从智能电网到能源互联网：基本概念与研究框架

摘要

The traditional way of economic and social development,characterized by centralized utilization of fossil fuel energy, is gradually changing.On the other hand,the third industrial revolution is now rising.As the core technology of the third industrial revolution, the Energy Internet aims at facilitating large-scale utilization and sharing of renewable energy by integrating renewable energy and internet technologies.It will enhance the merging of electricity,transportation and natural gas networks,change the way of energy utilization,and finally achieve the goal of promoting sustainable economic and social development.Given this background,an overview of the Energy Internet is first provided,and a basic research framework developed.A definition of the Energy Internet is then suggested,followed by its basic architecture and main components. Several main research challenges to the Energy Internet,such as the wide-area coordination and control of distributed devices, the integration of the power system with the transportation system and natural gas network,as well as the cyber physical modeling and security,are next discussed in more details.%以化石能源集中式利用为特征的传统经济和社会发展模式正在逐步发生变革，而以新能源技术和互联网技术为代表的第三次工业革命正在兴起。作为第三次工业革命的核心技术，能源互联网力图结合可再生能源技术与互联网技术，推动分布式可再生能源的大规模利用与分享，促进电力、交通、天然气等多种复杂网络系统的相互融合，最终实现改变能源利用模式，推动经济与社会可持续发展的目的。在此背景下，展望了能源互联网的发展前景，并试图建立其基本的研究框架。首先，给出了能源互联网的初步定义，并概述了能源互联网的基本架构及其组成。随后，针对广域内分布式设备的协调与控制、电力系统与交通系统的融合、电力系统与天然气网络的融合、信息物理建模及安全等几个核心问题，探讨了能源互联网研究中可能面临的主要挑战。
