DL/T 2937-2025 in English

Standard Background and Significance

DL/T 2937-2025, "Functional Requirements for Energy Exchange Devices in Energy Internet," is my country's first technical standard specifically for energy exchange devices in the energy internet. It was jointly drafted by 12 organizations, including State Grid Shanghai Energy Internet Research Institute Co., Ltd. The development of this standard marks a significant step forward in the standardization of key technologies and equipment for the energy internet in my country, providing technical support for building a clean, low-carbon, safe, and efficient modern energy system.

Core Concept Analysis

Energy exchange devices are defined as cyber-physical systems that aggregate and manage energy and energy-carrying media, such as electricity, cooling, heat, gas, fuel oil, and hydrogen, and possess energy conversion, transformation, and distribution capabilities, integrating energy. This concept transcends the limitations of traditional single energy systems and enables multi-energy complementarity and coordinated optimization. The core functional modules, the Electric Energy Exchange Unit and the Thermal Energy Exchange Unit, are responsible for the conversion and distribution of electrical and thermal energy, respectively, reflecting the diverse energy forms within the Energy Internet. The standard requires that input and output ports support plug-and-play functionality for multiple energy sources and working fluids, including electricity, gas, fuel oil, and hydrogen. This provides technical support for the flexible integration of distributed energy resources. The electric energy input port must have automatic synchronous grid connection and comply with the grid connection technical requirements of GB/T 33592 and GB/T 33593.

Standardized design of communication unit

The communication unit adopts a modular design. The physical interface supports standard interfaces such as RJ45, optical fiber and RS485. The communication protocol is compatible with the DL/T 860 series standards. It also supports wireless communication protocols such as WiFi, 4G, 5G, and NB-IoT to ensure device interoperability.

Overall functional architecture

Energy exchange function

The standard requires the device to be able to convert, transform, and distribute primary energy sources such as gas and fuel oil, and secondary energy sources such as electricity, cooling, heat, and hydrogen, achieving stable and reliable output of multiple energy sources. Energy supply quality control must comply with relevant standards such as GB/T 33833 and GB/T 19862.

Operation control system

Operation control functions include three levels: distributed energy control and management, load control and management, and operating mode switching. The device must have the function of smooth switching between multiple operating modes, and the transition from normal state to fault state should ensure the continuity of energy supply.

Intelligent energy management

Energy management functions cover energy metering, energy supply forecasting, energy demand forecasting and energy optimization scheduling. The device should be able to formulate the operation plan of each energy exchange unit through optimization calculation based on remote scheduling plans, forecast data and real-time operation data.

Market trading and carbon trading functions

For the first time, the standard incorporates market trading functions into the technical requirements of energy exchange devices, supporting real-time information exchange with various energy dispatch centers and trading markets. The carbon trading function requires that the device has the ability to calculate carbon emissions and carbon emission reductions, in compliance with DL/T 2126 Technical Guidelines for Carbon Emission Trading.

Compared to traditional energy equipment, the new generation of energy exchange devices emphasizes multi-energy complementarity, cyber-physical integration, and market interaction. The standard references over 40 relevant national and industry standards, establishing a comprehensive technical standard system and providing a clear technical roadmap for equipment manufacturers. Implementation Recommendations and Application Cases Design and Manufacturing Recommendations During the R&D process, it is recommended that equipment manufacturers focus on the following aspects: adopt universal interfaces and modular hardware and software designs to ensure good scalability; strengthen the information security functions of the communication unit to comply with safety standards such as GB/T 20270 and GB/T 22240; and optimize the coordinated control algorithm of the control unit to improve system operating efficiency. Operation and Maintenance Recommendations Operating units should establish a comprehensive equipment status monitoring system to regularly monitor and warn of the charge state and thermal storage status of energy storage units; formulate detailed load shedding strategies and operation mode switching plans; and strengthen data statistical analysis to provide decision support for energy efficiency improvement and energy-saving renovations. Typical Application Scenarios This standard is applicable to various energy internet application scenarios, such as industrial parks, commercial buildings, and residential communities. In industrial park applications, energy exchange devices can achieve the coordinated supply of multiple energy sources such as electricity, heat, and cooling, significantly improving the comprehensive energy utilization efficiency; in commercial buildings, energy costs can be minimized through optimized scheduling. Impact Analysis of Standard Implementation The implementation of DL/T 2937-2025 will have a profound impact on the development of the energy Internet industry: on the one hand, it will provide unified technical specifications for equipment manufacturers to promote the healthy development of the industry; on the other hand, it will provide a technical basis for users to select and use energy exchange devices, ensuring equipment quality and performance. With the advancement of the carbon peak and carbon neutrality goals, energy exchange devices that meet the requirements of this standard will play an important role in the construction of new power systems and energy Internet, and provide key technical support for achieving clean and low-carbon energy transformation.
