    Abstract: 隨著能源成本的提高,各國紛紛祭出新能源政策,尋求替代能源,促使具有分散式電源的微電網系統逐漸受到重視。然而隨著微電網的大量佈建,分散式電源會導致系統一些影響,如保護協調、電壓調節、諧波和間諧波、電壓變動等供電穩定度問題。為了強化區域電網強健性,提供電力系統更具靈活性即時電力服務與可調度資源之技術,本計畫就智慧型交流微電網在分散式發電、儲能、能源調節與電力品質維護等技術方面進行整合與研發,以確保能源有效應用、改善負載管理、強化系統、與提升電力品質等目標。本計畫未來之主要研究關鍵技術包括:(1)電力品質調節-進行諧波、間諧波、電壓驟降、電壓驟升等電力品質污染改善;(2)頻率與電壓調節-進行系統運轉頻率與電壓穩定控制,增加再生能源併網率及微電網孤島運轉平穩性;(3)功率/需量調節-進行電力潮流調整,並依系統需求進行需量調節控制;(4)備援功能-進行系統基載電能需求供給,並於孤島模式下提供長期之運轉電源;(5)能源轉換效率調節-進行能源轉換效率提升;(6)輔助服務-進行交流微電網對市電系統之電力調節,提高分散式電源對系統之貢獻與附加價值。 ;With the raise of energy cost, every country proposes many strategies to search for alternative energy. This trend makes the microgrid system with distributed energy sources more attractive. With the massive deployment of microgrids, some undesired effects are accompanied with their installations and operations, such as protection coordination, voltage regulation, harmonics, interharmonics, and voltage fluctuation, etc. To enhance the robustness of microgird to provide flexible real-time power service and controllable resources, this project is focused on the integration and research of distributed generation, energy storage, power conditioning, and power quality for smart AC microgrid to make sure the efficiency of energy usage, load management, robustness of system, and enhancement of power quality.The key techniques of this project can be summarized, which include: (1) Power-quality regulation – improve the power quality disturbances such as harmonics, interharmonics, voltage sags, voltage swells, etc., (2) Frequency and voltage regulation – control the operation frequency and voltage of system to increase the grid-connected capacity of renewable energy and stability of microgrid in islanding operation, (3) Power and demand regulation – control the power flow and perform demand regulation according to system requirements, (4) Regulation of energy conversion efficiency – increase the energy conversion efficiency, (5) Auxiliary service – provide the power conditioning between AC microgrid and utility power system to enhance the contributions and additional value of distributed energy for utility power system.
