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

Energy 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

Energy 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 ...

Lattice Boltzmann Method Simulations About Shale Gas Diffusion in Sinusoidal Channels

Energy Science &Engineering, EarlyView.
This paper characterizes the microscopic features of shale nanopores using sinusoidal functions and investigates the diffusion effects of methane gas in irregular nanopores through the lattice Boltzmann method. The result shows that methane is significantly influenced by large‐amplitude protrusions of the wall.
