Enhancing Resilience of Airborne Wind Energy Systems Through Upset Condition Avoidance

Airborne wind energy (AWE) systems are tethered flying devices that harvest resources at higher altitudes, which not accessible to conventional turbines. To become a viable alternative other renewable technologies, AWE required fly reliably and autonomously for long periods of time while being exposed atmospheric turbulence gusts. In this context, the present paper proposes three-step methodology improve resilience an existing baseline control system toward these environmental disturbances. first step, upset conditions systematically generated lead failure using subset simulation method. second used synthesize surrogate model can be predict upsets beforehand. final step avoidance maneuver is designed keeps operational minimizing impact on average pumping cycle power. The feasibility demonstrated example tether rupture during operation. As additional contribution novel transition strategy from retraction traction phase presented reduce probability significantly.
