A Practical Classification Evaluation Approach for Comprehensive Competitiveness of Distributed Energy Supply Systems

Abstract

The distributed energy supply system(DESS) is widely used in power grids. This paper proposes a practical classification evaluation approach (PCEA) based on analytic hierarchy process-entropy weight method (AHP-EWM), with the goal of the quantitative evaluation values of DESS. Firstly, a practical evaluation index system (PEIS) considering soft competitiveness and hard competitiveness is constructed and scenes of DESS are classified into types under the consideration of developmental characteristics. Then, to break the hierarchies between intertypes and improve the fairness of evaluation results, an index-contributing coefficient (ICC) based on EWM is introduced to estimate the influence degree of different indexes on classification evaluation between different types of scenes. Next, with the input valuables of practical evaluation indexes from the PEIS, the classification evaluation results of DESSs are obtained by PCEA. Finally, the DESSs in southern part of China are taken for an example for analysis and further results verify the adaptability of PCEA.
