A wind park with wind turbines and airborne wind energy systems where a first zone and a second zone is defined for at least one of the airborne wind energy systems such that the risk of collision between apart of that airborne wind energy systems and a part of one of the wind turbines is higher when the airborne unit of that airborne wind energy system is in the second zone than when it is in the first zone, and different control parameters are applied to the control of at least one of the wind turbine and the airborne wind energy system depending on the position of the airborne unit relative to the defined zones.
