Abstract
A method for controlling a wind turbine is disclosed. During full load operation, a power reference value, Pref, representing a power level to be supplied to the power grid by the wind turbine, is received, and the wind turbine is controlled in order to produce an output power which is at or near the power reference value, Pref, while maintaining a constant torque on the generator. In the case that the produced output power of the wind turbine exceeds the power reference value, Pref, excess produced energy is stored in the energy storage system, and in the case that the produced output power of the wind turbine is below the power reference value, Pref, stored energy is retrieved from the energy storage system. A power level being equal to the power reference value, Pref, is supplied to the power grid.
