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.
