Effects of electric vehicles charging on the power system

Abstract

Oil is very important fuel for transportation vehicles, but oil reserves are decreasing in the future. Furthermore, transportation fuel causes greenhouse gas emissions, so renewable energy sources are needed. Using of Electric Vehicles (EVs) offers one solution for this problem. Remarkable reducing of greenhouse gas emissions in the world level require that the majority of all cars should be electric cars. Large-scale charging of different EVs cause problems on power system peak load and charging methods are very important part of solving this problem. Advanced charging technologies such as smart charging could be an interesting method to control EVs charging during hours when electricity is cheaper and/or demand is lowest.
