摘要
小型離島電力系統常因距離大型電力系統較遠,且無海纜相連,故多以小型柴油發電機組供 應島上用電。然因發電燃料運送不便使得運輸成本較高,且其具高碳排放量之特性,導致離島供電 系統面臨著高經濟成本、環境成本等困境。因此,本文針對離島微電網系統進行經濟效益敏感度研 究,本文以桶盤嶼為探討案例,透過島上發用電資料蒐集與分析,以負載評估再生能源與儲能系統 設置容量,再經發電與成本的影響因子及其變動率探討,進行離島微電網系統的經濟效益敏感度分 析,以期降低島上發電成本與減少二氧化碳排放,達到建置澎湖低碳島的願景。透過本文的案例分 析,得知柴油發電成本對於微電網建置有較顯著的影響,而太陽光電及儲能系統成本降低有助於微 電網系統推動,此研究流程與步驟可作為不同離島型微電網建置參考與借鏡。

Small-scale outlying island power systems are usually far away from main power systems and are not connected by submarine cables, so small diesel generator sets are often used to supply electricity to the island. However, due to the inconvenient transportation of power generation fuels, the transportation cost is high, and its characteristics of high carbon emissions have caused the outlying island power supply system to face difficulties such as high economic costs and environmental costs. Therefore, this article conducts a research on the sensitivity of economic benefits to the microgrid system of an outlying island. This article uses Tongpan as a case study, through the data collection, analysis of electricity generation and consumption data on the island, the capacity of the renewable energy and energy storage system is evaluated based on the load. The impact factors of costs and their rate of change are discussed, and the sensitivity analysis of the economic benefits of the outlying island microgrid system is carried out in order to reduce the cost of power generation on the island and reduce carbon dioxide emissions to achieve the vision of building a low carbon island in Penghu. Through the case analysis in this article, it is known that the cost of diesel power generation has a significant impact on the construction of microgrids. The cost reduction of solar photovoltaic and energy storage systems will help the promotion of microgrid systems. This research process and steps can be used as a reference for the construction of different types of island microgrids.
