MW-level containerized battery energy storage system (CBESS) is an important support for the future development of power grids, which can effectively improve the stability, reliability and power quality of the power system. The research status of the MW-level containerized battery energy storage system is reviewed, the related concepts and working principles of the MW-level containerized battery energy storage system are introduced in detail, and the structure, design and application of the MW-level containerized battery energy storage system are comprehensively expounded. The characteristics and advantages of this paper are discussed in depth, and its development prospects and research directions are discussed in depth.

In recent years, MW-level battery energy storage technology has developed rapidly at home and abroad. Containerized battery energy storage systems have the advantages of high capacity, strong reliability, high flexibility, and strong environmental adaptability, and have broad application prospects in power grid systems. Compared with other energy storage batteries, the lithium battery energy storage system is relatively mature, and the upstream and downstream industrial chains are well-equipped, and there is a large space for cost reduction; at the same time, my country’s power system is in the peak period of power consumption, the power supply is tight, the utilization rate of transmission and distribution capacity is low, and there is no active power. shortage of power reserves and low transmission efficiency. The user side also puts forward higher requirements for the power quality of the load side. These problems have accelerated the rapid development of energy storage technology.

Energy storage technology has become one of the key technologies for the development and construction of smart grids, which can improve the low-energy quality of the grid and increase the utilization rate of renewable energy. With the rapid development of a new generation of lithium battery materials and the further improvement of battery technology, there is a wide range of applications for lithium batteries in energy storage. The containerized battery energy storage system has the advantages of mature technology, large capacity, mobility, high reliability, no pollution, low noise, strong adaptability, scalability, and easy installation, so the container energy storage system is used as the energy storage power source of the power system. , is the future development direction of energy storage.

Its main features are as follows:

(1) Modular design: ISO is the standard size, allowing easy ocean transportation and road transportation. They can be suspended from overhead cranes, boats, trucks and temporary sites.

(2) Rugged Design: ISO protects the cargo during transportation and will provide good protection from the weather, transportation and other environments during the lifetime of the energy storage system.

(3) Mobility design: Compared with other energy storage batteries, the advantages of lithium battery energy storage technology lie in mass and volume, strong mobility, and no geographical restrictions.

(4) Flexible base design: The container is easily applicable to any desired choice. This includes access to equipment such as air conditioners, photovoltaics, fans, access doors, power cable access and others.

It can also be configured with new energy access for energy storage and power supply.

(3) Microgrid

When the microgrid operates in an isolated network, the randomness of distributed energy resources and user loads is very large, and it is difficult to ensure the real-time balance of power generation and consumption, resulting in a wide range of frequency fluctuations and severe voltage fluctuations. The large-capacity and high-efficiency battery energy storage technology can suppress the interference of external power grids, ensure the power quality of local users, and further realize the smooth operation of the microgrid.

(4) Power quality

The MW-scale containerized battery energy storage system can be permanently connected to the grid, thereby providing the utility of fast-response frequency regulation of the grid.

(a) Renewable smoothing: Can be used for wind farms and large solar photovoltaic arrays to connect smooth output of these renewable energy systems.

(b) Remote Military Operations: May be used for remote military operations without access to the utility grid to provide electricity. MW-scale containerized battery energy storage systems can provide power for lighting, communications, and various military electronic hardware. Mobility can also improve the flexibility of use and expand new market business models, such as short-term leasing, temporary capacity expansion, and electricity consumption in construction projects, which has a relatively large room for development.

(c) Others: Large-capacity battery energy storage technology can also be used to improve the power quality of the distribution network. Provide dynamic reactive power compensation through converters, improve system voltage stability, and deal with voltage sag problems; provide backup, peak regulation, power system stabilizers, etc. for the system.
