Dionysios C. AliprantisPlug-in electric vehicles (PEVs) have been identified as a vital technology to reduce carbon emissions and dependence on petroleum. The emerging fleet of PEVs will introduce a considerable amount of additional load on the power system. We analyze the electric energy and power consumption of light-duty PEVs under uncontrolled and controlled charging scenarios. The analysis is based on information extracted from the 2009 National Household Travel Survey, which collects information on the travel behavior of a national representative sample of U.S. households. For controlled charging, a PEV aggregator that participates in the wholesale electricity market is considered, whose objective is to maximize energy trading-related profits. A minimum-cost load scheduling algorithm is designed, which determines the purchase of energy in the day-ahead market based on the forecast electricity price and PEV power demands. Also, a dynamic dispatch algorithm is developed, used for distributing the purchased energy to PEVs on the operating day. Simulation results are used to evaluate the proposed algorithms, and to demonstrate the potential impact of an aggregated PEV fleet on the power system.


Dionysios C. Aliprantis received the Diploma in electrical and computer engineering from the National Technical University of Athens, Greece, in 1999, and the Ph.D. degree from Purdue University, West Lafayette, IN, in 2003. He is currently a Litton Industries Assistant Professor of Electrical and Computer Engineering at Iowa State University, Ames, IA, USA. He was a recipient of the NSF CAREER award in 2009. He serves as an Associate Editor for the IEEE Power Engineering Letters, and the IEEE Transactions on Energy Conversion. His research interests are related to electromechanical energy conversion, with emphasis on electric machinery (their modeling, simulation, and design), power electronics (particularly machine drives), applications of automatic control to power electronics-based systems, and the analysis of power systems. More recently his work has focused on technologies that enable the integration of renewable energy sources in the electric power system, and the electrification of transportation.
