A review of the effect of common fault current limiters (FCLs) on power systems reliability

The Journal of Engineering, Volume 2025, Issue 1, January/December 2025.
This article provides a literature review of the effect of FCLs on the reliability of various systems (such as substations and distribution systems) for the first time. It identifies research gaps and challenges in this field. According to identified gaps, it provides suggestions for future works to the researchers.

Simulation study of integrated‐gate‐commutated‐thyristor based superconducting hybrid direct current circuit breaker

High Voltage, 2023
With the development of a distributed generation, direct current (DC) load and energy‐storage equipment, voltage‐source‐converter‐based medium‐voltage DC systems (VSC‐MVDC) have attracted more attention due to its low power consumption, high reliability,

Optimal Protection Planning and Coordination in Microgrids With SDGs, SFCLs, and OCR Using WOA

International Journal of Energy Research, Volume 2025, Issue 1, 2025.
One of the critical challenges in power system protection is ensuring proper relay coordination. To achieve optimal coordination of protection systems and ensure security, fast cleaning, and selection of types of faults is a necessary priority. This priority, when hosting synchronous distributed generations (SDGs), although technical factors like power

Complementing ODE-Based System Analysis Using Boolean Networks Derived from an Euler-Like Transformation [PDF]

, 2011
In this paper, we present a systematic transition scheme for a large class of ordinary differential equations (ODEs) into Boolean networks. Our transition scheme can be applied to any system of ODEs whose right hand sides can be written as sums and ...

Three-Phase Saturated-Core Fault Current Limiter

Energies, 2018
The saturated-core fault current limiter (SFCL) is widely used to limit the fault current. However, in the conventional SFCL structure, alternating current (AC) and direct current (DC) coils are wound on different loosely coupled cores.

Current limiting characteristic of saturated iron core SFCLs

Journal of Physics: Conference Series, 2010
Saturated Iron Core SFCL (SIC-SFCL) provides an attractive option for the suppression of fault current level in a high voltage or an extra-high capacity electric power network. Different from traditional devices, such as air core reactors, high resistance transformers, etc., the impedance of SIC-SFCL can change from very low in normal power ...

An Overview of VSC‐HVDC Systems and Challenges to Harvest Wind Energy Potential Considering South Asian Region as a Case Study

International Journal of Energy Research, Volume 2025, Issue 1, 2025.
The voltage source converter‐based high voltage direct current transmission (VSC‐HVDC) is considered the most appropriate option to harness the maximum potential of renewable energy, particularly offshore wind. With improved reliability and functionality of the network, reduced conversion losses, and reduced cost, the VSC‐based multiterminal direct ...

A Modified Loss of Synchronism Condition for Efficient Critical Clearing Time (CCT) Estimation in Transient Stability Analysis

International Transactions on Electrical Energy Systems, Volume 2025, Issue 1, 2025.
Accurate determination of critical clearing time (CCT) remains a fundamental challenge in transient stability analysis of power systems, primarily due to the highly nonlinear and complex dynamic behavior of multimachine networks. Existing methods based on the loss of synchronism (LOS) condition often require intensive numerical iterations and may ...
