Sequential construction planning of electric taxi charging stations considering the development of charging demand

Abstract

In the process of electric vehicle marketization, the charging infrastructure, especially the planning and construction of fast charging stations, is extremely important. The construction of charging stations is limited by various social factors and should adapt to the development of the charging demand. Therefore, based on the background research that has considered the social factors and determined a certain number of candidate sites, this paper proposes a method that selects the optimal constructing plan of charging stations with the lowest social costs from the candidate construction plans. First, an optimization model for siting and sizing the charging stations is created and then, the optimal number and location of the charging stations in the unplanned areas and the optimal number and power of in-station charging facilities are obtained by solving the model. After that, two development trends of the charging demand are considered. In case the existing charging stations are not suitable for the changed charging demand, the charging station construction scale is expanded or downsized based on the sequential strategy of the charging station construction, which helps avoid the fund loss and resource waste.
