Abstract

The distribution systems were normally passive and it is designed to operate with unidirectional power flow. With integration of DG, the distribution system becomes an active system and bidirectional power flows should now be incorporated in the network design and its operation criteria. Studies on impact of DG on power flow, line loss, voltage profile and voltage stability requires suitable tools. The main aim of this paper is to determine the optimal placement of distributed generators so that net power saving are maximized and hence improvement in the voltage profile is achieved and hence the voltage stability is improved. A sample case study has been presented on practical agricultural radial distribution system to know the impact and system support benefits of distributed generators with the help of methods developed in the earlier using MATLAB software.
