To achieve the optimization control of airborne wind energy systems (AWEs) that adapt to the dynamic changes of wind shear
and to accomplish efficient wind energy capture
a model predictive control (MPC) strategy based on mixed Gaussian process(MGP) is proposed. Initially
a quantitative analysis of the key factor of AWEs operation
wind shear
is conducted. MGP is utilized to model the significant statistical characteristics of the wind shear profile
providing prior wind speed information for height-optimized control. Subsequently
an adaptive MPC strategy integrated with a genetic algorithm is established to balance the optimal operation height and energy dissipation
ensuring that AWEs operates at the ideal height while reducing the energy consumed for control
thereby enhancing the net power generation of AWEs. Finally
the proposed optimization control strategy is validated based on the real wind shear data from a high-altitude wind energy generation demonstration project in China. The results indicate that the strategy can effectively increase the net power generation of AWEs
with an average increase of 18.9% compared to traditional fixed tower structures and 9.6% compared to the extremum seeking strategy.
