the challenge of climate change, but the specification of an electronic power interface is
subject to requirements not only for the renewable energy source itself, But also to its effects
on the operation of the feeding system. Such perturbations witch can degrade the quality of
the energy within an electrical network, especially in the high power systems connected to the
network. This thesis proposes solutions in order to improve the quality of electrical energy by
adopting direct power control (DPC) to PWM rectifiers connected to the distribution network.
The performances of these algorithms are analysed and tested experimentally as well as by
simulation. Finally, an example of a wind power conversion system based on a doubly fed
induction generator (DFIG) is carried out to evaluate and validate the results obtained.Diplôme : Doctorat En ligne : ../theses/electrotec/MEH7130.pdf Format de la ressource électronique : Permalink : https://bu.umc.edu.dz/md/index.php?lvl=notice_display&id=10472 Contribution à l'etude des redresseurs à commande par DPC pour une qualité de l'énergie.

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.
