Abstract

Methods are provided for controlling wind turbine loading. In one embodiment, a method includes the steps of determining a current thrust value for the wind turbine, calculating a thrust differential based on the current thrust value and a predetermined maximum thrust value, calculating a desired pitch offset value based on the thrust differential and a thrust sensitivity value, and adjusting a pitch of the wind turbine utilizing the pitch offset value.
