Analysis of unbalanced distribution system voltage depedant load models with load growth

In this paper, the impact of models of voltage dependent loads have been discussed for the analysis of URDS (Unbalanced Radial Distribution Systems) for the future expansion of electrical distribution network. Load growth need to consider for better operation of the distribution system. Minimum voltage, system real and reactive power losses, number of iterations and CPU time are calculated with different load models including the load growth. The load flow analysis has been carried out using forward/backward sweep method. The results are validated for IEEE 19 and 25 bus URDS.
