Multi-Timescale-Based Fault Section Location in Distribution Networks
IEEE Access, 2021 To meet the requirements of quickness and accuracy for fault location in smart distribution networks with high penetration of distributed generations, we propose an integrated fault section location method based on multiple timescales. On the millisecond

Spatio-temporal evolution of intraplate strike-slip faulting: the Neogene-Quaternary Kuh-e-Faghan Fault, Central Iran [PDF]
, 2016 Central Iran provides an ideal region to study the long-term morphotectonic response to the nucleation and propagation of intraplate faulting. In this study, a multidisciplinary approach that integrates structural and stratigraphic field investigations ...

FEBS Letters, EarlyView.This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

A Practical Protection Coordination Strategy Applied to Secondary and Facility Microgrids
Energies, 2012 In a conventional distribution system, protection algorithms are designed to operate on a unidirectional high fault-current level. In a microgrid, a fault current from distributed generation (DG) may bring about a relay malfunction because of the ...

Modular multilevel converter with modified half-bridge submodule and arm filter for dc transmission systems with DC fault blocking capability [PDF]
, 2018 Although a modular multilevel converter (MMC) is universally accepted as a suitable converter topology for the high voltage dc transmission systems, its dc fault ride performance requires substantial improvement in order to be used in critical ...

FEBS Letters, EarlyView.Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

A Fault Tolerance Method for Multiple Current Sensor Offset Faults in Grid-Connected Inverters
Machines, 2023 Three-phase grid-connected inverters have been widely used in the distributed generation system, and the current sensor has been applied in closed-loop control in inverters. When the current sensor offset faults occurs, partial fault features of multiple
