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.

First of all, they have been made in off-line mode from experimental tests according to international standards. For a more precise determination of parameters in perturbed mode, we have developed on-line algorithms by applying different Kalman Filters (KF) in continuous and discrete time: The Discrete Kalman Filter (DKF) is the applied estimator in this study because it gives a good convergence compared to the real parameters; it is used in its various forms, traditional (TDKF) for linear systems or in its extended form (DEKF) when the system is non-linear. Another interesting application of DKF is when it is biased (DEKFB) because it will reduce the squared error (MSE) between the measured and estimated values of the system state variable; as a result, the standardized MSE (NMSE) can be minimized. Similarly, the standard deviation (STD) between the real and estimated values of the parameter can be limited to a tolerable percentage. The different KFs are implemented in a Matlab / Simulink environment in order to demonstrate the effectiveness of the DEKFB estimator compared to other Filters. The simulation results are acceptable since a good match between the real and estimated parameters has been obtained, which reflects the good noise filtering quality of the KF estimators designed and which can be used in on -line parametric identification in disturbed mode of low scale generator.
