基于灰色局势决策的电动汽车换电站选址研究

Research on the Site Selection of Electric Vehicle Exchange Stations based on Grey Situation Decision

新能源电动汽车的续航里程焦虑、充电桩以及公共充电站的充电等待时间过长等问题约束了新能源汽车的进一步发展,换电站是解决其问题的关键,以合肥市蜀山区为研究对象进行分析,建立换电站选址指标体系,确定权重值,利用GIS平台进行空间分析和数据可视化,初步筛选出多个高适宜性的选址点,构建多目标灰色局势决策模型对换电站选址的经济性进行分析,通过计算综合效果测度得到最终选址点。

The problems of range anxiety of new energy electric vehicles,charging piles and long waiting time for charging at public charging stations constrained the further development of new energy vehicles,and exchange stations were the key to solve their problems.Taking Shushan district of Hefei city as the research object for analysis,the index system for selecting the site of the exchange station was established,the weight values were determined,and a GIS platform was used for spatial analysis and data visualization to initially screen out several sites with high suitability.The multi-objective gray situation decision model was constructed to analyze the economics of the site selection of the exchange station,and the final site selection point was obtained by calculating the comprehensive effect measure.
