Distributed Generation connection of converters to a low and medium power dc network using an inductor circuit

Abstract

. Small-scale distributed generators connected tothe low voltage network are generally operated with unity power factor. However, controlling their reactive power injection would have an impact on the voltage at their connection point, if the network is sufficiently weak and inductive. The purpose of this paper is to investigate how a small-scale distributed generator connected to a low voltage network through a power electronic converter can be controlled to improve the voltage quality at its connection point.
