Harmonic simulation techniques (methods & algorithms)

This paper describes the gained experience on the development and application of techniques for the modeling and analysis of power systems with nonlinear and time-varying components for accurate harmonic analysis. These methodologies have been developed in the time, frequency and hybrid time and frequency domain frames of reference. Their application to the computation of the periodic steady state solution of different test systems is detailed, indicating their advantages and limitations in terms of efficiency, computer requirements and accuracy.
