Abstract: The increasing penetration of new energy into the power system is accompanied by a series of challenges that traditional relay protection systems face: fast fault detection and decreased protection action time, and decreased system stability. Redefining relay protection systems is essential for power grids to reliably integrate surging renewable energy sources. Relay protection is designed to detect abnormal conditions, such as faults, and isolate the affected part of the system to prevent damage to equipment.
