(Système Inertiel de Stockage d’Énergie) SISE Index. décimale : 622 Electro-Technique Résumé : The objective of this thesis consists for realizing a wind energy conversion system with a good compromise between cost, energy efficiency, system performance and quality of energy supplied to the grid. To achieve this aim, we have realized a modeling, a control and a simulation of wind generator which consists of a wind turbine, a Doubly Fed Induction Machine, a cycloconverter and a control block. The stator of this machine operating as a generator is connected directly to the grid while the rotor is connected via the cycloconverter which can control all the wind energy system. The stator flux oriented control technique, the sliding mode control, the CWCC (Cosine-Wave Crossing Control) technique and the MPPT (Maximum Power Point Tracking) control have been applied on the control block to control independently the active and reactive powers delivered to the grid by the generator and to extract the maximum power. The integration of a Flywheel Energy Storage System (FESS) between the wind generator and the grid has been realized to maintain the constancy of the
power sent to the grid, following the instability of the wind. Simulation results have been presented to validate and interpret the global operation of the proposed system.

?????? ?????? ??????? ???????Index. décimale : 621 Electronique Résumé : This work focuses on the introduction of optimization techniques in fractional adaptive control systems and on optimized approximation of fractional systems with reduced order models for identification and control purpose. Indeed, a new technique of approximation has been proposed in this direction, using the DE (differential evolution) technique while showing its advantage compared to other famous techniques such as those developed by Charef or Oustaloup.
Fractional adaptive control laws with optimized parameters are developed in order to improve the control system behavior: In the case of fractional order linear systems, a model reference PID control based on a new optimization algorithm (Moth-Flame) has been proposed. In the case of fractional order chaotic nonlinear systems, the following approaches are considered: a first control with adaptive sliding mode to improve performance and robustness. Since fuzzy systems are universal approximators, this property is exploited to strengthen the previous control law by an
adaptive fuzzy controller. For an optimal control, the parameters of the sliding controller are calculated by PSO optimization technique. In all the previous cases, the analysis of stability and robustness are justified by the Lyapunov approach. The theoretical results are validated by simulation examples.

The mostimportant one concerns the use of conventional energy sources which have a direct impact on increasing global warming. With a view of reducing the emission of greenhouse gases, sharing renewable energy and increasing our energy efficiency by transforming energy and introducing clean renewable energies that are not implemented in the field of energy, electricity production is no longer a matter of choice it becamean obligation for nation’s energy policy. In this context, to increase the durability and efficiency of the electric switching system of renewable energy on the one hand, and to improve the quality of energy supplied on the other, the purpose of the work presented in this thesis is primarily the implementation of high-performance nonlinear control law on asynchronous machine, secondly the improvement of process paths with disturbance rejection and finally ensuring stability and maintaining the disconnection between flow and torque despite changes in machine parameters. The simulation resultsobtained for motor operation show that the nonlinear and sliding mode control have best dynamic performance compared to those obtained through the application ofother control techniques. The best dynamic performances of the sliding mode control wereconfirmed by the implementation of this technique intocontrol scheme of the active and reactive power of doubly fed induction generator driven by wind turbine.The simulation results confirmthe exact decoupling and good trajectory tracking of the active and reactive power.

Index. décimale : 622 Electro-Technique Résumé : This work presents the study of the conversion of energy produced by Doubly Fed Induction generator connected directly to the network by its stator and driven by its rotor by two bidirectional converters. First, we presented the state of the art on wind energy and the conversion systems used (types of generators, most used configurations, etc ...). Then we exposed the mathematical models of each element of the wind turbine (the wind turbine and its command MPPT + the generator). Then we evaluated and examined two methods of vector control in power of the MADA in generator mode, the first to know: the direct command and the indirect command with the help of the correctors PI. According to the simulation results obtained, the indirect vector control with two cascade loops shows better performances for an invariant system. Finally, for nonlinear systems where with non-constant parameters, we applied the sliding mode control to control the active and reactive power with the use of an inverter controlled by the SVM technique to improve the electrical energy quality. to inject this energy into the electricity grid or we note that the simulation results show the reliability and robustness of this command which is given a good track of active stator power its reference with a negligible error.
