Claim:
1. A method for operating a horizontal axis wind turbine, the wind turbine including a rotor with the rotor including a rotor blade, wherein the rotor is rotatably coupled to a nacelle, and the rotor is rotatable about a horizontal rotor axis extending through the nacelle, and wherein the nacelle is rotatably coupled to a tower, the nacelle being rotatable in a yaw plane about a yaw axis, the method comprising: determining a wind direction; determining a yaw angle setting, wherein the yaw angle setting deviates from an alignment of the rotor axis and the wind direction in the yaw plane; determining wind shear, wherein the yaw angle setting is determined as a function of the determined wind shear; yawing the nacelle to the yaw angle setting; and, operating the wind turbine.
