Claim 8:
9. A method of controlling operation in a wind turbine, the method comprising:
operating an electric generator of the wind turbine according to a speed reference value and a power reference value, the speed reference value and the power reference value being chosen along a linear operating trajectory in a power vs speed graph, the linear operating trajectory including a point corresponding to the nominal power and the nominal generator speed, and
selecting an angular position of the linear operating trajectory in the power vs speed graph,
wherein the linear operating trajectory is movable in the power vs speed graph between a vertical operating trajectory and an inclined operating trajectory, an angle being provided between the vertical operating trajectory and the inclined operating trajectory, the method including selecting a value of the angle between 0° and 90°.
