增加配電系統中分散式電源的併聯容量時，視其輸出大小與併聯位置和採用的電壓控制策略，會造成不等程度之過電壓或低電壓的情況。本論文介紹典型的電壓控制策略，並提出建議方案，以期增加分散式電源的併聯容量。本研究運用機率負載潮流的方法，展現各控制策略於分散式電源與負載變動之控制效能，而該效能以電壓變動改善指標與超限風險評估的方法來比較。

With increasing level of distributed generation（DG）on radial feeders in electric distribution systems, it could cause over-voltages as well as under-voltages depending on several factors including DG capacity, locations, and the strategy of voltage regulation. This thesis describes the typical and proposed voltage control strategies that could allow the increase of DG interconnection capacity. By using probabilistic load flow technique, voltage regulation performance for cases with different levels of DG outputs, demands and voltage control strategies are presented. They are compared by using a voltage profile improvement index and a risk assessment technique.
