Over the last few decades, researchers have paid attention to finding an effective and efficient metaheuristic algorithm that can determine ideal parameters for PV models. In this study, TDM’s nine unknown parameters, we will examine efficacy of a recently proposed called light spectrum optimizer (LSO). To further enhance effectiveness LSO in estimating those new improved variant ILSO is developed. This employs conjunction with two newly developed update systems improve its exploration exploitation operators. We compare best fitness value, worst average fitness, standard deviation, p-value returned by Wilcoxon rank-sum test obtained three published competitors when Photowatt-PWP201 module RTC France solar cell. The experimental findings show most efficient.

Published: July 23, 2024

Abstract Parameter prediction for PV solar cells plays a crucial role in controlling and optimizing the performance of modules. In this study, parameter four‐diode model was carried out using Improved Grey Wolf Optimization (IGWO) algorithm, which builds upon (GWO) algorithm. The parameters required were optimized based on predefined objective function. Subsequently, obtained data compared with from RTCFrance Solar Cell to validate accuracy reliability optimization results. evaluation results revealed that Sum Square Error (SSE) values PSOGWO, AGWOCS, GWOCS, GWO 3.96E‐05, while MSE value IGWO 3.6309E‐05. These findings clearly demonstrate proposed algorithm outperforms other algorithms used minimized SSE values. This study emphasizes importance performance, it contributes thefield by introducing novel model. algorithm's superior as demonstrated through extensive testing comparison existing algorithms, validates its efficacy accurately predicting cell

Improved reference condition independent method for output performance estimation of PV modules under varying operating conditions

Journal of Renewable and Sustainable Energy, Journal Year: 2024, Volume and Issue: 16(2)

Published: March 1, 2024

Traditional methods for estimating output property of the photovoltaic (PV) modules are strongly influenced by selection reference condition and transforming equations, which determine calculated physical parameters under real operating conditions. The differences in carrier transport properties PV cells varying conditions, such as number velocity minority carriers at junction edge their recombination speed, lead to large deviations estimation characteristics, especially low irradiance To enhance accuracy performance estimation, we propose an improved method that is independent condition. This eliminates impact conditions improves transformation equations all levels. Transformation single diode model established different intervals based on dependence parameter temperature. Especially range, effects temperature considered each equations. optimize unknown artificial hummingbird algorithm used fit experimental I–V data. results six types a wide range verify effectiveness proposed method. offers immediate benefits, including independence from more precise relationship between environmental factors properties. Comparing traditional Laudani, demonstrates superior capability characteristics accurately identifies maximum power point various significant value engineering applications.

A MATLAB/GUI for Photovoltaic Modules Performance Simulations Based on Two-Diode Model

Published: May 15, 2023

Manufacturers of photovoltaic modules do not provide all the information necessary to predict their performance under different climatic conditions. This forces development mathematical models behavior and application methods for calculation associated parameters. A toolbox called PVMSim implemented in MATLAB/GUI is proposed this paper. PVMSIm provides allowing simulation modules. two-diode model used represent effect irradiance temperature on V-I V-P characteristic curves.
