The expansion of wind farms and the increase in their capacities impact the dynamic behavior of power systems significantly. These dynamics can only be captured accurately by detailed modeling of wind conditions as well as key equipment in the wind farm such as turbines, generators, controllers, compensation equipment and the composition of the operational turbines in the farm. Because of the large number of wind turbines in a typical farm and the variation in their operation, establishing an acceptable low order dynamic model for the entire farm is a challenging task indeed. This is because of the large number of wind farm turbines and the often lack of information at the utility control center on the detailed operational statuses of every turbine in farm at all times. In this paper, an aggregated model of wind farm based on the dynamics measured at the point of interconnection is proposed. These dynamics are naturally present due to the variations in wind speeds as well as wind gusts. The model is adaptive and can accommodate variations in wind farm operations and seasonal wind conditions.
