Architecture and Key Technology of Intelligent Energy Service System Based on Industrial Internet

摘要

China's intelligent energy shows a good trend of diversified development. However, intelligent energy research is still in its infancy, and most projects are based on simulation software to study regional integrated energy management; the existing pilot applications focus on regional integrated energy management, and there is a relative lack of research on the comprehensive control of power grid energy-using device. In view of the above problems, an intelligent energy service system based on industrial Internet design concept is proposed. First, carry out research on key technologies of intelligent energy service system, and build an intelligent energy service system architecture based on “Internet + ubiquitous Internet of things”, It adopts the architecture design of terminal layer, network communication layer, platform layer and business application layer, and elaborates the design idea and composition of each layer architecture. The technical architecture, physical architecture and security architecture of the system are also described. Among them, technical architecture is divided into display layer, service layer, storage layer, collection layer and protocol layer, summarizing the key technologies used in each layer of architecture. The physical architecture adopts the internal and external network structure, which not only realizes information isolation but also meets the needs of information interaction and business expansion. The security architecture focuses on boundary security, application security, data security, password security, network security, terminal security and other aspects of design, through isolation device, wireless virtual private network, digital certificate and other means to achieve isolation protection and secure communication. Finally, the application of the system is introduced. The system has been deployed in the headquarters of State Grid, mainly covering business modules such as intelligent energy data access, asset management, operation monitoring and operation management. Comprehensively supervise the operation and operation of client side energy equipment, and interconnect with marketing business, intelligent vehicle networking platform and other systems, realizing data and resource sharing, and building an unified, open and integrated industrial Internet service platform. Build orderly charging, optical storage and charging business applications on the basis of the platform; adopt “peak load shaving” strategy to reduce the peak load of the power grid and the user electricity cost, achieving mutual benefit and win-win results between enterprises and customers. The system has made innovations in the real-time concurrent processing of massive data intelligent energy “cloud platform + micro-service” system architecture, the orderly charging strategy and scheduling algorithm of electric vehicles, and the collaborative optimization of large-scale source network storage equipment, which can improve the consumption level of renewable energy and the overall utilization efficiency of social resources, and can provide a better guarantee for the safe operation of the power grid. At the same time, the system supports the distribution and deployment of provinces and cities, and the pilot projects in Beijing, Shanghai, Jiangsu and other places have achieved good results, verifying the practicability and effectiveness of the system.
