A method for feeding electrical energy into an electrical supply grid by means of a wind turbine or wind farm

摘要

The present invention, relates to a wind turbine for feeding electrical energy into an electrical supply grid, and the present invention relates to a wind farm for feeding electrical energy into an electrical supply grid. The invention seeks to improve the support provided to the supply grid by a wind turbine or wind farm. The present invention improves support to the grid by a method for feeding electrical energy into an electrical supply grid by means of a wind turbine (100) or wind farm (112), wherein the wind turbine (100) or wind farm (112) converts kinetic energy from wind with variable wind speed to electrical energy, wherein a wind speed is predicted based on a wind forecast and a reactive power to be fed in is calculated as the predicted reactive power (Qp) based on the predicted wind speed.
