Rule-Based Charging of Plug-in Electric Vehicles (PEVs): Impacts on the Aging Rate of Low-Voltage Transformers

Massive deployment of plug-in electric vehicles (PEVs) in the coming years will create more challenges for the power system including the aging rate of transformers. It will be an essential requirement to propose solutions to minimize the impacts related to the integration of PEVs. Special attention must be given to the residential electric grid where charging will mostly take place. In this paper, first we propose a rule-based (RB) algorithm which determines the minimum charging power levels of home-charged PEVs with/without a charging ban during peak hours. Second, we evaluate the consequences of supplying an RB algorithm on life duration of a low-voltage transformer supplying a residential area.
