DOI: 10.1109/cjece.2018.2802461
Abstract: The optimal relay coordination (ORC) problem for directional overcurrent relays (DOCRs) has been solved by many conventional and modern optimization algorithms. All these studies were based on the common assumption that all DOCRs are numerical,… read more here.
