English Abstract

In this article, self-adaptive variational mode decomposition (SAVMD), deep convolutional neural networks (DCNN), and online-sequential random vector functional link networks (OSRVFLN) are integrated to categorize the single as well as combined power quality events (PQEs) in real time. The SAVMD method is proposed to optimize both the number of decomposition and data-fidelity factor to extract the...
