Introduction This paper aims to clarify the concepts and thinking of smart grid. Smart grid is the core platform of the new energy system. It is important for the adjustment of energy structure to develop smart grid .
Method This paper used the literature review method to sort out the concepts of microgrid, ubiquitous energy network and energy internet and its relationship with smart grid. Combined with China's energy development status and strategic needs, this paper discussed the construction ideas and key points of China's smart grid.
Result Smart grid is the deep integration of traditional power system and modern information technology, and energy Internet is the deep integration of smart grid and Internet thinking mode and technology. Smart grid is the basic platform of energy Internet. Microgrid, ubiquitous energy grid, smart grid and energy internet all aim to achieve cleaner, efficient and flexible energy use.
Conclusion Our data suggests that intelligent control on the high voltage side and intelligent built on distribution network should be emphasized and we should encourage the development of ubiquitous energy Internet which focus on the multiple energy sources complement.
