An improved low‐voltage ride‐through (LVRT) strategy for PV‐based grid connected inverter using instantaneous power theory [PDF]
IET Generation, Transmission & Distribution, 2020 Abstract This paper presents a low‐voltage ride‐through technique for large‐scale grid tied photovoltaic converters using instantaneous power theory. The control strategy, based on instantaneous power theory, can directly calculate the active and reactive component of currents using measured grid voltage and currents and generate ...

EnergiesSince the stator of DFIG-based wind turbines is directly connected to the grid, it is dramatically affected by transient situations that may occur on the grid side. In order to meet grid code requirements, reactive power support must be provided to keep the DFIG connected to the grid during the transient state. To achieve this, Low Voltage Ride Through

Adjustable unbalanced current controller for tranformerless PV generation to suppress DC voltage ripples of inverter in low‐voltage ride‐through (LVRT) operation [PDF]
IET Renewable Power Generation, 2022 Abstract Low voltage ride‐trough (LVRT) feature is compulsory for each grid‐connected inverter to support the grid by injecting reactive power in low voltage conditions. It is well known that the operation of an inverter in a normal grid condition is different from its operation in a faulty one.
