摘　　要：相比单一结构功能的电动汽车充电站,充放储一体化电站融合了充放电、换电、储能、梯次利用的功能,因此对电站的调度提出了新的要求。文章介绍了充放储一体化电站的结构和功能,包括调度监控系统、充换系统和储能系统。分析了电网、一体化电站和电动汽车之间的信息流,结合一体化电站结构功能提出电站功率调度的核心思想,明确调度参数的定义及参数信息的交互过程,提出相应的调度算法及约束条件。针对我国目前电动汽车主要为公交汽车的特点,结合上海嘉定电网日负荷数据和该地区电动汽车示范园区内充放储一体化电站3个线路公交汽车的实际运营情况,对功率调度算法进行仿真验证,并与其他调度方法进行仿真对比分析,为充放储一体化电站的示范和商业运行提供了参考。Compared to electric vehicles charging station with single structural function, in integrative charging/ discharging and storage station such functions as charging/ discharging, battery-exchanging, energy storage and degrade use are integrated, so new demands on dispatching of electric vehicle station are put forward. The structure and functions of the integrative charging/discharging and storage station are presented, including dispatching and monitoring system, charging/discharging system and energy storage system. The information flows among power grid, integrative station and electric vehicles are analyzed, and combining with the structure and functions of the integrative station the core thought of its power dispatching is proposed to clarify the definition of dispatching parameter and the interaction of parameter information, then corresponding dispatching algorithm and constraint conditions are put forward. Based on the feature that at present electric vehicles are mainly used as omnibuses in China and combined with daily load data of Jiading district power network and actual operating condition of three bus lines subordinate to integrative charging/discharging and storage station located in electric vehicle demonstration park of the district, the proposed power dispatching algorithm is validated by simulation, and the comparative analysis on the obtained simulation results and results from other dispatching methods is performed. Comparative result is available for reference to demonstration operation and commercial operation of integrative chargin~/dischar^in~ and storage station.
