Abstract: The mechanical power of a wind turbine is modelled from a friction phenomenon perspective. Two models for the available power are proposed based on a relative speed between the wind speed and turbine blades. The main advantage of these new models is in the possibility of using real-time standard identification techniques for recovering their parameters value. Models are compared with a heuristic reference model showing good performance.

Keywords: wind turbines; power coefficient; mechanical power; relative speed; friction; modelling; wind energy; wind power; wind speed; turbine blades; real-time identification.
