Abstract: The present invention relates to a method for controlling a reactive power source in a wind power plant, the method comprising the steps of providing a wind turbine reactive power control signal and providing an active power reference signal, said active power reference signal being a measure of an active power production of the wind power plant. A control signal for the reactive power source is generated by combining the wind turbine reactive power control signal and the active power reference signal in such a way that the control signal for the reactive power source becomes a weighted signal of the wind turbine reactive power control signal. Moreover, the present invention relates to control units and wind power plants suitable for carrying out the present invention.

Abstract: The invention relates to a method for damping grid oscillations. The oscillations may be damped by controlling e.g. wind turbine generators to inject power to the grid in anti-phase with the grid oscillations. Instead of controlling one or more wind turbine generators to generate the same anti-phase power signal, a plurality of wind turbine generators are controlled so that each of them only generates a part of the anti-phase power signal, but so that all of the wind turbine generators in combination generates the entire anti-phase power signal.
