摘要：

This paper is the companion of a paper of the same title, Part 1, where the theoretical aspects of two methods proposed in relevant literature for the assessment of waveform distortion in a wide range of frequency (i.e., from 0 to 150 kHz) are discussed. In particular, Part I dealt with the critical comparison of the sliding-window discrete Fourier transform (SWDFT), related to IEC standard harmonic estimation, and of the sliding-window wavelet-modified ESPRIT-based method (SWWMEM). In this paper, the two selected methods are compared in terms of accuracy and computational efforts on the basis of the numerical results obtained analyzing both synthetic and measured waveforms. The measured waveform comes from a photovoltaic system with broadband power line communication (BBPLC) power meters.
