Abstract: Optimal network reconfiguration significantly improves bus voltages and reduces overall active power losses. Numerous techniques for optimal network reconfiguration have been documented in the former studies. This article presents a strategy for optimal network reconfiguration designed to minimize overall active power losses in the standard IEEE 33- and 69-bus Radial Distribution Systems (RDSs). The proposed method, derived from the Marine Predators Algorithm (MPA), effectively identifies the optimal linking and isolating branches to be switched on and off to mitigate overall active losses. MPA is inspired by the foraging attitudes of ocean hunters, including Lévy and Brownian motions, as well as the most efficient encounter strategy observed in biological predator-prey relations. For both experimental systems, the proposed method outperformed other referenced techniques by achieving the lowest overall active power losses and enhancing bus voltages. Furthermore, a statistical study is conducted to confirm the proficiency of the suggested MPA approach.
