With the explosive growth of various devices, terminals and services, communication networks are in urgent need of security, reliability, flexible access and real-time interaction. Meanwhile, the power communication network extends to the low-voltage side, which needs to analyze a lot of interactive information to realize the perception, prediction and control of the system operation state. The traditional network model has certain deficiencies in taking into account the economy, efficiency and performance. This paper studies and analyzes the application of FlexE (Flexible Ethernet) technology in new type power systems to adapt to services with different granularities and performance requirements, realize unified access of various services, and promote the deep integration and adaptation of FlexE technology to the new type of power system.
