摘要: 电动汽车充换储一体站是集充电站、换电站和梯级储能电站于一体的电动汽车(electric vehicle ,EV)集中型综合供储能电站,可以发挥充电站和换电站的可调度潜力,并能够减小功率波动。提出了一种新型电动汽车充换储一体站模型,该模型综合考虑了电动汽车快充站、换电站和梯级储能电站。首先,基于快充用户的行驶行为特点,建立了电动汽车快充站模型;其次,根据城市道路速度流量实用模型,建立了电动汽车换电站模型;最后,结合梯级储能模型,构建了集成的电动汽车充换储一体站模型。以某地区公交线路实际道路情况为仿真算例,验证了提出的一体站模型能够满足电动汽车充电负荷的需求,且具有降低运维成本和抑制功率波动的优势。

Abstract: The electric vehicle (EV) charging-swapping-storage integrated station (CSSIS) is an electric vehicle centralized integrated energy storage and power station that integrates charging stations, power conversion stations and cascade energy storage power stations, which can reduce system power fluctuations. This paper proposes a model of electric vehicle CSSIS considering fast charging station, battery swapping station and cascade energy storage station. Firstly, according to the behavior characteristics of fast-charging users, a model of EV fast charging station is established. Secondly, on the basis of speed-flow practical model of city roads, a model of EV battery swapping station is established. Finally, combined with the cascade energy storage model, an integrated electric vehicle CSSIS model is constructed. Taking the actual road conditions of bus lines in a city into account, a case verifies that the integrated station model proposed in this paper can meet the demand of electric vehicle charging load, and has the advantages of reducing the daily total operation cost and suppressing power fluctuation.

Key words: electric vehicle charging-swapping-storage integrated station, fast-charging users, speed-flow model, actual road condition
