• Flywheels: These mechanical devices store energy in the form of kinetic energy and can discharge it rapidly.
• Pumped Hydro Storage: Utilizing gravitational energy, water is pumped to a higher elevation and released to generate power when needed.

2. Power Conversion System

The power conversion system (PCS) is crucial for the functionality of energy storage systems. It manages the flow of electrical energy between the energy storage device and the grid. Key functions include:

• Inversion: Converting DC (direct current) from batteries into AC (alternating current) for grid compatibility.
• Control: Monitoring and controlling the charge and discharge cycles for efficiency and longevity.
• Protection: Safeguarding the system from electrical faults and ensuring operational safety.

3. Battery Management System

The battery management system (BMS) is essential for maintaining the health and performance of battery packs. Its main functions include:

• Monitoring: Continuously checking the state of charge (SoC) and state of health (SoH) of each cell within a battery pack.
• Balancing: Ensuring all cells are evenly charged and discharged to extend the lifespan of the battery.
• Safety: Including safety measures such as over-voltage and under-voltage protection, thermal management, and fault detection.

4. Thermal Management System

The thermal management system plays a critical role in ensuring the optimal operating temperature for energy storage components. This system can include:

• Cooling Systems: Devices designed to dissipate heat generated during energy storage and discharge.
• Heating Systems: Used in colder climates, these systems ensure that batteries operate efficiently at optimal temperatures.

5. Control Systems

The control systems are integral for system operation, coordinating all components to function as a unified entity. In this context, control systems include:

• Automation: Automating responses based on grid signals and user-defined parameters.
• Data Management: Collecting and analyzing operational data to optimize performance.

Applications of Energy Storage System Components
