The Hybridization of PSO for the Optimal Coordination of Directional Overcurrent Protection Relays of the IEEE Bus System

The hybridization of PSO for the Optimal Coordination Directional Overcurrent Protection Relays (DOPR) IEEE bus system proposes a new method coordinating directional overcurrent protection relays in power systems. combines hybrid particle swarm optimization (HPSO) algorithm and heuristic to find minimum total operating time with speed accuracy. proposed is tested on 4-bus, 6-bus, 8-bus systems, results are compared those obtained using traditional coordination methods. collected findings suggest that may produce better faster operation DOPRs than previous methods, an increase up 74.9% above technique. offers promising approach optimize protection.
