Éoliennes Volantes: Airborne Wind Energy Activities at the Gipsa-Lab
Ahmad Hably, Jonathan Dumon Gipsa-Lab, Grenoble Institute of Technology During the last 4 years, several interesting theoretical and
practical actions were carried out by a team of Gipsa-lab at the Institute of Technology in the domain of Air-borne Wind Energy. In addition, two Ph.D. theses were defended in 2014 [1].
The first thesis, by Mariam Ahmed, proposes several con-trol schemes to a kite generator system based on model predictive control and virtual constraint control dedi-cated for periodic systems. In addition, she has focused on grid integration of these systems. The mechanical power generated by the kite’s traction force is trans-formed into an electrical one via a permanent magnet synchronous machine and injected in the grid or used to supply an isolated load after passing a power electron-ics interface. These control schemes have been devel-oped for grid connected or stand-alone operation and are tested in a hardware-in-the-loop simulator [2].
In the second thesis, Rogelio Lozano Jr. has worked on the modelling and control of a kite system. He proposed an observer-based control for energy production with a rigid wing generator system in a yoyo trajectory. He has also studied flying kites in the absence of wind using the reverse pumping principle. In addition, an indoor wind tunnel has been built in order to validate the different prototypes and control schemes proposed. Some out-door tests have been performed [3].
In this presentation, an overview of the Gipsa-lab’s present and future activities in the domain of Airborne Wind Energy will be given. Recent results obtained for the energy production control of an experimental
Mag-nus cylinder in presence of wind gusts will be presented. A mathematical dynamical model of a Magnus cylinder has been proposed and experimentally identified. An observer-based control strategy, which has been success-fully applied for a rigid wing prototype, has been vali-dated successfully in a simulation environment. This con-trol is implemented and validated experimentally in our indoor wind tunnel.
