A method 200 for controlling a wind turbine system may generally include controlling a wind turbine 10 to operate at a speed and torque setting within a permissible operating region defined between maximum 302 and minimum 304 operating curves, receiving a speed de-rate request and/or a torque de-rate request to de-rate the wind turbine 10 based on a limiting constraint of the wind turbine system, determining an adjusted speed setting 322 and/or an adjusted torque setting 332 for the wind turbine 10 based on the speed de-rate request and/or the torque de-rate request, determining whether an adjustment of the wind turbine operation to the adjusted speed setting 322 and/or the adjusted torque setting 332 would place the turbine 10 outside the permissible operating region and, if the adjustment would place the operation outside the permissible operating region, adjusting the speed setting and/or the torque setting to a new speed and/or torque setting defined along the maximum 302 or minimum 304 operating curve.
