| Abstract: | Firstly, By analyzing and comparing the single index model and the double index model of PV cell, the double index model is more accurate. Secondly, the case that temperature and irradiation has an effect on PV cells can be expediently simulated by the double index model. Finally, based on the perturbation and observation method (P&O), MPPT of PV array is analyzed and realized combining with the Boost DC-DC converter. The simulation results validate the accuracy of the model and the feasibility of the algorithm |
