Performance analysis and validation of intelligent tool based on Brownian random walk-based sand cat swarm optimization algorithm for parameter identification of various solar photovoltaic mathematical models

The photovoltaic (PV) system stands out as a viable energy source due to its environmental friendliness and cleanliness. The conversion rate at which solar power generation is still relatively low due to limitations imposed by advances in PV technology. For PV systems, an appropriate model with precise internal parameters is considerably more crucial to increase conversion efficiency further. Different PV mathematical models, such as single-diode, two-diode, and three-diode, are available to model the PV system. Investigators are interested in assessing the accurate PV model parameters through the experimental voltage-current (I-V) samples or using the manufacturer's specifications. At the same time, the difficulty is in accurately assessing and developing a more trustworthy PV model with well-optimized parameters. To address the parameter estimation of various solar PV models, in this article, a new bio-inspired algorithm called Brownian random walk-based Sand Cat Swarm Optimization Algorithm (SCSOA) named Boosted SCSOA (BSCSOA) is proposed and developed. Along with the Brownian random strategy, chaotic tent drift is also used to enhance the exploration and exploitation of SCSOA, and the proposed BSCSOA is applied to different models to estimate their parameters accurately. The effectiveness of the suggested BSCSOA is compared with other well-known algorithms, including the basic SCSOA, in terms of statistical measures and fitness values. The obtained results demonstrated the superiority of the BSCSOA over the other algorithms for all PV models of the cell and module.
