The main purpose of this thesis is to investigate the power system voltage stability and transient stability analysis. In the thesis, the Taiwan power system is selected for study. Based on the peak operation condition of Taiwan power system, the P-V and Q-V curves can be obtained by executing the voltage stability analysis in various N-1 and N-2 transmission line tripping contingencies. The P-V curve can denote the voltage collapse point and transfer power limit while the Q-V curve can identify the reactive power margin of the transmission lines. By the way, transient stability analysis is also performed to verify the system can be recovered to stable or not by examining the bus voltage and transmission line power flow after the contingency. In addition, the static var compensator are considered to be installed at the critical buses with different capacities to enhance the system stability and to avoid system from collapse.
