再生能源與儲能系統整合於微電網之個案研究： 策略與經濟可行性

Abstract

本研究探討了再生能源與儲能系統在微電網中的整合應用，選取了澎湖桶盤嶼和台北市文山區興隆D2區社會住宅這兩個典型案例進行詳細分析。研究主要目的是通過個案資料及數據，分析適合的微電網型態、再生能源的主要來源以及儲能系統的最佳容量，並進行經濟效益評估。 桶盤嶼作為離島型微電網的典型案例，主要依靠柴油發電機提供電力，輔以太陽能光電系統和儲能設備。研究結果顯示，選擇太陽能光電系統作為再生能源來源是基於技術可行性、經濟效益、環境影響和社會接受度等多方面考量。雖然島上具備豐富的風能資源，但太陽能光電系統在安裝維護、運行穩定性以及對環境影響方面更具優勢。經淨現值法（NPV）和內部報酬率（IRR）的評估顯示，儘管初期投資較高，但桶盤嶼微電網系統具備良好的經濟效益。 台北市文山區興隆D2區社會住宅的案例顯示，社區型微電網在城市社區中的應用可以有效提升能源利用效率，降低對市電的依賴。本案例通過設置10KW太陽能光電系統和48KWH儲能設備，結合智慧能源管理系統（BEMS），實現了再生能源的有效利用和應急供電需求。儘管受到設置空間和法規限制的影響，該社區的儲能設備容量較小，但仍能在緊急情況下提供必要的電力支持。 智慧能源管理系統在微電網中的應用具有重要意義。BEMS不僅能夠監測和管理社區的用電資訊，還能通過智能算法進行能源調度，實現能源的高效利用。本研究中，BEMS通過對市電、自我發電和儲能設備的協調管理，確保了社區的穩定供電，同時降低了能源成本。 本研究的結論指出，推廣再生能源應用和加強儲能技術研發是未來的發展方向。政府和企業應加大對儲能技術的研發投入，提高儲能設備的效率和安全性。同時，制定和完善相關政策法規，推動智慧能源管理系統的建設，鼓勵企業和居民安裝和使用BEMS。通過社會宣傳與教育，提高公眾對再生能源和智慧能源管理系統的認識和接受度，促進全民節能減排意識的提高。 總之，本研究通過對兩個具代表性案例的分析，揭示了再生能源與儲能系統在微電網中的整合應用的可行性和經濟效益。希望本研究的成果能夠為相關領域的研究和實踐提供參考，推動再生能源和智慧能源管理系統的廣泛應用，實現能源的可持續發展。 關鍵詞：再生能源、太陽能光電、儲能設備、微電網、節能減碳

This study explores the integration of renewable energy and energy storage systems in microgrids, focusing on two typical cases: Penghu's Tongpan Island and the Xinglong D2 social housing district in Wenshan District, Taipei. The primary aim is to analyze suitable microgrid types, main renewable energy sources, and optimal energy storage system capacities through case data and economic benefit evaluations. Tongpan Island serves as a typical example of an island microgrid, primarily relying on diesel generators for electricity, supplemented by solar photovoltaic (PV) systems and energy storage devices. The research results indicate that choosing solar PV systems as the renewable energy source is based on multiple factors including technical feasibility, economic benefits, environmental impact, and social acceptance. Although the island has abundant wind energy resources, solar PV systems offer advantages in terms of installation and maintenance, operational stability, and environmental impact. Evaluations using the Net Present Value (NPV) and Internal Rate of Return (IRR) methods show that despite high initial investments, the Tongpan Island microgrid system demonstrates good economic benefits. The case of the Xinglong D2 social housing district in Wenshan District, Taipei, shows that the application of community microgrids in urban settings can effectively enhance energy utilization efficiency and reduce dependence on municipal electricity. This case involves the installation of a 10KW solar PV system and a 48KWH energy storage device, combined with a Building Energy Management System (BEMS), achieving effective use of renewable energy and emergency power supply needs. Despite limitations in installation space and regulatory compliance, the community's energy storage capacity, although modest, can provide necessary power support during emergencies. The application of BEMS in microgrids holds significant importance. BEMS can monitor and manage community electricity consumption data, use smart algorithms for energy dispatching, and achieve efficient energy utilization. In this study, BEMS coordinates the management of municipal electricity, self-generation, and energy storage devices, ensuring stable power supply to the community while reducing energy costs. The study concludes that promoting the application of renewable energy and enhancing energy storage technology development are future development directions. Governments and enterprises should increase investment in energy storage technology research and development to improve the efficiency and safety of storage devices. Simultaneously, relevant policies and regulations should be established and refined to promote the construction of smart energy management systems, encouraging businesses and residents to install and use BEMS. Through social advocacy and education, public awareness and acceptance of renewable energy and smart energy management systems can be improved, promoting increased awareness of energy conservation and emission reduction. In summary, this study, through the analysis of two representative cases, reveals the feasibility and economic benefits of integrating renewable energy and energy storage systems in microgrids. It is hoped that the results of this study can provide a reference for research and practice in related fields, promoting the widespread application of renewable energy and smart energy management systems to achieve sustainable energy development.
