Abstract: Provided is a method for operating an electrical storage station on an electrical supply network. The network has electrical consumers, the storage station, and at least one wind power installation to generate electrical power from wind. The method includes generating electrical power by way of the installation as generated wind power, and feeding a feed-in power into the network. The electrical feed-in power at least results from the generated wind power and a storage power taken up or output by the storage station. The feeding of the feed-in power into the network is controlled depending on a station state of charge and a wind and/or power forecast. Changes in the feed-in power over time are controlled depending on the wind and/or power forecast and a limit gradient is specified to limit the changes in the feed-in power thereto. The limit gradient is specified depending on the wind and/or power forecast.

Abstract: Provided is a method for detecting low-frequency oscillations, in particular subsynchronous resonance, in an electrical supply grid, wherein the electrical supply grid has a grid voltage at a grid nominal frequency, comprising the steps of capturing at least one electrical signal from the electrical supply grid, and evaluating the electrical signal by means of wavelet analysis, during which a time-dependent frequency pattern is created by analyzing a correlation of the captured signal with a predetermined wavelet mother function, wherein the presence of a low-frequency oscillation is assumed if at least one further low-frequency frequency component is present in the time-dependent frequency pattern in addition to a fundamental component.

Abstract: A method for providing data sets for the units, in particular wind turbines, of a wind park. The wind park is divided into at least two groups, wherein at least one group, a plurality of groups or all groups in each case have at least two units. An individual data set is first generated in each case for each of the groups. A data packet which comprises at least the generated individual data sets is then generated and the data packet is then transmitted to all units of the wind park. A wind park controller, a method for receiving a data set, a unit and a wind park is also provided.

Abstract: A method for detecting low-frequency oscillations, in particular subsynchronous resonances, in an electrical supply grid is provided. The grid has a line voltage with a rated line frequency. The method comprises recording first and second series of measurements each for performing a frequency analysis (FFT). The method includes performing a lower frequency analysis for the first series for a lower frequency range and forming a lower amplitude spectrum. The method includes performing an upper frequency analysis for the second series for an upper frequency range and forming an upper amplitude spectrum. The method includes testing whether a low-frequency oscillation component can be identified in the lower amplitude spectrum, and testing whether a low-frequency oscillation component can be identified in the upper amplitude spectrum, where the presence of a low-frequency oscillation is assumed when a low-frequency oscillation component is identified in at least one of the lower and upper amplitude spectra.

Abstract: A rotor blade of a wind turbine, to an associated wind turbine, to an associated wind farm and to associated methods. The rotor blade has a leading edge and a trailing edge and extends in a longitudinal direction of the rotor blade between a root end and a tip end, wherein a direct connection between the leading edge and the trailing edge is referred to as a chord line, wherein the rotor blade has serrations in the region of the trailing edge at least in some section or sections, wherein each of the serrations has a base line, which is arranged at the trailing edge, and an end point, which is furthest away from the base line, which together span a plane of the serration, wherein an angle between the plane of at least one of the serrations and the profile chord of the rotor blade is formed as a function of at least one environmental parameter at the installation location of the wind turbine.
