Energy Internet: State of the Art and Challenges

Abstract

The Energy Internet is expected to transform the landscape of electricity generation portfolio, distribution, and consumption through the integration of advanced sensing, communication, and control technologies in daily grid operations. This paper explores the profound impact of various smart grid concepts, such as dynamic pricing, distributed generation, and demand management, on information and communication technologies services within the Energy Internet. The synergy between smart grid principles and the Energy Internet has introduced a new dimension to efforts aimed at enhancing energy efficiency and reducing operational costs in communication networks and data centers. This survey provides a comprehensive overview of the Energy Internet Concept, strategies for achieving energy-efficient communications and data centers, and the dynamic interplay between the Energy Internet and information and communication infrastructures. While previous studies have individually examined the Energy Internet, energy-efficient communications, and green data centers, a critical need exists to systematically categorize and survey research at the intersection of these fields. To bridge this gap, our survey commences by elucidating the energy Internet concept and its architectural framework. Subsequently, an exploration of energy-routing devices and algorithms employed in prior studies is undertaken. Finally, the challenges encountered within the Energy Internet domain are explained. This comprehensive survey aims to offer a panoramic perspective on the Energy Internet, illustrating its conceptual intricacies and challenges, along with an exploration of how previous studies have endeavored to address them.
