With the rapid increase in energy demand all over the world and great advancements in technology, utilities are more interested in Distributed Generation (DG). Among different sources, synchronous and induction machines are widely used for DG applications. In this paper, a detailed performance evaluation is carried out for induction and synchronous machines in Distributed Generation mode. A typical radial distribution feeder is simulated in Electrical Transient Analyzer Program (ETAP) and the impacts of aforementioned sources are analyzed on DG. On the basis of comparison between sources, some basic technical factors such as voltage profile and electrical power losses are considered. It was found that the most desirable source depends on the characteristics of the distribution network, i.e. the core technical factors that might put constraints on the penetration level of DG.
