Claim 0:
1. A method for operating a wind turbine, wherein the wind turbine includes a rotor with rotor blades and a power conversion system mechanically connected with the rotor, the power conversion system configured to convert input motive power into electrical output power and electrically connected to a network for feeding the electrical output power to the network, the method comprising:
determining a current frequency (f) of the network; and
when the current frequency (f) is equal to or lower than a threshold frequency (fthresh), operating the power conversion system to increase an electrical output power (P) by an output power increase (PI) in accordance with a monotonic function (PI(f)) of the current frequency (f), the monotonic function (PI(f)) being limited to a maximum output power increase value (PImax) determined as a function of an initial electrical output power (P0) of the power conversion system.
