Once the concept of ubiquitous electric power Internet of Things was put forward, it became an Internet celebrity in the field of Internet of Things. State Grid Corporation of China put forward a new strategic goal of "three types and two networks" in the report of the two sessions in 2019 and on many occasions. Three types refer to " hub type, platform type, and sharing type", the two networks refer to "strong smart grid and ubiquitous power Internet of Things".
The ubiquitous power Internet of things, that is, around all aspects of the power system, fully applies modern information technologies and advanced communication technologies such as "big data, cloud computing, Internet of Things, mobile Internet, and artificial intelligence" to realize power system It is an intelligent service system characterized by the interconnection of all things and human-computer interaction in all links, comprehensive state awareness, efficient information processing, and convenient and flexible applications. Its architecture includes perception layer, network layer, platform layer, and application layer. In the future, one of the development goals of the ubiquitous power Internet of Things is to make the "Internet of Things" an infrastructure, ubiquitous electricity, and ubiquitous connections.
Perception layer: unify terminal standards, promote homogenous collection of cross-professional data, realize deep coverage of power distribution side and power consumption side collection and monitoring, and improve terminal intelligence and edge computing level
Network layer: Promote the construction of electric power wireless private network and terminal communication, enhance bandwidth, realize deep full coverage, and meet the needs of emerging business development
Platform layer: realize the unified management of ultra-large-scale terminals, deepen the construction of a unified data center for all services, promote the construction and application of the "State Grid Cloud" platform, and improve the efficient data processing and cloud-mist collaboration capabilities
Application layer: fully support the intelligent operation of core business, comprehensively serve the energy Internet ecology, and promote management improvement and business transformation
The role and characteristics of ubiquitous power Internet of things
1. The ubiquity of connection
◆Micropower wireless ad hoc network

◆Satisfies real-time business, agile processing, data optimization such as precision control and scheduling
3. Data sharing
◆Massive perception layer data gathers in the application layer and becomes an important data resource
◆The opening, sharing and sharing of data has become an urgent need and an inevitable trend
◆The standardization of data models breaks through the "chimney" barriers of various businesses
◆Achieve the horizontal penetration of different business logics
4. Platformization of services
◆The air-ground integrated network has become a "plug and play" network platform
◆Standardization of interfaces and protocols promotes the unification of access and connection
◆A combination of a general horizontal platform and a vertical specialized platform
◆The openness of the platform and the improvement of intelligent service level based on the platform
Application Scenarios of Ubiquitous Power Internet of Things
In the field of traditional power grids, the application scenarios of the ubiquitous power Internet of Things can be generally divided into two categories: control and collection.
Among them, the control category includes distributed power distribution automation, power load demand-side response, distributed energy regulation, etc.; the collection category mainly includes advanced metering, smart grid big video applications. In the future, in the ubiquitous power Internet of Things application scenario, the control field will switch from the current star centralized connection mode to point-to-point distributed connection, the master station system will gradually sink, and more local nearby control and edge computing will appear.
As for collection applications, under the ubiquitous power Internet of Things, there will be major changes in collection frequency, content, two-way interaction and other aspects.
In emerging fields, the Ubiquitous Power Internet of Things will empower power grid enterprises and emerging business entities in areas such as unified perception, physical ID application, precise and active emergency repair, virtual power plant, one-stop smart energy service, and big data application. Taking the integrated energy service platform as an example, for systems such as the energy efficiency service sharing platform, the provincial customer-side energy service platform, the new energy big data platform, the Internet of Vehicles, the photovoltaic cloud network, and the smart energy control system that can be applied to the portal, the large-scale agglomeration Externally, it can provide platform-based shared services such as grid connection, monitoring, measurement, billing, transaction, operation and maintenance for various emerging business entities.
