摘要

本論文先針對金門電力系統架構作介紹，包含柴油發電機組模型與參數、風力發電機模型、太陽能模型、儲能模型、變壓器、配電饋線與負載等資料。本研究使用PSS/E-33版本執行金門電力系統在尖峰、離峰不同負載下的暫態穩定度分析，探討當金門未來的再生能源占比達10MW時，在不同情境下（如：塔山柴油機組故障、夏興變電所變壓器故障、莒夏一路線路故障、風機出力由100%降至50%、風機出力由50%降至出力下限、太陽能出力由100%降至50%等），模擬系統的頻率變化，觀察其結果是否觸碰低頻電驛的卸載設定值。
　　本研究亦提出未來可行最大再生能源的裝置總量分析，使用三種不同的假設進行模擬，包括：暫不考慮金門既有調度準則，以最大化再生能源總量進行穩定度分析、在塔山電廠新增2台小型柴油機組配合調度、加入儲能系統模擬再生能源增加的同時儲能是否能穩定系統頻率等。本研究成果，相信對於目前政府正在執行的金門低碳島建置計畫有一定的助益。

This thesis introduces the power system models of Kinmen Island, including generator model and parameters, wind turbines model, solar model, energy storage model, transformer, feeder and loading data, etc. This study uses PSS/E-33 to execute the load flow analysis and transient stability analysis of Kinmen Island power system under the peak load and off-peak load. This study performs the frequency variation simulation in different situations, and then observes whether the result touches the under frequency settings when the renewable energy accounts for 10 MW.
　　This study also proposes the maximum amount of renewable energy available in the future, and simulates in three different ways. Such as ignore the Kinmen's existing scheduling guidelines, to maximize the amount of renewable energy for system stability analysis, two new small diesel units were added to Tashan Power Plant, which will be coordinated with the increase of renewable energy in the future, and whether the system frequency can be stabilized when the energy storage system is added and the renewable energy is increased. The results of this study, is believed to have contribution foe the implementation of the Kinmen Low Carbon Island Project currently being implemented by the government.
