Energy Science &Engineering, Volume 14, Issue 1, Page 377-398, January 2026.Standard and proposed non‐standard OCR characteristics. ABSTRACT This study introduces an advanced adaptive protection approach for AC power systems, designed to address key limitations in current clustering‐based relay coordination methods. Using K‐means, hierarchical, and spectral clustering techniques, the proposed scheme classifies grid operating ...

Modelling of Secondary Arc Using EMTP-RV [PDF]
The Transactions of The Korean Institute of Electrical Engineers, 2012 Most of faults occurred in transmission lines are single-phase to ground faults and transient faults. Single-phase auto reclosing is an appropriate scheme to maintain the system stability and restore the system effectively when those faults are occurred.

An Efficient Hybrid Islanding Detection Method for Microgrids Using Kalman Filter
Engineering Reports, Volume 7, Issue 12, December 2025.Islanding condition gives rise to several problems in distributed generation networks, including power quality disturbances, equipment damage, interference with grid protection, and danger to the utility crews. To avoid islanding detection failure of the passive section in case of a close matching between islanded generation units and loads, the active
