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 ...

Wind turbine level energy storage for low voltage ride through (LVRT) support
2014 IEEE Symposium on Power Electronics and Machines for Wind and Water Applications, 2014 Variable wind speed leads to variable wind power generation, voltage fluctuations, and frequency deviations, which are the main problems related to wind energy integration into a grid. These problems become more evident in weak grids. In addition, wind farms have to take the grid problems into consideration and have to provide support during grid ...
