1. A method of controlling plural offshore wind turbines of a wind park regarding a mechanical oscillation damping action, the method comprising:
obtaining wave characteristic information indicating a characteristic of at least one sea wave;
obtaining wind turbine operational state information of the plural wind turbines, including wind turbine yaw direction information;
obtaining wind characteristic information; and
controlling the wind turbines regarding the damping action based on the wave characteristic information and/or the wind turbine operational state information of the plural wind turbines and/or the wind characteristic information, such that a power oscillation of a total power output of the wind park is reduced;
the method further comprising estimating, based on the wave characteristic information and/or the wind turbine operational state information and/or the wind characteristic information and/or based on an oscillation excitation characteristic, a characteristic of a damping power component to be added to a wind turbine power reference, to dampen at least one mechanical oscillation related to the respective wind turbine; and
wherein the method further comprises:
wherein estimating the characteristic of a damping power component includes considering locations of the wind turbines and wave travel times, to estimate points in time when the individual wind turbines are hit by the wave; and/or
determining a total damping control related power output or a total power output of the wind farm based on the estimated damping power components of the wind turbines, and configuring the characteristic of the damping power component for each of the wind turbines such that the power oscillation of the total power output of the wind farm is reduced, wherein controlling the wind turbines comprises controlling the wind turbines according to the configured characteristic of the damping power, by supplying, for each wind turbine, a control signal as a sum of the wind turbine power reference and a damping signal defined by the configured characteristic of the damping power components for the individual wind turbine.
