A Wavelet-Based Data Compression Technique for Smart Grid

  title={A Wavelet-Based Data Compression Technique for Smart Grid},
  author={Jiaxin Ning and Jianhui Wang and Wenzhong Gao and Cong Liu},
  journal={IEEE Transactions on Smart Grid},
This paper proposes a wavelet-based data compression approach for the smart grid (SG). In particular, wavelet transform (WT)-based multiresolution analysis (MRA), as well as its properties, are studied for its data compression and denoising capabilities for power system signals in SG. Selection of the Order 2 Daubechies wavelet and scale 5 as the best wavelet function and the optimal decomposition scale, respectively, for disturbance signals is demonstrated according to the criterion of the… CONTINUE READING
