- Abstract
Achieving fast-tracking speed, high efficacy of maximum power point tracking (MPPT), absence of any wind speed measurement devices, and high performance under unpredictable wind speed along with an efficient control system is the recent trend in modern wind energy generation systems (WEGSs). This article studies two current control schemes for the control of a variable-speed WEGS based on a large-scale grid-connected permanent magnet synchronous generator (PMSG). An indirect optimal torque control (OTC) algorithm along with a fuzzy logic controller (FLC) have been implemented on the machine side converter (MSC) to diminish the installation cost and improve the overall efficiency of the studied wind system. Several distinct research studies highlighted that the PMSG suffers from the poor performance of the proportional-integral (PI) controller, especially in the event of variations in wind speed, FLC is proposed here as a substitute for the PI controller to eliminate its limitations. Both the FLC and PI controller are designed and implemented to fulfill the obedient performance of the current control loop of MSC. Moreover, a comparative study has been done between them under two different wind speed profiles (step change of wind speed, and real fluctuations of wind speed). MATLAB/SIMULINK software is used to validate the performance of the studied control schemes. The results of the simulation show the supremacy of the FLC compared to the PI controller and the veracity of the FLC as a vital option to the PI controller's drawbacks. [ABSTRACT FROM AUTHOR]
