Energy Internet Platform Construction Plan

The Energy Internet Construction Plan involves integrating multi-energy systems with advanced ICT, hierarchical control, and distributed renewable energy to achieve efficient, low-carbon, and reliable energy networks.

Overview of the Energy Internet

The Energy Internet is a concept that combines energy systems with information and communication technologies (ICT) to manage energy resources efficiently, similar to how the Internet manages data. It enables packetized energy management, where energy is divided into discrete units for precise distribution and consumption, ensuring supply-demand balance and flexibility in energy usage ( ). The system integrates renewable energy sources, energy storage, and controllable loads such as electric vehicles and smart appliances.

Architecture and Layers

The construction of an Energy Internet typically involves a three-layer architecture ( ):

1. Physical Network Layer: Multi-energy interconnection networks, including electricity, heat, gas, and transportation energy systems, with distributed renewable energy sources like solar and wind. This layer ensures structural flexibility and energy sharing.
2. Support Layer (Energy Information Fusion): High-speed, high-bandwidth communication networks that collect, process, and transmit energy data across urban or regional systems, enabling intelligent energy management.
3. Service Layer (Energy Operation and Management): Platforms for energy service management, coordinating horizontal interactions between different energy systems and vertical interactions between providers and users.

Planning and Scenario Design

Energy Internet construction requires scenario-based planning, particularly under new-type urbanization ( ). This involves:

• Allocating physical elements across energy supply, conversion, transmission, and storage.
• Establishing 1+N scenario construction methods to adapt to diverse urban and regional energy demands.
• Ensuring interconnection, efficiency, low-carbon operation, digitization, and diversification in energy systems.

Key Technologies

The Energy Internet relies on several critical technologies ( ):

• Energy Routers: Devices that route energy packets similarly to data packets in the Internet.
• Distributed Renewable Generation: Wind, solar, biomass, and other clean energy sources.
• Energy Storage Systems: Batteries and other storage technologies to balance supply and demand.
• ICT and Machine-Type Communications: Enable ultra-reliable, low-latency, and massive connectivity for energy management.
• Hierarchical Control and Regional Coordination: Transform traditional tree-like power networks into hierarchical, autonomous, and interconnected networks for reliability and flexibility.

Implementation Strategy

The construction plan emphasizes:

• Integration of multiple energy forms and conversion technologies to optimize distribution.
• Active load management, including energy storage and electric vehicles, to handle temporal and spatial variability.
• Regional and global scaling, from home energy LANs to urban, regional, and global Energy Internet networks.
• Pilot projects and experimental deployments, as demonstrated in Germany, Switzerland, the US, and Japan, to validate technologies and operational models ( ).

Benefits

• Enhanced energy efficiency and utilization of renewable resources.
• Improved reliability and resilience of energy systems.
• Support for low-carbon and sustainable development.
• Flexibility in energy supply and demand management through packetized energy and hierarchical control. The Energy Internet Construction Plan represents a holistic approach to modern energy systems, combining technological innovation, urban planning, and renewable energy integration to create a sustainable, intelligent, and resilient energy network.
