碩士 === 國立臺灣海洋大學 === 電機工程學系 === 99 === The main purpose of this thesis is to discuss the effects of contingencies on the clustering of generators in power system coherency.The swing curves of generators under normal operation, N-1 contingencies,and N-2 contingencies are simulated and base on the similarity between swing curves and the method of hierarchical clustering analysis, generator coherent groups are identified for analyzing the effects of contingencies. This thesis is organized as follows: Chapter 1 is an introduction, Chapter 2 discusses the method of cluster analysis and power system coherency, Chapter 3 shows the results of a real power system, and Chapter 4 conclued the work of this thesis.
