Under partially shaded conditions, several local maximum power points (MPPs) are found in the power-voltage curve of PV modules. The PV characteristics change with multiple MPPs, so the actual MPP tracking becomes a difficult task. Conventional methods for tracking the MPP of PV modules under partially shaded conditions cannot be quickly find the actual MPP. Based on the p-n junction semiconductor theory, we develop a multipoint direct-prediction method for directly estimating multiple MPPs for power tracking of PV modules under partially shaded conditions. The proposed method is a new and simple approach with a low calculation burden. The experimental results demonstrate that the proposed method helps in the optimization of the MPP control model in PV modules. © 2012 IEEE.maximum power point; multipoint direct-prediction method (MPDP method); non-uniform irradiation; partially shaded irradiation; Photovoltaic modules[SDGs]SDG7Control model; Conventional methods; Environmental conditions; Generation systems; Irradiation conditions; Local maximum; Maximum power point; Maximum Power Point Tracking; Multipoint; Non-uniform irradiation; P-n junction; Photovoltaic modules; Power tracking; Power-voltage; PV modules; Semiconductor theory; Simple approach; Solar shadings; Estimation; Exhibitions; Semiconductor junctions; Solar power generation; Irradiationconference paper10.1109/EnergyCon.2012.6347740
