Low voltage fault ride through control in MMC-HVDC

2017 IEEE 26th International Symposium on Industrial Electronics (ISIE), 2017
Modular multilevel converters (MMCs) are the latest converter topology for the high voltage high power applications like the high voltage dc (HVDC) transmission. This paper presents the response of an MMC-HVDC converter during grid faults. Recent grid code requirements specify reactive current injection during low voltage fault conditions and negative ...

Mode switching DFIG for low voltage ride through

8th International Conference on Power Electronics - ECCE Asia, 2011
With 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 Characteristics of Grid Forming inverters

2020 21st International Scientific Conference on Electric Power Engineering (EPE), 2020
With the certainty of the high share of power electronics in power grid, algorithms for various grid forming inverters have emerged in academia. Due to the grid synchronization strategy of the grid forming inverter is completely different from the current grid following inverters, its dynamic characteristics during grid faults are also different.

Comparison of some low voltage ride-through strategies

IECON 2017 - 43rd Annual Conference of the IEEE Industrial Electronics Society, 2017
PV 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.
