摘要
介绍了电动汽车接入电网的概念和作用。采用PSD-BPA潮流及暂态稳定程序对电动汽车接入IEEE30标准系统进行仿真,分析电动汽车分别作为电源和负荷接入电网时对节点电压、系统损耗和系统电压稳定性的影响。仿真结果表明,电动汽车作为电源接入电网时,可有效地提高电网节点电压,降低系统损耗;作为负荷接入电网,会使系统损耗明显增加,而且在电动汽车接入率为100%时,系统电压将进入不稳定状态。
The paper introduces concept and functions of electric automobiles＇ access to the power grid. PSD-BPA flow and transient stability program is adopted to simulate IEEE-30 standard system and impact of electric automobiles＇ access to power grid in cases of serving as power and load on node voltage, system loss and voltage stability of system is analyzed. The simulation demonstrates that node voltage can be improved and system loss can be reduced when electric automobiles have ac- cess to power grid as power; when the electric automobiles have access to power grid as load, the system loss is significantly increased; moreover, when the access rate of electric automobiles is 100 percent, the system voltage may become unstable.
