Paper Title
Comparison of Reference Current Generation Schemes for Distributed Generation Units under Unbalance Faults

Abstract
This paper investigates different current generation schemes for controlling positive and negative sequence currents of distribution generation units under unbalanced grid voltage conditions. A comparison of the reference current generation schemes, for a grid connected converter, during normal operation and unbalanced grid fault condition is also presented. This study may provide a performance evaluation of different reference current generation techniques and can help in the selection of suitable control during significant grid faults. PSCAD/EMTDC based simulation study is conducted to evaluate the performance of the current generation schemes.
