Low‐voltage ride‐through control for photovoltaic generation in the low‐voltage distribution network [PDF]
IET Renewable Power Generation, 2020 The increasing penetration of photovoltaic (PV) energy in power grids will impose system instability issues, especially in the occurrence of faults. However, very limited research has been conducted on the low‐voltage ride‐through (LVRT) control of PV systems in the low‐voltage distribution networks (LVDNs) with predominantly resistive line impedances.

Low voltage ride-through of single-phase transformerless photovoltaic inverters [PDF]
2013 IEEE Energy Conversion Congress and Exposition, 2013 Transformerless photovoltaic (PV) inverters are going to be more widely adopted in order to achieve high efficiency, as the penetration level of PV systems is continuously booming. However, problems may arise in highly PV-integrated distribution systems. For example, a sudden stoppage of all PV systems due to anti-islanding protection may contribute to

Application of UPFC to improve the low-voltage-ride-through capability of DFIG [PDF]
2015 IEEE 24th International Symposium on Industrial Electronics (ISIE), 2015 In this paper, a new controller approach for unified power flow controller (UPFC) is proposed to improve the low-voltage-ride-through (LVRT) capability of a DFIG-based WECS during voltage sag. The shunt and series converters of the UPFC are controlled using a hysteresis current controller (HCC) and proportional integral controllers (PI), respectively ...

Design of a Microgrid with Low-Voltage Ride-Through Capability and Simulation Experiment [PDF]
Journal of Applied Mathematics, 2014 A microgrid with low-voltage ride-through capability is designed. The designed microgrid avoids operating in unplanned islanded mode during an asymmetric ground fault which occurs in the low voltage distribution network and supports fault recovery for distribution network.

A STATCOM with Supercapacitors for Low-Voltage Ride-Through in Fixed-Speed Wind Turbines [PDF]
Energies, 2014 Fixed-speed wind generator (FSWG) technology has an important presence in countries where wind energy started to be developed more than a decade ago. This type of technology cannot be directly adapted to the grid codes, for example those requirements related to the immunity level under voltage dips.
