Two studies are presented quantifying the impact of plug-in hybrid vehicles PHEVs on power systems. The first study quantifies this impact in terms of a primary fuel utilization shifts, b pollution shifts, and c total cost for consumers. The second study quantifies this impact on distribution transformers.In the first study vehicle and power system simulations are used to compute the expected power system fuels utilized to meet a projected level of power demand. The projected electric power demand includes business as usual electric load and random PHEV charging electric load.In the second study the impact on distribution transformers is quantified through a loss of life calculation. The loss of life calculation is based on distribution transformer hot-spot temperature. The hot-spot temperature is estimated using an electro-thermal distribution transformer model and is a function of the transformer currents. The transformer currents are computed using a center-tapped single phase transformer model. Random business as usual and PHEV charging electric loading is assumed.
