本論文探討分散式電源於配電系統中的裝置點，經由目標函數以及系統損失來決定分散式電源在系統中之最佳安置點。文中利用電力系統之模擬軟體CYME來分析分散式發電系統與市電系統併聯運轉時，可能發生動態與穩態特性影響。本文以「IEEE 六個匯流排測試系統」和「實際台電系統」，探討其之間相互影響。在系統動態研究方面，本論文針對單台感應機分析故障發生時，對系統產生衝擊及影響。在系統穩態分析方面，本論文針對系統效率、責任分界點之電壓變動率、投入負載於系統、饋線上有無串聯電抗器以及改變變壓器分接頭電壓等級對系統特性之影響，做一併研究探討。
本文除了可提供分散式電源業者做為參考依據外，也可讓電力公司在執行配電系統運轉規劃時，改善供電品質與可靠度。

In this thesis, an objective function and the concept of system electric loss are first proposed to determine the optimal location to place a distributed generation (DG) source in a connected distribution system. This thesis employs a power system simulation program, CYME, to analyze dynamic and steady-state performance of dispersed generation systems connecting to an utility grid. The studied system contains an IEEE 6-bus test system and a practical Taiwan Power System. Dynamic characteristic of the studied induction generator under faulted condition are also examined. The steady-state results of the studied system under system efficiency, the percentage of voltage variation of point of common coupling (PCC), the system with and without loads, with and without series reactor in feeders, and changing the voltage level of tap changer of transformer are explored.
The results of the thesis can provide the planning and operating strategies for the dispersed generation systems (DGS) manufacturers. Furthermore, the utilities can improve the power quality and the reliability of the distribution.
