Mitigating the impact of Charging second generation plug-in battery electric vehicles on distribution transformer's insulation life using TOU prices

Abstract

This paper focuses on investigating the impact of second generation plug-in battery electric vehicles (SGPBEVs) charging on transformer' insulation life. The study considered differed penetrations of SGPBEVs Charging the vehicles (i.e. 0%, 100%, and 200%) and two charging levels (i.e., level 1 and level 2). The time of use (TOU) prices in Ontario Canada are used to mitigate such impact by quantifying the loss of life of transformer's insulation when SGPBEVs are charged at 7PM versus 12 AM respectively.
