- Abstract
- Airborne wind energy (AWE) has recently gained much interest due to its significant potential as a green energy source. Until now, most studies have investigated single AWE systems, as the existing systems are so far operated as a single unit. However, AWES wind farms will be essential for the large-scale development of the technology. In the present study, we develop a Large-Eddy Simulation (LES) framework to investigate AWES, also in farm configurations. The AWES main wing is modeled using an Actuator Line (AL). For the dynamics, we use the 6-DOF dynamics model of AWEbox. Therefore, it requires the implementation of control surface models in addition to the AL. In this work, we investigate a two-kite configuration where the second kite flies in the wake of the first one. As shown previously, the NMPC controller can handle quite well high turbulence intensity. Here, we investigate its ability to remain on the desired trajectory when subjected to stronger perturbations (i.e., from the leading kite’s wake). We found that the second kite harvested 5% less than the first one. In upcoming work, other cases and trajectories will be considered.
