Sequential Construction Planning of Electric Taxi Charging Station Considering the Development of Charging Demand

Abstract

The charging infrastructure, especially the planning and construction of fast charging stations, is extremely important in the process of electric vehicle (EV) marketization. This paper proposes a method which selects the constructing plan of charging stations with the lowest social costs from the candidate sets of constructing plans. First of all, the optimization model of siting and sizing of charging stations is created and the optimal number and location of the charging station (CS) in the unplanned areas and the optimal charging facility configuration can be obtained by solving the model. After that, the sequential construction strategy is proposed considered two development trends of the charging demand. According to the case results, the sequential construction strategy of charging stations can effectively reduce the growth rate of user's waiting time cost and total social cost and promote the charging facility utilization rate, which helps to avoid the loss of funds and waste of resources.
