Реферат: A method for transitioning the operation of a wind turbine into an energy harvesting mode in which the wind turbine (100) operates to generate electrical power from wind energy is provided. An energy storage system (50) associated with the wind turbine (100) is configured to supply electrical power to an auxiliary system (10) of the wind turbine when the wind turbine is not generating or receiving electrical power sufficient for supplying the auxiliary system (10). The method comprises operating the wind turbine (100) in a first operating mode (72) in which an electrical power supply to a first group (11) of one or more auxiliary power consumers (12, 13, 14) of the auxiliary system (10) is ceased; obtaining environmental data including at least one of wind data and meteorological data; and determining if the obtained environmental data meets a predefined condition. If the predefined condition is met, a transition of the operation of the wind turbine (100) into the energy harvesting mode (74) is caused, wherein transitioning the operation into the energy harvesting mode (74) comprises supplying electrical power from the energy storage system (50) to the one or more auxiliary power consumers (12, 13, 14) of the first group (11).
