Energy Internet System Architecture and Requirements

The Energy Internet integrates distributed energy resources with advanced ICT to enable intelligent, scalable, and secure energy management through a networked architecture of energy routers, prosumers, and virtual power plants.

System Architecture

The Energy Internet is designed as a hierarchical and distributed network that combines energy flow with information flow, similar to the Internet model. Its architecture typically includes:

  • Backbone Network: Large-scale power grids that form the main transmission layer.
  • Local Area Networks (Microgrids): Smaller, localized grids that integrate distributed energy resources (DERs) such as solar panels, wind turbines, and energy storage systems.
  • Energy Routers (ERs): Analogous to communication routers, ERs manage the routing of energy flows between different network nodes, enabling bidirectional energy exchange and efficient load balancing .
  • Prosumers and Virtual Power Plants (VPPs): Consumers who also produce energy (prosumers) are aggregated into VPPs to optimize energy generation, storage, and consumption .
  • ICT Integration: Cloud computing, fog computing, IoT, and big data analytics are embedded to monitor, control, and optimize energy distribution and consumption in real time .

Functional Requirements

To operate effectively, the Energy Internet must meet several key requirements:

  • Cross-disciplinary Support: The system must integrate multiple energy types (electricity, gas, thermal energy) and support diverse equipment, including generation, storage, transmission, and metering devices .
  • Scalability and Flexibility: The architecture should allow dynamic expansion, user-defined modeling, and scenario simulation to accommodate evolving energy demands and new technologies .
  • Standardization and Interoperability: Equipment and communication protocols must adhere to standardized models to ensure seamless information exchange and system integration across multi-energy networks .
  • Reliability and Security: The system must guarantee stable energy supply, protect against cyber threats, and maintain quality of service across all network layers .
  • Experimental Platform Support: For research and development, the Energy Internet requires platforms capable of multi-user access, repeated simulation, and testing of algorithms, market models, and energy management strategies .

Technological Components

Key technologies enabling the Energy Internet include:

  • Smart Power Electronics: For efficient energy conversion and distribution.
  • Advanced Sensing and Metering: To monitor energy flows and system performance.
  • Communication Networks: High-speed, reliable networks for real-time data exchange.
  • Control Algorithms: Hierarchical distributed control systems for energy routing, load balancing, and market operations .

Summary

The Energy Internet represents a paradigm shift from centralized power systems to a fully connected, intelligent, and distributed energy network. Its architecture integrates DERs, energy routers, prosumers, and ICT technologies to achieve efficient, reliable, and secure energy management. Meeting its functional requirements involves ensuring interoperability, scalability, cross-disciplinary support, and robust experimental platforms for continuous innovation and optimization .
