A simulation model of solar array based on Matlab

Established an engineering model of solar array which can reflect the real-time output voltage and current, the maximum power point voltage, the maximum power point current and the maximum power point in any light intensity and temperature of solar arrary. A simulation model is established in Matlab/Simulink and proved the engineering model correctly and reliability. Using the method of Perturbation and Observation(P&O) and Incremental Conductance(INC) track the maximum power point of a solar-array under the reference standard of these output elements, and found out the pursuit gain around the reference standard oscillation and further to validate the model reliability.
