PEV demand flexibility and its impact on the electric power system

Transportation is one of the major consumer of energy in US and around the world. According to the latest Department of Energy (DOE) Transportation Data Book [1], 27.8% of total US energy consumption is attributed to transportation. Of this amount, 58.9% is consumed by cars and light duty trucks to make up 16.4% of total energy consumed by Americans. To put this in perspective, according to DOE energy usage estimates [2] 39.2% of energy consumed in US is spent for electricity generation.
