Claim 9:
10. A system for controlling an inverter-based resource connected to an electrical grid, the inverter-based resource having a power converter, the inverter-based resource being part of a power plant having a plurality of inverter-based resources, the power plant being controlled by the supervisory controller, the system comprising:
a supervisory controller;
a local controller communicatively coupled to the supervisory controller, the local controller comprising a power regulator and a voltage regulator, the power regulator configured to perform a plurality of operations, the plurality of operations comprising:
receiving a plurality of power signals;
determining a power error signal as a function of the plurality of power signals;
dynamically determining a dynamic multiplier factor as a function of a number of the plurality of inverter-based resources that are online, wherein the number of the plurality of inverter-based resources that are online is proportional to an effective grid strength seen by the number of the plurality of inverter-based resources that are online;
receiving the dynamic multiplier factor from the supervisory controller;
applying the dynamic multiplier factor to one or more gains of the regulator to determine one or more modified gains;
applying the one or more modified gains to the power error signal to obtain an intermediate power signal; and
generating one or more control commands for the power converter as a function of the intermediate power signal.
