Impact analysis of Electric Vehicle charging on distribution system

With the growing penetration of various types of electrical vehicles (EVs) such as Plug-in Hybrid Vehicles/Battery Electric Vehicles (PHEVs/ BEVs), EV charging has the potential to affect the existing distribution system, especially the service lifetime of distribution components. This paper aims at analyzing the potential impact of EV charging on distribution transformers at residential level. Based on the load consumption in East Texas and different assumptions of EV charging scenarios, the impact is demonstrated and compared on monthly basis.
