Abstract: A method for operating a wind farm connected to a power grid that demands a reactive power requirement that varies with active power includes monitoring a wind speed at each of the plurality of wind turbines in the wind farm. When the wind speed is within a cut-in wind speed range, the method includes determining a reactive power margin of the wind farm based on the reactive power requirement at an active power output corresponding to the wind speed and a reactive power availability of each of the plurality of wind turbines at the wind speed. The method also includes determining a lowest possible cut-in rotor speed for each of the plurality of wind turbines that satisfies the reactive power margin. Further, the method includes commanding each of the plurality of wind turbines to cut-in and begin to produce power at the lowest possible cut-in rotor speed that satisfies the reactive power margin.

Abstract: A system and method are provided for controlling a wind farm. Accordingly, a demand signal is received from the electrical grid. The farm-level controller also receives a plurality of capability metrics from each wind turbines, which include, at least, a steady-state power availability, a transient power availability and a responsive capability of each wind turbine. The farm-level controller determines a power production capability profile for each wind turbine and determines the availability of each wind turbine to meet at least a portion of the demand signal based on the power production capability profiles. The farm-level controller also determines which portion of the demand signal to be satisfied by each wind turbine based on the availability and the power production capability for each wind turbine.
