| Abstract: | The output power of the photovoltaic (PV) array changes with the change in external environment and load. Therefore, maximum power point tracking (MPPT) technology is needed to maximize the efficiency of the PV device. At present, existing methods have realized MPPT to some extent. However, the tracking precision and speed remain to be improved. In the current paper, the chaos search theory is first applied on the MPPT technology of the PV system. The chaos search algorithm based on dual carrier increases the adequacy of chaos search and overcomes the blindness of the traditional chaos search, thereby improving the search efficiency. Comparative tests show that the proposed method can quickly and accurately track the step response, and can obtain better optimization results. The simulation and experimental results show the effectiveness and good performance of the proposed method. |
