摘要
针对源网荷储用户侧底层大量物联终端产生的海量数据在云端(调度端)分析汇总和边缘端实时计算2个层面的需求,以及用户侧物联网终端交互过程的去中心化需求,文章提出一种基于边缘计算和区块链协同的源网荷储物联网架构以及边缘节点、区块链应用服务的配置方法。在该架构下,源网荷储系统的调度控制等功能、数据处理任务分别由临近物联网终端侧的边缘计算节点完成。考虑源网荷储系统对实时性、可扩展性和安全性的高要求,所以进一步引入区块链的逻辑视角,阐述了利用“边缘计算+区块链”的源网荷储关键技术,搭建了基于该技术的源网荷储架构。该架构可更好地反映需求侧实时信息,更有利于源网荷储的稳定调度,也提高了电力系统的数据安全性和存储安全性。
Aiming at the needs of analyzing and summarizing the massive data generated by a large number of the Internet of things(IoT)terminals on the user side of the source-grid-load-storage in the cloud side(scheduling side)and real-time calculation at the edge side,and the decentralized requirements of the userside interaction process,a source-grid-load-storage IoT architecture based on edge computing and blockchain collaboration,as well as edge node and blockchain application service configuration methods are presented.Under this architecture,the functions such as scheduling control and data processing of the source-grid-loadstorage system are completed by edge computing nodes near the terminal side of the IoT.Considering the high requirements of the source-grid-load-storage system for real-time,scalability and security,the logical perspective of the blockchain is further introduced,and the key technology of the source-grid-load-storage using"edge computing and blockchain"is described and a source-grid-load-storage architecture based on this technology is built.The architecture can better reflect the real-time information on the demand side,which is more conducive to the stable scheduling of source-grid-load-storage,and also improves the data security and storage security of the power system.
