their contributions on overall objective. Quantitative evaluation results that considering various factors comprehensively are obtained by a two-level fuzzy comprehensive evaluation. Some simulation results of Shandong power system in China demonstrate the proposed method can be used to evaluate power network operating schemes.
