本論文研製一套應用於小型分散式發電之串聯模組。其概念為利用電壓源轉換器來注入不同大小與相位電壓，以達到能量輸出及壓降補償的目的。由於使用串聯併網的方式，將使能量儲存元件的輸出與線路負載量有著強烈的關係，可達成均載的作用。而在電壓驟降發生的情況下，串聯型併聯模組能輸出補償電壓，有效解決電壓降問題。本論文所提出的控制法乃採用電壓追蹤的方式，主要的工作為研製一單相484 VA之系統雛形來驗證本文所提方法之效能，本研究亦透過套裝軟體Matlab-simulink的模擬，比對模擬與實做之結果。

An implementation of a series interconnection scheme for small distributed generation systems is presented in this thesis. The concept uses one set of voltage source converter to control the injected voltage magnitude and phase angle for power injection and voltage sag mitigation. Because of the use of series interconnection scheme, the energy storage device outputs vary concurrently with the line loading and provides loading leveling functions. Under voltage sag situations, it provides missing voltage to effectively deal with power quality problems. The control algorithm uses the reference voltage tracking concept. A signal phase 484 VA prototype of the proposed system is implemented. The performance of the proposed method is simulated and verified by using Matlab-simulink package and the implemented module.
