A Review of Smart Grids and Their Future Challenges

With the development of science and technology and the increasing emphasis on renewableenergy, smart grids are being vigorously developed in many countries and regions including Europe, theUnited States and China. The smart grid is the main practice trend of efficient transmission of modernpower resources. It has the advantages of good power transmission, low resource loss and strong correlationof resources transmission. Therefore, it occupies an important position in large-scale utilization of powerresources. Thus, this paper, based on the theory of smart grid, discusses the research direction, practicalinnovation and application of smart grid, provides theoretical reference for the comprehensive utilization ofpower resources in China, and promotes the intelligent exploration of domestic electric resource application
