Optimal battery charge and discharge control scheme under solar power inflow

This paper presents an optimal battery working scheme for charging and discharging batteries under solar power inflow. A modified Kinetic Battery Model (KBM) was employed to model the battery as a dynamic system. Using a solar panel as the battery charging source under different solar intensities, an optimal control problem was formulated to maximize the final battery energy level while completing required technical tasks. The optimal solution was derived based on the appropriate constrains and boundary conditions. Preliminary numerical and experimental results have shown that the developed battery control scheme can meet the task requirements while maximizing the stored energy level of the battery.
