1. A method for controlling a wind farm having a plurality of wind turbines electrically connected to an electrical grid at a point of interconnection, the wind farm being controlled by a farm-level controller, each of the plurality of wind turbines having a turbine-level controller communicatively coupled to the farm-level controller, the method comprising:
receiving, via one or more of the turbine-level controllers, an indication of at least one of a communication loss between the turbine-level controllers and the farm-level controller, a detection of an absence of reactive power regulation by the farm-level controller, or a reactive power command of the farm-level controller being equal to or above a saturation threshold during transitioning between a baseline operational mode and a reactive power mode, the reactive power mode being characterized in that only reactive power is generated; and
upon receipt of the indication, adjusting a reactive power response of one or more reactive power regulators of the turbine-level controllers so as to avoid an overshoot reactive power event or an undershoot reactive power event at the point of interconnection.
