摘　　要：考虑到智能电网中电动汽车充电过程中损耗、谐波、故障等因素,给供电系统带来了安全隐患,影响了用户使用。因此,提出基于契约理论的能量定价机制策略,激励用户购买电能,提高能量利用率。文章结合移动充电站和电动汽车用户之间的交易供求关系,构建了两者各自的效用函数;基于契约理论研究和设计最优的供电条款策略来最大化自身利益,获得最优解;并通过仿真结果证明了提出方法的有效性。Considering factors such as losses,harmonics,and faults during the charging process of electric vehicles in the smart grid,which pose safety hazards to the power supply system and affect user usage.Therefore,an energy pricing mechanism strategy based on contract theory is proposed.Firstly,based on the transaction supply and demand relationship between Mobile Charging Station(MCS)and electric vehicle users,we construct their respective utility functions;Secondly,the optimal power supply clause strategy is studied and designed based on contract theory to maximize their own interests,and the optimal solution is achieved;Finally,the effectiveness of the proposed method is demonstrated through simulation results.
