Abstract

In this work, a hybrid algorithm of Levenberg-Marquardt and empiric analytic method is proposed to solve the recurring convergence problem that occurs during the module parameters extraction with the iterative method. The proposed method aims to avoid divergence and a long computation time due to the improper initial value. Elsewhere, LTSpice photovoltaic cell model is developed to simulate the extracted parameters in sub-Saharan outdoor conditions. The LTSpice model with it virtual component is expected to facilitate the understanding photovoltaic module behavior under these conditions. Measurements performed with VSP50P-12V polycrystalline module and compared to simulation results show the accuracy of the hybrid method and the ease of LTSpice model. The hybrid algorithm with RMSE value of 0.9% while correlation one is greater than 97% for simulated irradiation is more accurate than the Levenberg-Marquardt algorithm.

  

Key words: Cell model, LTSpice model, Levenberg-Marquardt algorithm, empiric analytic.
