摘　　要：无功补偿是改善电能质量、促进电网经济高效运行的最有效措施之一,考虑到智能电网环境下V2G(vehicle togrid)技术应用的可能性,提出了基于V2G的无功功率补偿技术;并针对已有V2G电路的结构特点,结合瞬时无功功率理论和无差拍控制原理,分析了所建模型瞬时无功的检测和补偿控制,最后通过仿真和实验验证了该方案的可行性;结果表明,借助于V2G技术,将电动汽车作为无功功率补偿装置能较好地实现家庭负荷无功就地补偿。Reactive power compensation is one of the most effective measures to improve power quality and promote economic and efficient operation of power grid.Considering the possibility of applying vehicle to grid（V2G） technique in smart-grid environment,a V2G-based reactive power compensation technology is proposed.Based on structural features of existing V2G circuits and combining instantaneous reactive power theory with the principle of deadbeat control,the detection of instantaneous reactive power in the proposed model and the control of the compensation are analyzed.Finally,the feasibility of the proposed scheme is verified by both simulation and experiments.Verification results show that by means of V2G technique,the household load can be locally compensated by electrical vehicle（EV） used as reactive power compensator.
