Abstract

In this paper, Fractional Order Fuzzy Logic (FOFL) controller based UPQC (Unified Power Quality Conditioner) is proposed for addressing the power quality problems such as current distortion,voltage Swell, Sag, and THD of nonlinear loads in distribution power system. The goal is to make UPQC’s operation more aggressive by implementing a new control strategy known as FOFLC. As an order change controller, it’s known as an order control strategy.The FOFL controller is made using a refined recursive filter.In this proposed paper, a FOFL controller based UPQC is projected to address the well-known power quality issues, popularly known as harmonic compensation and voltage sag/swell and Regulation of \(V_{DC-Link}\) in terms of Dynamic Performance of the system.The performance of UPQC is demonstrated on power distribution system consisting of nonlinear loads.The UPQC with FOFL controller is quite capable of mitigating power quality issues compared to UPQC with FOPI controller.The proposed controller is implemented using MATLAB/Simulink.
