Power from PV is fed to the grid system with a single-stage single-phase inverter. The proposed MPPT method can realize the maximum power using the fill factor from the datasheet parameters of PV panel combined with measurements of open circuit voltage (V <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">oc</sub> ) and short circuit current (I <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">sc</sub> ). The non-iterative MPPT algorithm generates power reference used in the control. The single-phase grid connected inverter used double band hysteresis current controller. The converter power circuit is modified to execute V <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">oc</sub> and I <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">sc</sub> measurements. The proposed method was confirmed by simulation using MATLAB/Simulink. The simulation results under steady state and changing irradiance show that the maximum power from PV can be fed to the grid with THDi = 2.9 % and PF = 0.95.Read More
