Normally consumers faced so many power interruption problems in the power distribution network. The distribution network is interrupted because of the power loss problems occurs in the power system. Network Reconfiguration (NR) is one of the major approaches for loss minimization to satisfy the customers demand by modifying the structure of distribution network. The main aim of the NR is to attain a radial network that optimizes the losses in the network and some other various techniques are utilized. In literature, various algorithms have been determined for network reconfiguration problems. In past years, the reliability in distribution network has been developed for uninterrupted power supply to the consumers. It presents a classical introduction, bibliographical review, and related analysis of methods utilized for reconfiguration of the system for loss reduction so that the scholars can quickly analyze the literature, particularly in this field. The current review mainly focusing on the conventional, novel techniques, optimization algorithms for reconfiguration and optimal allocation of distributed generation plays a significant part in enhancing the efficiency and precision of the results.
