Low Voltage Ride-Through of Two-Stage Grid-Connected Photovoltaic Systems Through the Inherent Linear Power-Voltage Characteristic [PDF]
, 2017 In this paper, a cost-effective control scheme for two-stage grid-connected PhotoVoltaic (PV) systems in Low Voltage Ride-Through (LVRT) operation is proposed. In the case of LVRT, the active power injection by PV panels should be limited to prevent from

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

Low Voltage Ride Through einer synchrongeneratorbasierten Windkraftanlage
, 2022 Due to the increased power penetration level of wind energy, wind turbines are now system-relevant components of the power supply. To ensure grid stability, especially during a symmetrical or asymmetrical voltage dip, wind turbines must provide low voltage ride through (LVRT) capability with simultaneous dynamic voltage support ability by feeding ...

Comparison of current-limiting strategies during fault ride-through of inverters to prevent latch-up and wind-up [PDF]
, 2013 Transient stability of a power network requires that generators remain synchronized and return to normal power export once a fault is cleared. For inverter-interfaced generators, one must ensure that current and voltage limiters do not latch-up and that ...
