Tunable-Q Wavelet Transform and Dual Multiclass SVM for Online Automatic Detection of Power Quality Disturbances

TL;DR: A new automated recognition approach based on tunable-Q wavelet transform and a dual multiclass support vector machines (MSVM) has been proposed for detection of power quality disturbances and results demonstrate the applicability, strength, and accuracy of the proposed approach for classification of single and combined disturbances under different noisy conditions.
Journal ArticleDOI

Estimation of Single-Phase and Three-Phase Power-Quality Indices Using Empirical Wavelet Transform

TL;DR: In this paper, an empirical wavelet transform (EWT)-based time-frequency technique is proposed for the estimation of power-quality indices (PQIs), which first estimates the frequency components present in the distorted signal, computes the boundaries, and then filtering is done based on the boundaries computed.
Journal ArticleDOI

A classification method for multiple power quality disturbances using EWT based adaptive filtering and multiclass SVM

TL;DR: An automated recognition approach for the classification of power quality (PQ) disturbances based on adaptive filtering and a multiclass support vector machine (SVM) is presented to elucidate the efficiency and robustness of the proposed approach against noise and different degrees of disorder.
Journal ArticleDOI

Visualizing time-varying power quality indices using generalized empirical wavelet transform

TL;DR: In this article, a generalized empirical wavelet transform (GEWT) is employed to assess all sorts of power signals having disturbances such as voltage fluctuation, sag, swell, interruption, transients, harmonics, and interharmonics.
Journal ArticleDOI

Realistic energy commitments in peer-to-peer transactive market with risk adjusted prosumer welfare maximization

TL;DR: A P2P market settlement mechanism which lowers this risk and maximizes the welfare of buyers and sellers, and gives room to the existing distribution system operators by assigning them the duty of optimally allocating energy.
