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.

Method and wind park for feeding electric power into an electric supply network

The invention relates to a controller for a wind turbine with an operating software for operating the wind turbine, wherein the operating software is set up to regulate or control at least an electrical output of a wind turbine generator, a speed of a wind turbine rotor, an azimuth angle of a wind turbine nacelle, and a pitch angle of at least one rotor blade of the wind turbine rotor, wherein the operating software comprises a core module and at least one customer application. The customer application is set up to determine a parameter, in particular a control variable, in particular a target value, depending on at least one function of the customer application, and provide it for the core module. The core module is set up to detect and/or predict a load acting on the wind turbine during an operation of the wind turbine, and in a case where a detected or predicted load lies below a predefined load limit, to operate the wind turbine as a function of the parameter provided by the customer application, and in a case where a detected or predicted load exceeds the predefined load limit, to adjust the prepared parameter and leave the wind turbine unconsidered as a function of the adjusted parameter or the provided parameter, and operate the wind turbine with a parameter determined in the core module. The controller further has a first programming interface and a second programming interface, wherein the first programming interface is set up to program the core module, in particular the load limits, and wherein the second programming interface is set up to program the customer applications, in particular their function, and prevent the core module from being reprogrammed via the second programming interface. The invention further relates to a method for a controller and a computer program product.

Controller and method for a wind turbine as well as computer program

A method of operating at least one wind turbine including: receiving a first signal which is indicative of a level of a remuneration for electrical energy, which is fed currently and/or in the future into a grid to which the wind turbine is connected, producing a control signal dependent on the first signal, and controlling the wind turbine with the control signal for generating power of the wind turbine, that is dependent on the control signal. A wind turbine and a central control for carrying out such a method and a system comprising a central control and a plurality of wind turbines.

Method of operating at least one wind turbine, and device therefor

Provided is a method of feeding electric reactive power using a wind farm comprising wind turbines. The wind farm feeds a wind farm active power output and the wind farm active power output includes individual plant active power outputs each generated by one of the wind turbines. The wind farm feeds a wind farm reactive power output into the electrical supply network and the wind farm reactive power output includes individual plant reactive power outputs each generated by one of the wind turbines. The method includes determining a total wind farm reactive power output to be fed in by the wind farm and calculating, for each wind turbine, an individual plant reactive power output to be generated. The individual plant reactive power output is determined depending on the individual plant active power output and depending on the wind farm reactive power output to be fed in.

Method of controlling a wind farm

A method for feeding electrical power into an electrical supply network by means of at least one wind power installation having a power control and a generator, comprising the steps of: creating an electrical power gradient for an electrical power to be generated by the wind power installation wherein the power gradient at least: is limited by means of a stabilization operator or is created by means of a prediction operator in such a way that the electrical power gradient is unequal to a predicted wind power gradient, adjusting the created electrical power gradient in the power control of the wind power installation, generating an electrical power by means of the wind power installation depending on the created electrical power gradient for a feed-in time period with a feed-in time.
