碩士 === 國立中正大學 === 電機工程研究所 === 107 === The development of Taiwan's offshore wind power is one of the government’s policy objectives. However, a large-scale offshore wind power integration is bound to pose great challenges to the operation of existing power systems. How to maintain the voltage is one of the important issues. This thesis studies the integration of offshore wind farms with 2.4 GW and 6.5 GW into the Taiwan power system in 2024 and 2025, respectively. This thesis investigates the system voltage under different operating scenarios and analyzes the voltage control using the VSC-HVDC or HVAC transmission. In the simulation process, the software of the power system analysis, PSS/E, is used to complete the equivalent wind farm model, the models of HVAC and VSC-HVDC transmission systems, and the model of reactive power compensation component. Based on the simulation results, it can be highlighted that the importance of voltage control, the advantages of HVDC transmission, and the necessity of establishing a wind farm equivalent model after a large scale of offshore wind farms is integrated into the Taiwan power system.
