The term Ubiquitous Power Internet of Things first appeared in the State Grid Corporation of China's two sessions report, and became a key task on par with the strong smart grid. In the 2019 NPC and CPPCC report, the State Grid Corporation of China pointed out that the important material basis for building a world-class energy Internet enterprise is to build and operate the "two networks". networking". So what is the relationship between ubiquitous power Internet of Things and strong smart grid?
1. The basic connotation of ubiquitous power Internet of things
The Internet of Things was first proposed by Professor Kevin Ashton of the Massachusetts Institute of Technology. Its concept and connotation continue to evolve and develop. The current generally accepted definition is: information based on the Internet, radio and television networks, and traditional telecommunication networks. The carrier, the network that allows all ordinary physical objects that can be independently addressed to realize interconnection is called the Internet of Things. Its core technology system includes equipment encoding technology, equipment identification technology, communication technology, sensing technology, encryption analysis technology, etc. . With the introduction of the Internet of Things technology into the power grid field, the concept and application of the Internet of Things in the power industry continue to emerge.
In 2010, my country has already started research on the basic theory and application technology of the power Internet of Things. The power Internet of Things is the application of the Internet of Things in the smart grid. It is mainly divided into the perception layer, the network (transmission) layer, and the platform (data) layer. And application layer four-tier architecture.
The "Ubiquitous Power Internet of Things" proposed by the State Grid Corporation of China is an evolutionary development form of the Power Internet of Things. Its basic structure is consistent with that of the Power Internet of Things. Advanced communication technology realizes the interconnection of all things in the power system, human-computer interaction, and a smart service system with comprehensive status perception, efficient information processing, and convenient and flexible applications. Among them, the terminal sensing nodes of the sensing layer are larger in scale and collect more comprehensive data, covering all links, equipment and even components of the power system; the transmission layer will use new technologies such as 5G, Achieve higher data transmission efficiency; the data layer will collect and manage all data in a unified manner, and data barriers will be broken; the application layer will cooperate with the construction of a smart service system to provide users with more intelligent and humanized power universal services, and the value of data can be realized. reflect.
2. The relationship between "Strong Smart Grid", "Ubiquitous Power Internet of Things" and "Energy Internet"
The Energy Internet is a new form of energy industry development in which the Internet is deeply integrated with energy production, transmission, storage, consumption and the energy market. Its goal is to build a multi-type energy network and transportation network with the power system as the core and link. Integration, energy-information-economic ternary driven energy supply ecosystem, so as to realize the intelligent self-consistent, equal and open, green, low-carbon, safe, efficient and sustainable development of the energy ecosystem.
The Strong Smart Grid and the Ubiquitous Power Internet of Things are the specific implementation forms of the Energy Internet in the power system. The Strong Smart Grid is the "skeletal muscle" that supports the safe and stable transmission of the "energy flow" of the power system. The Ubiquitous Power Internet of Things is the "neural network". ", to realize the terminal collection and collection processing of the "information flow" in each link of the power system "source-network-load-storage".
