Transient synchronization stability analysis of PV grid-tied systems considering whole LVRT process

International Journal of Electrical Power & Energy Systems
Large-scale photovoltaic power generation makes the transient characteristics of power grid under severe faults particularly complicated. Different from the traditional synchronous generator, the transient stability condition and evolution law of the PV ...

Epigenetic blind spots – the role of DNA methylation dynamics in stem cell‐based models of embryogenesis

FEBS Letters, EarlyView.
Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

FEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Impacts of Integration of Wind Farms on Power System Transient Stability

Applied Sciences, 2018
To compensate for the ever-growing energy gap, renewable resources have undergone fast expansions worldwide in recent years, but they also result in some challenges for power system operation such as the static security and transient stability issues. In

Current limiting algorithms and transient stability analysis of grid-forming VSCs

, 2020
This paper consists first in comparing the well-known virtual impedance and current saturation algorithms in case of a three-phase short circuit. During the fault, the virtual impedance has an indirect action on the AC current since it depends mainly on ...

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

FEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

Phosphoinositides and inositol phosphates as molecular glues

FEBS Letters, EarlyView.
Inositol phosphates (IPs) and phosphoinositides (PIPs) regulate diverse eukaryotic processes. Beyond recruiting signaling proteins or acting as structural cofactors, recent studies suggest they mediate protein–protein interactions as natural molecular glues.

Transient stability analysis of wind-thermal bundled system based on virtual inertia control

The Journal of Engineering, 2019
In this study, the transient stability characteristics of the wind-thermal bundled system is discussed when the wind turbine adopts the additional control of virtual inertia.

Three phosphatase families form a community: The phosphohydrolases that act upon inositol pyrophosphates

FEBS Letters, EarlyView.
Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.
