Аннотация:High penetration renewable energies (REs) and large numbers of electric vehicles (EVs) integrated into the grid have brought a great challenges for the grid. The charge and discharge management of EVs to support the grid is the main target of this paper. First, the AC/DC converter, the bidirectional DC/DC converter, the wireless power transfer system and corresponding controller are taken to realize the charge and discharge control of EVs. Second, due to the different service customers, EVs are mainly divided into different categories, their operation rules are analyzed and classified, respectively. Then, a charge and discharge integrated management mode is proposed, the corresponding financial incentive mechanism is proposed to promote the participation of EVs into the grid support activities. Finally, the simulation results are given to illustrate the effectiveness of the proposed method.
