Power Quality Composite Disturbance Identification Based on CWT–STFT Dual-Modal Fusion and a Lightweight Network
A lightweight Coordinate Attention ResNet network named ResNet–LCA is proposed based on the dual-modal time–frequency fusion of the Continuous Wavelet Transform and Short-Time Fourier Transform, which achieves coordinated optimization of classification accuracy, noise immunity and inference efficiency and can provide lightweight technical support for online intelligent power quality monitoring at the edge nodes of microgrids and islanded power systems.
