At the renewable energy era, the Smart Grid (SG) & Smart Natural Gas Grid (SNG), as the core bone structure of Energy Internet (EI), will connect thousands of basic units—Distributed Energy Systems (DES), realizing high-efficient transformation and the balance between. At the renewable energy era, the Smart Grid (SG) & Smart Natural Gas Grid (SNG), as the core bone structure of Energy Internet (EI), will connect thousands of basic units—Distributed Energy Systems (DES), realizing high-efficient transformation and the balance between. First, this paper analyzes the topological features of “hierarchical control, intra-layer partition, interregional interconnection, and regional autonomy” of the Energy Internet. On this basis, the hierarchical ring network autonomy (HRNA) topological generation and evolution mechanism of the. In this paper, a hierarchical structure of grid energy router is proposed to greatly facilitate peer-to-peer energy sharing among energy routers. It can be placed at critical buses to make active distribution networks develop into multiple interconnected prosumer-based autonomous systems. Its features, such as plug-and-play mechanism, real-time bidirectional flow of energy, information, and money can lead to significant benefits and innovation in electricity production and. Energy Utilization System includes energy transformation & transportation subsystem via certain media; energy utilization subsystem, which includes three areas: industry, architecture & transportation. The three energy finally terminal use forms are: electricity, heat and movement driving force. At present, it is commonly believed that full exploitation and utilization of green energy and.
