Protection of Inverter Based Distributed Generation During Faults

Distributed generation (DG) can possibly enhance conveyance framework execution. The utilization of DG emphatically adds to a perfect, clean, reliable and financially savvy vitality for future. A standout amongst the most important technical viewpoints in micro grid framework is distribution system protection. Because of the low magnitude of short circuit currents produced by inverter based distribution generation, customary assurance methods which hand-off on current (fuses and over current relays) may neglected to protect such networks. In this research article, we investigate the problem of fault protection and overcurrent protection strategy in a microgrid containing inverter-based distributed generators using the "rate of change of current (ROCOC)" technique. Simulation of the proposed system has been carried out to verify the feasibility of the work done."
