Fuzzy harmonic power flow analyses

Abstract

Harmonic penetration is an important task in the harmonic analysis for both electric power utilities and industries. This paper investigates the fuzzy harmonic power flow method (FHPF) taking the fuzzy harmonic model into account. The solution is obtained via solving a set of 4n/spl times/4n linear equations where n is the bus number. The fuzzy solutions for both harmonic magnitudes and phase angles can be expressed by two explicit linear equations individually. The characteristics of the fuzzy harmonic power flow solutions were explored using an 18-bus system.
