Abstract :
Partially shaded conditions are common in all kinds of PV systems. The mismatch phenomenon not only affects the power generated by solar system, but also leads to security problem. Still, under partially shaded conditions, the P-V curve of PV arrays will have the characteristics of multi-summit, which makes the maximum power point tracking very difficult to accomplish. In this paper, the PSO algorithm is applied to the MPPT control algorithm in two different PV structure. Based on establishing the multi-peak model of the PV array under partially shaded condition, the multi-peak MPPT algorithm is designed. Through the introduction of modular structure, the distributed MPPT algorithm is presented. The effectiveness of the algorithm and the advantages and disadvantages of two different algorithms are examined using the MATLAB. At last, the hardware circuit of the control system with man-made partially shaded condition is constructed. The effectiveness and preciseness of the MPPT system is proved by the results of the experiments.
