An Optimization-based Protection Strategy in Active Distribution Network using Double Dual-Setting Directional Overcurrent Relays to Increase DG Penetration [PDF]
International Journal of Research and Technology in Electrical Industry, 2023 Coordination between protection devices is one of the important issues in any protection scheme of an electrical power system. The tendency to increasingly use distributed generation has jeopardized the selectivity of overcurrent relays in active ...

An Adaptive Overcurrent Coordination Scheme Withstanding Active Network Operations
IEEE Access, 2022 This paper aims to present a centralized adaptive protection scheme (APS) for the directional overcurrent relays (DOCRs) considering system dynamics such as load demand variations, topology changes and DGs to mitigate the above-mentioned effects.
