Parameter extraction of solar cells was performedusing three optimization methods. Parameter extraction from I–V characteristics containing errors is inconclusive. Newton method is preferred for parameter extraction of measurements with small errors. Reliable parameter are obtained for small measurement errors of I–V characteristics. Abstract
In , hybrid of SA and Levenberg–Marquardt (LM) algorithm has been used for parameter estimation of solar PV cells via experimental I – V data. Again, RMSE is the objective function. Single diode model for PV cells has been used. In LM, damping factor plays crucial role in convergence behaviour.
In cases where experimental I – V data are used for parameter estimation of solar PV cells, using data sets with larger number of I – V data points can lead to results of higher accuracy, although computational time increases. The appropriate objective function for PV cell parameter estimation problem, depends on the application.
Analytical methods for parameter estimation of PV cells In a large number of research works, analytical methods have been used to extract model parameters of PV cells. In this section, those research work are classified based on their used PV cell model and will be analysed. 3.1.1. Analytical methods for parameter estimation of single diode models
For determining PV cell model parameters, different methodologies have been proposed in the literature. All those methodologies can be classified into three main categories. The first category of methodologies include analytical methods that provide formulations for deriving model parameters based on datasheet information or I – V curve data.
The proposed adaptive DE has been applied to parameter estimation problem of solar PV cells. Parameter estimation has been done for single diode model. Both Synthetic and experimental data have been used. RMSE defined by (39) is the objective function. The decision variables are bounded in the ranges below.
