摘要

本國電力事業公司採用偶發備轉容量以因應偶發事故，確保系統之可靠性及維繫系統頻率之穩定性。備載排程的指導方針總是具體指定備轉機組數量及響應速度應該符合於一些特定的水準。本論文呈現一套演算法以線上即時估測獨立電力系統之頻率響應特性值（ ），此估測之 值能有效地應用於備轉容量之規劃更新排程。本文所提議偶發備轉容量之規劃係針對一序列的系統頻率恢復過程，配置合適的機組以符合相對應的備載量及升載率要求並確保備轉反應之有效性。在模擬條件及實際運轉資料之比較下可驗證其規劃方法之可行性，此方法有助於電力調度中心提升偶發事故負載頻率控制之效能；且在未來電業解制後，可成為電力備載市場輔助服務配置備載規則之重要參考法則。

Abstract

Utilities use contingency reserve to deal with the contingency events, to ensure that the reliability and frequency support are well maintained, the reserve scheduling guidelines always specify that the reserve quantity and response rate should meet some specific levels. This thesis presents an algorithm to estimate frequency response characteristic, , of an isolated system online. The real-time estimated could be gainfully used for the instant when the update of reserve scheduling is needed. A contingency reserve scheduling according to a series of frequency restoration process is also proposed to ensure the effectiveness of the reserve response. Results showing that the feasibility of the scheduling method in simulated condition and on actual operating data are examined. The proposed method is beneficial for dispatch center to enhance load frequency control performance of reserve operation. It also can be deemed to be important operating paradigm for the reserve ancillary service in the deregulated utility industry.
