A Probabilistic Approach to the Evaluation of Energy Availability of Fixed and Variable Speed Wind Turbines Conference Paper uri icon


  • © 2017 IEEE. This paper proposes a probabilistic approach to evaluate the power generation of wind turbines operating with fixed and variable speed. The wind turbine model considers the speed-control mode of the power curve, which relates the mechanical power of a turbine to the wind speed. A Weibull probability distribution is fitted to represent the wind speed. Thus, the wind generation estimation combines the random characteristics of the wind speed with the power curves of both fixed and variable speed turbines and analyses their performances. A clustering approach is also proposed for data reduction and expected energy availability. Case studies on a test system are presented using wind data from a Brazilian site, and the reliability indexes obtained for fixed and variable speed turbines are compared using both the distributional and clustering approach.
