Impact of large-scale electric vehicle application on the power supply

Sufficiency and cost-efficiency of energy supply are essential criteria for the economic development of a country. So far, the energy demand as well as the emission of gaseous pollutants in highly developed countries is significantly determined by the number of cars due to dominating combustion engine vehicles (CV). Since the electric drive as an innovative propulsion system effects neither local tailpipe nor remarkable noise emissions, the electric vehicle (EV) can certainly improve the ecological situation in congested areas all over the world. However, questions of global ecological consequences of large-scale introduction of EVs still have not thoroughly been answered since methods for a combined simulation of EV-traffic and power system operation have not yet been available. This paper represents the results of a comprehensive investigation in order to evaluate different strategies and their consequences for EV operation´s possibilities as well as their effects on power generation and emissions exemplarily for the German power market.
