A Novel Method for Screening the PMU Phase Angle Difference Data Based on Hyperplane Clustering

IEEE Access, 2019
Compared with the traditional supervisory control and data acquisition (SCADA) data, phasor measurement unit (PMU) data is characterized by phase angle measurement and high reporting speed (perhaps 100 Hz).

Mechanisms of Degradation in Li‐Ion Batteries Under Low Temperature Exposures

Advanced Functional Materials, EarlyView.
Low‐temperature exposures, or freeze‐thaw cycles, are observed to significantly accelerate the degradation of Li‐ion batteries. A combination of electrolyte phase separation and mechanochemical stress leads to reversible and irreversible performance losses.

Charge‐Tunable Coacervate Micelles for Separator Engineering in Lithium‐Sulfur Batteries

Advanced Functional Materials, EarlyView.
A separator engineering strategy based on charge‐tunable complex coacervate core micelles (C3Ms) is presented to form an ion‐selective layer regulating polysulfide transport in Li–S batteries. The micelles enable uniform adsorption onto commercial polypropylene separators and infiltration throughout the internal pore network, suppressing polysulfide ...

Interaction energy-based power coupling oscillation analysis and suppression of grid-forming converter connected system

International Journal of Electrical Power & Energy Systems
The power coupling effect of the grid-forming converter will cause instability oscillation when it connects to low-voltage short-distance transmission lines. To solve this problem, this paper presents an energy interaction analysis method for oscillation
