Modelling and simulation of maximum power point tracking of photovoltaic system in Simulink model

Due to world energy crisis and growing demand for energy as the conventional energy sources have become increasingly unable to meet the world demand for the energy. This paper present the design and simulation for maximum power point tracking for photovoltaic system which include a high efficiency dc-dc boost converter with a modified incremental conductance algorithm. The converter is able to draw maximum power from the PV panel for a given solar insolation and temperature by adjusting the duty cycle of the converter. The modelling procedure for the circuit model was presented using MATLAB/Simulink Sim-power. The MPPT system has been tested with solar panel ICO-SPC 100w module under various operating conditions. The obtained results have proven that the MPP is tracked even under sudden change in environmental conditions and loading level.
