Simple and efficient estimation of photovoltaic cells and modules parameters using approximation and correction technique

Abstract

The behavior of solar cells and modules under various operational conditions can be determined effectively when their intrinsic parameters are accurately estimated and used to simulate the current-voltage ( I-V ) characteristics. This work proposed a new computational approach based on approximation and correction technique (ACT) for simple and efficient extraction of solar cells and modules parameters from the single-diode model. In this technique, an approximated value of series resistance ( R s ) was first derived and used to determine the initial value of parallel resistance ( R p ). Later, the final corrected values of R s and R p were obtained by resubstituting their approximated values in a five-loop iteration using the manipulated equations. For rapid evaluation and validation of the proposed technique, a software application was also created using MATLAB program. The correctness and robustness of the proposed technique was validated on five types of solar cells and modules operated at varied temperatures and irradiances. The lowest RMSE value was achieved for RTC France (7.78937E-4) and PVM 752 GaAs (2.10497E-4) solar cell. The legitimacy of ACT extracted parameters was established using a simple yet competitive implementation approach wherein the performance of the developed technique was compared with several state-of-the-art methods recently reported in the literature.

“…Penyelesaian model matematis PV secara numerik akan memberikan kemudahan dan kecepatan. Akan tetapi, ada parameter-parameter yang tidak diketahui dari model PV yang dapat diselesaikan secara analitik, seperti arus foton ( ℎ ), arus saturasi diode ( ), hambatan seri ( ), dan hambatan paralel ( ) [15]. Namun, dalam beberapa penelitian, dan ℎ diselesaikan dengan metode numerik [4], [8].…”

“…Furthermore, the production firms require assurance of the maximum power production from PV power plants. It is well known fact that the energy generation from PV power systems strongly depends on weather conditions, solar irradiance, and temperature [5][6][7]. Besides, these systems unavoidably undergo degradation along with the possible occurrence of electrical faults [8].…”
