Design of energy internet based on information internet

Energy Internet (EI) has been proposed to be a main direction for future energy structure to solve the resources shortage and environmental pollution problems. Energy internet is a typical complex network in which power grid, gas grid and heat supply network are all coupled. Compared to the existing network, it is believed that information internet has the most similarities with the energy internet. In this paper, the research are attempting to build a reasonable and simple energy internet based on information internet. The construction of EI in different regions is discussed firstly. And then, inspired by the hierarchy of information internet structure, we also establish an EI hierarchy in 4 layers. Finally, in order to give a specific topology description, we focus on the transaction process in EI by using network science theory and give a detailed analysis of relevant parameters about the transaction in EI. By using the design idea of information internet, we focused on the problem that what EI will look like or should look like in the future.
