Hybrid controller-based solar-fuel cell-integrated UPQC for enrichment of power quality

Abstract

Abstract A fuzzy-integrated sliding mode-based hybrid controller (FISMHC) attributed to unified power quality conditioner (UPQC) was proposed in this study through implementation with solar integrated to fuel cell through incorporation of UPQC within sequence designed for active power filters of series and shunt configurations under shared structure of DC-link capacitor deployment. Furthermore, the proposed scheme with FISMHC UPQC (U-FISMHC) can achieve the following goals: (i) maintaining constant DC-link voltage in the absence of peak overshoot, (ii) performance evaluation under varied fluctuations in grid voltage, and (iii) decreasing source current and load voltage harmonics. In addition, the study compares U-FISMHC performance with distribution case over specific test conditions such as supply voltages, solar irradiation, and conditioned loads to demonstrate the proposed controller’s superior performance.
