Comparison of some low voltage ride-through strategies
IECON 2017 - 43rd Annual Conference of the IEEE Industrial Electronics Society, 2017PV system integration with power grid has many challenges. One of these challenges, the disconnection of PV inverters from the grid under grid faults; these disconnections lead to a stability problem in larger scale of PV power plant. This paper is focused on the comparison of some Low voltage ride-through strategies.

This paper describes a two-stage current limiting control strategy to improve the low-voltage ride-through capability of direct-droop-controlled, grid-forming inverters. When a low-voltage event occurs, the Stage 1 current limiting control rapidly clamps

Low-voltage ride-through simulation for microgrid systems
2017 IEEE International Conference on Electro Information Technology (EIT), 2017In contrast to the previous generation of power grid codes, recent standards require that distributed energy resources (DERs) provide low-voltage ride-through (LVRT) capabilities during grid faults. Consequently, the high penetration of DERs in today's power system requires an efficient method of controlling the active and reactive power of those ...

Low-Voltage-Ride-Through-Assistenzsystem für dezentrale Erzeugungseinheiten
e & i Elektrotechnik und Informationstechnik, 2014Wahrend eines Kurzschlusses im Netz nahe einem Synchrongenerator kommt es aufgrund einer verminderten Leistungsabgabe wahrend des Fehlers zu einer Beschleunigung des Rotors. Dies kann zu unerwunscht hohen Polradpendelungen bis hin zum Verlust des Synchronismus des Generators fuhren.

Mode switching DFIG for low voltage ride through
8th International Conference on Power Electronics - ECCE Asia, 2011With the rapid development of world-wide wind energy generation using doubly fed induction generations (DFIGs), low voltage ride through (LVRT) has become a great concern. This paper focuses on a unique topology of DFIG called IG connection mode to help the DFIG ride through grid faults smoothly.

Low Voltage Ride Through einer synchrongeneratorbasierten Windkraftanlage
2022Due 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 ...

Effect of low voltage ride through (LVRT) characteristic on voltage stability
IEEE Power Engineering Society General Meeting, 2005, 2005The number of wind installations has grown worldwide at unprecedented rates in recent years. As well, the average size of the installations has increased due to the advent of larger capacity machine, variable speed technology, and an increasing number of off-shore sites.
