U.S. Department of Energy "Grid 2030": A fully automated power transmission network capable of monitoring and controlling each user and grid node, ensuring the bidirectional flow of information and power between all nodes in the entire transmission and distribution process from the power plant to the end user .

China Internet of Things School-Enterprise Alliance: The smart grid consists of many parts, which can be divided into: smart substations, smart distribution networks, smart energy meters, smart interactive terminals, smart dispatching, smart home appliances, smart electricity buildings, and smart city grids , intelligent power generation system, new energy storage system. Now a brief introduction to some of them. European Technology Forum: An electricity transmission network that integrates all actions of users connected to the grid to efficiently provide continuous, economical and safe electricity.

State Grid China Electric Power Research Institute: Based on the physical grid (China's smart grid is based on a strong grid with UHV grid as the backbone grid and coordinated development of power grids of various voltage levels), modern advanced sensing and measurement technology , communication technology, information technology, computer technology and control technology are highly integrated with the physical grid and form a new power grid. It aims to fully meet users' demand for electricity, optimize resource allocation, ensure the safety, reliability and economy of power supply, meet environmental constraints, ensure power quality, and adapt to the development of electricity marketization. , clean, interactive power supply and value-added services.
