Research on Status and Prospects of Battery Energy Storage Stations on Energy Internet

The application of the fourth industrial revolution has become an opportunity and objective condition for realizing the energy Internet, in which energy storage technology is the cornerstone. However, the research on energy storage technology often stays in the aspects of power grid cutting and valley filling, improving power quality, etc., and the research on the working mechanism and control methods in the energy Internet and future development is still scarce. Starting from the current situation of battery energy storage in the energy Internet, this paper first introduces the differences of nature between the batteries and the characteristics of energy storage power stations at home and abroad. Then several key technologies of the battery energy storage system are explained. Finally, the technical bottleneck and development prospects of battery energy storage in the energy Internet environment are prospected.
