Abstract :
This paper presents a modeling method of photovoltaic (PV) systems and an implementation of the incremental conductance for maximum power point tracking (MPPT) algorithm. The method is used to study the influence of rapidly changing irradiance level concerning performance of photovoitaic systems. A simple circuit model of the dc/dc buck converter connected to the photovoitaic systems is used to easily simulate the incremental conductance MPPT method. The model has been implemented in MAT LAB / Simulink. The simulation results are presented and analyzed to validate that the proposed simulation model is effective for MPPT control of the photovoitaic systems at rapidly changing irradiation condition.
