Power Quality Identification and Classification Using Wavelet Method in Smart Power Grids

In this paper, different methods of wavelet coefficients have been used to detect power quality in smart power grids and have investigated the advantages and disadvantages of continuous and discrete wavelet transforms in detection and performance of different mother wavelets in detecting different types. The perturbations are investigated by discrete wavelet transform. Also, in analyzing the power quality of smart grids, the type of disturbance in voltage or current signals is discussed.
