Abstract: Systems and methods for operating a wind farm are disclosed. The method includes detecting an operating condition of an upwind wind generator, the upwind wind generator located upstream of a downwind wind generator relative to a wind flow direction. The method further includes communicating a control signal to the downwind wind generator. The control signal is based on the operating condition. The method further includes beginning to adjust the downwind wind generator according to the control signal before the wind flow is experienced by the downwind wind generator.

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.
