Abstract:With the increasing number of Electric Vehicles (EVs), the out-of-order random charging behaviors cause the smart grid overloaded and the battery depreciation. Though a great deal of works focusing on EV charging coordination are proposed, it still remains unexplored to coordinate the EV charging by maximizing the convenience of EV drivers and minimizing the battery depreciation. This is a vital problem for increasing the service quality of the charging station and the users' satisfaction, since the convenience and lifetime of battery are specially concerned by EV drivers. In this paper, we systematically study the problem and a real-time charging scheme is proposed to coordinate the electric vehicle (EV) charging and decrease the battery depreciation to the battery. To prevent private leak and decrease calculation complexity, a ADMM-based distributed method is proposed in our paper. Extensive evaluations show that our distributed optimization method brings significant cost savings over existing methods. Simulation results show that our proposed algorithm could reduce the price cost of EV drivers and battery lifetime depreciation by up to 18.3% and 33.0%.
