Abstract

Due to the characteristics of electric power generation, transmission and distribution in the U.S., experts have identified local distribution as a likely part of the chain to be adversely affected by unregulated PEV (Plug-in Electric Vehicle) charging. This paper presents a study performed to assess the impact of PEV charging on a local residential distribution transformer. Due to the fact that transformer insulation life is mostly affected by the hot-spot temperature, a dynamic thermal model was used for prediction of the transformer hot-spot temperature with the information on power load and ambient temperature, thus the aging of insulation can be predicted. Then, with the results from a Monte Carlo-based mass simulation model for PEV energy consumption, different charging scenarios were conducted to study the impact of PEV charging on transformer insulation life. © 2011 IEEE.
