Claim:
1. A method for operating a wind turbine in a wind farm comprising a multiplicity of wind turbines, the wind turbine electrically coupled to a power-to-gas unit and an electric grid, the method comprising: generating electric power in response to wind rotating a rotor of the wind turbine, wherein electric power starts being generated by the wind turbine when a first wind speed has been reached, wherein the wind turbine is in a partial-load operating mode when the wind speed is between the first wind speed and a second wind speed, and wherein the wind turbine is in a nominal power range when the wind speed is greater than the second wind speed; when the wind turbine is in the nominal power range, providing a first portion of the electric power generated by the wind turbine to the power-to-gas unit that is configured to convert a predetermined proportion of the electric power into a combustible gas and a second portion of the electric power to the electric grid; when the wind turbine is in the partial-load operating mode, providing the electric power generated by the wind power turbine to the electric grid for a predetermined time segment the electric power being provided is constant over time; determining wind forecast data for a predetermined time period that includes a forecasted power value indicative of an estimated power to be generated when the wind turbine is in the nominal power range; and using the wind forecast data to identify the first portion of the electric power to be provided to the power-to-gas unit.
