Parameter identification of the lead-acid battery model

The lead-acid battery, although known since strong a long time, are today even studied in an intensive way because of their economic interest bound to their use in the automotive and the renewable energies sectors. In this paper, the principle of the lead-acid battery is presented. A simple, fast, and effective equivalent circuit model structure for lead-acid batteries was implemented. The identification of the parameters of the proposed lead-acid battery model is treated. This battery model is validated by simulation using the Matlab/Simulink Software.

Comparison between different control methods of a solar energy conversion system

In the context of renewable energy, this study treats the case of the conversion of solar energy, which is one part of non pollutant energy, to electrical one. Maximizing methods of the generated power is discussed in this paper. Thus, the case of solar panel is studied and a comparison between the ‘perturb and observe’ control method and the ‘incremental conductance’ control method in order to maximize the output power are given, analyzed and discussed.
