Systems and methods for controlling a wind turbine

A method for controlling a wind turbine when a current wind event is acting on the wind turbine, the wind turbine part of a wind farm having a plurality of wind turbines, the method comprising:

• receiving, at a controller, a yaw offset function based, at least in part, on wind direction data, and on position data from at least one wind turbine of the plurality of wind turbines;
• preparing, via the controller, a yaw bias correction function based, at least in part, on the yaw offset function, and on wind speed measurement data and wind direction reference data of a wind event acting on at least a portion of the wind farm;
• receiving, at the controller via one or more meteorological sensors, wind speed measurement data of the current wind event acting on the wind turbine of the plurality of wind turbines;
• receiving, at the controller via one or more position orientation sensors, position data of at least a nacelle of the wind turbine of the plurality of wind turbines, wherein the position data establishes a heading for the nacelle of the wind turbine during the current wind event;
• applying, via the controller, the yaw bias correction function using the position data and the heading of the nacelle of the wind turbine, and using the wind speed measurement data of the current wind event acting on the wind turbine, to correct a yaw offset signal used in controlling the wind turbine;
• and
• controlling, via the controller with the corrected yaw offset signal, the wind turbine.
