A generalized load modeling technique using actual recorded data and its use in a harmonic load flow program

Abstract

This paper consists of two parts. While the first part presents a new time domain load modeling technique that is based on actual recorded steady-state power system measurements, the second demonstrates the incorporation of the developed load model into a harmonic load flow program that is based on the bus admittance matrix method. The developed load model, a perfectly general one, can be used to model linear or nonlinear loads in the presence or absence of harmonic distortion. Conceptually it is shown that the calculation of the power components by using the developed model becomes an easy task, even in the presence of harmonic distortion. The problem of power factor correction in the presence of harmonic distortion is finally addressed and it is shown that the developed method yields better results than the conventional method of power factor correction.
