Application of Marine Predator Algorithm in Solving the Problem of Directional Overcurrent Relay in Electrical Power System

In electrical power systems, directional overcurrent relay (DOCR) coordination is assumed to be an essential component of the system for protection purposes. To diminish and reduce losses, between these relays ought kept at ideal value minimalize overall operating time all primary-relay shortcoming situations. The DOCR a complex profoundly compelling nonlinear problem. objective function total minimize inordinate breakdown interference. Coordination performed using marine predator algorithm (MPA), inspired by widespread foraging strategy, namely Lévy Brownian movements, search global optimal solutions in order resolve DOCRs issue. results acquired from MPA are equated with other state-of-the-art algorithms, it was observed that proposed outperforms algorithms.
