Aerodynamics and optimisation of wind power systems in complex terrain
By collaboration between Danish and Chinese experts in wind turbine aerodynamics, optimisation and control, and atmospheric turbulence, aim is to develop an integrated apporach, which provides reliable design tools to efficiently capture wind energy for wind turbines installed in complex terrain.
Wind energy production and loads on wind turbines are through their aerodynamics closely connected to atmospheric turbulence, the surrounding terrain and the influence of other turbines. Most existing models on rotor and wake aerodynamics neglect or simplify part of this interaction. The idea of this research collaboration between Danish and Chinese experts in wind turbine aerodynamics, optimization and control, and atmospheric turbulence, is to develop an integrated approach. The modelling will be built on existing experiences from developments of aerodynamic and atmospheric models. The developed model will be validated against existing and planned measurements. The present application is to provide reliable design tools to efficiently capture wind energy for wind turbines installed in complex terrain.
The subject of the DSF research project is aerodynamics and optimization of wind turbines in complex terrain. The purpose of the project is to explore the knowledge about wind turbine flows in complex terrain through collaboration between research institutions from Denmark and China and then establish techniques to model the turbine flow characteristics for use related to wind turbine optimization and control. The research areas cover aerodynamics, site optimization and control of wind turbines in complex terrain. The new knowledge obtained from the project includes the influence of terrain on the performance of the wind turbines in complex terrain and the influence of terrain on the wake development. Further, a new smart blade control using flaps and a feed forward control based on information of the inflow to the blade has been developed. The outcome of the research project will help to develop an advanced layout optimization technique for wind farms in complex terrain which will be used in the new EUDP Sino-Danish project entitled “Wind Farm Layout Optimization in Complex Terrain”.
