摘　　要：含电动汽车和氢燃料电池汽车的综合能源系统可以实现多能协调互补,有效推动“双碳”目标的实现,但车辆出行计划的临时变动会对系统带来不利影响。为此,提出了包含对车联网(V2G)负荷反馈修正的电热氢综合能源系统多层协调优化策略。基于3层优化的协调配合,电动汽车充放电管理层综合考虑负荷曲线方差和车主不满意度,制定充放电计划并传递给模型预测控制滚动优化层。在滚动优化过程中,实时识别非计划车辆数,自主运行车联网负荷反馈修正层,从而消除车辆出行计划临时改变所带来的不利影响。仿真结果表明,所提策略在实现车主与运营商双赢的同时,提高了系统运行经济性并改善了主网联络线计划值跟踪情况。The integrated energy system including electric vehicles(EVs)and hydrogen fuel cell vehicles(FCVs)can achieve multienergy coordination and complementarity,and effectively promote the realization of the"carbon emission peak and carbon neutrality"goal,but temporary changes in vehicle travel plans have adverse effects on the system.Therefore,a multi-layer coordinated optimal strategy for the electric-thermal-hydrogen integrated energy system including the load feedback correction of the vehicle to grid(V2G)is proposed.Based on the coordination and cooperation of three-layer optimization,the charging and discharging management layer of EVs comprehensively considers the variance of the load curve and the dissatisfaction of EV owners,formulates charging and discharging plans and transmits them to the rolling optimization layer of model predictive control.In the rolling optimization process,the number of unplanned vehicles is identified in real time,and the V2G load feedback correction layer is operated independently,so as to eliminate the adverse effects of temporary changes in vehicle travel plans.The simulation results show that the proposed strategy not only achieves a win-win situation between car owners and operators,but also improves operational economy of the system and improves the track results of the planned power flow of the main grid tie-line line.
