Low‐voltage ride‐through control for photovoltaic generation in the low‐voltage distribution network [PDF]

open access: yesIET Renewable Power Generation, 2020
The increasing penetration of photovoltaic (PV) energy in power grids will impose system instability issues, especially in the occurrence of faults. However, very limited research has been conducted on the low‐voltage ride‐through (LVRT) control of PV systems in the low‐voltage distribution networks (LVDNs) with predominantly resistive line impedances.
