Comprehensive modeling of photovoltaic characteristics based on simulation

Abstract

Photovoltaics have the characteristic of being an effective representation of the nonlinearity contained in the panels, this is very important in achieving a renewable energy supply system. There have been several models for photovoltaics proposed in several literatures to analyze their characteristics, but a comprehensive analysis still needs to be carried out to obtain a simple model in PV modeling so that manufacturers can easily implement it. Based on empirically derived one, two and three diode circuit modeling. However, an extensive model analysis of the unique characteristics for modeling PV at the maximum power point (MPP) has not been carried out, therefore researchers will conduct a comprehensive review to obtain a model that is suitable for manufacturers. Based on the IEC standard EN 50530, the absolute error around the MPP must be ± 1%. Therefore, this paper proposes an empirically based analysis model regarding the accuracy of PV models to reconstruct the characteristics of PV panels. Limitations of PV modeling were identified based on simulation results obtained with MATLAB and characteristic indices, besides that this paper also provides input for future research directions.
