Modeling and Mitigation of Harmonic Distortions Caused by Mass-Distributed Harmonic Sources
DownloadFall 2017
In recent years, the proliferation of energy-efficient but harmonic-producing home appliances has significantly changed the nature of power system harmonic problems. One of the main concerns nowadays is the harmonics produced by small, mass-distributed harmonic sources. Their unique random and...

This Thesis proposes a novel transform called “Channel Components Transform” and presents its application to power system voltage stability assessment. The transform is based on the following observation: a power network can be represented as a multi-node, multi-branch Thevenin circuit connecting...
