摘要

為了確保系統運轉的安全及可靠，將充裕的緊急備轉容量分散至系統的不同機組上，有助於擁有大量風力發電之孤立系統於緊急事故發生時，較有能力反應頻率的變動及系統負載的快速提升。本文中，幾個技術性之限制條件係用以決定風力機發電容量可併入孤立系統之比例，而直接搜尋法則以最低發電成本用來協調風力與火力發電量的調度問題。實例中可瞭解各種不同限制條件對發電成本所造成的影響，可提供台灣電力公司調度與規劃的重要訊息。

To ensure the security and reliability of an isolated power system, and to maintain sufficient emergency reserves across several system units, a system with significant wind power generation, is much more capable of responding to frequency deviations and system load pick-up following a contingency. In this paper, several techniques are applied to determine the proportion of wind generator capacity that can be integrated into an isolated system. The direct search method is also extended to coordinate wind and thermal dispatch and to minimize total generation cost. Numerical experiments are included to demonstrate various constraints in production cost analysis and to provide valuable information for both operational and planning problems in the Taiwan power system.
