A system and method of operating a wind farm, having multiple wind turbine generators, at high wind speeds is provided. Wind speeds at individual wind turbine generators are monitored and a signal is transmitted from the wind turbine generators to a wind farm control system based on the monitored wind speeds. Rate of change of collective power output of the wind farm is temporally monitored and is controlled by coordinating of operational states of the wind turbine generators based upon the signals transmitted by the one or more wind turbine generators, operating conditions of the wind turbine generators and the monitored rate of change of power output of the wind farm.
