Low Voltage Ride Through Characteristics of Grid Forming inverters
2020 21st International Scientific Conference on Electric Power Engineering (EPE), 2020With 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.

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 ...

2017 19th European Conference on Power Electronics and Applications (EPE'17 ECCE Europe), 2017
The total real power injected by distributed renewable energy sources (RES) in the low voltage (LV) grids can cause voltage rise effects during light load scenarios. Integrating RES in microgrid architectures can result in improved power quality of the electrical grid, by avoiding the voltage rise effect from occurring and also by providing ancillary ...

Testing Low Voltage Ride Through capabilities of solar inverters
Electric Power Systems Research, 2013Abstract The increase in the rated power of PV inverters has brought with it new requirements, such as Low Voltage Ride Through and reactive power compensation. Field tests in PV plants are too expensive in terms of production losses, and therefore laboratory tests have become a simple, flexible and inexpensive alternative.

Comparison of several Low Voltage Ride Through Attached Equipment
2019 IEEE 8th International Conference on Advanced Power System Automation and Protection (APAP), 2019The power plant auxiliary drive system will work abnormally or even trip due to frequency converter voltage drops, which might be caused by transient state process of auxiliary power system or the external grid. Low voltage ride through (LVRT) is an effective way to solve the above problem.
