摘要:	由於再生能源與微電網建置之增加，使得穩定電力控制、能源最佳管理、互聯電網電力調度等議題逐漸受到重視。當大量的再生能源併入配電網後衍生之電壓變動問題將影響區域電網之供電穩定性與安全，此乃自然能之間歇特性導致再生能源發電設施之輸出電力產生變動以及系統中能源設施失衡的安裝設置所造成。不當的能源配置與電力調度策略會造成互聯電網系統在傳輸的過程中額外的損失，而控制響應性能不足的電力調控易形成微電網跳脫或減短電力設備的使用壽命。因此，提升系統控制時抗電力品質干擾能力及最佳化能源管理與調度，已逐漸成為電力公司與用戶間所關心的議題。本計畫主要目標為(1)建立含再生能源之配電網即時模擬模型;(2)提出配電系統對多個分散式能源系統之協調調度策略;(3)分析國際上應用調頻、即時與補充備轉容量的適用案例;(4)參考國際上配電系統擾動與故障情境，提出配電系統之調度命令格式;(5)利用即時模擬方式開發配電管理系統之輔助調控策略。此外，本計畫將依據核能所微電網系統為基礎，建立相關配電網模型，並透過即時模擬系統探討分散式電源在不同運作模式與情境之調控策略以維護微電網系統之穩定性。 ;Due to the widespread use of renewable energy and microgrids, the issues associated with stable power control, optimal energy management, power dispatch of interconnected microgrids have been of great concerns. With the large amount of renewable energy integrated into the distribution grid, various voltage problems affect the system stability and safety may be caused. This is due to the intermittent characteristics of natural energy which causes the output power variation on the renewable energy facilities and unbalanced installations of renewable power generations. The unsuitable energy arrangement and power dispatch strategy may introduce the additional power loss for the interconnected microgrids, and the insufficient performance of control response would easily lead to the tripping of microgrid and reduce the usage life of the power system equipments. Therefore, improving the robustness to power quality in system control and optimization of energy management and dispatch has become an important issue for both utilities and customers. The main objective of this project is to (1) build up the real-time simulation model for the distribution system with the renewable energy, (2) propose the power-regulation strategy for multiple distributed generations in the distribution system, (3) analyze the international case studies for regulation reserve, spinning reserve, and supplemental reserve, (4) propose the dispatch commands for the distribution system by considering the system disturbances and faults, (5) develop the regulation control strategy with real-time simulation. Besides, the microgrid system of the institute of Nuclear Energy Research (INER) is adopted to establish the simulation models. Based on this system, the regulation and transfer strategy of the distributed generators in different operating modes would be discussed to maintain the stability of the microgrid system.
