TL;DR: 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.
Journal ArticleDOI
On the Effects of Unbalances, Harmonics and Interharmonics on PLL Systems
TL;DR: The effects of unbalances, harmonics, and interharmonics on PLL systems are analyzed and a brief review of some typical schemes for three-phase and single-phase PLLs is performed.
Journal ArticleDOI
A Benchmark Test System to Evaluate Methods of Harmonic Contribution Determination
Igor Papic,Dejan Matvoz,Aljaz Spelko,Wilsun Xu,Yang Wang,Dave Mueller,Carl Miller,Paulo F. Ribeiro,Roberto Langella,Alfredo Testa +9 more
TL;DR: A benchmark test system representing a typical medium- voltage/low-voltage network supplying industrial loads is proposed and examples on how to use the system to assess the performance of harmonic contribution determination methods are included.
