[IEEE 2019 2nd International Conference on Power Energy, Environment and Intelligent Control (PEEIC) - Greater Noida, India (2019.10.18-2019.10.19)] 2019 2nd International Conference on Power Energy, Environment and Intelligent Control (PEEIC) - Power Quality Enhancement of Soft Computing FLC MPPT Based Standalone Photovoltaic System

摘要： Single phase system has been secured with Photovoltaic system based on Fuzzy Logic Control based perturbed & observed (P&O) maximum power point tracking phenomenon with active power filter (APF) connected to a nonlinear load. The conventional Perturbed & Observed algorithm is used to achieve maximum power output from Photovoltaic array, Proportional Integral controller with positive sequence detector phase locked loop(PLL) synchronization are implemented to generate reference current. It is emplyed to generate switching signal for VSI in hysteresis band current controlled (HBCC). DC link of PWM converter is controlled with switch controlled of VSI inverter. In proposed work minimize harmonic distortion present in source current due to power electronic based nonlinear load. Total current harmonic distortion (THD) is reduced by shunt active power factor and power factor improve after compensation reactive power supplied by system reduce and active power of system increase. The system designed with MATLAB/SIMULINK 2015(a) platform.
