Abstract

Hybrid electric vehicles with the capacity of being recharged from the grid may provide a significant decrease in oil consumption. These plug-in hybrids (PHEVs) will affect utility operations, adding additinoal electricity demand. Because many individual vehicles may be charged in the extended overnight period, and because the cost of wireless communication has decreased, there is a unique opportunity for utilities to directly control the charging of these vehicles at the precise times when normal electricity demand is at a minimum. This report evaluates the effects of optimal PHEV charging, under the assumption that utilities will indirectly or directly control when charging takes place, providing consumers with the absolute lowest cost of driving energy.
