A New Modeling Approach For Power System Harmonic Analysis

Abstract

Accurate harmonic power flow studies rrquirr calculation of the steady state periodic solution for the network components rrprcsented in the studies. For components with switching sequence controls this task may be complex and computationally demanding. This paper presents a new and efficient method for computing the periodic steady state solution for components used in harmonic analysis. The method is based on state space representation of the components and optimal control theory. Results obtained from testing the method on a single-phase AC controller are prsented.
