Abstract: While there are a number of useful studies on the greenhouse gas impacts of transportation electrification, only recently have researchers begun to understand the impacts of electricity on electric power infrastructure. Thus, the primary goals of this research project were to understand these impacts in detail and to develop new methods for reducing the impact of transportation electrification on the electricity transmission and distribution infrastructure. In particular, this report focuses on understanding and mitigating the impact of transportation electrification on the medium and low voltage distribution infrastructure, through which electricity is transported from the bulk power grid, through neighborhoods, to individual homes and businesses. This project focused specifically on the impacts of electric vehicles on two key components of power distribution systems: residential service transformers, and underground cables. This project also studied new methods to dynamically adjust the number of electric vehicles that are charging simultaneously, in order to mitigate the risk of electricity infrastructure damage from electric vehicle charging.
