摘　　要：为实现城市交通电力耦合系统在城市道路、充电设施、输电线路阻塞环境下的优化运行,提出了计及多重阻塞的动态交通电力流联合优化方法.首先,基于时空网络模型,提出了计及电动汽车移动、静止、充电、排队模式的队列时空网络模型,构建了适用于电动汽车的车辆调度模型,进而形成动态交通分配模型,以减少交通出行损失.其次,通过优化发电机组、储能等的出力和备用计划,计及城市电网安全、备用约束,构建了安全约束动态经济调度模型,以降低碳排放及发电成本.随后,形成多目标动态优化模型,并将其转换为混合整数凸二次规划问题.最后,在耦合IEEE-30、Sioux Falls系统中验证了所提模型的有效性.To realize the optimal operation of urban coupled transportation power systems underthe road,charging facilities,and transmission line congestions,a dynamic optimal traffic power flow(DOTPF)model was formulated under congestions.Based on the time space network(TSN)approach,a novel TSN with queues was proposed,considering the moving,parking,charging,and queueing state transitions.A vehicle routing problem was formulated for electric vehicles(EVs)and further incorporated into the dynamic traffic assignment problem(DTAP),reducing the traffic demand losses.With security and reserve constraints,a dynamic security-constrained carbon dioxide-oriented optimal power flow(OPF)problem was formulated to reduce the carbon emission and generation cost,by optimizing the scheduling of thermal units and energy storage systems.A multi-objective DOTPF problem was formulated,and further reformulated into a convex mixed-integer quadratic programming problem.The effectiveness of the proposed DOTPF was verified based on the simulation results on coupled IEEE-30 and Sioux Falls system.
