Grid-connected converter control during unbalanced grid conditions based on delay signal cancellation

open access: yesInternational Transactions on Electrical Energy Systems, 2018
Considering the recent trend in the development, it has become very hard to imagine modern power system without the integration of power electronic devices. A grid connected converter will be on the forefront of future energy trading, while simultaneously striving to offer good dynamic behaviour and operation in full accordance with the relevant grid ...

Distorted Unbalanced Grid Voltage Modulated Direct Power Control for Three-Phase Grid-Connected Inverters

open access: yesIEEE Open Journal of Power Electronics
In this paper, a linearized direct power control strategy for grid-connected inverters under distorted unbalanced grid voltage is proposed. The grid-connected inverters usually suffer from distorted unbalanced grid condition, which causes output active ...

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.
