How BESS Reduces Costs and Increases Efficiency?

What is a Battery Energy Storage System (BESS)?

A Battery Energy Storage System (BESS) is a device that converts electrical energy into chemical energy and stores it in a battery, and then converts the chemical energy back into electrical energy when needed. It’s like a “power bank” that can store excess electricity and release it during peak demand periods or when the grid is unstable, thereby improving energy efficiency and grid stability.

How does BESS work?

BESS operates relatively simply. When grid power supply is excessive or generation cost is low, electrical energy is converted into DC power by an inverter and input into the battery for charging. When grid power demand increases or generation cost is high, the chemical energy in the battery is converted into AC power through an inverter and supplied to the grid.

Power and Energy Ratings of BESS

The power and energy ratings of BESS can be customized according to different application scenarios. Power determines the maximum amount of electricity that the system can output or absorb per unit time, while energy represents the maximum amount of electricity that the system can store.

1.Low-voltage, small-capacity BESS: Suitable for microgrids, community or building energy storage, etc.

2.Medium-voltage, large-capacity BESS: Suitable for power quality improvement, peak shaving, etc.

3.High-voltage, ultra-large-capacity BESS: Suitable for large-scale grid peak shaving and frequency regulation.

Advantages of BESS

1.Improved energy efficiency: Peak shaving and valley filling, reducing grid pressure, and increasing the utilization of renewable energy.

2.Enhanced grid stability: Provides backup power, improving grid flexibility and reliability.

3.Promoting energy transition: Supports the widespread application of renewable energy, reducing reliance on fossil fuels.
