A wind park controller and control method for a wind park (10) are described. The wind park comprises a plurality of wind turbines (20) and an Energy Storage System (24) connected to one another by means of a low voltage power network (22, 25), which is in turn coupled to the grid. The controller determines a number of operating parameters of the wind turbine gearbox or drive train, and calculates a gearbox or drive train health metric. This can include a measure of the gearbox lifetime. The controller also determines one or more power characteristics of the wind turbine generator or the point of common coupling (26) to determine a power mismatch indication. Based on the power mismatch indication and said gearbox or drive train health metric, the controller determines a power command for the Energy Storage System and wind turbines based to improve the gearbox health and lifetime.

An electrical energy generator system for an aircraft, the system including a streamlined fairing containing at least one turbine housed in the front portion of the fairing, and an electrical energy generator connected to said turbine. The front portion of the fairing is fitted with air admission means that are movable between an open position in which the turbine is exposed to the stream of air outside the fairing and a closed position in which the turbine is masked inside the fairing. The system may serve to reduce the aerodynamic drag caused by turbulence present at a wing tip for a conventional wing having sharp edges during stages of takeoff, climbing, and cruising; and during stages of descent it makes it possible to recover the kinetic and potential energy that has been accumulated by the aircraft during its stages of climbing and cruising.
