Abstract: This paper presents design of Fractional Order Fuzzy Logic (FOFL) based UPQC to address power quality issues of load voltage harmonics, current distortions, voltage swell, sag and THD of nonlinear loads, a FOFL based UPQC proposed to tackle Power Quality issues. In this proposed work to make the performance of UPQC more robust by introducing novel control strategy known as FOFL controller. Factional order control strategy called as order change controller. FOFL controller is realized using refined recursive filter. The performance of FOFL based UPQC demonstrated over FOPI based UPQC.The UPQC is used with static and switching nonlinear burdens. It can reduce voltage sag/swell, voltage fluctuations and eliminates harmonics and so on. The proposed controller is implemented by using MATLAB..
