Sensitivity analysis of critical clearing time in power systems with high penetration of power electronic devices
Tsinghua University PressPeer-Reviewed Publication
The CCT sensitivity calculation method proposed in this study provides a new tool for stability analysis in power systems with a high proportion of power electronic devices. By considering the effects of current limiting and control switching, as well as scenarios where stability boundaries are controlled by periodic orbits (POs), the method quantifies the impact of various parameters on system stability and offers guidance for adjusting inverter control parameters. Future research could further refine the CCT calculation method and integrate CCT sensitivity into optimization models to enhance system stability through improved inverter control strategies.

Probiotic may improve sleep quality: new research findings
Higher Education PressPeer-Reviewed Publication
A new study in Engineering reveals that S-adenosylmethionine (SAM) - producing probiotics might be a potential way to manage sleep disorders. The research identified Lactobacillus helveticus CCFM1320 as a promising probiotic. Tests on sleep-deprived mice and a clinical trial with insomnia patients showed that it could improve sleep quality, and the findings suggest a non-pharmacological alternative for treating sleep problems.

Research infrastructure for innovative power grids
Karlsruher Institut für Technologie (KIT)Business Announcement
Electricity is increasingly being supplied by distributed sources of renewable energy, replacing central power plants and changing the demands on power grids. At the High Power Grid Lab (HPGL), new grid technologies are to be analyzed in a test environment designed to emulate the real power grid as accurately as possible. The focus will be on low- and medium-voltage grids for regional power distribution. The test platform is set to begin operation in 2030 as part of the Energy Lab at the Karlsruhe Institute of Technology (KIT). Its construction is being funded with EUR 32.8 million in strategic development funding from the Helmholtz Association.

We are vastly overestimating the amount of fresh water available for lithium mining, new study finds
University of Massachusetts AmherstPeer-Reviewed Publication
New research into lithium mining in the “Lithium Triangle” of Chile, Argentina and Bolivia — source of more than half of the world’s lithium resources — shows that the commonly accepted models used to estimate water how much water is available for lithium extraction and what the environmental effects may be are off by more than an order of magnitude. The paper, published in Communications Earth and Environment, reveals that there is far less water available than previously thought. With demand for the mineral, which is critical for batteries powering the green transition, projected to increase 40-fold in the coming decades, the research suggests local communities, regulators and the lithium mining industry must quickly collaborate to bring their water usage within sustainable limits.
