The main function of hệ thống lưu trữ năng lượng (ESS) plays a crucial role in the power system. The following is a detailed explanation of its main functions.

1、 Energy Storage System can Balance Power Supply and Demand  

Hệ thống lưu trữ năng lượng can effectively balance power supply and demand, especially in the context of the widespread application of renewable energy sources such as wind power and photovoltaics. Due to the intermittency and volatility of renewable energy generation, energy storage systems can charge and store excess electricity during periods of low demand; And discharge during peak electricity demand to supplement the power supply of the grid, thereby alleviating the power supply pressure of the grid and ensuring stable power supply.

2、 Energy Storage System can Improve Energy Utilization Efficiency   

Các hệ thống lưu trữ năng lượng significantly improves energy utilization efficiency by optimizing the storage and release of electrical energy. During periods of low electricity demand, energy storage systems utilize low-cost or idle electricity for charging, avoiding energy waste; During peak electricity demand, the hệ thống lưu trữ năng lượng releases electricity to meet the electricity demand during peak hours, reducing the need for power rationing or power outages due to power shortages, thereby improving overall energy utilization efficiency.

3、 Energy Storage System can Stabilize the Operation of the Power Grid 

As an important auxiliary equipment of the power grid, hệ thống lưu trữ năng lượng are of great significance for maintaining the stable operation of the power grid. It can quickly respond to frequency and voltage fluctuations in the power grid, provide necessary frequency regulation and voltage support services, and ensure the stable operation of the power grid. In addition, in the event of a power grid failure or outage, the hệ thống lưu trữ năng lượng  can also serve as a backup power source to provide continuous power support for critical equipment and prevent losses caused by power outages.

4、 Energy Storage System can Promote the Integration of Renewable Energy   

The combination of hệ thống lưu trữ năng lượng and renewable energy generation facilities greatly promotes the integration and utilization of renewable energy. Due to the intermittency and volatility of renewable energy generation, hệ thống lưu trữ năng lượng can effectively regulate and balance it, making renewable energy generation more stable and reliable. This not only improves the utilization rate of renewable energy, but also reduces the consumption of fossil fuels and environmental pollution, providing strong support for achieving a green and low-carbon energy structure.

Tóm lại, hệ thống lưu trữ năng lượng has the main functions of balancing power supply and demand, improving energy utilization efficiency, stabilizing grid operation, and promoting the integration of renewable energy in the power system. With the continuous advancement of technology and the expansion of applications, hệ thống lưu trữ năng lượng will play a more important role in the future energy field.
