Battery Energy Storage Systems (BESS) and Need for Electrical Energy
Conservation
Battery Energy Storage Systems (BESS)
1. Definition and Purpose:
1. Energy Storage Systems (ESS) are designed to store energy for use during peak periods,
enhancing the reliability of power systems, encouraging renewable energy sources
(RES), and avoiding the challenges of sudden load variations in RES generation. They
help provide frequency control, improve network reliability, and ensure system
flexibility.
2. Types of ESS:
• - Mechanical: Pumped Hydro Storage (PHS), Flywheels (FES), Compressed Air Energy
Storage (CAES).
• - Electrochemical: Includes batteries like Lithium-ion, Lead Acid, Nickel-Cadmium, and
Vanadium Redox.
• - Electrical: Supercapacitors, Superconducting Magnetic Energy Storage (SMES).
• - Thermal: Molten salts, solar fuels.
• - Chemical: Hydrogen or synthetic natural gas.
3. Applications:
• - Grid Applications:
• - Peak Shaving: Reducing load during peak demand.
• - Load Leveling: Balancing energy supply and demand.
• - Power Reserve: Maintaining uninterrupted power supply.
• - Integration of RES for voltage and frequency regulation.
4. Characteristics:
• - Technical Parameters:
• - Cell voltage, specific energy (Wh/kg), specific power (W/kg), energy density
(kWh/m³), power density (kW/m³), efficiency, working temperature, lifetime
cycles, depth of discharge, and cost.
• - Performance Comparison: Different battery technologies (Lead Acid, Li-ion, Ni-Cd, etc.)
vary in these parameters, making them suitable for specific use cases.
