The main types of energy storage systems used for peak shaving include:
- Battery Energy Storage Systems (BESS):
- BESS are the most common and effective method for peak shaving. They store energy during off-peak periods and discharge it during peak demand times, reducing the strain on the grid and lowering demand charges.
- BESS can be integrated with renewable energy sources such as solar and wind power, enhancing grid stability and supporting a sustainable energy future.
- Hydrogen Storage Systems:
- Although not as widely discussed in the context of peak shaving as BESS, hydrogen storage can also be used by converting excess energy into hydrogen, which can later be used for power generation during peak times. However, this technology is less commonly mentioned for peak shaving compared to battery systems.
- Flywheel Energy Storage Systems:
- Flywheels can store energy mechanically and release it quickly during peak times. However, they are generally used for short-term power quality applications rather than prolonged peak shaving.
- Compressed Air Energy Storage (CAES):
- CAES systems store compressed air in underground caverns and can release energy by expanding the air through a turbine. While they are used for energy storage, they are less commonly applied for peak shaving due to geographical limitations.
- Other On-Site Generation Systems:
- Systems like natural gas generators or combined heat and power (CHP) plants can provide supplemental power during peak periods. Though they are not strictly “storage” systems, they contribute to peak shaving by reducing grid demand.
In practice, Battery Energy Storage Systems (BESS) are the most versatile and widely used technology for peak shaving due to their flexibility, scalability, and ability to integrate with various energy sources.
