FAQS about New energy battery cabinet arrangement

How to design an energy storage cabinet?

The following are several key design points: Modular design: The design of the energy storage cabinet should adopt a modular structure to facilitate expansion, maintenance and replacement. Battery modules, inverters, protection devices, etc. can be designed and replaced independently.

What type of batteries are used in energy storage cabinets?

Lithium batteries have become the most commonly used battery type in modern energy storage cabinets due to their high energy density, long life, low self-discharge rate and fast charge and discharge speed.

What is energy storage cabinet?

Energy Storage Cabinet is a vital part of modern energy management system, especially when storing and dispatching energy between renewable energy (such as solar energy and wind energy) and power grid.

Why do energy storage cabinets use STS?

STS can complete power switching within milliseconds to ensure the continuity and reliability of power supply. In the design of energy storage cabinets, STS is usually used in the following scenarios: Power switching: When the power grid loses power or fails, quickly switch to the energy storage system to provide power.

Grid-side independent energy storage project

This project marks the first 220kV voltage level new energy storage power station in Foshan Power Grid, with a construction scale of 208MW/416MWh. 9 sets of Zhiguang Electric's independently developed and technically leading High-Voltage Cascade Direct-Mounted Energy Storage Systems will be deployed, configured with full liquid-cooling technology, and the whole energy storage power station adopts Zhiguang Electric's “5S” full-stack technology to realize the whole life cycle management, monitoring and control of the energy storage system.After the project is completed and put into operation, it will provide auxiliary services such as frequency regulation and peak shifting for the power grid, effectively enhance the power supply reliability of the Foshan regional power system, promote new energy consumption, and play an important role in promoting the development of Guangdong's new electric power system, and the project is expected to be completed and put into operation in June 2025.
