1. A method of controlling at least one wind turbine having a wind turbine tower and being connected to a utility grid, the method comprising:
providing a damping signal for counteracting an oscillation of the wind turbine tower;
providing a utility grid active power;
dynamically filtering the utility grid active power in dependence of the damping signal provided for counteracting the oscillation of the wind turbine tower to form a filtered utility grid active power; and
controlling the wind turbine in dependence of the filtered utility grid active power.
