A method for operating a inverter-based resource connected to a power grid includes receiving one or more voltage feedback signals created by at least one component of the inverter-based resource, wherein distortion components of the one or more voltage feedback signals are more sensitive to voltage distortion created by the inverter-based resource than by external sources of voltage distortion. Further, the method includes extracting a distortion component of the one or more feedback signals having a certain phase sequence and frequency. Moreover, the method includes determining a voltage command for the power converter as a function of, at least, the distortion component. Thus, the method includes controlling the power converter based on the voltage command such that the voltage distortion created by the at least one component of the inverter-based resource is reduced in a manner that is relatively insensitive to voltage distortion created by sources external to the inverter-based resource.
