Popis: | The partial shading (PS) of the photovoltaic (PV) array is a major problem for the PV systems. Therefore, it is necessary to extract the global maximum power point (GMPP) under partial shading. In this paper, we propose a simple method to find the GMPP. This method scans the P–V curve and memorizes all the peaks in order to get the global peak. Next, we control a boost DC–DC converter to extract the GMPP from the PV system. In addition, this Method allows following the dynamic GP under variant SPs with less oscillations around the stable state compared to the existing works. |
