Abstract
A grid frequency rate limiting system for a droop governor is disclosed, the grid frequency rate limiting system including: a rate limit calculator for: obtaining data including at least one of: a transient power response requirement indicator, a turbo-generator power level indicator, a grid stability indicator, a fuel transfer indicator, a combustion mode timing indicator, or a temperature matching indicator; and defining rate limits according to the obtained data; a rate limiter operably connected to the rate limit calculator, the rate limiter for: obtaining a grid frequency reading associated with a grid frequency of an electrical grid; obtaining the defined rate limits; and filtering the grid frequency using the defined rate limits to provide a filtered frequency; and a droop governor operably connected to the grid frequency rate limiting system, the droop governor for: obtaining the filtered frequency; and providing a power response to the electrical grid based upon the filtered frequency.
