A comprehensive assessment of the electric vehicle load impact on distribution network based on fuzzy Borda method
The rapid development of the electric vehicle industry will definitely bring great pressure to the power grid operation,which needs to be tackled by the precise study of the electric vehicles impact on the distribution grid. Therefore,this paper constructs a spatial and temporal distribution prediction model of EV charging load and a comprehensive evaluation system of EV access to the distribution network. Firstly,multi-source data,multi-factor energy consumption model,dynamic road network model and road-electricity coupling theory are used to predict the spatial and temporal distribution of EV charging load. Secondly,a comprehensive evaluation system is established by constructing quantitative indicators based on five criteria:rationality,safety,economy,reliability and environmental protection. Thirdly,the comprehensive weighting method is applied to obtain the index weight set,and the fuzzy Borda method is applied to synthesize various comprehensive evaluation methods in order to obtain the comprehensive evaluation results. Finally,the feasibility of the proposed method is proved by simulating a case in a region of Shanghai.
