A huge number of wind turbine generators will be integrated into the existing power systems in the near future because it has been identified as one of the most promising field of energy industry. Wind turbines are required to remain connected to the grid during a fault condition so as to support constant power supply. It is therefore necessary to investigate the impact of wind turbine generators on the stability of power systems. This paper presents a comparative study of available wind generator types and examines the effect of penetration level on the power system. Simulations have been performed to compare and demonstrate the transient behavior of a typical 5-machine 22- bus system with and without wind power integration. The simulation results reveal that the transient behavior of wind generators has significant effect on the overall stability of power systems and the increase in penetration level may induce the instability into the systems.
