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.

Recorded RES distribution systems are becoming more important and should play a bigger role in the near future. Connecting RES facilities to distribution networks involves addressing several technical challenges for grid operators, who perceive renewable energies as a source of complications for the electricity system. Congestion is one of the most complicated issues that can arise when integrating renewable energy into the electrical system that cannot be left without treatment. For that, this work examines a corrective method of an overloaded electrical system in the presence of a wind farm integrated in a distribution network, taking into account the cost of congestion. Attempts were done in order to eliminate the overloads and monitor the power flow on the lines using as the first suggestion the UPFC universal power flow controller. The second proposed methodology is the ELM Extreme Learning Machine. This algorithm is extremely fast, having excellent performance in terms of generalization. The fundamental point of this successful study is the relief of congested structures. In addition, other objectives are achieved: improvement of the voltage profile, avoidance of load shedding, reduction of losses and congestion cost. The proposed congestion management methods were tested for an Algerian power system with 22 busbars at the city of Adrar. The results presented in this work were discussed and compared. These results show an improvement in the behavior of the electrical network.
