This research project will design and model the optimal sizing system to store the energy. The model design consists of three phase AC power source, the AC to DC rectifier converter and voltage controller. All these components are combined to form the basic charging system for the battery. In this project, the MATLAB Simulink is employed to study the ESS and the charging curve. The state of charging (SOC) also will be shown in the simulation. The final results will show the simulation on the battery profiles and show all the battery charged results. The results are then explained according to the graphs produced in the simulation.
