Optimizing Fault Ride-Through of DGs in Distribution Networks to Preserve Recloser-Fuse Coordination

IEEE Access
Fuse saving protection is usually applied in distribution networks, through auto-reclosing, to prevent fuse burning under transient faults. The modern fault ride-through (FRT) standards, which require distributed generators (DGs) to remain connected ...

Fault Ride-through Capability Enhancement of Voltage Source Converter-High Voltage Direct Current Systems with Bridge Type Fault Current Limiters

Energies, 2017
This paper proposes the use of bridge type fault current limiters (BFCLs) as a potential solution to reduce the impact of fault disturbance on voltage source converter-based high voltage DC (VSC-HVDC) systems.

Design and Optimization of Dynamic Voltage Restorers for Enhancing Power Quality and Fault Ride through (FRT) in Grid-Integrated Hybrid Energy Systems

SMART MOVES JOURNAL IJOSCIENCE
The integration of renewable energy sources, such as solar and wind, into modern power grids presents challenges in maintaining power quality and stability, particularly under fault conditions like voltage sags and swells. This research focuses on the design and optimization of Dynamic Voltage Restorers (DVRs) to enhance power quality and Fault Ride ...

Development of a generic future grid code regarding wind power in Europe [PDF]

, 2017
Present grid codes might not be a suitable reference for future-oriented research. The diversity of grid codes by different transmission system operators makes it challenging to get a clear and compact general overview on grid code requirements.

A Novel Hybrid Statistical Method for Power Swing Detection in Transmission Lines With Grid‐Following Inverter

IET Generation, Transmission &Distribution, Volume 19, Issue 1, January/December 2025.
This paper develops a novel statistical framework, integrating a cumulative sum control chart and entropy analysis, for power swing and fault discrimination, which enables accurate detection and differentiation of faults and power swings in grid‐following‐connected transmission lines.

Enabling Temporary Blocking of Offshore Converters Through Grid‐Forming Wind Turbines to Assist HVDC Grid Protection

IET Generation, Transmission &Distribution, Volume 19, Issue 1, January/December 2025.
The paper higlights the usage of GFM WTG to enable temporary blocking of the offshore converter in MT‐HVDC systems to reduce protection requirements. It is shown, that smaller DCCB series inductances can be used. During temporary blocking the AC power transfer is interupted but is returned quickly after the converter is brought back into operation ...

Improving fault ride‐through capability for doubly‐fed induction generator based on improved system structure and corresponding control scheme

IET Energy Systems Integration
Although there are many methods to improve the fault ride‐through (FRT) capability of doubly‐fed induction generator (DFIG) systems at present, each method has its shortcomings, especially the applicability under different voltage dips (VDs), so an ...
