Resumen:
Nonlinear devices are increasing in all the power systems around the world and as a result the level of harmonic distortion in both voltage and current is growing. Computational deterministic analysis methods have been developed for power system harmonic prediction and assessment in order to give solutions to the harmonic distortion problem. Unfortunately, harmonic propagation in power systems usually does not have a deterministic nature because the behavior in both nonlinear and linear loads is usually known with uncertainties. This paper is a review of two different methodologies for considering uncertainties in the analysis: the probabilistic harmonic load flow (PHLF) and the fuzzy harmonic load flow (FHLF). Both methodologies are proven in a small test system and the results are compared showing some drawbacks. A new methodology, currently under development, which improves the FHLF, is also presented.
