Sizing and Locating Planning of EV Centralized-Battery-Charging-Station Considering Battery Logistics System

This article investigates the optimal planning of centralized charging and multipoint distribution network that includes centralized battery charging stations (CBCSs) and battery distribution stations (BDSs), which considers the battery logistics system. Based on the analysis of the characteristics of travel chains of swapping electric vehicles (SEVs), a time-space load forecasting model of SEVs is proposed. Then, based on function and characteristic analysis, operation models of CBCS, BDS, and the battery logistics system are built. Afterward, the sizing models of CBCSs and BDSs are established. Then, a double-level planning model of CBCSs considering battery logistics system is proposed. In the first level planning, the sizes and locations of CBCSs and BDSs are planned, and in the second-level planning, the economy of battery logistics company is optimized. Finally, the CPLEX toolbox and the Bellman-Ford algorithm are used to solve the planning model. Taking the actual situation of a certain region as the planning area, the feasibility and effectiveness of the method proposed in this article are verified.
