A control system for controlling a set point of an individual power output of each wind turbine. The wind turbines are grouped into a plurality of groups of wind turbines and each group associated to a sub control unit. A main control unit is adapted to determine a set point for a total power output of each group based on a reference set point for an overall power output of the wind park and on data being indicative for current characteristics of the wind park and adapted to distribute the determined set points between the sub control units via main control signals being provided to the sub control units. Each main control signal is indicative for the set point. Each sub control unit is adapted to determine a set point for an individual power output.
