碩士 === 中原大學 === 電機工程研究所 === 106 === In the future, a large amount of renewable energies will be added to the power system. It may cause a blackout in Taiwan, which will lead to an increase in the instability of the power system. However the change of climate and significant increase in electricity consumption of people, cause that the originally stable power system illuminates red light. Because the load is constantly increasing, and the shortage of reserve capacity is faced, and the construction of a new power plant is not easy, resulting in the possibility of insufficient power supply. If the load is greater than the power supply, voltage will be collapsed. The phenomenon of collapse will cause the problem of a blackout. The main purpose of this thesis is to analyze the Kinmen Island power system with the software of DIgSILENT, and to analyze the phenomenon of voltage collapse of the Kinmen Island power system. There may be many renewable energy sources in the future, so the existing power system is used to simulate the cause of voltage collapse. This thesis also tries to find out how to use energy storage or other means to improve voltage collapse problem. Because the voltage collapse will cause a blackout of power system, so to avoid this situation is definitively important. The analysis results will provide valuable comments to play for time for Kinmen power system.
