Identification of dominant instability modes in power systems based on spatial‐temporal feature mining and TSOA optimization

open access: yesIET Generation, Transmission & Distribution
The recognition of the transient dominant instability mode is of great significance for rapidly and accurately formulating transient emergency decisions in power systems. In response to the challenge of accurately distinguishing between angle instability

Application of fuzzy logic to power system stabilizer [PDF]

open access: yes, 2008
Power systems stability is a complex problem which was first recognised in 1920 and has been widely investigated by power system engineers ever since.

The newfound relationship between extrachromosomal DNAs and excised signal circles

open access: yesFEBS Letters, EarlyView.
Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

Recognition of transient instability scenarios of the receiving-end grid and control strategy optimization

open access: yesZhejiang dianli, 2023
Under the influences of AC-DC coupling, uncoordinated network-source development, and new energies that fail to meet the demand of grid-related performance, power system stability is becoming a point of extreme gravity. The correlation characteristics of

Synchronization and Transient Stability in Power Networks and Non-Uniform Kuramoto Oscillators [PDF]

open access: yes, 2011
Motivated by recent interest for multi-agent systems and smart power grid architectures, we discuss the synchronization problem for the network-reduced model of a power system with non-trivial transfer conductances.

Structural biology of ferritin nanocages

open access: yesFEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...
