摘要
隨著大量的再生能源發電併入區域電網造成電壓浮動的問題,影響系統供電穩定度,國內外皆積極進行微電網相關技術研究,利用各種儲能電池、智慧電力電子裝置、及先進資通訊等控制技術,將區域電網內的分散式電源與負載進行整合,以提升微電網之電力品質與供電可靠度,若微電網技術應用於偏鄉,可發揮災區緊急供電與救難之功能;而應用於離島,亦可降低傳統機組的發電成本,具有其經濟效益。故本論文探討核能研究所微電網自主式運作之功能與成效,以及建立微電網之電力調度系統,並提出微電網彈性恢復控制設計,期可於台電緊急供電狀況下,接受台電配電調度中心進行需量控制,輔助電力系統運轉;且當配電系統發生異常時,微電網可進行孤島運轉,並藉由調度系統進行饋線轉供與併聯發電,協助台電系統快速恢復供電,提升配電系統供電可靠度為目標。

Microgrid is able to operate in grid-connect mode to provide surplus power generation to a distribution system. In cases of grid fault and interruption, the microgrid can isolate the fault and operate in standalone mode to maintain normal operation of distributed generators and loads. However, the microgrid may not be able to reconnect to the distribution system during performing load transfer of distribution feeders, and even cause outage of the distribution system due to synchronization problem. In this paper, the distribution automation system is designed by adding smart switches to achieve resilienct control of the microgrid. To verify the effectiveness of proposed method, the distribution feeders of the INER microgrid are selected to implement automatic generation transfer system. The reliability analysis is also performed to evaluate the unavailability of the INER microgrid. It is found that the outage time of loads in the microgrid with resiliency control can be significantly reduced.
