Results and Discussion This research shows that the most used control method for charging and discharging lead-acid batteries in renewable energy systems with battery energy storage is that of CC–CV. However, this control method requires a long time to charge the battery.
However, during the charging and the discharging process, there are some parameters that are not controlled by the user. That uncontrolled working leads to aging of the batteries and a reduction of their life cycle. Therefore, it causes an early replacement.
The charge control method’s efficiency will depend on the amount of current used for the charging process, the level of the oscillations in the charging current, the charging voltage levels, the charging time, and the fluctuations in the temperature during the charging .
The operational states of the energy storage system affect the life loss of the energy storage equipment, the overall economic performance of the system, and the long-term smoothing effect of the wind power. Fig. 6 (d) compares the changes of the hybrid energy storage SOC under the three MPC control methods.
