As a result, the further proposed variable step algorithm of Versoria has a fast tracking performance, which solves the problem of slow convergence speed, reduces its fluctuation range, and solves the consistency of tracking stability and convergence speed. Therefore, two disturbance factors, illumination intensity and ambient temperature, are considered, and the following formula can be obtained: The output characteristics of photovoltaic panels are influenced by a variety of factors, and the light intensity and temperature that have the greatest impact on the panels are selected for analysis. The main role of the fuzzy controller is to adjust the output control signal to stabilize the PV system at maximum power output, as mentioned above. 1 (2014): 96-101. Copyright © 2020 Bo Sun et al.

Modeling, Simulation and Implementation of PV Cell/Modules Using PSpice Messaadi Lotfi, Dibi Zohir Batna University, Advanced Electronic Laboratory (LEA), 05000 Batna, Algeria (Received 10 December 2016; revised manuscript received 12 January 2017; published online 30 June 2017) This paper presents a Spice model of a photovoltaic cell. PV module manufacturers often use this model to give technical characteristics of the modules. The key to the design of a photovoltaic controller is the design of control algorithm. Based on this study a conclusion is drawn with comparison with ideal diode. The experimental results obtained, exhibited a good agreement with the simulated data . An improved equivalent impedance matching MPPT algorithm is proposed in , which is based on the principle of adaptively matching PV output characteristics with system impedance by changing system parameters. Also, the maximum power point varies with light intensity and ambient temperature, which verifies the correctness of the model. Its simulated light intensity signal page is shown in Figure 11. Optical Modeling and Simulation of Thin-Film Photovoltaic Devices provides readers with a thorough guide to performing optical modeling and simulations of thin-film solar cells and PV modules.

That is why advanced algorithms are very important for PV power generation systems. In this research Simulink based modeling is explored for the design and simulation of a solar charger (Tarak, et. These advantages enable the PV solar cells to achieve high conversion efficiency with a relatively low cost. Under changing external conditions, it is necessary to constantly change the duty cycle size to track the maximum power output point of the PV cell [14, 15], which requires fast-tracking capability and good convergence of the MPPT algorithm. Assuming the infinity of the parallel resistance Rsh, regardless of its effect, the following formula can be obtained: Next, we solve for equation (3). Ning, and Z.

Obviously, the change in light intensity has a big impact on the maximum output power of photovoltaic cells, as shown in Figure 3, and the maximum output power of photovoltaic cells increases significantly with the increase in light intensity. When the light intensity changes, the I-U output curve of the photovoltaic cell is as shown in Figure 5. The component parameters of the BOOST circuit simulation model are shown in Table 2. In order to reduce the static error, a genetic factor is proposed to sum up the historical error to effectively improve the tracking stability.

AZZOUZI}, year={2014} } M. AZZOUZI Published 2014 Solar energy is one of the most important types of renewable energies. Rs is the total series resistance formed by the resistance of the material body, the thin layer resistance, the contact resistance of the electrode, and the resistance of the conductive current of the electrode itself, and the resistance value is usually less than 1 Ω. Rsh is the leakage current caused by the incomplete part of the PN junction formation, called parallel resistance, and the resistance value is usually several thousand ohms. The photovoltaic controller achieves maximum power point tracking by adjusting the duty cycle, so that the voltage of the DC/DC circuit changes, and the PV panel always maintains maximum power output. 2 : Equivalent Model of Single-Diode Photovoltaic Cell.

Figure 12(b) shows that the fuzzy control algorithm tracks the maximum power point at 70 ms in the second stage, and the variable step algorithm of Versoria tracks the maximum power point at 56 ms. An ideal PV cell may be considered as a current source in parallel with a diode. Our module consists of 36 cells, so we have 6 blocks of 6cells. Many models of solar cell had been Models and simulations play an important role in the design and optimization of PV systems. 1–2 (September 3, 2008): 391–400. But, the two algorithms need to be reasonably set to switch values; otherwise, the tracking speed and stability are easily affected.

Figure 12(a) shows that the fuzzy control algorithm, and the tongue-and-groove variable-step algorithm simultaneously tracked the maximum power point at 3 ms in the first stage, and the fuzzy fluctuation of the fuzzy control algorithm is between 191.3 and 192.9 W. The variable step algorithm of Versoria has a stable fluctuation range of 192.0∼192.9 W. In the first stage, the variable step algorithm of Versoria has better convergence, and the tracking speed is comparable. or. In summary, the variable step algorithm of Versoria can achieve maximum power point tracking, which has higher tracking speed and better convergence than the fuzzy control algorithm. The algorithm is also instructive for solving practical problems of MPPT-related projects. "Improving the efficiency of polycrystalline solar panel via water immersion method." The shape of the Versoria function is determined by the three parameters α, β, and γ, where α represents the size of the translation of the Versoria function up and down along the y-axis, and the larger the α, the greater the translation of the function upward; β indicates the width between the highest point of the Versoria function and 0, and the larger the β, the wider the function width; γ represents the “fatness” at the peak of the Versoria function, and the larger the γ, the steeper the function graph peak and the more “thin” “the function.” α determines the tracking speed of the algorithm, and β and γ determine the stability at the end of tracking.
