Dyness Knowledge | The role of energy storage batteries in small and medium-sized C&l ESS

In small and medium-sized industrial and commercial energy storage systems, energy storage batteries are a key link and are widely used in energy storage, balancing grid loads, and improving system stability. With the continuous acceleration of clean energy utilization and the rapid development of energy storage technology, various types of energy storage batteries have been widely used in small and medium-sized industrial and commercial energy storage systems. This article will focus on several common energy storage batteries and their technical characteristics.

In industrial and commercial energy storage systems, energy storage batteries are an extremely important energy storage device with the following roles and functions.

Smoothing power fluctuations and filling peak and valley differences: Energy storage batteries can be charged during low-load periods and release stored energy during high-load periods to smooth power fluctuations in the grid and fill peak and valley differences, thereby improving power efficiency and reducing costs.

Respond to sudden load demands: Energy storage batteries can respond quickly and provide additional power output to respond to sudden load demands, ensure stable operation of the power grid, and avoid load imbalance and power outages.

Enhance power supply reliability and stability: As a backup power source, energy storage batteries can provide emergency power supply in the event of grid failure or power outage, ensuring the continuity and stability of production and facility operation of industrial and commercial enterprises.

Improve the utilization rate of clean energy: Energy storage batteries can be combined with renewable energy systems to store electricity from unstable renewable energy sources such as wind energy and solar energy, smooth out their volatility, and improve the utilization rate of renewable energy and the proportion of renewable energy connected to the grid.

Load regulation and frequency response: Energy storage batteries can be charged and discharged within millisecond response time, which can be used for frequency regulation, load balancing and grid frequency response, improving grid operation stability and power quality.

Energy saving, emission reduction and reduction of energy consumption: Energy storage batteries have the characteristics of high efficiency and low energy loss, which can improve energy utilization efficiency, reduce energy consumption and carbon emissions, and achieve energy saving, emission reduction and green development.

Intelligent management and optimized operation: The energy storage battery is equipped with an intelligent management system that can monitor, control and optimize the battery status in real time to maximize battery life and improve system efficiency.

The following are several common energy storage batteries and their characteristics in energy storage systems.

First of all, lithium-ion batteries, especially lithium iron phosphate batteries, are currently the most widely used energy storage batteries in small and medium-sized industrial and commercial energy storage systems. Lithium-ion batteries have the characteristics of high energy density, long life, high efficiency and low self-discharge rate, and are suitable for the daily energy storage needs of small and medium-sized industrial and commercial energy storage systems. With the continuous innovation of technology and the reduction of costs, the performance and reliability of lithium-ion batteries are constantly improving, and they have become the preferred battery type in small and medium-sized industrial and commercial energy storage systems.

Secondly, lead-acid batteries are a type of energy storage battery with lower cost but stable performance compared to lithium batteries. Lead-acid batteries have mature technology and wide applications, and are suitable for scenarios with high cost requirements and low cycle requirements in small and medium-sized industrial and commercial energy storage systems. Although the energy density and cycle life of lead-acid batteries are relatively low, their low price and good reliability still play an important role in some small and medium-sized industrial and commercial energy storage systems.

In addition, sodium-sulfur batteries are also a common type of energy storage battery. Sodium-sulfur batteries have the advantages of high energy density, long cycle life and good high-temperature working performance, and are suitable for energy storage needs that require high energy density and long cycle life. However, since its operating temperature is generally in a higher environment, 300-350℃, the battery requires a certain amount of heating and insulation when working, which has certain limitations for application scenarios.

In general, there are many types of energy storage batteries in small and medium-sized industrial and commercial energy storage systems, each with its own characteristics. It is necessary to select suitable energy storage batteries to match system requirements, performance, cost and other factors.
