Inverse time overcurrent protection for low-frequency wind farm transmission lines based on transient current components

International Journal of Electrical Power & Energy Systems
Low-Frequency Transmission Systems (LFTS) integrate the benefits of both high-voltage alternating current (HVAC) and high-voltage direct current (HVDC) transmission technologies. This combination makes LFTS a significant innovation for transmitting large

Service restoration strategy for active distribution networks considering source-load uncertainty

International Journal of Electrical Power & Energy Systems
Active distribution networks (ADNs) incorporate numerous distributed generations (DGs) and energy storage systems. When sudden faults occur in the system, service restoration can be enhanced through microgrid formation and network reconfiguration ...

Arterial Spin‐Labeling MRI at the Cortical‐CSF Interface: A Novel Biomarker in Alzheimer Disease

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background/Objective Arterial spin‐labeling (ASL) MRI can measure perfusion signal adjacent to CSF spaces and may provide information regarding CSF‐adjacent water transport physiology. We developed an automated pipeline to extract cortical‐CSF interface (IF) perfusion for comparison between Alzheimer disease (AD) and cognitively normal ...

Multi-terminal flexible DC grid circuit breaker withstands multi-lightning strike analysis

Scientific Reports
Lightning represents the primary threat to power grids, with approximately 80% of natural occurrences being multi-lightning strikes, which have been extensively studied and confirmed to pose even more severe hazards.

dynoGP: Deep Gaussian Processes for Dynamic System Identification

International Journal of Adaptive Control and Signal Processing, EarlyView.
This work introduces a novel class of deep models for system identification, dynamical deep Gaussian processes, which combine the strengths of data‐driven methods, such as those based on neural network architectures, with the ability to output a probability distribution for uncertainty representation.

Short-Circuit Analysis of DER-Based Microgrids in Connected and Islanded Modes of Operation

Energies, 2021
Since microgrids should be able to smoothly operate in two distinct modes—grid-connected and islanded, their fault currents can widely fluctuate depending on the operational mode. When the microgrid is connected to the grid, the highest fault current, by
