Grid-tied inverters require a phase-locked-loop (PLL) to detect the grid frequency and phase for synchronization. Grid voltage harmonics can distort the PLL phase signal, which consequently disturb the reference waveforms used by the inverter current controller and modulator. Distortion characteriza...
