A novel MPPT method for photovoltaic application under partial shaded conditions

摘要

Maximum Power Point Tracking (MPPT) gains much attention as an important optimisation field for the photovoltaic (PV) systems. Under Partial Shading Conditions (PSC), the Power-Voltage (P-V) curve of a PV array exhibits multiple picks. Therefore, the conventional algorithms, regardless of their simplicity, may fail to track the Maximum Power Point (MPP). However, the non-conventional algorithms, despite their efficiency on tracking the global pick, are more difficult to implement since they need more hardware and software requirements. Thus, literature proposes many variants of non-conventional algorithms that improve their simplicity and efficiency.
