Research on Layout Planning of Electric Vehicle Charging Stations Based on Weighted Voronoi Diagram

With the increasing popularity of electric vehicles, the reasonable layout of charging stations has become particularly important. This article proposes a method for predicting the layout of public charging stations based on weighted Voronoi diagrams. By weighting the candidate points of charging stations and aiming to minimize the charging distance of users, combined with the actual situation of the case city and expert opinions, reasonable weight allocation is carried out for various influencing factors such as traffic flow and land use properties. The weighted Voronoi diagram is used for spatial division to ensure that the service range of each charging station is reasonable and the overlap is minimized, and the layout of charging stations is scientifically planned. Through case analysis, the effectiveness of this method in the layout planning of public charging stations in H city was verified. A total of 80 charging stations were planned, including the use of existing charging stations, parking lots, and regulated parking lots. This method provides a scientific basis for optimizing the layout of urban charging stations, which helps to improve the convenience of electric vehicle charging and the overall efficiency of urban charging facilities.
