US Patent 10316823 Wind turbine group control for volant animal swarms

Groups of wind turbines at a wind farm are controlled based on detection of volant animal swarms. A risk score is defined for each of a plurality of wind turbine groups of the wind farm at a default risk score based on predetermined data. A respective operational parameter is set for each wind turbine of each of the wind turbine groups based on the respective risk score. The presence of a volant animal swarm is detected in a region associated with a given one of the wind turbine groups via a volant animal detection system. The risk score of the given one wind turbine group and an adjacent wind turbine group is changed from the default risk score to temporary risk scores in response to detection of the volant animal swarm.
