Steady State Voltage Rise and Its Control in Distribution System with Distributed Generation

Abstract

The continued interest in the use of distributed generation in recent years is leading to the growth in number of distributed generators connected to distribution networks. Steady state voltage rise resulting from the connection of these generators can be a major obstacle to their connection at lower voltage levels. The present electric distribution network is designed to keep the customer voltage within tolerance limit. Thus distribution network operators (DNO) need proper voltage regulation method to allow the significant integration of distributed generation systems to existing network. The aim of this paper is to examine the voltage rise problem in practical radial feeder and present the conventional and emerging developments in steady state voltage regulation methods used for distribution network with distributed generation (DG) system.
