Performance Evaluation of Analytical Methods for Parameters Extraction of Photovoltaic Generators

Abstract

This paper presents a succinct exploration of several analytical methods for extracting the parameters of the single-diode model (SDM) of a photovoltaic (PV) module under standard test conditions (STC). The paper investigates six methods and presents the detailed mathematical analysis leading to the development of each method. To evaluate the performance of these methods, MATLAB-based software has been devised and deployed to generate the results of each method when used to extract the SDM parameters of various PV test modules of different PV technologies. Similar software has also been developed to extract the same parameters using well-established numerical and iterative techniques. A comparison is subsequently made between the synthesized results and those obtained using numerical and iterative methods. The comparison indicates that although analytical methods may involve a significant amount of approximations, their accuracy can be comparable to that of their numerical and iterative counterparts, with the added advantage of a significant reduction in computational complexity, and without the initialization and convergence difficulties, which are normally associated with numerical methods.

A Compact Mathematical Modelling for Performance Evaluation of PV Module considering Single-Diode M odel

“…We have compared the simulated results of the parameters η, R s and R sh with the published and experimental results available in the literature (14)(15)(16)(17) for various solar modules at STC (Table 2 ) with good agreement for η and R s . Table 2 results confirm the validity of the proposed analytical models of the parameters η, R s and R sh .…”

“…A compact analytical model for these resistances is essential to evaluate the performance and degradation of the cell in outdoor environment. Researchers have mostly calculated the value of R s and R sh by approximating the reciprocal of the slope of the https://www.indjst.org/ I-V curve at the open circuit and short-circuit-points (14) . In this paper, we have proposed the mathematical expressions for R sh and R s by considering maximum power point technique and assuming maximum power remains constant with voltage at V m .…”

Study on Battery Charging Converter for MPPT Control of Laser Wireless Power Transmission System

“…In the parameters of the laser PV module, I sc and V oc were set as the short-circuit current and open-circuit voltage values measured in the experiment, and the R s , R sh , and n values were extracted by the trial and error method through the simulation model in Figure 15b. In order to extract more accurate parameters of the laser PV module using an optimization algorithm, the method mentioned in Sheng and Anani's articles can be applied [17,18]. The accuracy of the simulation model compared with the experimental data of the module mentioned in Section 2 is shown in Figure 16.…”

Renewable Energy and Energy Storage Systems

“…The cost was inversely proportional to the required reliability of the power supply, as measured in outage hours. Anani and Ibrahim [58] presented a comprehensive mathematical analysis and comparison of the performance of commonly reported analytical methods for parameter extraction of a PV module's single-diode model under standard test conditions (STC). Using numerical and iterative methods, the values of reference parameters were extracted and compared with the parameters extracted using the various models.…”
