A system and method operate a renewable energy source having an inverter-based resource (IBR) system and controlled by a power converter controller. The IBR system is operated in grid-forming mode (GFM) control. The power converter controller receives a control signal that is derived based on a frequency droop function performed on a detected grid frequency at an upstream controller. The power converter controller generates an output power actuator signal based on a frequency droop function performed on the detected grid frequency at the power converter controller. A first compensation is applied to the upstream controller that reduces or eliminates changes in the control signal received by the power converter controller due to changes in the grid frequency.
