On the Development of Overcurrent Relay Optimization Problem for Active Distribution Networks

The goal of this review paper will be to address complex optimization functions in the area overcurrent relay optimization, inspect and valorize their objectives critically examine application real distribution networks. Special emphasis put on observing discrimination time between primary backup pairs, methods which prevent latter becoming penalty shown. Furthermore, impact distributed generation units problem elaborated detail. Protection settings all existing new relays must thoroughly inspected before connection production units, because contributing fault currents may have a significant effect solution problem. This is being used are an inverse-type. Next, meshed network operation assessed comparison with actual practice radial operation, some topologies highlighted for future research, while others discarded. mesh implicitly suggests using numerical both sides protected elements (usually lines), so total number much higher than operation. Finally, relatively concept adaptive protection reviewed, its potential examined. purpose lay groundwork research papers by inspecting overall development contemporary active
