Comprehensive location evaluation of multi-station integration

Abstract

Multi-station integration realizes the optimal usage of multiple energy by integrating the functions of substations,photovoltaic power stations,charging stations and other stations,but the location evaluation needs to take into account the influence factors. In the location evaluation weight design,it is difficult to design characteristic indices and common indices for each single station. The common indexes have different degrees of influence on each single site. To solve the problem,a method for the construction of multi-station integration location evaluation index system is designed. Also,the integration of each single station indices is realized. At the same time,the combination weight calculation method based on the analytic hierarchy process and multi-station index system is designed. Firstly,the weights of all indices are calculated for all single stations. Then the weights of the single station are designed. Finally,two weights are combined to get the combination weights of all indices. The fuzzy comprehensive evaluation method is used to score each index of the candidate sites,and the optimal site is selected after a comprehensive evaluation considering the weight. The effectiveness of the proposed evaluation system and method is verified by an example.
