Abstract
This application provides methods and systems for rapid load support for grid frequency transient events. Example electric power systems may include a turbine, a generator coupled to the turbine, where the generator is configured to provide power to an electrical grid, and a controller configured to detect a grid event, determine a rate of change of frequency (rate of change of frequency) value, determine a predicted post-grid event governor set point based on the rate of change of frequency value, and initiate a change to at least one turbine operating parameter based on the predicted post-grid event governor set point.
