In the last decade, several research groups and companies around the world have been developing a new class of wind generators, aimed at harnessing the energy of winds blowing at high elevation above the ground. This kind of technology is usually referred to as Airborne Wind Energy (AWE) or High-Altitude Wind Energy. All of the proposed solutions exploit the high-speed flight of tethered wings, or...
The application to marine transportation of an innovative technology for high-altitude wind power generation is presented in this paper. The key idea is to pull a boat and to generate electricity onboard by exploiting the traction forces generated by automatically controlled tethered power kites. The kites are able to fly fast in crosswind conditions, between 200 m and 600 m above the sea, thus exploiting...
This paper presents simulation and experimental results regarding a new class of wind energy generators, denoted as KiteGen, which employ power kites to capture high altitude wind power. A realistic kite model, which includes the kite aerodynamic characteristics and the effects of line weight and drag forces, is used to describe the system dynamics. Nonlinear model predictive control techniques, together...
The paper investigates the control of tethered airfoils in order to devise a new class of wind generators able to overcome the main limitations of the present aeolian technology based on wind mills. A model taken from the literature is used to simulate the dynamic of a kite which can be controlled by suitably pulling two lines. Energy is generated by a cycle composed of two phases, indicated as the...
