The current assets and resources of the State Grid and the South Grid are very large, and the types and volumes of data generated are very large, and the value mining of data is still in the primary stage of big data applications. In the face of changes in energy forms, the integration of primary facilities and digital technology is not sufficient, as reflected in the relatively single function of secondary equipment, insufficient integration with new ICT technologies, and insufficient integration between new technologies and power services. To solve these fundamental problems faced by the current power grid, an integrated system of data collection, prediction, control, dispatch, and application built around data-driven is required. Among them, the power big data platform is the core of driving the operation of power data. Through the processing of big data, it drives the coordination of source, network, load and storage, the planning of primary and secondary facilities, the intelligent connection of data and applications, and the commercial operation of data.
By being compatible with different communication protocols, the edge IoT gateway shields the underlying business data differences, realizes the collection and local processing of marketing and power distribution data, and can communicate with the upper-level IoT platform, scheduling platform, and marketing platform. It can use the micro-service architecture, carry AI intelligent analysis, and realize various business innovations through the data orchestration and APP application of the central cloud. The edge IoT gateway will become the basic-level comprehensive data processing node of the source network load storage in the future, which is very important.
A strong capillary network for power data: In the past, the power backbone communication network mainly carried control data, but now it may carry AR/VR data. It is necessary to consider the integration of real-time and non-real-time services. The future power backbone communication network will develop towards higher speed, larger bandwidth, longer transmission distance, and more intelligence. At the same time, the network layer needs to be flattened and meet the high reliability requirements of intelligent regulation and converged bearer of power services.
5G applications bring innovative leaps to power data applications: the coordination of source, network and load storage involves the management and control of the whole process and the whole domain. The data collected by the current power grid mainly serves the global dispatching and situation awareness of higher voltage levels, and lacks real-time and global awareness. consideration of the problem. The power network needs to increase the edge layer, and the edge layer can solve the communication coordination, computing power coordination and application coordination between the cloud and the edge. Only after these several are dealt with together can the real-time and global business be truly realized in the whole process and the whole domain, and finally the digital twin can be realized. At present, FiberHome and China Electric Power Research Institute jointly undertake the national project of the source-network-load-storage wide-area control system. In the project, FiberHome mainly undertakes the construction of the edge computing platform.
The core of digital drive: artificial intelligence is the realization and upgrading of power data value. Fiberhome, State Grid and China Southern Power Grid have jointly carried out AI application scenario verification under typical power business scenarios, mainly including grid ecological perception and AI-assisted power dispatching services. The combination of intelligence, AI and VR technology realizes automatic inspection and fault determination, etc., and has been applied in some businesses in the Central China Power Grid.
Multi-level processing of data: The traditional security guarantee of power data can be achieved by building a strong gatekeeper and providing a good encryption method, but the fundamental security guarantee should be continuous localization. In the field of data security, Fiberhome has chosen two strategies. One is to use the server computing base independently built by China Information Technology Group under the Yangtze River Computing to build its own service base, and at the same time, it uses the cloud operating system developed by its own technology as the operating platform. On the other hand, for databases, middleware, and storage, we hope to work with the industry to build a localized ecosystem.
The above is the overall consideration of FiberHome for all aspects of power data. In fact, it builds the support capability for the entire digital transformation of power according to digital topics. At present, FiberHome has done corresponding work at all levels of power data end-to-end support capability. There are already good practices in some fields, some fields are cooperating with power peers, and some fields have clear road signs, such as smart terminals, 5G construction, power communication networks, centralized and edge data centers, big data + artificial intelligence and more. Fiberhome has the confidence to embrace the era of energy internet together with electricity.
