基于多采样电网侧电流控制的LCL滤波并网变流器耗散性鲁棒性增强

Capacitor current active damping is a common method to achieve dissipation for LCL-filtered grid-connected converters using grid-side current control. However, the dissipative characteristic of converter output admittance near the critical frequency can easily be jeopardized by the filter parameter deviation. Besides, the grid voltage feedforward is often overlooked when designing dissipativity, w...
