With the remarkable increase in wind energy installed capacity, the wind energy conversion systems are also needed to be treated as conventional energy resources. These wind farms are required to be connected to grid as per grid codes during and as well as after the occurrence of short fault.

IEEE transactions on industrial electronics (1982. Print)
Grid-forming (GFM) inverters have the advantages of voltage and frequency support in weak grid. However, unlike grid-following inverters, GFM inverters present a more challenging picture during asymmetrical voltage sag.

System-Level Low-Voltage Ride-Through Control for the Renewable Power Plant Connecting to Weak Grid
IEEE transactions on industrial electronics (1982. Print)This study focuses on the low-voltage ride-through (LVRT) control in large-scale renewable power plants (RPPs) connected to weak grids, where grids fail to offer adequate reactive power, resulting in voltage fluctuations and necessitating additional ...

2015 IEEE Applied Power Electronics Conference and Exposition (APEC), 2015
This paper proposes a Doubly-Fed Induction Generator (DFIG) Wind Power System, which is driven by the novel Nine-Switch Converter (NSC). Considering the switches in the NSC are shared by two three-phase ports, a new adapted control method is proposed to flexibly control and fully use of the current capacity of the switches.

Sequential Dynamics in Photovoltaic Power Station Under Low Voltage Ride Through
IEEE transactions on energy conversionThe conventional simplification of a photovoltaic (PV) station as a one-off trip, in case of its failure in low voltage ride through (LVRT) is often inadequate for analyzing cascading failures in modern power systems with non-unique timescales.
