Claim 10:
11. A converter controller for providing grid-forming control of an inverter-based resource connected to an electrical grid, the converter controller comprising:
at least one controller comprising at least one processor, the at least one processor configured to perform a plurality of operations, the plurality of operations comprising:
receiving a power reference signal;
determining a dynamic power change limit;
determining an upper power boundary and a lower power boundary for grid-induced power deviations from a desired power operating point based, at least in part, on the power reference signal;
determining limits for an inertial power regulator reference based, at least in part, on the upper and lower power boundaries and dynamic power change limit; and
applying the limits to the inertial power regulator reference in an inertial power regulator of the inverter-based resource,
wherein determining 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
estimating the dynamic power change limit based on a comparison of the change in the power component and maximum and minimum power component limits.
