Protection coordination of directional over current relay with distributed generation
Indonesian Journal of Electrical Engineering and Computer Science, 2022 The present <span lang="EN-US">study is focussed on a comparative analysis of different meta-heuristic optimization approaches for directional overcurrent relay (DOCRs) coordination which has been discussed and presented in the literature. Further, to have a comparative analysis of the performance of the optimization methods discussed they have ...

Coordination of Over Current Relays in Distributed Generation
International Journal of Recent Technology and Engineering (IJRTE), 2019 The modern power system increases the power by adding Distributed Generation (DG). When distributed energy sources are added to the network, they effect the conventional fault levels and fault current paths and have been proved that the accurate operation of the overcurrent protection is not possible.
