Challenges of renewable energy integration to weak grids

open access: yes, 2023
This paper presents the stability challenges of integrating large-scale renewable generations into the weak grid based on a review of literature and other public information. Moving from synchronous generator-based grids to converter-dominant power grids,

Molecular characterization of covRS mutations in M1UK Streptococcus pyogenes

open access: yesFEBS 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.

Voltage Weak DC Distribution Grids [PDF]

open access: yesElectric Power Components and Systems, 2017
AbstractThis paper describes the behavior of voltage weak DC distribution systems. These systems have relatively small system capacitance. The size of system capacitance, which stores energy, has a considerable effect on the value of fault currents, control complexity, and system reliability.

GelMA‐based 3D spheroids recapitulate transcriptomic and functional hallmarks of myeloid sarcoma

open access: yesFEBS Open Bio, EarlyView.
GelMA 5% hydrogels support the formation of myeloid leukemia spheroids that recapitulate MS‐specific features, including G1 arrest, apoptosis, and ECM‐driven transcriptomic reprogramming. The 3D model mimicked soft‐tissue‐like stiffness and oxygen conditions, and transcriptomic convergence with primary MS samples confirmed its utility as a preclinical ...

Coordinated Control of Active and Reactive Power Compensation for Voltage Regulation with Enhanced Disturbance Rejection Using Repetitive Vector-Control

open access: yesEnergies, 2020
Voltage profile is one of many aspects that affect power quality in low-voltage distribution feeders. Weak grids have a typically high line impedance which results in remarkable voltage drops.

Robust PLL Synchronization Unit for Grid-Feeding Converters in Micro/Weak Grids

open access: yesIEEE Transactions on Industrial Informatics, 2023
A grid-feeding voltage source converter (GFD-VSC) requires a phase-locked loop (PLL) synchronization unit to be connected to the grid. The PLL critically affects the dynamic performance and stability of the GFD-VSC. In particular, a PLL with in-loop filtering, for working under distorted/polluted conditions, possesses a narrow stability margin and ...

Plasma EV Proteomics Identifies ECM Remodeling and Inflammatory Proteins LUM and C7 as Candidate Biomarkers in FSHD

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Facioscapulohumeral muscular dystrophy (FSHD) is one of the most debilitating and common muscular dystrophies. Despite its severity, no approved therapy exists for FSHD patients. However, several therapeutic candidates are currently under development, and some have recently entered clinical trials, marking the need for reliable ...

Single-Sensor Inverter-Side Current Feedback With Band-Pass-Filter Active Damping for Robust Control of LCL Grid-Connected Inverters Under Weak-Grid Conditions

open access: yesIEEE Open Journal of Power Electronics
LCL-filtered grid-connected voltage-source inverters provide excellent switching-harmonic attenuation, but their resonant dynamics combined with digital delays can destabilize conventional current control.
