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.
