For the protection of power system, Directional Overcurrent Relays (DOCRS) are generally used as an economical means for protection in sub-transmission and distribution systems. Thus, it is required that relay has minimum operating time on the occurrence of fault keeping the operation coordinated with other relays. In our paper, a comparative analysis for optimal overcurrent relay coordination based on different metaheuristic techniques such as Genetic Algorithm (GA), Particle Swarm Optimization (PSO), Cuckoo Search Algorithm (CSA), and Firefly Algorithm (FFA) is analyzed. The various heuristic techniques are executed on different number of relays for constrained systems and the method which gives the operating time with minimum iterations and time is found.
