A compound control strategy of three‐phase Vienna rectifier under unbalanced grid voltage
IET Power Electronics, 2021 When traditional finite‐set predictive power control is applied to Vienna rectifier, the input current will produce a large number of third harmonics under unbalanced power network, which will seriously affect the normal operation of Vienna rectifier ...

Analysis of Unbalanced and Inadequate Development of Power Grids
IOP Conference Series: Materials Science and Engineering, 2019 Abstract The principal contradiction facing Chinese society has evolved. What we now face is the contradiction between unbalanced and inadequate development and the people’s ever-growing needs for a better life. As power grids play a significant role in energy resource distribution and utilization, the quality of power grid development ...

Unbalanced Voltage Compensation Using Grid-Connected Photovoltaic System
AUT Journal of Electrical Engineering, 2022 Appropriate power quality is indispensable for electrical distribution networks, especially in microgrids including renewable energy sources. One of the critical issues affecting power quality is the unbalanced voltage. Voltage imbalance in microgrids spreads due to proximity of loads and power sources, causing instability, and eventually interruption.

Optimal Power Flow for Unbalanced Bipolar DC Distribution Grids
IEEE Access, 2018 The emergence of distributed energy resources can lead to congestion in distribution grids. DC distribution grids are becoming more relevant as more sources and loads connected to the low voltage grid use dc. Bipolar dc distribution grids with asymmetric loading can experience partial congestion resulting in a nodal price difference between the two ...

Fully Digital Grid Synchronization Under Harmonics and Unbalanced Conditions [PDF]
IEEE Access, 2019 For the grid-connected system, the unbalanced and harmonic components of three-phase grid voltage have a significant impact on the accuracy of grid synchronization. And the positive, negative sequences, harmonics, as well as dc component of the three-phase grid voltage are difficult to separate and extract in a fast and precise way.

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