Voltage collapse prediction and control of a power system using hybridized classical probability theory and voltage stability indices

Discover Electronics
The incessant voltage collapse incidences on the Nigeria National grid is a serious concern. The primary dependability issue of voltage collapse makes it difficult to operate a reliable and secure power system network.

A STEADY-STATE APPROACH TO PREVENT VOLTAGE COLLAPSE IN POWER SYSTEM

Ingeniería, 2013
This paper presents a steady state approach to prevent voltage collapse in a power system. The power system operation close to stability boundaries is an important factor which may lead to voltage instability conditions.

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

FEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Voltage Collapse Stabilization in Star DC Networks [PDF]

2019 American Control Conference (ACC), 2019
Voltage collapse is a type of blackout-inducing dynamic instability that occurs when the power demand exceeds the maximum power that can be transferred through the network. The traditional (preventive) approach to avoid voltage collapse is based on ensuring that the network never reaches its maximum capacity.

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.

Performance Comparison of LCC and VSC HVDC Systems in Minimizing Long-Term Voltage Collapse

IEEE Access
High-voltage direct current (HVDC) transmission helps transmit large energy blocks over long distances. Line-Commutated Converters (LCC) and Voltage Source Converters (VSC) can be used for this purpose.

Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential

FEBS Letters, EarlyView.
Aging reshapes the gut microbiome (↓SCFA‐producing commensals; ↑pro‐inflammatory outputs), shifting circulating metabolites (↓SCFAs; ↑LPS, ↑TMAO, ↑PAA) that act at the BBB to increase nonspecific transcytosis, alter transport, and promote astrocyte reactivity, heightening brain vulnerability.

Stability analysis and voltage improvement in DG-integrated distribution networks using VCPI-based critical buses and lines detection considering uncertain power factor

Ain Shams Engineering Journal
Voltage stability ensures reliable and efficient power transmission to end-users, making it essential for power system efficiency. Dynamic load changes and rising power requirements might cause voltage instability and strain performance.
