Grid‐forming requirements based on stability assessment for 100% converter‐based Irish power system

open access: yesIET Renewable Power Generation, 2022
The fault response of a 100% converter‐based system can be significantly different to that of a synchronous generator‐based system, considering the lower capacity headroom, but flexible control capability, of power electronic converters.

Impact of Digital Control Delay on Stability of Grid-Following Converters

open access: yes2022 IEEE 13th International Symposium on Power Electronics for Distributed Generation Systems (PEDG), 2022
In a digital controlled system, the delay is inevitable. It will change the phase-frequency characteristics of the system, which will affect the stability. This paper analyzes the configuration of the grid-following converter and builds its small-signal model in detail.

A light‐triggered Time‐Resolved X‐ray Solution Scattering (TR‐XSS) workflow with application to protein conformational dynamics

open access: yesFEBS Open Bio, EarlyView.
Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...
