Embedding PMU Algorithms in Grid-Following Converters: a Feasibility Study

2025 IEEE International Instrumentation and Measurement Technology Conference (I2MTC)
One of the most critical challenges in the evolution of smart grids is the shortage of measurement devices at the distribution level, coupled with the high costs associated with extensive refurbishment of the existing monitoring infrastructure. To address this issue, this paper investigates the feasibility of upgrading the controllers of smart Power ...

Grid-Synchronization Stability of Converter-Based Resources—An Overview

IEEE Open Journal of Industry Applications, 2020
This paper presents an overview of the synchronization stability of converter-based resources under a wide range of grid conditions. The general grid-synchronization principles for grid-following and grid-forming modes are reviewed first. Then, the small-

A Comparative Study of Grid-Following and Grid-Forming Control Schemes in Power Electronic-Based Power Systems

Power Electronics and Drives, 2023
Along with de-carbonisation, the penetration of power electronic converters has increased, and the power system has become a power electronic-based power system. In such a situation, the stability of the power system faces great challenges.

An Alternative Control Structure for Grid-Following Converters of Inverter-Based Resources

IEEE Open Access Journal of Power and Energy, 2023
In this paper, an alternative control structure of grid-following control is proposed and applied in inverter-based resources (IBRs). An IBR’s grid-following control normally employs Power/Voltage (P/V) control strategy to control the output real power and the voltage at the point of common coupling bus.

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

FEBS 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 ...

Molecular characterization of covRS mutations in M1UK Streptococcus pyogenes

FEBS Open Bio, EarlyView.
Group A Streptococcus (GAS) acquires covRS mutations driving a hypervirulent bacterial state, frequently associated with invasive disease‐like necrotizing fasciitis. We demonstrate that the newly emerged M1UK GAS lineage can also acquire these mutations.
