TL;DR: In this article, the authors propose definitions for power terms in alternating current systems that are practical and effective when voltage and/or currents are distorted or unbalanced, and also suggest definitions for measurable values that may be used to indicate the level of distortion and unbalance.

TL;DR: In this paper, the authors present three harmonic simulation test systems for the preparation and analysis of harmonic problems through case studies and simulation examples, which can be used as benchmark for the development of new harmonic simulation methods and for the evaluation of existing harmonic analysis software.

TL;DR: In this paper, the most remarkable issues related to interharmonic theory and modeling are presented, starting from the basic definitions and concepts, attention is first devoted to inter-harmonic sources, and then the interharmonics assessment is considered with particular attention to the problem of the frequency resolution and of the computational burden associated with the analysis of periodic steady-state waveforms.

TL;DR: In this article, the authors present preliminary results from a national monitoring program designed to characterize power quality levels on electric distribution systems, which is being sponsored by the Electric Power Research Institute.

TL;DR: In this article, the authors provide practical guidance for assessing power system harmonic impedance, taking into account the considered network voltage (LV, MV or HV), the disturbing load importance (small or great contribution to the power network pollution) and the analytical and computational tools available.
