Due to the characteristics of electric power generation, transmission and distribution in the U.S., experts have identified the local distribution network as a likely area to be adversely affected by unregulated PEV (Plug-in Electric Vehicle/Electric Vehicle) charging. This paper presents a study performed to assess the impact of PEV charging on a local distribution transformer. Due to the fact that transformer insulation life is mostly affected by the hot-spot winding temperature, a dynamic thermal model was used for prediction of the transformer hot-spot temperature with the information of 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 analysis, different charging scenarios were conducted to study the impact of PEV charging on transformer insulation life.

Abstract
Due to the characteristics of electric power generation, transmission and distribution in the U.S., experts have identified the local distribution network as a likely area to be adversely affected by unregulated PEV (Plug-in Electric Vehicle/Electric Vehicle) charging. This paper presents a study performed to assess the impact of PEV charging on a local distribution transformer. Due to the fact that transformer insulation life is mostly affected by the hot-spot winding temperature, a dynamic thermal model was used for prediction of the transformer hot-spot temperature with the information of 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 analysis, different charging scenarios were conducted to study the impact of PEV charging on transformer insulation life.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
