Journal ArticleDOI
Comprehensive Approach to Modeling and Simulation of Photovoltaic Arrays
TL;DR: In this article, the authors proposed a method of modeling and simulation of photovoltaic arrays by adjusting the curve at three points: open circuit, maximum power, and short circuit.
Proceedings ArticleDOI
Modeling and circuit-based simulation of photovoltaic arrays
TL;DR: An easy and accurate method of modeling photovoltaic arrays using information from the datasheet is presented and the model is validated with experimental data.
Journal ArticleDOI
Voltage regulation of photovoltaic arrays: small-signal analysis and control design
TL;DR: In this article, the voltage regulation problem is addressed with a detailed analysis that starts with the modelling of the PV array and the converter, followed by study, design, simulation and practical experiments of three closed-loop control strategies for the buck converter.
Proceedings ArticleDOI
Analysis and simulation of the P&O MPPT algorithm using a linearized PV array model
TL;DR: In this paper, the performance of the perturb and observe (P&O) maximum power point tracking (MPPT) algorithm is improved when the electronic converter is correctly controlled.
Journal ArticleDOI
Dynamic analysis of the input-controlled buck converter fed by a photovoltaic array
TL;DR: This paper deals with the analysis and the control of the buck converter with constant output voltage and variable input.
