Abstract

A harmonic power flow method that analyzes harmonics in unbalanced power systems is presented. The developed algorithm has two steps which are executed successively: the first is a fundamental frequency power flow for the AC linear network in which nonlinear loads are represented by current sources; the second is a frequency domain iterative Newton-Raphson method to calculate the harmonics generated by nonlinear loads. In this second step, the AC linear network is represented by a generalized Thevenin equivalent with respect to the nonlinear loads, obtained from the power flow solution. Both linear and nonlinear loads are considered in terms of power
