Energy storage systems play a crucial role in managing peak demand by storing electricity during periods of low demand and releasing it during peak periods. The main types of energy storage systems used for peak demand management include:
- Battery Energy Storage Systems (BESS):
- These are widely used due to their flexibility and rapid response capabilities. BESS can store energy from both the grid and renewable sources, such as solar or wind, and release it during peak hours to reduce strain on the grid.
- Pumped Hydro Storage:
- This traditional method involves pumping water from a lower reservoir to an upper reservoir during off-peak hours, using off-peak electricity. During peak hours, the water is released to generate electricity, providing a reliable source of power.
- Thermal Energy Storage:
- This system involves storing thermal energy for use during peak periods. It can be used for both heating and cooling applications, providing flexibility in managing peak demand.
- Grid-Level Energy Storage:
- This category includes large-scale storage systems designed to stabilize the grid, ensure frequency and voltage stability, and prevent blackouts during peak demand periods.
These systems are essential in ensuring grid stability, reducing reliance on fossil fuels during peak hours, and integrating renewable energy sources into the grid effectively.
