A system and method are provided for controlling a power generating facility. Accordingly, the facility-level controller determines a reactive-power-delivery coefficient for each power generating asset of the power generating facility. The reactive-power-delivery coefficient includes at least one of a reactive-power-generation coefficient and a reactive-power-transmission coefficient. The reactive-power-delivery coefficient is indicative of an impact on the active power production capability of each of the power generating assets due to a change in an amount of reactive power delivered to a point of interconnect. Based at least in part on the reactive-power-delivery coefficient, the facility-level controller determines a portion of a demand signal to be satisfied by each of the power generating assets.

A system and method are provided for controlling a wind farm during low wind speeds. Accordingly, the farm controller designates at least one of the plurality of wind turbines of the wind farm as a designated turbine. The designated turbine is operating in a full auxiliary mode when the speed of the wind acting on the wind farm is below a wind speed threshold. The remaining wind turbines are operated in a reduced auxiliary mode. The reduced auxiliary mode includes the disabling of at least one of pitching and yawing of the remaining wind turbines. When a power output for the designated wind turbine exceeds a power threshold, the farm controller directs at least one group of the remaining wind turbines to transition from the reduced auxiliary mode to the full auxiliary mode. During certain grid conditions, the transition between auxiliary modes may be delayed.
