Fault coordination control for converter-interfaced sources compatible with differential protection during asymmetrical faults

open access: yesEnergy Reports, 2022
Converter-interfaced renewable energy sources (CIRESs) may have a different fault current angle with synchronous generators (SGs), so the large angle difference on both sides will cause low sensitivity or failure for traditional proportional braking ...

Hierarchical control-based fault ride-through of VSC-HVDC considering impacts of renewable energy

open access: yesInternational Journal of Electrical Power & Energy Systems
When a short-circuit fault occurs at the receiving-end grid, the unbalanced power in voltage source converter based high voltage direct current (VSC-HVDC) should be consumed to prevent excessive DC voltage rise, thereby enabling fault ride-through ...

Decentralised control and fault ride‐through of a multi‐microgrid system [PDF]

open access: yesIET Smart Grid, 2019
A multi‐microgrid (MMG) system comprises of a cluster of microgrids interconnected for reliable and efficient operation in grid connected as well as islanded modes. In this study, the fault‐ride‐through capability of an MMG system is addressed. A solution to under‐voltage and over‐current scenarios arising due to severe short‐circuit faults in inverter‐

Analysis of fault ride through in wind farms during network faults

open access: yesRenewable Energies, Environment and Power Quality Journal
Fault Ride Through (FRT) is a term used to describe the ability of wind farms to remain connected to the system during disturbances, such as short circuits or voltage drops. This capability is vital for maintaining the stability of power systems and preventing the adverse consequences that may arise from wind power outages during disturbances.

Fault Ride-Through Study of Wind Turbines

open access: yesJournal of Power and Energy Engineering, 2013
The installation of wind energy has increased rapidly around the world. The grid codes about the wind energy require wind turbine (WT) has the ability of fault (or low voltage) ride-through (FRT). To study the FRT operation of the wind farms, three methods were discussed.
