Abstract: 
The thesis investigates on photovoltaic (PV) system equipped with grid-connected three-phase inverter under low-voltage AC (LVAC) microgrid, focusing on ground faults under different conditions such as line-to-ground faults, double-line-to-ground faults, and triple-line-to-ground faults with resistance-free, resistance, resistancecapacitance, and resistance-inductance scenarios. Three real-time monitoring and fault detection techniques, namely Base, Transient Monitoring Function, and Phase-AngleShift and D Parameter (PAS&Dpara), are proposed to address the issues. The primary goal of the research is to gather and examine abnormal behaviors of fault types and assess the performance of these algorithms in fault detection scenarios, thus recommending the precise and reliable ways to spot the ground fault in the power
system.
