GB/T 35681-2017 in English

1. Background and Significance of Standard Formulation

As the proportion of renewable energy in the power grid increases, traditional power systems face load regulation pressure. Demand response technology has become an important means to improve the flexibility and efficiency of the power system by flexibly adjusting user-side loads and optimizing power grid operation.

2. System composition and participants

3. Comparative analysis of standard frameworks

Comparison between GB/T 35681-2017 and GB/T 32672-2016:

• Expanded functional requirements of demand response system
• The calculation method of implementation effect has been refined
• Safety protection measures have been enhanced
• The application of renewable energy consumption scenarios has been increased

4. Key technical points

4.1 Functional requirements of demand response service system

4.2 Functional requirements of demand response aggregation system

The demand response aggregation system is mainly responsible for coordinating the response behaviors of multiple users. Its core functions include:

• User management: registration, file creation and query
• Resource management: equipment registration, parameter maintenance and classification
• Project management: receiving and managing project information of the superior demand response service system, and supporting its own project design

4.3 Functional requirements of demand response terminals

As a key device on the user side, the demand response terminal needs to implement the following:

• Communication function: information interaction with the superior system and subordinate equipment
• Data collection: collecting user power load and equipment operation status information
• Command control: generating and issuing control commands according to event signals
• Value-added services: energy efficiency management, equipment status monitoring

5. Implementation suggestions

5.1 System design and deployment

Key points:

• Ensure that the system has good scalability and supports distributed storage and dynamic expansion
• Strengthen security protection measures and use encryption, signature and other technologies to protect key data
• Implement simulation and exercise functions to support business simulation and personnel training

5.2 Coordinated implementation with other standards

This standard is closely related to standards such as GB/T 32127 (demand response effect monitoring) and GB/T 32672 (general technical specifications). It is recommended to fully consider the connection and coordination between these standards in practical applications.

5.3 Performance Optimization

According to the standard requirements, the system should meet the following performance indicators:

• Information monitoring time interval: ≤15 minutes
• Data storage capacity: ≥1000 users, retention period ≥3 years
• Support large-scale user access and rapid processing of response events

6. Conclusion

GB/T 35681-2017 standard provides comprehensive technical specifications for the construction and operation of power demand response systems, which is of great significance to improving the flexibility of the power grid and promoting the consumption of renewable energy. It is recommended that relevant companies strictly follow the standard requirements for system design and deployment in actual applications to ensure the integrity of system functions and the reliability of performance.
