AC/DC Fault-ride-through Control for Single-phase PV Inverter

Single-phase low-power PV generators will be a dominant contributor to electricity in microgrids. However, PV-inverters are susceptible to input and output disturbances. On the one hand, the inverters disconnect entirely for a few minutes during grid sags. On the other hand, the inverter's power output drops during low solar insolence, leading to grid voltage flickers. Moreover, the conventional l...
