Abstract
Tracking the maximum power point of a PV system is essential for both stand-alone and grid-connected PV systems to ensure that the solar cells can produce the highest power for different environmental conditions. This paper proposes the maximum power point tracking for a PV stand-alone system using incremental conductance method. The control principle of the proposed method uses the duty cycle adjustment via the buck converter to obtain the maximum power output of stand-alone PV system. The control performance was confirmed by MATLAB/Simulink simulation and experiment results. It has been demonstrated that the maximum power point tracking of stand-alone PV system by incremental conductance method can follow the peak power point in all environmental changes.
