Abstract: The present disclosure is directed to a method for minimizing energy loss caused by yaw untwist of a nacelle of a wind turbine. The method includes monitoring, via at least on sensor, one or more wind conditions near the wind turbine. The method also includes processing, via a controller, the one or more wind conditions for a given time interval. Further, the method includes monitoring, via the controller, a position of the nacelle. The method also includes triggering, via the controller, a yaw untwist operation when the position of the nacelle has rotated from an original position above a predetermined yaw threshold and the processed wind conditions are below a predetermined wind condition threshold.

Abstract: A method for controlling a wind farm electrical power system is presented. The wind farm electrical power system includes a controller and a plurality of wind turbines electrically connected to an electrical grid through a point of interconnection. Each wind turbine includes a voltage regulator. The method includes receiving, via the controller, one or more electrical signals associated with the point of interconnection for a frequency domain. Further, the method includes estimating, via an estimator of the controller, a voltage sensitivity of the electrical grid using the one or more electrical signals. Moreover, the method includes dynamically controlling a voltage of the wind farm electrical power system at the point of interconnection based on the voltage sensitivity.

Abstract: The present subject matter is directed to a system and method for operating a wind turbine. More specifically, the system and method determines a dynamic cut-in wind speed for the wind turbine based on one or more environmental conditions. In one embodiment, the method includes providing a predetermined cut-in wind speed for the wind turbine based on at least one estimated environmental condition for a wind turbine site; determining one or more actual environmental conditions near the wind turbine for a predetermined time period at the wind turbine site; determining a variance between the at least one estimated environmental condition and the one or more actual environmental conditions; calculating a dynamic cut-in wind speed based on the variance; and, operating the wind turbine based on the dynamic cut-in wind speed so as to increase wind turbine operational efficiency.

Abstract: A system and method for operating a wind farm connected to a power grid, the wind farm having one or more wind turbines includes implementing a shutdown mode for the one or more wind turbines of the wind farm in response to receiving a shutdown command. The shutdown mode includes disconnecting the one or more wind turbines of the wind farm from the power grid via one or more respective individual turbine controllers and reducing, via the individual turbine controllers, a rotor speed of the one or more wind turbines to a cut-in speed. After the shutdown command is cleared, the method further includes reconnecting the one or more wind turbines to the power grid.

Abstract: The present disclosure is directed to a system and method for mitigating ice throw from one or more rotor blades of a wind turbine during operation. The method includes monitoring one or more ice-related parameters of the wind turbine. Thus, the ice-related parameters are indicative of ice accumulation on one or more of the rotor blades. In response to detecting ice accumulation, the method also includes implementing an ice protection control strategy. More specifically, the ice protection control strategy includes determining a yaw position of the wind turbine and determining at least one of a power set point or a speed set point for the wind turbine based on the yaw position.
