In March 2019, the State Grid issued the construction outline of ubiquitous power Internet of things. Based on the analysis of the form and demand faced by the State Grid at present, the strategic goal of "three types and two networks" was defined, and the planning goal of preliminary completion in 21 years and completion of ubiquitous power Internet of things in 24 years was put forward.

Ubiquitous power Internet of things (IOT) is an intelligent service system that fully applies modern information technology and advanced communication technology such as mobile Internet and artificial intelligence around all aspects of the power system, realizes the interconnection of everything in all aspects of the power system, human-computer interaction, and has the characteristics of comprehensive state perception, information processing, convenient and flexible application.

Under the background of the continuous promotion of the current power system reform, the commercialization of power and the marketization of power trading have become clear, which will bring about the rediscovery of multiple value attributes of power, such as the clean attribute of power and the spatiotemporal attribute of power, which will give birth to a huge emerging business market space. In 2018, the power consumption of the whole society in China is 6.84 trillion yuan, and the above-mentioned ecosystem constructed by the power Internet of things is expected to breed a trillion level market space every year.

Intelligent electricity meter is an important part of intelligent power consumption, which is the "terminal nerve" to realize two-way interactive intelligent power consumption. It supports two-way metering, automatic collection, step tariff, time-sharing tariff, freezing, control, monitoring and other functions. In addition, smart meters can also provide users with many power consumption services, including distributed power metering, interactive services, smart home, smart community, etc. China's electricity meter industry has experienced the stage of mechanical electricity meter, ordinary electronic electricity meter, prepaid electricity meter and now basically universal intelligent electricity meter.

The next generation of smart meters will carry more functions than the traditional metering business. It can realize the business within the system (operation and maintenance support, metering, orderly power management) and ubiquitous business (global electrical fire protection, new energy access, energy efficiency management, water and gas data collection, room anti-theft, energy storage management, other applications, etc.). The application of Internet of things technology in the next generation of smart meters is one of the key smart terminal products in the construction of "two networks", which plays an important supporting role in the realization of informatization, automation and intelligence of power grid. With the promotion and implementation of the "ubiquitous power Internet of things" construction and the promotion of the demand for energy meter stock replacement, the next generation of smart meters will have broad market space.
