FIELD: electrical equipment.
SUBSTANCE: invention relates to electrical equipment. According to the method for introducing electric energy into the power supply network through wind turbine (100) or wind farm (112), wind turbine (100) or wind farm (112) converts kinetic energy from wind with variable wind speed into electric energy, depending on the prediction of the wind, predict the wind speed and, depending on the predicted wind speed, the reactive power to be injected is calculated as the predicted reactive power (QP). In this case, the predicted reactive power is predicted for a prediction time interval and by wind turbine (100) or wind farm (112), the predicted reactive power is introduced into the power network later in the prediction time interval, as calculated, even if a wind speed deviating from the predicted wind speed is then set.
EFFECT: increase the stability of the electricity supply network.
