Low/Zero-Voltage Ride-Through Control Strategy of Single-Stage Grid-Connected PV Systems Based on Voltage–Current Joint Compensation

For single-stage grid-connected photovoltaic (PV) systems, severe low- and zero-voltage faults may cause synchronization instability and even the disconnection of large-scale PV inverters. To investigate this issue, a nonlinear large-signal dynamic model of a phase-locked loop (PLL)-based grid-connected PV system is es...
