Model of Series-Parallel Photovoltaic Arrays Using Double-Diode Model and Parallel Computing

Several applications require to estimate the power production of photovoltaic (PV) systems under partial shading conditions. For example, dynamic reconfiguration array connections is needed maximize conditions, which requires estimating generated by PV in several possible configurations. Therefore, a fast and accurate modeling technique perform those calculations practical times with low estimation errors. To address kinds problems, this paper proposes approach based on double-diode model provide high accuracy at voltage irradiance are important for partial-shading analysis. Moreover, proposed designed be implemented parallel processing devices; thus, calculation time much shorter comparison classical serial solutions. The tested terms speed, obtaining satisfactory results. Finally, applicability demonstrated using an application example.
