摘要
针对电动汽车的充电行为将影响和改变系统的负荷特性，对电网发展产生影响的问题，分析了不同类型电动汽车的充电行为，重点研究了即插即充、夜间充电、智能充电等充电模式对广东电网负荷特性的影响，定量模拟计算结果表明，合理利用电动汽车充电负荷和储能特性将有助于降低电网最大负荷和峰谷差，提高电网的利用效率。
The electric vehicle （EV） industry is developing rapidly, and will bring new opportunities and challenges to the power grid. With large scale development, the EV＇s total charging behavior will change the load characteristics of power grid, and impact on the development of the power grid. In this paper, preliminary charging behaviors are analyzed for different types of EVs firstly, and then the impact to the load characteristics of Guangdong Power Grid are studied and simulated quantitatively; with different energy supply modes considered, such as plug charger, night charger, smart charger. The results show that the power grid could reduce the peak load and peak power difference obviously with the help of EV＇s charging load and energy storage characteristics.
