Claim Text:
1. A method of controlling a fundamental frequency of a power supply grid operatively connected with a wind turbine facility, the method comprising: producing a predetermined variation of active power at one or more locations within the power supply grid; determining, responsive to producing the predetermined variation of active power, a frequency variation of the power supply grid; updating, based on the determination, a calculation of at least one of a steady-state related coefficient parameter and a dynamic-state related coefficient parameter of the power supply grid, wherein the steady-state related coefficient parameter and the dynamic-state related coefficient parameter each associate the variation of active power with the frequency variation of the power supply grid; determining, using a frequency controller of the wind turbine facility and based on the updated calculation, an amount of active power to provide to the power supply grid corresponding to a desired fundamental frequency of the power supply grid; and controlling, using the frequency controller, the wind turbine facility to provide the determined amount of active power to the power supply grid.
