An Adaptative OCV and SCC-Based Maximum Power Point Tracking Method for Photovoltaic Panels in the Partial Shading Conditions

In this paper the new maximum power point (MPP) tracking (MPPT) method for a photovoltaic panels (PV) is proposed and tested in real shading conditions in simulations and in the testing environment using multi input dc-dc converter. This is the open circuit voltage (OCV) and the short circuit current (SCC) based method, has very low complexity, so can be implemented in almost every microcontroler. Additionally, by using the correlation function, it is independent of the used photovoltaic panel. Finally proposed method can be implemented in low power maximum power point trackers including the multi-input converters.
