Optimal Overcurrent Relay Coordination in Distribution Networks
2021 56th International Universities Power Engineering Conference (UPEC), 2021 Over-current relay coordination plays a critical role for effective protection of networks since primary protection is based on over-current detection in distribution systems. Thus, optimal relay coordination must be ensured between relays in faulted condition, providing selectivity and fast operation.
