Abstract
This study investigates the safety coordination of overcurrent relays (OCRs) in a distributed network, considering its diverse operational modes. Two distinct case studies are explored, specifically: (i) a distribution network integrated with distributed technology (DG) in grid-related mode, and (ii) a distribution system included with DG in islanded running mode. A proposed approach is evaluated the use of the distribution network, comprising 9 buses. Upon fault incidence, changes in fault current degrees without delay impact OCR working times. Consequently, it's far crucial to decide and advise optimized relay settings to reduce working instances and prevent maloperation. In this research, a protection scheme is optimally designed by way of thinking about those aforementioned conditions. Decreasing OCR working instances and keeping coordination are executed via figuring out most suitable time dial placing (TDS) values. The Genetic Algorithm (GA) is applied to decide those highest quality TDS values, thereby impacting OCR working times.
