Grid-Forming Inverter with Simplified Virtual Synchronous Compensator Providing Grid Services and Grid Support [PDF]

open access: yes, 2021
This paper proposes a Simplified Virtual Synchronous Compensator (S-VSC) model with grid-forming capabilities for microgrid applications. Previous works have shown how the S-VSC can provide grid services (i.e., virtual inertia, current harmonic ...

Direct AC voltage control for grid-forming inverters [PDF]

open access: yesJournal of Power Electronics, 2019
Grid-forming inverters usually use inner cascaded controllers to regulate output AC voltage and converter output current. However, at the power transmission system level where the power inverter bandwidth is limited, i.e., low switching frequency, it is difficult to tune controller parameters to achieve the desired performances because of control loop ...

ALDOA Promotes Glycolysis and NLRP3/GSDMD Pyroptosis to Accelerate ALS Progression

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Amyotrophic lateral sclerosis (ALS) is characterized by progressive motor neuron degeneration. Glycolytic dysregulation is implicated in disease progression, yet the underlying mechanisms remain unclear. This study investigates how Aldolase A (ALDOA) drives ALS progression through glycolysis‐mediated motor neuron pyroptosis.

Improved Damping Control of Grid-forming Inverter Using DC Dynamics [PDF]

open access: yes, 2023
The DC side of the grid-forming inverter is usually simplified as an ideal source when considering the AC dynamics. However, the DC dynamics actually contain useful information of the AC side.

Composites of Shellac and Silver Nanowires as Flexible, Biobased, and Corrosion‐Resistant Transparent Conductive Electrodes

open access: yesAdvanced Functional Materials, EarlyView.
Shellac, a centuries‐old natural resin, is reimagined as a green material for flexible electronics. When combined with silver nanowires, shellac films deliver transparency, conductivity, and stability against humidity. These results position shellac as a sustainable alternative to synthetic polymers for transparent conductors in next‐generation ...
