Low Voltage Ride Through (LVRT) Constrained Transient Stability Assessment Using Lyapunov Functions Family Method [PDF]
2020 IEEE Power & Energy Society General Meeting (PESGM), 2020 Growing penetration of renewable generation in power systems brings more challenges in transient stability assessment using direct methods. One of the reasons is the inability to assess the risk of instability brought by tripping of a large amount of RGs due to violation of their ride through curves. In this paper, a scalable approach is proposed based

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 ...
