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.

Method for operating a wind power installation, controller for operating a wind power installation, and wind farm

Provided is a method for optimizing an operation of a wind farm. The farm includes wind turbines and each can be adjusted via operating settings, and a farm model depicting the wind farm or part thereof is used. The method comprises an optimization sequence using the farm model, with the steps: specifying an optimization wind direction in the farm model for optimizing the operation of the farm for this wind direction; varying operating settings of at least a first leading turbine of the farm model; determining effects of varying the operating settings of the first leading turbine on at least one downstream turbine of the farm model, which is aerodynamically influenced by the first leading turbine, by means of a wake model; determining a total farm result of the farm model; wherein the operating settings are varied so as to optimize the total farm result.
