Investigation of plug-in hybrid EVs (PHEVs) and their effects on power distribution systems in the NE and SW united states: Summary of a panel session presentation

This paper will focus on showing the projected effects of PHEVs on residential loads in the Northeast and Southwest U.S. The Southwest studies, based in New Mexico, include consideration of central air conditioning (A/C) as a major load. The Northeast studies, based in Massachusetts, examine winter as well as summer load profiles with approximately the same PHEV charging requirements. Since truly commercial PHEVS are not expected to be available until late 2010, we have studied the literature and projections from manufacturers and others working in the PHEV to estimate battery capacities and charging power requirements. We have assumed 9-10 kWh per charge over periods of 5 hours. If a 7.0 kW PV system (ac rating) is employed in NM, this energy resource will provide most of the energy required for home use as well as charging two PHEVs. Additional information will be provided in the presentation.
