A Practicable Design of Energy Internet Compatible with Current Power Supply System

Abstract

Energy Internet, a new energy system combined with advanced energy and information technology, is considered to be an effective method to solve distributed energy consumption problem. Power system is the most suitable natural carrier for the construction of Energy Internet, but the physical laws between electric power flow and information flow are different. The concept of Internet cannot be applied mechanically to Energy Internet. This article proposed a method for designing energy interconnection system which can compatible with the existing power grid structure satisfactorily and achieve the function of plug-and-play for power generation, consumption and storage equipment. Meanwhile, this article discussed the role of Micro Grid (MG) in the construction of Energy Internet and pointed out the interaction relationship between MG and Energy Internet. The ideas put forward in the article can be conducive to the construction of Energy Internet and promote the effective utilization of distributed energy.
