Estimating Future Grid Harmonics Due to Changing Harmonic Sources   William Howe, Matthew Rylander   2017/04/25

Abstract

Unprecedented changes in both end-use loads and grid management have raised concerns about increasing harmonics levels on T&D grids. Of particular concern is now to estimate future harmonics levels for existing circuits in a reliable and repeatable way as the composition and nature of loads change.
A harmonic evaluation module that has been developed by EPRI (Electric Power Research Institute) is an effective tool for estimating the harmonic impacts on distribution systems of increased penetration of newer harmonic sources. This paper focuses on aspects of that tool and how tools and techniques of this sort can be employed to improve grid management and planning.
