摘要
电动汽车V2G系统不仅能实现对电池的充放电功能,还能发挥三相电压型PWM变流器的四象限运行功能,为电网提供双向可控的有功功率和无功功率,实现平抑电网负荷波动、削峰填谷等功率调节功能。本文针对V2G系统的并网功率控制,分析了电动汽车V2G系统拓扑结构,并提出基于比例反馈积分(PFI)的功率控制方法,实现V2G系统并网电流指令的精确跟踪;与常规的比例积分(PI)控制进行了对比分析,通过PSIM仿真平台验证了该PFI控制方法的有效性。
V2G system can provide two-way controllable active power and reactive power into the power grid, realize the load fluctuation and stabilize the power grid peak power regulation function. This paper focuses on the power control of the V2G system in the grid-connected mode. The main circuit structure of the V2G system is introduced. To tracking current instructions precisely, the proportion feedback integral control method is proposed. The effectiveness of the proposed control strategy is verified by simulation and experiment results.
