In This paper power quality is improved in microgrid systems by using a FACT device named as IUPQC i.e. Interlinked Unified Power Quality Conditioner. IUPQC basically modified controller from normal UPQC Controller and small difference is that control techniques only. IUPQC Contained Series power filter (SPF) and Shunt power filter connected back to back end with common dc link capacitor. Help of Fuzzy logic technique in both UPQC and IUPQC Controller, we can reduce the voltage sag or voltage swell interruptions. Compared to UPQC, IUPQC gives fast and better result. Simulink models and results are done in MATLAB R2016A Software.

Flexible Alternating Current Transmission (FACT), (IUPQC), and Series Power Filter (SPF), Fuzzy Logic Controller (FLC).
