1. A method for controlling an inverter-based resource having a power converter connected to an electrical grid, the method comprising:
receiving, via a controller, a first power limit signal for the inverter-based resource from an external controller;
receiving, via a local power constraint module of the controller, a second power limit signal for the inverter-based resource;
determining, via the controller, a constrained power limit signal based on the first and second power limit signals;
applying, via the controller, a first frequency droop function to the constrained power limit signal;
determining, via a maximum power tracking algorithm of the controller, at least one of a power reference signal or a pitch reference signal for the inverter-based resource as a function of an output of the first frequency droop function and the constrained power limit signal;
determining, via the controller, one or more control commands for the inverter-based resource based on at least one of the power reference signal or the pitch reference signal; and
controlling, via the controller, the inverter-based resource based on the one or more control commands so as to support a grid frequency of the electrical grid within power available at the inverter-based resource.
