TLDR
In this paper, the second part of a two-part article reviewing the state-of-the-art of probabilistic aspects of harmonics in electric power systems is presented, including tools for calculating probabilities of rectangular and phasor components of individual as well as multiple harmonic sources.Abstract:
This paper represents the second part of a two-part article reviewing the state-of-the-art of probabilistic aspects of harmonics in electric power systems. It includes tools for calculating probabilities of rectangular and phasor components of individual as well as multiple harmonic sources. A procedure for determining the statistical distribution of voltages resulting from dispersed and random current sources is reviewed. Some applications of statistical representation of harmonics are also discussed.read more
