Method of Operating a Wind Turbine, Controller Usable for Operating a Wind Turbine, and Wind Turbine

A method of operating a wind turbine, a controller usable for operating a wind turbine, and a wind turbine are provided. The wind turbine includes a voltage converter being connectable to a power grid via a filter arrangement. The method includes determining a line voltage; and adding the determined line voltage to the output of the voltage converter with a time delay, wherein the time delay is adjusted such that resonant effects occurring at the filter arrangement are decreased.
