Abstract
The large-scale development of electric vehicles(EVs)requires numerous charging stations to serve them,and the charging stations should be reasonably laid out and planned according to the charging demand of electric vehicles.Considering the costs of both operators and users,a site selec-tion model for optimal layout planning of charging stations is constructed,and a queuing theory ap-proach is used to determine the charging pile configuration to meet the charging demand in the plan-ning area.To solve the difficulties of particle swarm global optimization search,the improved ran-dom drift particle swarm optimization(IRDPSO)and Voronoi diagram are used to jointly solve for the optimal layout of electric vehicles.The final arithmetic analysis verifies the feasibility and practicali-ty of the model and algorithm,and the results show that the total social cost is minimized when the charging station is 9,the location of the charging station is close to the center of gravity and the lay-out is reasonable.
