In smart grids, several types of energy storage technologies are commonly used to manage supply and demand effectively:
Most Common Energy Storage Technologies
- Lithium-Ion Batteries: These are widely used due to their high energy density and efficiency. They are versatile and can be installed in various capacities, making them ideal for both home and grid-scale applications.
- Pumped-Storage Hydropower (PSH): Although primarily used at the grid scale due to geographical constraints, PSH remains the largest form of energy storage globally. It is effective for managing daily and seasonal energy variations.
- Flow Batteries: These are emerging as promising solutions for long-duration storage due to their ability to maintain performance for 25-30 years and adapt to energy storage needs with limited investment.
- Thermal Energy Storage (TES): Systems like hot water or phase change materials store thermal energy, which can be used when needed, helping stabilize grids by providing heat during low renewable production periods.
Role in Smart Grids
- Smart Grid Integration: These technologies are integrated into smart grids to balance supply and demand in real-time, ensuring grid stability and reliability.
- Demand Response: Energy storage systems enable consumers to adjust energy use based on availability, promoting efficient energy management through dynamic pricing and incentives.
- Smart Distribution Networks: Advanced technologies are used to monitor and manage energy distribution, ensuring efficient use of stored energy to mitigate grid bottlenecks and enhance system resilience.
