Voltage Sags in Photovoltaic Systems

Category: PQ Theory, Distributed Generation

Photovoltaic (PV) generation is electrically in parallel with the utility supply, and thus lowers the steady-state system impedance. The ideal result is a reduction in locally caused voltage sags as the PV system supplies power to high-current loads. The actual result can be an increase in voltage sag severity, due to the design of typical PV inverters. The reasons for this unfortunate result are presented here, along with a real-world example.....Download to continue reading!
