Harmonic Model and Propagation in Power System: A Review

Recent rapid interest in renewable energy generation, especially high penetration of grid-connected renewable energy system, is imposing new challenges to the harmonic model and propagation in power system. In practice, there is a potential risk of harmonic interaction resonance and harmonic propagation. It is of great importance to identify which kind of harmonic model and harmonic propagation are for further harmonic analysis. This review will help reader to understand the following important questions: How to model the harmonics generation from power converters? How to model the transportation of harmonics in power system? How the harmonic affect the power quality. It will provide a useful reference to researchers and engineers who concern about harmonic problems resulted from the grid-connected renewable energy systems.
