Electric Vehicle Impact Studies for Utility Power Systems

Electric vehicle utility impact studies determine the changes in demand and energy needs that increasing penetrations of electric vehicles (EVs) will have on a power system, and these studies identify the changes required in the power system design, equipment, and operation to most effectively accommodate EVs. Two major issues present the greatest challenges to performing these studies. First, only limited information is available on EV demands and market penetration as so few are in use (roughly 40,000 nationwide at the end of 2011). However, the increasing production and sale rates of EVs and the societal trend toward an increasing use of electric transportation requires planning despite these uncertainties. Second, most utility power distribution systems are composed of thousands of circuits and hundreds of thousands of components that could be affected. Quanta Technology’s EVIS method combines two unique but proven analytical techniques to provide an effective way to obtain comprehensive, dependable, but affordable answers.
