The battery energy storage system (BESS) as a flexible resource can effectively achieve peak shaving and valley filling for the daily load power curve. However, the different load power levels have a difference.
Applications: The energy released during discharging can be used for various applications. In grid systems, it helps to stabilize supply during peak demand. In electric vehicles, it powers the motor, allowing for travel. The efficiency of charging and discharging processes is affected by several factors:
How to avoid overcharging and overdischaging of energy storage system?
In avoid overchargng and overdischaging of the energy storage system. Despite the fact that constant- discharging, other methods such as FLC or MPC have shown better performances. The main benefits keeping the battery SOC within secure limits. Moreover, the reduction o the investment cost in energy storage capacity and the life expectancy increase.
Modern battery management systems monitor this process to prevent overcharging, which can lead to safety hazards. When energy is needed, the battery enters the discharging phase. This process reverses the chemical reactions that occurred during charging. Energy Release: During discharging, lithium ions move back from the anode to the cathode.
As technology advances, the efficiency of charging and discharging processes will continue to improve. Innovations such as fast charging, solid-state batteries, and advanced battery management systems are on the horizon, promising to enhance the performance and safety of energy storage batteries.
Why is energy storage important?
Energy storage has become a fundamental component in renewable energy systems, especially those including batteries. However, in charging and discharging processes, some of the parameters are not controlled by the battery's user. That uncontrolled working leads to aging of the batteries and a reduction of their life cycle.
How does fuzzy logic control of energy storage systems work?
3.1.2. Fuzzy Logic Control of Energy Storage Systems in Grid-Connected Applications ] divided the charging process into two stages. At the first stage, they implemented a FLC to determine the start charging time and to prevent overcharging or insuf ficient battery charging. At the second stage, they used the normal charging method.
