description	A yaw backup system 18, 20, 22 is provided. The yaw backup system 18, 20, 22 includes an energy storage medium 38, 40 for storing auxiliary power. The yaw backup system 18, 20, 22 also includes a yaw controller 42, 44 for coordinating delivery of power from the energy storage medium 38, 40 to a yaw motor 34, 35 for controlling a yaw angle of a wind turbine 12, 14, 16 during grid loss conditions. The yaw controller 42, 44 executes the steps of receiving wind direction signals over time from a sensor, altering a tolerance level of a wind turbine 12, 14, 16 based on changes in the wind direction signals over time and controlling delivery of power to the yaw motor 34, 35 from the auxiliary power of the energy storage medium 38, 40 based on the tolerance level to control the yaw angle for reducing a load on the wind turbine 12, 14, 16 induced by wind.
