A method for providing grid-forming control of an inverter-based resource includes monitoring the electrical grid for one or more grid events. The method also includes controlling, via a power regulator of a controller, an active power of the inverter-based resource based on whether the one or more grid events is indicative of a severe grid event. In particular, when the one or more grid events are below a severe grid event threshold, thereby indicating the one or more grid events is not a severe grid event, the method includes controlling, via the power regulator, the active power according to a normal operating mode. Further, when the one or more grid events exceed the severe grid event threshold, thereby indicating the one or more grid events is a severe grid event, the method includes controlling, via the power regulator, the active power according to a modified operating mode. Moreover, the modified operating mode includes temporarily re-configuring the power regulator to reduce or eliminate power overloads induced by the severe grid event for as long as the one or more grid events exceed the severe grid event threshold.

A method for controlling an inverter-based resource (IBR) connected to an electrical grid includes receiving grid parameter(s) and applying a droop function to the grid parameter(s) to determine a power droop signal. Further, the method includes receiving a power reference signal. Moreover, the method includes determining a power command signal as a function of the power droop signal and the power reference signal to allow for a fast response in a power output of the IBR to the grid parameter(s). The method also includes applying power constraint(s) to the power command signal to limit how much the power output of the IBR can be changed due to the grid parameter(s). Further, the method includes determining one or more control commands for the IBR based, at least in part, on the power command signal. Thus, the method includes controlling the IBR based, at least in part, on the power command signal.
