Distribution networks are not perfectly balanced all time due to the nature of dynamic loads in the system. High energy demand due to variety of loads makes distribution system to be highly unbalanced. Unbalanced distribution systems have fluctuating voltage profile but we need flat voltage profile for smooth operation and loss minimization in our network. There are several techniques which have been proposed to improve the voltage profile of unbalanced distribution system. In this paper, various modelling techniques
and their applications have been examined. Also, voltage profile improvement technique for unbalanced distribution system is discussed. Effect of ZIP load model have also been seen on the proposed system. IEEE 13 bus radial distribution system is taken for study purpose
