Design and Optimization of a Robust Wide‐Area Damping Controller for Mitigating Inter‐Area Oscillations in Wind‐Integrated Power Systems

open access: yesEnergy Science &Engineering, EarlyView.
ABSTRACT In power networks, low‐frequency oscillations—particularly inter‐area oscillations—pose a serious threat to system stability because of disruptions like short‐circuit faults and the increasing use of renewable energy sources like wind farms. To lessen the negative impacts of time delays when sending distant signals, this study presents a novel

Bolt Anchorage Quality Levels Classification Method Based on HO‐VMD‐CNN‐BiLSTM

open access: yesEnergy Science &Engineering, EarlyView.
First, the original ultrasound‐guided wave signal data is decomposed into multiple sub‐signals with varying frequencies using VMD to capture the multi‐scale features within the data. Second, the decomposed and noise‐reduced signal, processed by the HO‐VMD algorithm, is input into the CNN for further feature extraction through convolution and pooling ...

Juvenile salmonids traverse coastal meta‐nurseries that connect rivers via the sea

open access: yesFrontiers in Ecology and the Environment, EarlyView.
Conventionally, juvenile salmonids are thought to migrate unidirectionally from freshwater systems to marine systems and therefore only inhabit natal drainages. Although scattered evidence suggests juveniles can move bidirectionally between freshwater rivers and the ocean, including into non‐natal drainages, such movements have never been documented ...

Impact of Essential Oils Composition and Exposure Methods on Fungal Growth and Morphology: Insights for Postharvest Management

open access: yesFuture Postharvest and Food, EarlyView.
This study explores the effectiveness of essential oils in controlling postharvest phytopathogenic fungi for fruits and vegetables revealing how essential oils could offer sustainable solutions for reducing fungal contamination. By testing various oils in two methods, we identify Origanum vulgare, Syzygium aromaticum, and Cymbopogon citratus as potent ...
