One of the main protection methods in distribution systems is over-current protection. Although, over-current protection offers economic solution to the operators; optimal over-current coordination must be established between relays in order to provide fast and selective protection. Thus, over-current relay coordination problem can be constructed as an optimization problem with number of constraints. Meta-heuristic optimization algorithms have widely been employed to obtain better solution. Many optimization algorithms have been conducted by various researchers. Also introduce recently developed optimization algorithms that are applied on over-current relay coordination problem first time in the literature. In this study, performance analysis of different optimization algorithms is carried out by using sample test cases from the literature. Also two recently developed optimization algorithms are applied on over-current relay coordination problem.
