This paper focuses to improve wind turbine systems efficiency, in other words, to maximize the output power delivered by the wind turbine. To do this it is necessary to have a good controller. In this study, we use a nonlinear synergetic controller. Synergetic control theory is applied to reach the maximum power point tracking (MPPT) of a variable speed energy conversion system. A comparison with...
This paper offers an improved Tip speed ratio (TSR) technique for variable speed operating mode of grid connected doubly-fed induction generator (DFIG) system. As we know from the literature, the TSR is the fastest MPPT (maximum power point tracking) technique because it uses directly the wind velocity signal to compute the optimal rotational speed of the wind turbine, However, the significant wind...
