Identification of electromechanical oscillatory modes based on variational mode decomposition

Electric Power Systems Research, 2019
Abstract This paper introduces Variational Mode Decomposition (VMD) to identify electromechanical oscillatory modes in power systems. The identification process is based on the time-frequency analysis of nonlinear signals which arise after a large disturbance.

Detection of voltage variation events using variational mode decomposition

2017 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC), 2017
This paper presents a method of detecting voltage sag, swell and interruption events based on a signal processing tool viz. variational mode decomposition (VMD). The proposed method is able to keep track of variations in amplitude, phase, frequency and undelivered energy due to such events.

Image dehazing using variational mode decomposition

2017 International Conference on Wireless Communications, Signal Processing and Networking (WiSPNET), 2017
Haze is caused by the scattering of airtight in atmosphere and it deteriorates the contrast of the photographs. Here, we propose a novel approach for haze removal based on Two Dimensional Variational Mode Decomposition (2D VMD). Two dimensional VMD decomposes the input image into desired number of bands with different central frequencies. From this set
