  • Patent number: 11552476
    Abstract: 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.
