Optimization of power flow and scheduling for EV charging based on distributed control

This paper deals with electric vehicle(EV) charging problem in a distributed method. EV is getting more attention from the environmental view point. For example, it can reduce oil consumption and emission of greenhouse gas. However EV needs much electric power for one charge, so electric power demand is forcasted to increase dramatically. And considered from the grid side, if power demand increases, voltage drop in the grid will be caused.So this paper proposes effective charging strategy for both each EV and gridside based on distributed control. The charging strategy we propose is minimizing base load generator cost and voltage drop at the same time to avoid concentration of the power use in a peak hour. At the last of this paper, the superiority of our method is demonstrated in simulations by using IEEE 15-bus system and describe about the future works.
