Abstract
Electric vehicles (EVs) are recognized as a promising remedy for the environmental crisis and fuel shortage faced by modern metropolises. But meanwhile, with the popularization of EVs, the unordered charging of EVs will have negative impacts on both the power distribution network (DN) and the traffic network (TN). The well-scheduled EV charging/discharging behaviors could participate in the coordinated operation of TN and DN to significantly enhance the energy utilization efficiency of both networks. With an assumption that an entity like state grid capable of dispatching distributed generators and adjusting the charging prices of fast charging stations, a traffic-distribution coordination (TDC) model is proposed to minimize the travel cost of TN and the energy service cost of DN, which simultaneously considers the economic operation of DN by alternating current dynamic optimal power flow and the traffic flow assignment of TN by EVs dynamic user equilibrium, respectively. And afterward, the augmented Lagrangian alternating direction inexact Newton method is adopted to solve the TDC model. Finally, the necessity of the coordinated operation of TN and DN and the effectiveness of the TDC model are validated in an integrated system of modified Nguyen-Dupius TN and IEEE 33-bus DN.
