基于V2G的电动汽车无功功率补偿技术
摘要：近年来电动汽车得到了快速发展,非车载充电机等与此匹配的充电设施也大量分布在公共场所。考虑到无功功率对电网的不利影响和V2G(vehicle to grid)技术,研究了电动汽车通过非车载充电机在满足用户充电需求且不损害电池寿命的前提下对电网进行合理的无功补偿。基于瞬时无功理论和解耦控制设计控制环节,对信号做出快速响应。最后在PSCAD/EMTDC的平台上进行仿真,仿真结果表明,电动汽车在充电的同时,可以通过非车载充电机对电网进行合理的无功功率补偿,既可以满足用户的充电需求,又可以调节电网无功功率,充分利用了电动汽车资源,拓展了V2G技术,让V2G技术的实施更加具有可行性。
Abstract:EVs have been greatly developed in the past years. The chargers are widespread in public places now, especially EVs off-board charger.Because of the bad impact of reactive power on power grid, the reactive power compensation using EVs off-board chargers based on V2G(vehicle to grid) is proposed in this paper, which can not only meet the charging requirement, but also compensate the reactive power to power grid, and there aren't bad effects on battery during this operation. Controller which has fast dynamic response to signal is designed based on instantaneous reactive power theory and decoupling control. In the end, the simulation is studied in PSCAD/EMTDC platform. The results show that EVs can compensate reactive power to power grid using off-board chargers, which not only can meet the charging requirement of customers, but also regulate reactive power of power grid. In addition, the proposed method makes good use of EV resource, extends V2G technology, and makes the application of V2G technology feasible.
