Energy Internet 2021

The Energy Internet in 2021 represents a vision of a digitally integrated, decentralized, and decarbonized energy ecosystem, combining smart grid technologies, renewable integration, and advanced energy management.

Concept and Vision

The Energy Internet is envisioned as an open, innovation-driven energy ecosystem that mirrors the digital internet's transformative impact on information and services. It emphasizes digitalization, decentralization, and decarbonization:

• Digitalization ensures accurate, timely, and shareable data on energy demand, supply, efficiency, and trends, enabling continuous optimization of energy delivery and system performance.
• Decentralization allows energy assets to be distributed and integrated across the supply chain, similar to how computing power moved from centralized mainframes to distributed networks. This includes integrating renewable energy sources, storage systems, and smart devices into a cohesive network.
• Decarbonization focuses on reducing carbon emissions by leveraging greener, decentralized energy infrastructure to meet demand anywhere with minimal environmental impact . The Energy Internet aims to create a flexible, open energy supply chain where innovators can focus on specific value propositions without reinventing the entire system, much like the digital internet enabled innovation across software and hardware platforms .

Research and Development in 2021

In 2021, the IEEE International Conference on Energy Internet (ICEI 2021) and the IEEE 5th Conference on Energy Internet and Energy System Integration (EI2) highlighted key research areas:

• Advanced energy management using deep reinforcement learning to optimize distributed energy resources and storage systems .
• Integration of large-scale renewable energy, including offshore wind farms, into onshore grids while addressing challenges like reduced grid inertia and frequency control .
• HVDC and AC/DC hybrid transmission systems, focusing on operational uncertainties, fault management, and system stability .
• Power quality and inverter harmonics, addressing resonance issues in distributed grid-connected systems . These conferences provided a platform for researchers and industry experts to share innovations in smart grid technologies, energy system integration, and predictive control strategies, all central to realizing the Energy Internet.

Industry Perspective

Industry leaders view the Energy Internet as a transformative opportunity to integrate the entire energy supply chain. By adopting an open, interoperable approach, companies can respond to volatile market conditions, optimize resource allocation, and accelerate the adoption of renewable and distributed energy technologies . The concept encourages collaboration across utilities, technology providers, and regulators to create a resilient, efficient, and low-carbon energy network.

Summary

In 2021, the Energy Internet was defined by its focus on:

• Digitalization: leveraging data for smarter energy management.
• Decentralization: distributing energy generation and storage across the network.
• Decarbonization: reducing emissions through renewable integration and efficient energy use.
• Research and innovation: advancing predictive control, grid integration, and system stability through IEEE conferences and academic studies . Overall, the Energy Internet represents a paradigm shift toward a flexible, intelligent, and sustainable energy ecosystem, analogous to the transformative impact of the digital internet on information and services.
