| 电动出租车作为快速充电及路-电耦合网络的主要参与者，其连续行驶-充电行为严重影响了路-电耦合网络的运行状态，为此提出了基于路-电耦合网络的电动出租车快速充电引导及其定价策略。首先，提出了电动出租车在路-电耦合网络下交通流-能量流-信息流的交互框架；然后，提出了交通网的信息动态更新策略，建立了单辆电动出租车模型用于模拟电动出租车的连续行驶-充电状态切换行为；在此基础上，提出了路径规划与交通网信息更新同周期的动态导航及考虑下一寻客点的选站决策方法；最后，根据站内负荷和选站负荷进行虚拟负荷预测，提出了基于虚拟负荷和利用率均衡的充电站定价策略。算例仿真结果表明，所提方法能够均衡充电站负荷，缓解交通网的拥堵状况，提高电动出租车的运营收入。 |

| Abstract: |
| As the main participants of fast charging and traffic-grid coupling network, the continuous driving-charging behavior of electric taxis seriously affects the operation state of traffic-grid coupling network. Therefore, the fast charging guidance and pricing strategy of electric taxis based on dynamic traffic-gird coupling network are proposed. Firstly, an interactive framework of traffic flow-energy flow-information flow for electric taxis in traffic-grid coupling network is proposed. Then, the dynamic updating strategy of traffic network information is proposed, and the model of a single electric taxi is built to simulate the continuous driving-charging state switching behavior of electric taxis. On this basis, the dynamic navigation of route planning and traffic network information updating in the same cycle and the station selection decision method considering the next passenger seeking point are proposed. Finally, the virtual load is predicted according to the station load and station selection load, and the pricing strategy of charging station based on virtual load and utilization ratio balance is proposed. The simulative results show that the proposed method can balance the load of charging station, alleviate traffic congestion and increase the operation income of electric taxis. |
