1. A method of controlling a plurality of wind turbines regarding a mechanical oscillation damping action, the method comprising:
obtaining for at least one wind turbine an oscillation damping power portion, the oscillation damping power portion being determined to dampen at least one mechanical oscillation related to the at least one wind turbine;
computing a correlation related value of the oscillation damping power portion with a comparison power output related to a wind park; and
adapting the oscillation damping power portion for the at least one wind turbine based on the correlation related value;
wherein the correlation related value is the empirical correlation coefficient between the oscillation damping power portion and the comparison power output taken over a time window.
