Electric utilities have expressed concern over increased nonlinear loading of residential power distribution systems. The number and variety of power electronic products found in the typical home continues to grow rapidly, imposing a burden on local power companies to supply reliable, distortion-free service. In order to adequately prepare for the future, utilities must be able to predict the harmonic...
This paper deals with modeling, analysis, and Monte Carlo simulation of three-phase voltage unbalance based on data measured from a 69/11-kV distribution substation. Random variation of the voltage unbalance factor is modeled with the aid of correlated Gaussian random variables that represent random variations in three-phase active and reactive powers. A network reduction technique using multiple-port...
