Susceptibility of Large Wind Power Plants to Voltage Disturbances — Recommendations to Stakeholders
Journal of Modern Power Systems and Clean Energy, 2022 Sufficient fault ride-through (FRT) of large wind power plants (WPPs) is essential for the operation security of transmission system. The majority of studies on FRT do not include all disturbances originating in the transmission system or the ...

Enhancing Data Center Low-Voltage Ride-Through
CoRRData center loads have expanded significantly in recent years. Compared to traditional loads, data centers are highly sensitive to voltage deviations and thus their protection mechanisms trip more proactively during voltage fluctuations. During a grid fault, simultaneous tripping of large-scale data centers can further destabilize the transmission ...

LVRT Control Strategy for Asymmetric Faults of DFIG Based on Improved MPCC Method
IEEE Access, 2021 In the case of asymmetric fault, the modern new power grid requires that the doubly-fed induction generator (DFIG) still has good low voltage ride-through (LVRT) capabilities. To solve this problem, a low voltage ride-through control strategy based on an

Predictive Ability of Plasma p‐tau217 for β‐Amyloid Status: A Prospective Multicenter Study
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Plasma tau phosphorylated at threonine 217 (p‐tau217) measured with fully automated platforms has shown high accuracy for Alzheimer's disease (AD) diagnosis, but real‐world multicenter data remain limited. We aimed to validate the diagnostic performance of p‐tau217 for identifying AD pathology in a real‐world multicenter cohort ...
