Abstract
A method for operating a wind turbine for generating electrical energy is provided comprising the steps as described below. The wind turbine comprises a nacelle being rotatably supported on a tower of the wind turbine, in particular wherein at least one tower cable is provided in the tower for electrically connecting the nacelle and/or components thereof to e.g. an electrical installation on a ground of the tower. In one step of the method an early untwist operation for untwisting the tower cables of the wind turbine is initiated at a first specific time. In addition, a future power generation of the wind turbine is predicted for a certain prediction period at least by analyzing a prediction of the wind, in particular by analyzing at least wind direction forecast information and/or wind speed forecast information. The first specific time for initiating the early untwist operation is determined such that an overall predicted energy generation of the wind turbine over the certain prediction period is maximized or that a predicted energy loss caused by an untwist operation is minimized.
