ABSTRACT: Installation of Distributed Generator (DG) is a well accepted method to improve power system operation
from the point of reducing congestion and improving voltage profiles. For best
results, Distributed Generators should be placed at strategic locations to
exploit maximum benefits out of them. The (N-1) contingency criterion has been
taken into account in this work. Most congested lines of the grids are ranked
by congestion Index and considered to study the impact of DG penetration on congestion. The present paper proposes
contribution factors of Distributed Generators for the placement of DG to keep the line flow within the
capacity of each transmission line of the network. The results obtained from
IEEE 30-bus test system indicate that the proposed methods are capable of identifying
desirable DG location and its maximum
allowable size. The influence of DG on
bus voltage profile has also been demonstrated in this paper.
