Method of operating a wind turbine

Abstract: a method of operating a wind turbine is provided. the wind turbine is operable in plural different operating modes that differ by at least one of lifetime consumption of the wind turbine and energy production by the wind turbine. a sequence of operating modes is determined for a future period of time, wherein an optimization parameter is estimated based on at least one estimated external parameter. the method further includes obtaining a current value for the at least one external parameter and determining an actual operating mode for the wind turbine for a current point in time, wherein the determining of the actual operating mode comprises estimating an adjusted optimization parameter for plural sequences and for the current value of the at least one external parameter, and selecting the actual operating mode based on the estimated adjusted optimization parameters. the wind turbine is operated in the determined actual operating mode.
