????????? ??????? ???? ???? ???? ??? ???????? ???? ???????? ??????Index. décimale : 622 Electro-Technique Résumé : This work deals with the analysis, design, and control of grid-interfaced permanent magnet synchronous generator (PMSG) based variable speed wind energy conversion system (WECS) for power smoothening with maximum power point tracking (MPPT) and power quality conditioning capabilities. The power electronic device used usually as intermediate between the wind generator and the grid is a full rated two levels back to back converter (BTB). The BTB converter is constituted of tow PWM converters, the machine side converter (CCM) works as a rectifier and the grid side converter works as an inverter. Several DPC based control techniques (conventional DPC, predictive DPC and DPC based sliding mode approach (DPC-SMC)) have been applied on a PWM rectifier under ideal and disturbed supply voltage conditions. Moreover, the sensorless grid voltage control scheme is presented using sliding mode estimator. Two versions of sliding mode estimator have been implemented, one for the ideal and the other for the disturbed supply condition. After an extensive set of simulations following by experimental validation, the grid voltage sensorless DPC-SMC technique has been introduced the best performance with high estimation accuracy and power quality. On the other hand, in a wind energy conversion system, the grid side inverter function is ensuring permanent and stable transmission of energy to the grid. However, the extensive use of nonlinear loads led to decrease the quality of energy at the point of common coupling (PCC). Thus, the idea is to extend the inverter function with a harmonic compensation capability. Hence, analysis, design, and control of shunt active power filter (SAPF) under ideal and disturbed supply voltage conditions were an important part of this thesis. Then, an improved control circuit for SAPF system based on DPC concept combined with a Kalman filter as synchronization technique has been introduced. Furthermore, a modified voltage sensorless DPC concept based predictive model and modified sliding mode estimator has been proposed to be applied for a SAPF. Finally, the overall circuit control of the WECS system is based on the optimal findings, which are developed in this work. For the CCM and CCR converters, we have been applied the DPC-SMC and the proposed DPC approach respectively, as optimized solutions.

This manuscript treats the modeling, the control and the simulation of a wind energy conversion system driven DFIG on a 1.5MW. The turbine through a gear box drive the DFIG connected directly to the grid by its stator, but also by back-to-back converter placed between the rotor and the grid. The different components of the conversion chain are modeled. The Power Extraction Technique (MPPT) adjusts the speed of the turbine to the wind speed to maximize power. The wind turbine based DFIG control comprises both the rotor side converter (MSC) and grid side converter (GSC) controllers. The vector control (VC) based on flux stator oriented control, the direct power control (DPC) based on selecting the appropriate rotor voltage vectors and the errors of the active and reactive power, and the combined (VC-DPC) proposed between the VC and DPC for the control of MSC to decoupled active and reactive stator power control exchanged between the machine stator and the grid. The GSC whose main role is to keep the DC link voltage constant, guarantee sinusoidal grid current and the reactive power is set to 0, in order to have a unit power factor in the grid side, the GSC is controlled by the DPC, the control of the generator speed is assured by PI and IP controllers. Simulation results of the complete wind energy conversion chain based on 1.5 MW DFIG with the various strategies used in hypo and hyper synchronous mode using Matlab/Simulink are presented, discussed and demonstrate the effectiveness of the proposed control strategy during variations of wind speed, active and reactive power, robustness, against the machine parameter variations, the dynamic response and power ripple.
