本論文研究主要探討包含風力發電及柴油發電機組之獨立電力系統的暫態運轉分析與最佳經濟調度。首先介紹不同種類的風力發電機和穩定度，然後分別說明暫態穩定度(Transient Stability)分析流程與基因演算法(GA)之概念；選擇並建立金門電力系統架構，探討於風速劇變狀態和遭遇N-1 發電機跳脫事故後對整個電網造成的擾動，討論其暫態穩定度。考慮是否符合運轉限制條件及系統安全運轉
穩定度之要求，利用實數基因演算法(RGA)找尋兼具經濟調度考量之一日機組排程，以獲得具備選擇機組運轉的準確性與實際執行調度之可行性的最佳化經濟調度。

The objective of this thesis is to investigate the transient response and optimal economic dispatch of an isolated power system with wind generators. Different types of wind turbines and the classification of Stability are introduced. Then, the process of Transient stability analysis and the concept of Genetic Algorithms are given for explanation. In this thesis, the practical power system of Kinmen is selected for case study. The disturbances introduced by gusting wind and N-1 system contingency are considered in the transient stability analysis. Furthermore, in order to obtain both
accuracy and feasibility of the Optimal power dispatch by using Real-parameter Genetic Algorithms, the simulation results should be tested for the restrictions and requirements of the actual operation.
