Traditionally, rotating machines in the bulk power system have provided enough inertia to result in fault currents that are more than five or six times nominal current. Typical circuit protection schemes are designed to act on this high and long lasting fault current. However, with the growing trend of increased penetration of renewable energy, energy storage and microgrids, power electronic based systems are becoming more widely utilized on the grid. In heavily inverter-based power systems, the difference between nominal currents and short circuit fault currents is minimal due to reduced system inertia which altogether makes fault detection difficult. In this research, a model-based approach that utilizes the assumed dynamics of a grid-...
