A control algorithm to increase the efficient operation of wind energy conversion systems under extreme wind conditions

This paper aims to increase the power production of gearless permanent magnet synchronous generator (PMSG) based wind energy conversion systems (WECS) in strong (greater than 25 m/s) speed regions. In general, most turbines cut off when is over cut-out rate; as a result, generation farm decreases. study introduces look-up table pitch angle and rotational control generate extra region. Consequently, WECS can produce electric at reduced level until reaches 35 m/s possibility shutting down The proposed algorithm decreases mechanical stress turbine by decelerating rather torque Furthermore, model predictive (MPC) replace PI controller inner current loop rotor loop, thereby improving performance stator track. method validated Matlab/SimPowerSystem software. simulation result confirms that reduces shutdown guarantees temporally conditions.
