Micro-Grid Relay Coordination Using ETAP

The uninterrupted electrical power system must be set up to be safe, stable and reliable for the contemporary power system. The IEEE 9-Bus Micro-Grid System is examined in this article for coordination protection based on load flow and short circuit analysis and the development of an over current relay method to effectively manage the relay and immediately separate the faulty section from the faulty section. The behavior of the current defense strategy should be studied to build this electrical system. The authors of this article use ETAP simulation to model the IEEE 9-Bus based Micro-Grid system and use relay coordination to analyze the results. Research results show that the behavior of the Micro-Grid system when three phase fault occurs on different buses having the different renewable energy sources used in the bus system. In the given paper the protection scheme is furnished with the overcurrent relay is tested using ETAP on a micro-grid having multiple renewable sources like wind turbine, solar panel and diesel generator at several fault locations.
