Abstract
To utilize the objective information of index data and consider the important role of subjective judgment in the evaluation of distribution automation equipment testing results, a comprehensive evaluation method based on AHP (Analytic Hierarchy Process) and CRITIC (CRiteria Importance Through Intercriteria Correlation) method is proposed. Firstly, an evaluation index system of distribution automation equipment testing results considering seven big indicators and thirty-six small indicators is established. Secondly, AHP and CRITIC method are adopted to solve a practical evaluation problem of distribution automation equipment testing results. The subjective weights of each evaluation index are calculated by AHP, the objective weights of each evaluation index are calculated by the CRITIC method. Then, to achieve the sorting of distribution automation equipment testing results accurately, the comprehensive weights are obtained by combining the two weights. Finally, the analysis and comparison of case studies show that the proposed evaluation index system can accurately reflect the performance of distribution automation equipment and the comprehensive evaluation method of distribution automation equipment testing results which comprehensively considers the subjective comprehensive evaluation results.
Highlights
With the development of smart distribution network, the distribution automation equipment has been widely popularized, and the number of distribution automation equipment is increasing[1]
Because the comprehensive weights calculated by combining the subjective weights and the objective weights are more reasonable and scientific, the proposed method has the advantage that both the objective information of index data and the important role of subjective judgment are fully utilized
This paper proposes a comprehensive evaluation method of distribution automation equipment testing results based on AHP (Analytic Hierarchy Process) and CRITIC (CRiteria Importance Through Intercriteria Correlation) method
Summary
With the development of smart distribution network, the distribution automation equipment has been widely popularized, and the number of distribution automation equipment is increasing[1]. It is significant to reasonably evaluate the distribution automation equipment in ensuring the safe operation of the energy system Both subjective and objective factors are fully utilized to make the weighting process more reasonable and output the accurate and comprehensive evaluation results of distribution automation equipment. The evaluation method of distribution automation equipment testing results generally include analytic hierarchy process[5]. AHP and CRITIC method are adopted to solve a practical evaluation problem of distribution automation equipment testing results. The subjective weights of each evaluation index are calculated by AHP[7], the objective weights of each evaluation index are calculated by CRITIC method[8]. To achieve the sorting of distribution automation equipment testing results accurately, the comprehensive weights are obtained by combining the two weights.
