Hybridization of PSO for the Optimal Coordination of Directional Overcurrent Protection Relays [PDF]

Electronics, 2022
In the electrical power system, the coordination of directional overcurrent protection relays (DOPR) plays a preeminent role in protecting the electrical power system with the help of primary and back up protection to keep the system vigorous and to avoid unnecessary interruption. The coordination between these relays should be pursued at optimal value
