电动公交车换电站负荷仿真与预测

摘要

电动公交车正在国内大规模推广,与之配套的换电站也处在大规模建设阶段.电动公交车换电站是一种新型的电力负荷,它影响该区域的电力设备安全稳定运行.由于电动公交车不同于普通的公交系统,其能量补给的特点导致其公交调度、补给方式、运行模式均有自己的特点.本文研究了换电站的换电方式,基于电动公交车的运行特点提出了运营流程仿真方法,结合充电机的充电特性曲线,利用MATLAB软件实现了换电站的供电负荷仿真与预测,为电动公交车换电站的设计和建设提供参考.%With the rapid rising of the number of electric bus, the battery swap stations are also at the stage of rapidly building. Battery swap station is a new type of power load, it affects the safe and stable operation of power equipment in the area. The electric bus is different from the common bus, because of their different energy source, they have different bus scheduling, supply mode and operation mode. This article studies the operation in swap station first, a method and simulation software is proposed, which is based on the feature of electric bus. Combining with charging curve and using MATLAB software, it completes the load simulation and forecasting to provide reference for electric bus battery swap station construction.
