• This paper proposed a novel optimization technique derived from the crow search algorithm (CSA) for overcurrent (OC) relay coordination in mesh distribution networks. CSA is a meta-heuristic optimizer algorithm, influenced by the cleverness approach of crows. This algorithm can be treated easily by changing only two parameters like, flock size and iteration. In the present work an objective function (OF) is build up to work out the problems of relay coordination developed from time dial (TDS) setting and also the competence of the proposed technique is verified for four different power system networks and compared with existing techniques. Result and performances are the evidence that the suggested scheme is efficient, precise and simple.
