Comparison of Power Fluctuation between Optislip and DFIG Controlled Wind Turbines

In this paper, the operation and control strategies of two commercially available variable speed wind turbines, the Optislip and Doubly Fed Induction Generator (DFIG), areinvestigated in detail by Matlab/Simulink. The standard deviation of output power is compared below rated wind speedbased on measured wind speed profile. The impact of Optislip shaft inertia in the power fluctuation is also studied
