Abstract

With the large number of electric vehicles (EV) in charging stations, the power system will face a large amount of charging demand. It can lead to voltage instability and higher power loss in the electricity distribution network. However, by constructing EV charging parking lots in suitable places and managing them optimally, we can benefit from the advantage of using the battery capacity of EVs. This article proposes a mixed-integer linear programming model for locating and sizing electric vehicle parking lots (EVPL) to maximize the profit of the EVPL owner, taking into account the network constraints and the voltage stability index (VSI). Moreover, the impact of different travel patterns for EVs on working days and weekends has also been investigated. The desired model has been implemented in a distribution system with 37 buses, which includes four different areas regarding the type of travel. The results show that the VSI drops in the presence of EVPLs. However, it can be constrained through optimal location and management of EVPLs.
