Instantaneous DQ method for UPQC with PI and fuzzy controller

This paper shows the analysis of DQ method for power conditioning with two different controller PI and Fuzzy. The Dq method is more easy to implement in comparison with Instantaneous PQ theory in terms of calculation and complexity. It take care of harmonics, sag/swell and unbalanced system. All the simulation results are based on Simpowersystem by Matlab/ Simulink are presented and effectively verified the proposed control strategy.
