Abstract
Connecting Distributed Generators (DGs) into conventional distribution systems leads the protection design assumptions to become incorrect. These generators are commonly utilized with renewable energy resources including solar photovoltaic (PV) and wind electric conversion systems (WECS). A part of this study presents a practical and versatile setting profile for overcurrent protective elements in such networks that have considerable amounts of DG units. For this target, a typical 11 kV underground distribution feeder is modeled while a considerable DG unit is inserted. Different locations and sizes are considered for the utilized DG. This part of study assists to realize better protection coordination, lower fault clearing times with the existence of DG units.
