New design and comparative study via two techniques for wind energy conversion system

Introduction. With the advancements in variable speed direct drive design and control of wind energy systems, efficiency capture these systems is also increasing. As such, numerous linear controllers have been developed, literature, for MPPT which use characteristics turbine system. The major limitation all those that they linearized model cannot deal with nonlinear dynamics a However, real exhibit controller required to handle such nonlinearities real-world systems. novelty proposed work consists development robust ensure maximum power point tracking by handling system making it against changing environmental conditions. Purpose. In beginning, sliding mode has considered as one most powerful techniques, this due simplicity its implementation robustness compared uncertainties external disturbances. Unfortunately, type suffers from disadvantage, is, phenomenon chattering. Methods. So paper order eliminate phenomenon, novel non-linear algorithm based on synergetic proposed. objective maximize extraction conversion eliminating chattering good quality fixing coefficient at value Tip Speed Ratio maintained optimum value. Results. performance validated MATLAB/Simulink environment. simulation results show effectiveness scheme, suppression law.
