Claim 12:
13. A method for controlling an inverter-based generator to damp power system oscillations, wherein the inverter-based generator is in a plant that is connected to a grid at a point of intersection (POI), the method comprising:
at a local controller configured with the inverter-based generator, generating an auxiliary signal from one or more grid signals having a characteristic indicative of a power system oscillation;
at the local controller, generating a reactive power command signal that is separate from the auxiliary signal and indicates a desired reactive power output from the inverter-based generator; and
at the local controller, using the auxiliary signal to modulate reactive power output from the inverter-based generator from that indicated by the reactive power command signal to improve damping of the power system oscillations.
