Improvement of PMSG-Based Wind Energy Conversion System Using Developed Sliding Mode Control

In recent years, regulating a wind energy conversion system (WECS) under fluctuating speed and enhancing the quality of electricity provided to grid has become hard challenge for many academics. The current research provides better control strategy decrease occurrence chattering phenomena. Combined with Maximum Power Point Tracking (MPPT) pitch angle control, is possible increase performance efficiency Permanent Magnet Synchronous Generator (PMSG) based Wind Energy Conversion System. This study attempts initially regulate generator side converter track reference established by MPPT algorithm. And secondly, relieve problem associated conventional sliding mode (CSMC), proposed (PSMC) on novel smooth continuous switching control. Besides, suggested stability confirmed using Lyapunov’s function. complete was evaluated in MATLAB/Simulink (MathWorks, Natick, MA, USA) environment 2 MW PMSG’s power, random fluctuations show approach’s robustness, which then compared CSMC other common approaches available literature. simulation results reveal that recommended approach delivers good speed, accuracy, stability, output current’s ripple.
