Abstract

Harmonic analysis is an important application to power systems and an efficient approach to evaluate the injected Total Harmonic Distortion (THD) of currents flowing into a power system due to the summation of randomly varying harmonic currents produced by AC/DC power converters is presented in this study. A probabilistic model is established to derive the magnitude of the injected harmonic currents using the expected value and variance of the harmonic current sources. This study presents a method for predicting the net harmonic current and voltage produced by a large number of electronic power converter loads at the Point of Common Coupling (PCC). Two of the more difficult aspects of applying IEEE Standard 519 are one determining an appropriate harmonic penetration Point of Common Coupling (PCC) and second establishing a harmonic model at the increasingly distributed loads test system. The estimated results obtain by simulating a distribution system show that the feasibility of the proposed method.
