Increasing the proportion of clean energy, especially renewable energy in power consumption terminals, and achieving a comprehensive complementary configuration of multiple energy types is the future development trend of the energy Internet. The requirements of energy Internet for demand response have changed from the traditional way to multi-energy comprehensive demand response. Firstly, the development of the energy Internet at home and abroad is outlined, as well as the energy Internet promotion projects and policies. Then, the commonly used demand response technologies such as automatic demand response technology, energy storage technology, information and communication technology, power metering technology, intelligent control technology, and load aggregation technology are introduced and analyzed.The focus is on the development of automatic demand response technology, energy storage technology, and information and communication technology in the energy Internet environment.Among them, information physical systems and interface standards are the key to automatic demand response technology, and energy storage technology focuses on reducing costs, and ICT focuses on the application of new technologies such as blockchain and 5G. Finally, the future development direction of each demand response technology and the problems it faces are summarized, and suggestions are made to promote the development of multi-energy demand response technology.
