It　proposes　a　promising　power　flow　analysis　method　for　radial　distribution　system　with　distributed　generations(DGs),　combined　with　reactive　power　compensation　facilities.　In　the　power　flow　analysis,　suitable　models　are　determined　for　different　DG　units　,Q-sources　including　Static　Var　Compensator,　Switched　Capacitor　or　Shunt　Capacitor　and　Step　Voltage　Regulator.　A　helpful　method　is　presented　to　deal　with　the　PV　node,　static　voltage　control　model　node　and　PI　node　during　the　power　flow　iteration,　which　makes　Backward/Forward　Sweeps　technique　suitable　to　calculate　radial　distributed　system　power　flow　with　multiple　node　styles.　Then　an　example　of　28-node　radial　distribution　system　with　DGs　is　performed　to　validate　the　method　proposed　in　this　paper.　In　addition,　the　simulation　results　show　that　DGs　influence　on　voltage　profile,　power　losses　and　voltage　regulator　operating　status　greatly.　©2010　IEEE.
