Transition mechanism of an Inductive-resistive Superconducting Fault Current Limiter (IR-SFCL)
RE&PQJSuperconducting fault current limiters (SFCL) are protective devices that limit the current in power lines when it suddenly increases above a certain safe level as a consequence of a fault. This element is connected in series with the line and has a null impedance when the line current is below the safe value (limit current) but significative increase ...

A modified synchronverter for a weak grid with virtual power circles‐based PQ decoupling scheme
IET Renewable Power Generation, Volume 18, Issue 14, Page 2723-2736, 26 October 2024.A VSG is essential for ensuring stability of a power systems with high penetration of renewable energies, weak grid. Its control, however, is challenging due to the coupling of the active and reactive power which thus, requires virtual impedance. This article simplifies what type, kind and magnitude of the virtual impedance required to achieve a ...
