A Comprehensive Method to Mitigate Forced Oscillations in Large Interconnected Power Grids
IEEE Access, 2021 Multiple severe forced oscillation events have recently been observed across the North American interconnections and around the world. These forced oscillations have caused power swings, limited power transfer capability, damaged equipment, and persisted

A New Acoustic Emission Source Location Method Using Tri-Variate Kernel Density Estimator
IEEE Access, 2019 A new AE location method using tri-variate kernel density estimator is developed in this paper. Firstly, combinations of every six arrivals are obtained from a multi-sensor location system, and the preliminary location results are obtained by solving the

Noise Source Location Optimization
Shock and Vibration, 1994 This article describes a method to determine locations of noise sources that minimize modal coupling in complex acoustic volumes. Using the acoustic source scattering capabilities of the boundary element method, predictions are made of mode shape and ...

Robust Localization for Near- and Far-Field Signals with an Unknown Number of Sources
Fractal and Fractional, 2023 Source location is a constant issue of importance of both theoretical study and practical engineering. Many pioneers have put out the corresponding solutions for near- or far-field signals, and preferred contributions are suggested. To our best knowledge,
