In distribution systems, network reconfiguration is comprehended by changing the best possible status of placing the sectionalizing switches. It is generally performed for reducing the losses or for balancing the load in the system. Generally for the distribution systems, meshed networks are configured in a feeble manner with manifold supply points, but they are controlled with radial configurations by unbolting the redundant branches. The system should be recompensed, otherwise it creates disturbance which lead to variation in supply voltages. In this paper, a study related to network reconfiguration techniques is presented in order to avoid network congestion showing the importance of FACTS devices along with an overview of issues related to voltage collapses in distribution system.
