Control Management System of a Lithium-ion Battery Charger Based MPPT algorithm and Voltage Control

Solar energy is considered as one of the main renewable energy sources, even though the energy produced by a photovoltaic array is variable and non-linear depending on the changes in irradiation and in temperature. The changes do not allow the system to extract the maximum power from a PV array in which numerous features must be fitted, for instance, the efficiency, the stability and the accuracy. In power solar systems, preserving the lifetime of materials and extracting the maximum power from PV panels are all primordial findings in order to reduce the investment costs. In this work, the required features are achieved by controlling a dc/dc boost converter with two different strategies of control i.e., the maximum power point tracking (MPPT) INC algorithm to benefit as much as possible from solar irradiation and the PI control to secure the battery from the overloading situation. The results of this approach are simulated and analyzed by MATLAB/Simulink environment in order to test the control management algorithm.
