Distribution Network Efficiency Evaluation Based on Environmental Differences

doi:10.3969/j.issn.1000－7229.2016.07.016

Abstract

Abstract: To scientifically evaluate the efficiency of distribution networks and guide the planning and investment of distribution networks, this paper proposes the efficiency evaluation method with considering the environmental differences. First, we use the improved system clustering method to classify the evaluated objects; then, use the improved data envelopment analysis method （DEA） to calculate the efficiency of the evaluated distribution networks; finally, evaluate the technical efficiency of the same type of evaluated objects and propose the corresponding improvement measures and suggestions. We take the distribution networks in Zhejiang province in 2013 as examples for the analysis. The results show that the proposed efficiency evaluation method is reasonable. The efficiency of distribution networks is indeed susceptible to environmental factors; therefore, the management of distribution networks must be improved on both the input side and output side .

Key words: distribution network, efficiency evaluation, clustering, data envelopment analysis （DEA）
