  "textContent": "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.",
