  • Department of EEE, KL University, Vaddeswaram, Guntur District - 520002, Andhra Pradesh, India


Background/Objectives: The main ideology behind this paper is to design a Fuzzy Controller based Photo Voltaic-Active Power Filter (PV-APF) combinational system for alleviation of Current Harmonics. Methods/Statistical Analysis: The efficiency of PV module can be elevated by operating at Maximum Power Point (MPP) to achieve utmost power output. Hence, Maximum Power Point Methods (MPPT) methods. Here the Voltage Source Converter would act as active power filter compensating the current harmonics that are produced in 3-Ф 3-wire system there by the system power quality can be improved. Also, in this paper comparison is performed among fuzzy and PI controllers. Findings: The unified system is simulated in MATLAB/SIMULINK software based on simulation results obtained, we can able to conclude that compared to PI the total harmonic distortion of Fuzzy Controller is reduced to 3.68%. Application/Improvement: The THD value obtained from Fuzzy Controller is accurate. Hence Fuzzy Controller based PV-APF System is used for Alleviation of Current Harmonics.
