Islanding Detection with Reduced Non-Detection Zones and Restoration by Reconfiguration

The development and use of PV (Photovoltaic), Wind, Hydro-based Distributed Generation (DG) is presently on the rise worldwide for improving stability reliability, reducing power loss in distribution system with reduced emission harmful gases. A crucial issue addressed this article, due to increased penetration DGs, islanding operations. detection performed by a proposed v&f (voltage frequency) index method. reliability indices IEEE-33 118 radial bus after method evaluated considering as customer interruption. To mitigate islanding, reconfiguration strategy using Particle Swarm Optimization (PSO) also conventional system.
