本論文主要目的在研究微型電網之動態行為。首先,以Matlab/Simulink模擬軟體建立多種分散型能源之等效電路模型,所考慮之多種分散型能源包含小型風力發電系統模型、柴油發電系統模型及可控直流-交流功率轉換器模型;並針對台灣地區最為廣泛採用的輻射型配電系統規劃、建構一模擬用微型電網模型。接著,本論文透過嚴謹的模擬與分析,探究在多種分散型能源交互變動與作用下,其對微型電網系統頻率與各母線電壓所造成之影響,並分別針對併網運轉模式與孤島運轉模式,探求輻射型配電系統最適切之微型電網規劃與設計,期進而達到減少衝擊、提高電力品質等目標。


The major purpose of this thesis is to investigate the dynamic behavior in a Microgrid. First of all, various distributed energy resources (DERs) models including small wind generation systems, diesel generation systems and controllable inverters were developed by using Matlab/Simulink. In addition, a configuration of microgrid will be arranged and proposed for a practical radial distribution feeder in Taiwan. In this thesis, the variations in the system frequency and bus voltages are simulated in a rigorous way by considering the variations of interaction among the DERs installed. Hence, the most suitable microgrid configuration can be obtained and the objectives of lessening impact and improving power quality during both parallel operation and islanding modes can be achieved as well.
