Abstract: Taking into account the relationship between V2G model and electric vehicle charging station planning, the charging and discharging behavior of electric vehicle users is analyzed on the basis of time-of-use price mechanism. The maximum annual total income of electric vehicle charging station is taken as the objective function while the model of the charging income, discharging cost and inherent cost of the electric vehicle charging station is established. The external selection conditions including environmental conditions, social conditions and policy factors are proposed for the selection of candidate stations. Meanwhile, based on Voronoi diagram, the capacity of electric vehicle charging station is determined by the network traffic flow. The planning of electric vehicle charging station considering V2G model is solved by binary particle swarm optimization. Finally, the case study verifies the effectiveness and feasibility of the proposed planning model.
