Power Quality Improvement in Distributed Generation Resources using UPQC

Abstract

This paper examines the involved factors in creation of harmonics which have direct effects on the power quality issues specially, on three-wire systems. One of the main causes of harmonic distortion is the non-linear loads. Bearing in mind that Consistent with the consumer sector, the production sector can also be harmful in presence of unbalanced and Harmonic power supplies. In this study, a distributed generation (DG) case study to observe and evaluate of the impact of non-linear loads and also induction generators (IG) with power electronic interfaces – specially in wind turbine-based DGs are modeled, as the main sources of harmonics. In order to eliminate the harmonic generated in supply and demand sections of power system, UPQC is used, and the results of simulations demonstrate the reliefs of UPQC in rebate of non-linear loads and unbalanced power resources effectives.
