Claim 0:
1. A method for providing grid-forming control of an inverter-based resource connected to an electrical grid, the method comprising:
receiving, via a controller, a power reference signal;
determining, via the controller, an upper power boundary and a lower power boundary based on the power reference signal;
determining, via the controller, a dynamic power change limit for grid-induced power deviations from a desired power operating point;
determining, via the controller, limits for an inertial power regulator reference based, at least in part, on the upper and lower power boundaries and the dynamic power change limit; and
applying, via the controller, the limits to the inertial power regulator reference in an inertial power regulator of the inverter-based resource,
wherein determining, via the controller, the dynamic power change limit further comprises:
estimating a change in a power component of the inverter-based resource as a function of one or more grid feedbacks, the power component associated with at least one of a grid phase jump or a grid frequency drift; and
determining the dynamic power change limit based on a comparison of the change in the power component and maximum and minimum power component limits.
