This paper gave an overview of the impact of the integration of the wind turbines in an electric network. The number of wind turbines connected to a conventional electric network was increased causing some disturbances in the network. These disturbances are obviously remarked at the frequency and voltage levels. In this study, the modeling of the network was first presented. The load flow problem was described and solved using the Newton Raphson method. The maximum integration rate of the wind turbines was calculated after choosing the suitable node to implement the wind conversion chain. A reactive power compensation device was then inserted in this network. Simulation results show that the integration of the wind turbines causes voltage fluctuations. Voltage levels were improved after the injection of a reactive power while the rate of integration of the wind source energy does not change.
