Abstract
A method for controlling an active harmonic filter of an inverter-based resource includes receiving, via a maximum compensation tracker module, a grid feedback signal, determining, via the maximum compensation tracker module, a phase shift signal based, at least in part, on the grid feedback signal, applying, via the maximum compensation tracker module, a phase shift offset signal to the phase shift signal to obtain a modified phase shift signal, determining, via the maximum compensation tracker module, a voltage reference signal for the active harmonic filter based, at least in part, on the grid feedback signal and the modified phase shift signal; and controlling, via the maximum compensation tracker module, the active harmonic filter using the voltage reference signal, wherein the phase shift offset signal ensures that the active harmonic filter injects a current substantially out of phase of a targeted harmonic.
