Systems and methods for controlling a wind turbine

A method for controlling a first wind turbine of a plurality of wind turbines of a wind farm, the method comprising:

• determining a modeled performance parameter for the first wind turbine via a first model implemented by a controller, the modeled performance parameter being based, at least in part, on an operation of a designated grouping of wind turbines of the plurality of wind turbines, wherein the designated grouping is exclusive of the first wind turbine;
• determining, via the controller, a performance parameter differential for the first wind turbine at a plurality of sampling intervals, the performance parameter differential being indicative of a difference between the modeled performance parameter and a monitored performance parameter for the first wind turbine;
• implementing a second model, via the controller, to determine a predicted performance parameter of the first wind turbine at each of a plurality of setpoint combinations based, at least in part, on the performance parameter differential of the first wind turbine;
• selecting, via the controller, a setpoint combination of the plurality of setpoint combinations based on the predicted performance parameter;
• and
• changing an operating state of the first wind turbine based on the setpoint combination.
