Electric vehicles (PEV, eCAR, etc.) continue to become more popular as environmental concerns increase. They are a significant means to reduce reliance on fossil fuels and emission of greenhouse gases (GHG). They will be a major factor in load growth with a potential to eventually consume 600 TWh/year. This estimate assumes 30 kwh for a 100-mile trip [16], and 10 000 miles per year for 200 million vehicles in the United States. From a purely reliability viewpoint, electric vehicles have features similar to both demand response and storage re- sources. However, as a significant factor of load growth, PEVs can aggravate demand variability and associated reliability problems depending on the charging schemes and consumer behavioral patterns. Long recharge times lead to unacceptable vehicle unavailability and short recharge times have potential to increase congestion at the distribution level.
