Study of voltage profile of a distributed generation system

Abstract

An IEEE 34 node test feeder is constructed by using DIgSILENTPowerFactory. The load flow results are more or less as given by IEEE. Dynamic and static photovoltaic system, dynamic and static wind generator are modeled. Distributed generators are modeled in the setting in a way, such that load flow calculations can be carried out when they are interfaced to IEEE 34 node test feeders system. Different settings and locations are selected in order to observe the impacts on voltage profile. After distributed generators have been added, load flow results have shown improvement in voltage profiles. Hence, power losses have been reduced.
