A Probabilistic Bottom-up Technique for Modeling and Simulation of Residential Distributed Harmonic Sources

The proliferation of energy-efficient appliances and modern consumer electronics has resulted in numerous power-electronic-based harmonic sources penetrating into residential households. Due to the huge number and wide adoption of these new harmonic sources, techniques for determining the cumulative harmonic impact of them are urgently needed.;A probabilistic bottom-up technique is proposed in this thesis to model aggregated harmonic sources and other linear loads. This technique not only takes into account appliances' daily usage pattern as well as household activities, but also provides the flexibility to represent future market trends and policy changes. By modeling the residential distribution systems with this technique, one can estimate how serious the harmonic impacts become when more harmonic-producing appliances penetrate into the residential loads.;The proposed technique has also been applied to evaluate the power quality impact of charging plug-in hybrid electric vehicles (PHEVs) on residential distribution systems.
