| 摘要: |
| 针对大量电动汽车集中充电引起的电网电能质量下降、路网道路拥堵和充电站内充电桩未能充分利用的问题，结合路网、充电站和配电网的实时运行状态，提出一种基于第三代前景理论的充电引导策略。分别对路网、充电站和电网建立不同的运行状态描述模型；基于第三代前景理论，根据充电桩和电动汽车时空状态建立动态多参考点，根据“车-路-网”系统的运行状态对用户充电选择进行前景分析，通过前景值建立耦合系统状态模型，并将最大前景值方案作为推荐引导策略方案。仿真结果表明，所提充电引导策略不但能够充分协调分配充电负荷以及合理缓解交通压力，而且能够有效保证配电网电压处于正常的运行范围内。 |

| Abstract: |
| Aiming at the problems of power quality decline, road network congestion and insufficient utilization of charging piles in the charging station caused by the centralized charging of a large number of EVs(Electric Vehicles),a charging guiding strategy is proposed based on the third-generation prospect theory, which combines the real-time operation states of road network, charging station and distribution network. Different operation state description models are respectively established for road network, charging station and power grid. On the basis of the third-generation prospect theory, the dynamic multiple reference points are established according to the temporal and spatial states of charging station and EVs, the prospect of user charging selection is analyzed according to the operation state of “EVs-road-network” system, the state model of the coupling system is built according to the prospect value, and the scheme with maximum prospect value is taken as the recommendation guidance strategy scheme. The simulative results show that the proposed charging guidance strategy can not only fully coordinate the allocation of charging load and rationally relief the traffic jam, but also effectively ensure the voltage of distribution network in common operation range. |
