Abstract

A method for compensating for flicker induced by a wind turbine power system connected to a power grid includes operating a power converter of the wind turbine power system based on a nominal reactive current command and a nominal torque command. In response to receiving a periodic torque command modifier, the method includes determining a reactive current command modifier for the power converter based on one or more operational parameters of the wind turbine power system and/or the power grid and the torque command modifier. The method also includes simultaneously modifying the nominal reactive current command as a function of the reactive current command modifier and the nominal torque command as a function of the torque command modifier. Accordingly, modifying the nominal torque command causes low-frequency voltage variations in the power grid and simultaneously modifying the reactive current command attenuates the low-frequency voltage variations.
