The paper presents an approach to improve the reliability and reduce line losses of practical distribution system applying network reconfiguration. The change of the topology redirects the power flow within the distribution network to obtain better performance of the system. Practical distribution network (Pyigyitagon Industrial Zone (I)) is used as the case study network. The detailed calculations of the reliability indices are done by using analytical method and power flow calculation is performed by Newton-Rephason solver. The comparison of various network reconfiguration techniques are described with respect to power loss and reliability index levels. Finally, the optimal reconfigured network is selected among difference cases based on the two factors: the most reliable network and the least loss minimization.<\/p>\r\n","references":"[1]\tBillinton R., and Allan R.N., Reliability Evaluation of Power System, Plenum Publishing, New York, 2nd Edition, 1996.\r\n[2]\tBillinton, R., \"Distribution System Reliability Performance and Evaluation\", Electrical Power and Energy System, vol.10, no.3, July, 1988.\r\n[3]\tA.H.
