Abstract:
Optimization of power generation is important for Airborne Wind Energy Systems to increase their cost effectiveness and hence industry viability. In this thesis, an approach to optimal control of airborne wind turbine along with shape optimization of wind turbine is proposed. A simplified model of an airborne wind turbine, constrained for motion along the vertical direction is considered. The Panel method is used for analysis of flow field and pressure distribution on the airborne wind turbine. The results of this analysis are used to compute real-time lift forces acting on the turbine, which in turn give the power generated at each instant in time. An optimal strategy, using Dynamic Programming algorithm, has been developed to maximize the integral of instantaneous power generated, by adjustment of altitude and orientation of turbine.
