Abstract: Provided is a method for operating a wind turbine having a generator and a rotor with rotor blades. The method includes generating electrical power from wind using the generator, using a first part of the generated power as an auxiliary component for supplying auxiliary devices of the turbine used for operating the turbine, where the auxiliary component varies up to a limit. The method includes feeding a second part of the generated electrical power into a grid as a feed-in component, checking the grid for a grid fault that does not allow feeding power into the grid and continuing the operation of the turbine when the fault is detected. The generation of power from wind is reduced to a cut-back power that corresponds to the limit the auxiliary component for operating the auxiliary devices is used from the cut-back power and remaining residual power of the cut-back power is consumed.

Abstract: A method for feeding electric power into an electric supply network using a wind park having wind power installations is provided. An expected power is determined for a predetermined feed-in period, where the expected power indicates a power value or temporal profile of power expected to be available to the park as power from wind in the predetermined feed-in period. An expected accuracy is determined and is a measure of how accurately the power reaches the expected power in the feed-in period. To determine the expected power, at least one expected wind variable representative of the expected wind speed is determined using a weather forecast, and the expected wind variable is additionally determined or verified, proceeding from the weather forecast, using a correction rule based on local weather data and/or operating data of the park. The expected power is determined on the basis of the expected wind variable.

Abstract: A method for operating a first wind power installation comprising a rotor having a rotor blade that is adjustable with a pitch angle, which generates an electrical power and in the wake of which a second wind power installation is located in at least one wake wind direction, comprising the step of: operating the first wind power installation in a substantially wake-free normal mode with a first pitch characteristic, and operating the first wind power installation in a wake-loaded wake mode with a second pitch characteristic, wherein the first pitch characteristic represents a first profile of the pitch angle and the second pitch characteristic represents a second profile of the pitch angle as a function of the electrical power, wherein the pitch angle of the second pitch characteristic is greater than the pitch angle of the first pitch characteristic for at least one range of the electrical power. The method seeks to maximise the annual energy production of the second wind power installation while complying with constraints, such as compliance with maximum thrust coefficients or wake-influenced turbulence intensities.
