Energy Internet is a kind of new type information-energy fusion "Wan" which is constructed with Internet concept, based on open structure, trend hierarchical classification.User Side Internet of Energy, namely energy local area network, that is to establish the cooling heating power supply mode mainly on smart grid on the user side, use the renewable energy efficiently, realize the transformation and share of various forms of energy, improve energy comprehensive utilization efficiency, realize the cold thermal power and other energy joint optimized operation and energy echelon use, promote energy production, consumption, technology and system revolution of the demand side.In this paper, around the user energy Internet, the research status at home and abroad was summarized, the definition and characteristics was given, key technology was analyzed.In addition, basic structure of the user side energy Internet was promoted, energy router and energy information interaction mechanism was discussed, which provided new way of thinking for promoting the application of energy Internet in low carbon urban, intelligent park / cell, etc. IntroductionA Large scale use of fossil energy has resulted in increasingly serious climate change and other environmental crisis.The economic development models that seriously depend on traditional energy are difficult to continue and it is widely agreed to actively look for ways to use the new energy.The rapid development of renewable energy and information communication technology has created favorable conditions for the development of the energy Internet.Jeremy Rifkin, a famous American scholar, put forward the vision of energy Internet in his new book The Third Industrial Revolution.Energy Internet is a new type of energy utilization system, which is based on the new energy technology and combines advanced information technology, and its typical features mainly include: (1) high proportion of renewable energy; (2) allowing to connect a large number of distributed generation and energy storage devices; (3) wide area sharing of energy; (4) traffic electrification.As the combination of the energy field and information field, energy Internet has received extensive attention in the concept of the third industrial revolution and hs been regarded as the core technology in the field of future energy.The United States, Germany, Japan and so on, have begun a study of the energy Internet.The National Science Foundation of the United States studied the new power grid structure in 2008.Based on the renewable energy power generation and distributed energy storage device, this structure of power network realized cleanness and flexibility of the power grid.The Future Renewable Electric Energy Delivery and Management (FREEDM) system can build energy internet by realizing distributed system control with power electronic technology.Germany also put forward the idea of E-Energy in the same year.In 2011, Japan launched the Mark one energy router to achieve the cooperation of the energy interconnection local area network.Domestic research started late, so the existing related research is still in the stage of theoretical research.In 2013, State Grid formally put the concept of energy Internet to a strategic height and emphasized it in the smart grid and the third industrial revolution.In 2014, National Energy
