Improving Power Generation in Rigid‐Wing Groundgen Airborne Wind Energy Systems Using Feedback Control—A Parametric Study

open access: yesWind Energy, Volume 29, Issue 4, April 2026.
ABSTRACT This paper explores different reel‐out strategies in a simulated environment to improve the power generation capability of Kitemill's KM1 prototype. The KM1 is a rigid‐wing groundgen airborne wind energy system that flies in circular loops during its power production phase. Firstly, we investigate the impact of flight and ground winch control.
