Economic Operation Evaluation of Active Distribution Network Based on Fuzzy Borda Method

Abstract

In order to make up for the shortcomings of the development of traditional distribution networks, and promote the diversification of energy structure, active distribution network (ADN) came into being. With the large amount of distributed energy resources (DER) connected to the grid, the economic operation evaluation of the active distribution network has been greatly restricted. According to the characteristics of the active distribution network, 7 second-level evaluation indicators such as DER penetration rate are defined in this paper. At the same time, combined with the indicators of the traditional distribution network, a new active distribution network economic operation evaluation index system is constructed, which includes 7 first-level indicators and 21 second-level indicators, and a comprehensive evaluation model based on fuzzy borda method is proposed. This comprehensive evaluation model is put forward due to inconsistent results of evaluation methods, in addition, Kendall-w coefficient is used for the prior consistency test, fuzzy borda method is used for the combination evaluation of different results of several evaluation methods. By considering the difference of evaluation results, the evaluation results are closer to the reality. Finally, the simulation and sensitivity analysis of the last example verify the rationality and effectiveness of the index system and the evaluation model.
