摘　　要：合理的控制策略可以使电动汽车智能充放储一体化电站在容量充足的情况下为电网提供无功,实现无功的就地补偿。基于电动汽车智能充放储一体化电站的等效电压源运行特性,通过控制算法使其运行于等效发电机或静止无功发生器(SVG)容性模式。研究电动汽车智能充放储一体化电站变流器的无功电压调节特性,进而基于无功电压调控提出了电动汽车智能充放储一体化电站的增值策略和紧急控制策略。实际算例分析表明,电动汽车智能充放储一体化电站具有良好的无功电压控制能力。With the reasonable control strategy and enough capacity,the integrated EV（Electric Vehicle） station of intelligent charging,discharging and storage can be used to locally compensate the reactive power. By a control algorithm based on the operating characteristics of its equivalent voltage source,the integrated EV station operates in the equivalent generator mode or SVG（Static Var Generator） capacitive mode. The reactive power and voltage regulating characteristics of its inverter are studied and the value-added strategy and emergency control strategy are proposed. Analysis of an actual example proves that the integrated EV station has a better performance in the reactive power and voltage control.
