Trends in grid integration of renewables. Case of Doubly Fed induction wind generator

This paper deals with investigations in integration of renewable energy sources in the electrical network. In fact the liberalization of electricity market and the development of decentralized production, induce many scientific and technical problems in electrical engineering and thus renewable energy production. It is obvious that these problems come from the technology integrated into the electrical grid, which influence the global management of the distribution system. That´s why it is important to make sure that these decentralized productions participate actively in the grid integration. A particular study of these networks is highlighted in this paper. The integration of a particular wind turbine of 1.5 MW and its impact on the distribution network will be presented. The simulations of scenarios of these systems are carried out with Matlab Simulink TM.
