摘要:	隨著全球能源危機和環境問題日益嚴重，分散式發電和微電網技術越來越受關注，發展再生能源，邁向低碳社會，已是無可避免的趨勢，因此未來的電力系統，勢必要降低石化能源比例，擴大再生能源利用。但由於大部分分散式電源通過逆變器等電力電子設備接入大電網，幾乎不具有慣量，當分散式電源的容量增長到占大電網一定比例之後，分散式電源的無慣量特性會給大電網的穩定性造成威脅。因此若能有效整合微電網電力控制策略與相關電力品質穩定機制，必將大大的提高微電網的安全穩定性。本計畫主要目標為(1)分析國內外配電系統擾動與故障案例；(2)提出配電網發送至微電網之調度命令與通訊格式規劃；(3)探討配電系統受再生能源等不同擾動與系統故障時，提出微電網分散式電源之漸進式輔助調控策略邏輯；(4)建構微電網模型，並以即時模擬驗證所提之漸進式輔助調控策略邏輯；(5)應用在核能所即時模擬系統OPAL-RT進行前述模型實測。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。 ;With the global energy crisis and serious environmental problems, distributed generation and microgrid technology have drawn much attention. Development of renewable energy towards a low carbon society is an inevitable trend. Therefore, the future power system is bound to reduce the proportion of petrochemical energy and expand the utilization of renewable energy. However, since most of the distributed generations are connected to the power system through power electronic equipment such as inverters, these systems almost have no inertia. When the capacity of the distributed generations increases to a certain proportion of the power system, the inertia-free characteristics of the distributed generations would introduce the threat to the stability of power system. Therefore, if the power control strategy and related power-quality stabilization mechanisms can be effectively integrated, the security and stability of the microgrid can be greatly improved. The main objective of this project is to (1) analyze the international case studies for disturbances and faults of distribution system, (2) propose the dispatch commands and communication formats for the distribution system and microgrid, (3) propose the progressive auxiliary regulation technique for multiple distributed generations in the distribution system under different disturbances and faults of renewable energy, (4) build up the real-time simulation model for the performance verification of proposed progressive auxiliary regulation technique, (5) apply the OPAL-RT real-time simulator in the institute of Nuclear Energy Research (INER) to examine the developed models. Besides, the microgrid system of the INER is adopted to establish the simulation models. Based on this system and real-time simulator, the regulation strategy of the distributed generators in different operating modes would be discussed to maintain the stability of the microgrid system.
