Some essential differences exist between a wind power generation system and a conventional generator. The impact on the transient stability of a power system must be explored if wind power, particularly large-scale wind power, is to be integrated into existing power systems. In a wind power system, one of the main issues in power system safety and operation is rotor angle stability. Rotor angle stability is determined by its critical clearing time (CCT).This study examines the grid connection of 1833 MW of wind power capacity into the existing Taipower system and explores the impact of integrating large-scale wind power on a power system’s CCT. It was observed via simulation that the penetration of wind power in the system peaks at 12%. The simulation uses PSS/E power system analytical software to establish a 1626-bus power system for Taiwan and contains details of power grid component parameters and wind turbine models. We assume that a balanced three-phase short-circuit ground fault occurs on each 345 kV bus. The CCT for each case is then acquired. Finally, this study compares and investigates the causes of differences in system CCT before and after integrating 1833 MW of wind power into the Taipower system.
