Cascaded Harmonic Current Control Loop for VSG Harmonic Current Suppression

2023 4th International Conference on Power Engineering (ICPE), 2023
When a Virtual Synchronous Generator (VSG) is connected to a distorted grid, its output current quality is hard to be guaranteed. The existing harmonic control schemes based on PCC voltage sampling, are limited by the small line impedance.
