Abstract: This paper presents design of FOPI based UPQC to address power quality issues of load voltage harmonics, current harmonics, voltage swell, sag and THD of nonlinear loads, a FOPI based UPQC proposed to tackle Power Quality issues. The UPQC was wide studied by several as associate ultimate methodology to boost power quality of electrical distribution system. It is the combination of Series APF and Shunt APF. In this proposed work to make the performance of UPQC more roust by introducing novel control strategy known as Fractional Order PI (FOPI) controller. Factional order control strategy called as order change controller. FOPI controller is realized using refined recursive filter. The performance of FOPI based UPQC demonstrated over PI based UPQC. The UPQC is used with static and switching nonlinear burdens.The proposed controller is implemented by using MATLAB/Simulink,
