Distributed Generation is gaining popularity with the recent advancements in the renewable energy sources. DGs are used as a source of energy as well as performance enhancers by utilities. Subject to the weather of a certain location different DG sources are used in which Wind Turbines, Small Hydro Plants, Photovoltaic and Fuel Cells are commonly used. In this research work, a detailed comparative analysis is made among Wind Turbine, Photovoltaic and Synchronous machine to suggest the most suitable source. The said comparison is made on the technical factors such as voltage and electrical power losses and on the basis of this comparison a suitable DG source is suggested. A radial distribution feeder is simulated in Electrical Transient Analyzer Program (ETAP) to study the effect of these sources on the test distribution network
