In the wave of global energy transformation, energy storage, as a key supporting technology to address the intermittency and volatility of new energy and enhance the flexibility of power systems, is ushering in unprecedented development opportunities. According to data disclosed by the National Energy Administration, by the end of 2024, the cumulative installed capacity of new energy storage projects in China will exceed 70 GW, an increase of over 130% compared to the end of 2023. China's new energy storage industry is experiencing rapid growth.

Wintop, leveraging its 21 years of deep accumulation in the network communication field, has successfully assisted a large domestic energy storage project— a 300MW/1.2GWh energy storage power station in Hebei, achieving full capacity grid connection. As a key communication guarantee device in the project, Wintop's industrial switches, with their high reliability, low latency, and strong environmental adaptability, ensure real-time data transmission and precise control within the energy storage system, providing solid support for the efficient operation of the project.

The 300MW/1.2GWh energy storage power station project covers a construction area of 120 acres, with a total investment of 3.05 billion yuan. It is one of the first batch of independent energy storage demonstration projects on the grid side in Hebei province and also a key construction project in Hebei. Moreover, it is one of the largest independently operated energy storage power station projects connected to the grid in the country, showcasing China's technological strength and scale advantages in the field of new energy storage.

The project has configured 240 advanced lithium iron phosphate battery storage units to construct an energy storage matrix characterized by high safety, long cycle life, and excellent energy density, which can effectively smooth fluctuations in new energy generation and significantly enhance the flexibility and reliability of grid operations. This project provides strong support for regional power allocation and the absorption of new energy, further consolidating Zhangjiakou's leading position as a national renewable energy demonstration zone.

In the 300MW/1.2GWh energy storage power station project, industrial switches face various challenges while also requiring corresponding functional characteristics to meet project demands.

(1) Environmental Adaptability Challenges

Extreme Climate Endurance: The climate in the Chabei area is variable, with severe cold in winter and potential harsh weather such as high temperatures and sandstorms in summer. Industrial switches must have a wide operating temperature range and dust/water resistance design to ensure stable operation in extreme environments.

Electromagnetic Interference Protection: With dense electrical equipment within the energy storage station and a complex electromagnetic environment, industrial switches must possess strong anti-interference capabilities to prevent electromagnetic interference from affecting data transmission stability.

(2) Communication Stability and Real-Time Challenges

High Reliability Data Transmission: The energy storage system has a very high requirement for real-time data collection, monitoring, and control, so industrial switches need to ensure zero packet loss and low latency in data transmission to support real-time decision-making of the system.

Network Redundancy and Fault Tolerance: To avoid system paralysis due to single points of failure, industrial switches should support network redundancy designs, such as ring redundancy and link aggregation, to enhance network reliability.

(3) Security Challenges

Network Security Protection: As critical infrastructure of the grid, the energy storage system needs to guard against cyberattacks and data leaks. Industrial switches should integrate security features such as firewalls, VLAN isolation, and port security to ensure network security of the system.

Device Security: Industrial switches must have physical security characteristics to prevent physical damage and unauthorized access, protecting the devices from malicious destruction or illegal use.

(4) Scalability and Compatibility Challenges

System Expansion Needs: With the development of energy storage technology and the expansion of project scale, industrial switches need to support flexible network expansion, such as modular design and expandable ports, to accommodate future system upgrades.

Multi-Protocol Compatibility: The energy storage system may utilize various communication protocols and device manufacturers, so industrial switches need to support multi-protocol compatibility to achieve seamless integration between different devices.

The industrial switches used in the 300MW/1.2GWh energy storage power station must have high reliability, powerful data processing capabilities, comprehensive security protection, flexible network expansion and compatibility, as well as convenient management and maintenance features to adapt to extreme climates, ensure stable real-time data collection and monitoring, guarantee network security, support future system upgrades and multi-device integration, providing solid assurance for the efficient operation of the energy storage system.

In the 300MW/1.2GWh energy storage power station project, Wintop's industrial switches, with their excellent performance and reliability, provide comprehensive communication support for the station control layer, control network, and data network, ensuring the efficient and stable operation of the system.
