The optimal EV charging/discharging strategy in smart grid from a perspective of sharing-economy

There has been a desirable trend in recent years towards Electric Vehicles (EVs) contributing less air pollution and noise pollution than internal combustion engine vehicle. EV charging/discharging problem brings a new challenge to the power operation and control. In this paper, the charging/discharging problem is modelled by noncooperative game theory, the payoff function of this model not only maximizes the revenue of discharging activity, but also minimizes overall generation cost by decreasing electricity price on peak hours. The result of simulation illustrates that charging behaviors can shift the charging demand from peak hours to off-peak hours, while discharging behaviors can shave the peak loads in the parking periods.
