Smart grid concept
American definition: American energy Department of "Grid 2030":
a fully automated power transmission The network can monitor and control each user and grid node, and ensure the two-way flow of information and electric energy between all nodes in the entire transmission and distribution process from the power plant to the end user.
China’s definition: National 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 and coordinated development of power grids of various voltage levels. It combines modern advanced sensing and measurement technology, communication technology, information technology, computer technology and control technology with physical power grids. A new power grid formed by a high degree of integration. It aims at fully satisfying users’ power needs and optimizing resource allocation, ensuring the safety, reliability and economy of power supply, meeting environmental protection constraints, ensuring power quality, and adapting to the development of power markets, and achieves reliability and economy for users. , Clean, interactive Electricity supply and value-added services.
