Systems and methods for operating a wind farm

A method for operating a wind farm having a plurality of wind turbines, the method comprising:

• determining a wind direction of a wind affecting the wind farm;
• identifying, via a controller, a turbine cluster comprising a subset of the plurality of wind turbines when the wind has the determined wind direction, the subset of wind turbines comprising at least an upwind turbine and a downwind turbine, wherein the downwind turbine is affected by a wake emanating from the upwind turbine;
• determining, via the controller, a difference between a freestream maximal cluster power output and a wake affected cluster power output for the turbine cluster based, at least in part, on a given wind speed affecting the wind farm;
• determining, via the controller, a mitigation setpoint combination for the subset of wind turbines, the mitigation setpoint combination being configured to establish a mitigated cluster power output, the mitigated cluster power output having a difference from the freestream maximal cluster power output that is less than the difference between the freestream maximal cluster power output and the wake affected cluster power output for the turbine cluster, wherein the determining of the mitigation setpoint combination for the subset of wind turbines further comprises:
• generating, via the controller, a cluster power model based, at least in part, on a correlation between a wake affected turbine power output for the downwind turbine and a wind velocity, an operational parameter of the downwind turbine, and an operating state of, at least, the upwind turbine;
• training, via the controller, the cluster power model via at least one of an operational data set or an environmental data set;
• determining, via the controller, a plurality of potential mitigation setpoint combinations for the subset of wind turbines for a plurality of environmental conditions corresponding to at least one wake sector based on the cluster power model, each of the plurality of potential mitigation setpoint combinations corresponding to a potential mitigated cluster power output;
• and
• selecting, via the cluster power model, one of the plurality of potential mitigation setpoint combinations corresponding to the potential mitigated cluster power output having a magnitude of the difference relative to the freestream maximal cluster power output that is less than the magnitude of the difference for each remaining potential mitigated cluster power output;
• and
• changing an operating state of at least one wind turbine of the turbine cluster based on the mitigation setpoint combination.
