Comprehensive view of community energy storage

Community energy storage refers to the technology of storing electricity in a centralized or distributed manner at the community level for emergency use. The principle is mainly to use energy storage devices such as batteries and flywheels to store energy when there is excess electricity and release energy during peak electricity demand, thereby achieving energy balance and optimized utilization. Community energy storage is applied in residential communities, commercial areas, industrial parks and other places, providing stable and reliable electricity while effectively solving the volatility and intermittency problems of renewable energy generation.

The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.

The principle of electric energy storage: The basic principle of electric energy storage is to convert electrical energy into other forms of energy for storage, and then convert the stored energy back into electrical energy when needed. Electric energy storage methods include pumped storage, battery storage, flywheel storage, compressed air storage, and gravity storage. one Pumped Storage ① Energy Conversion: During periods of low electricity demand (such as nighttime), excess electricity is used to drive water pumps, which pump water from the lower reservoir to the upper reservoir for storage. During this process, electrical energy is converted into the potential energy of water for storage. ② Energy release: During peak electricity demand periods (such as during the day), the gates of the upper reservoir are opened to allow water to flow from higher to lower levels. The potential energy of the water is converted into mechanical energy through turbines and generators, which is then converted into electrical energy to supply the power grid. two Compressed air energy storage ① Energy conversion: During periods of low electricity demand, excess electricity is used to drive compressors, compressing and storing air in underground caves or pressure vessels. this.
