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.

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 ...

Active Power Control of Hydraulic Wind Turbines during Low Voltage Ride-Through (LVRT) Based on Hierarchical Control [PDF]
Energies, 2019 To improve the power grid adaptability and low voltage ride-through (LVRT) capability of hydraulic wind turbines (HWT), an LVRT control method based on hierarchical control is proposed for the energy regulation of HWT. The method includes a top-level machine-controlled paddle, mid-level control based on variable motor swash plate angle, and an ...
