    Fuzzy Logic Based Robust DVC Design of PWM Rectifier Connected to a PMSG WECS under wind/load Disturbance Conditions
    (جامعة الوادي - university of el oued, 2019-05-20) Saidi, Y; Mezouar, Y; Miloud, A; Benmahdjoub, M. A; Yahiaoui, M M
    Permanent Magnet Generator has been widely used in Variable-Speed Wind Energy Conversion System (VSWECS). Fuzzy Logic Control (FLC) of the generator side converter has the ability to have a good regulation of the DC-link voltage to meet the requirements necessary to achieve optimal system operation, regardless of the disturbances caused by the characteristics of the drive train or some changes into the DC-load. The main focus of this paper is to present a model for a three phase voltage source space vector pulse width modulation (SVPWM) rectifier which is connected to a PMSG in a wind turbine system, where a direct voltage control (DVC) using FLC based on voltage orientation strategy is used to control the mentioned rectifier. The control algorithm employs fuzzy logic controller to effectively achieve a smooth control of DC-link voltage under wind/load perturbation conditions. Some simulation results, using Matlab/Simulink, are presented to show the effectiveness of the SVPWM rectifier Connected to a PMSG WECS with the proposed control strategy.

    Modeling and Comparative Study of Speed Sensor and Sensor-less based on TSR-MPPT Method for PMSG-WT Applications
    (جامعة الوادي - university of el oued, 2018-11-13) Saidi, Y; Mezoua, A; Miloud, Y; Benmahdjoub, M; Yahiaoui, A; Modeling, M
    This paper aims to present a study and comparison between two approaches for maximizing the power delivered by the WT-S (wind turbine system) which is called (MPPT-Control) based on TSR method (tip-speed ratio): first method is based on MPC (maximum power control) with wind speed measurement (TSR-MPCWSM) and the second one based on MPC with wind speed estimation (TSR-MPCWSE). These methods are analytically compared to illustrate TSRMPPT and power smoothing capability delivered by the aerodynamic turbine system. The dynamic performance, robustness and fast approximation of the optimal value are proved with the simulations (MATLAB/Simulink® software).
