The Energy Internet is structured as a multi-layered, distributed network integrating energy, information, and communication technologies to enable bidirectional energy flow and decentralized management.

Layered Architecture

The Energy Internet is commonly described using a six-layer model:

1. Business Layer – Defines market roles, business models, and energy trading mechanisms, including prosumers, contractors, and balance-responsible entities that manage energy transactions and settlements .
2. Use Case Layer – Represents specific applications and scenarios, such as peer-to-peer energy trading, microgrid operations, and virtual power plants .
3. Operation Layer – Handles real-time energy management, including supply-demand balancing, reactive power control, and frequency regulation .
4. Communication Layer – Provides the ICT infrastructure for data exchange, enabling secure, real-time communication between devices, energy routers, and system operators .
5. Interface Layer – Acts as a bridge between physical devices and higher layers, ensuring interoperability and standardized data exchange .
6. Appliance Layer – Comprises end-user devices, distributed energy resources (DERs), storage systems, and electric vehicles, which interact with the network through the interface layer .

Network Structure

The Energy Internet mirrors the Internet's hierarchical structure:

• Energy LANs – Local clusters of energy resources enabling microgrid operations and peer-to-peer energy trading .
• Energy WANs – Wide-area networks connecting multiple Energy LANs, analogous to the Internet backbone, often including transmission grids and sometimes multi-energy systems like natural gas networks .
• Energy Routers (ERs) – Devices that manage energy flow between LANs and WANs, similar to communication routers, ensuring efficient routing of energy packets .
• Energy Internet Service Providers (ISPs) – Evolved system operators that dispatch centralized resources, provide reliable energy services, and maintain network stability .

Key Features

• Bidirectional Energy Flow – Supports both consumption and generation at the prosumer level, enabling dynamic energy exchange .
• Integration of DERs – Incorporates renewable energy sources, storage systems, and electric vehicles for flexible energy management .
• Data-Driven Operations – Uses standardized data structures like Blocks of Energy Exchange (BEE) and Energy Internet Cards to track energy transactions and update user profiles automatically .
• Emerging Technologies – Blockchain, smart contracts, and IoT enhance transparency, security, and decentralized control .

Summary

The Energy Internet transforms traditional centralized grids into a distributed, intelligent, and interactive network, combining energy delivery with real-time information exchange. Its architecture ensures scalability, reliability, and efficient integration of renewable energy, while enabling prosumers to actively participate in energy markets and supporting innovative operational mechanisms.
