With the capacity increase of wind farm, more influence will be exerted on the power system. A Low-frequency oscillating phenomena often occurs in power system with large-capacity wind turbines and will prevent the transmission of power between regions and may result in system instability. Therefore, small signal stability of the power system with wind farm becomes an important issue. The main purpose of this thesis is to investigate the dynamic analysis of power system with wind farm. The study systems include a two-area power system and Changpin area of Taiwan power system in which wind turbines are installed as part of power source. The damping and frequency of the electromechanical oscillation modes are calculated through frequency domain analysis. The study results show that the small signal stability of power system is affected by the capacity and the point of interconnection of wind farms.
