- © 2021 IEEEDirectional Overcurrent Relays (DOCRs) optimization problem has always been an important task for sub-transmission and distribution protection that constitutes a non-linear and highly constrained optimization problem. This paper aims at implementation of an easy and effective EVOlutionary Algorithm of Random Variables with NORMal Distributions (Evonorm) for solving the DOCRs coordination problem. The proposed algorithm has been applied to a highly meshed 6-bus system. Results have shown that the proposed algorithm can effectively handle the complex DOCRs coordination problem.
