The power loss in the radial distribution network is
appreciable as compared to transmission network. To reduce the
power loss in distribution network which is radial in nature, the
solution methodology adopted in this paper is optimal placement
of distributed generators (DG). The optimization incorporated is
Multi-objective Grey Wolf Optimization (MOGWO). The
optimization is accomplished for three different cases. In each
case two objective functions are simultaneously optimized to
obtain non-dominated solutions using Multi-objective Grey Wolf
Optimization. Case (1): To minimize the real power loss and
maximize the savings obtained due to DG installation. Case (2):
To minimize real power loss and maximum voltage deviation in
the network. Case (3): To minimize real power loss and rating of
DG installed. MOGWO method maintains an archive which
contains pareto-optimal solutions. The archive mimics the
behaviour of grey wolves. MOGWO method is verified on radial
distribution networks. The effectiveness of the optimization
method is proven by comparing the results with other optimization
methods available in the literature.
