Research on Location and Capacity of Electric Vehicle Charging Station based on VORONOI Diagram

With the acceleration of China's industrialization process, the energy crisis and environmental pollution are becoming more and more serious, which driving the rapid development of the new energy industry and the diversification of energy using methods. Electric vehicles with energy saving and emission reduction characteristics have become an important solution to this problem. In view of the development characteristics of electric vehicle charging stations in the future, the paper establishes the location selection of charging stations with the lowest comprehensive cost in the whole society based on the operation and maintenance construction costs, annual profits of charging stations, and users' annual charging fees, body wear, and time costs. multi-objective optimization model. According to the designed site selection and capacity model, the service scope of the charging station divided by Voronoi diagram, the charging demand in the service area of each charging station and the electric vehicle load forecast and the traffic flow statistics in the service area of, which can get the accurate demand of each charging station. Finally completing the capacity setting of the charging station.
