One million plug-in electric vehicles on the road by 2015

Abstract

It is mentioned that one million plug-in hybrid and electric vehicles will be on the road by 2015 in United States to reduce emission. If one million electric vehicles (EVs) are connected to the existing electric grid randomly, peak load will be very high. Electrified transportation based on a traditional thermal power system will be costly economically and environmentally though it has a great value for electric power and transportation sectors. EVs cannot alone solve the emission problem completely since they need electric power, which is one of the main sources of emission. Therefore, significant emission reduction greatly depends on the maximum utilization of renewable energy. Two models are investigated to show the effect of one million EVs on electric power and transportation sectors. Linear and non-linear systems are used in modeling the emissions generated from the transportation and electric energy sectors respectively.
