Orthogonally adapted Harris Hawk Optimization for parameter estimation of photovoltaic models
Extracting parameters and constructing high-precision models of photovoltaic modules through actual current-voltage data is required for simulation, control, and optimization of a photovoltaic system. Because of the application of such problems, the identification of unknown parameters accurately and reliably remains a challenging task. In this paper, we propose an enhanced Harris Hawk Optimization (EHHO), which combines orthogonal learning (OL) and general opposition-based learning (GOBL), to estimate the parameters of solar cells and photovoltaic modules effectively and accurately. In EHHO, OL helps to improve the speed of the HHO method and the accuracy of the solution. At the same time, the GOBL mechanism can increase both diversity of the population and the HHO's exploitation performance. In addition to this, these two mechanisms defend the equilibrium between the exploitation and exploration rates. The results show that accuracy, reliability, and other aspects of this method are better than most existing methods. Thus, EHHO can be used as an effective method for parameter estimation of solar cells and photovoltaic modules. Visit: http://aliasgharheidari.com/
