1. A method for operating at least one inverter-based resource having an asynchronous machine connected to a power grid to provide grid-forming control of the inverter-based resource, the method comprising:
receiving, via a controller, at least one of a frequency reference command or a voltage reference command from an external controller;
determining, via the controller, at least one power reference signal for the inverter-based resource based on at least one of the frequency reference command or the voltage reference command;
generating, via the controller, at least one current vector using the at least one power reference signal;
determining, via the controller, one or more voltage control commands for the inverter-based resource using the at least one current vector by rotating a d-q reference frame of the at least one current vector to an a-b-c reference frame using a phasor angle to obtain the one or more voltage control commands for the inverter-based resource; and
controlling, via the controller, the inverter-based resource based on the one or more voltage control commands that modify at least one of voltage and frequency at a point of interconnection between the inverter-based resource and the power grid in a closed loop manner.
