Planning of Fast Charging Stations Considering Distribution Grid and Transportation Network

Considering both of distribution grid and transportation network, this paper studies the planning of fast charging station. The optimization planning model of charging station is constructed, and the location model is built based on minimizing the average driving cost and the minimum line costs between the charging station and the distribution nodes. The 49-node network and the IEEE 33-node distribution grid are combined together, and the particle swarm optimization algorithm is used to obtain the optimal site of the charging station. The service range of the charging station is determined by the automatic partitioning feature of the Voronoi graph. The optimal planning scheme of 7 charging stations is obtained, and these results verify the validity of the proposed model.
