| Summary: | 碩士 === 國立臺灣海洋大學 === 電機工程學系 === 105 === The main purpose of this thesis is to investigate voltage stability of power system with both wind generation and photovoltaic generation. The power flow and bus voltage variation are analyzed for the system with different penetration of renewable energy. Then according to the interconnection criteria, the current loadings are investigated to determine whether the system meets relevant specifications. Both P-V Curve and Q-V Curve methods are used for analyzing the voltage stability limit of the system which is under the normal operation as well as contingencies. Results show that after the renewable power is incorporated into power system, the current loading of transmission lines becomes higher, and bus voltage variation and voltage stability are also affected with different degree of impact on buses of different voltage levels. The bus voltage level is higher, the impact will be smaller. Finally, it can be found that the system with BESS (Battery Energy Storage System) has higher power margin and thus the system stability has been enhanced.
