能源互联网概念与特征辨识研究

能源互联网受到了广泛关注，目前对其概念及特征有多种理解及认知，为了辨析能源互联网的概念、辨识能源互联网的特征，有效推进能源互联网发展，对能源互联网的发展历程进行了调研及梳理，提出到目前为止能源互联网大致经过3个发展阶段：概念孕育及提出阶段、系统结构及功能研究阶段和实质性推进阶段；进而，从源于互联网理念发展而来的能源互联网、源于大电网理念发展而来的能源互联网和源于多种能源综合利用理念发展而来的能源互联网对比剖析了能源互联网的基本内涵，提出了能源互联网的定义：能源互联网是一种互联网理念、技术与能源生产、传输、存储、消费以及能源市场深度融合的新型生态化能源系统；最后，分别从能源互联网的架构、分类2个角度对能源互联网的特征进行了辩识，给出了物理基础、实现手段、价值实现和体制保障的能源互联网4层组成架构，并将能源互联网分为互联网形态的能源设施与互联网形态的能源服务两大类。

Research on Identification of Concept and Characteristics of Energy Internet

The Energy Internet has attracted wide attentions, while the understanding and perception of its concept and characteristics are varied at present. To explore the connotations of the Energy Internet and effectively support its substantial advancement, this paper analyzes the development process of the Energy Internet, which can be roughly divided into three stages, including conceptual inoculation and proposing stage, system structure and function research stage, and substantial promotion stage. In addition, the basic connotation of the Energy Internet is analyzed from three perspectives from which the Energy Internet comes, including the ideas of Internet, big power grid, and multiple energy utilizations. Then the definition of Energy Internet is given, i.e., the Energy Internet is a new type of ecological energy system that profoundly fuses the idea and technology of Internet, and the production, transmission, storage and consumption of energy, as well as the energy market. Finally, the characteristics of the Energy Internet are identified from both architecture and category perspectives. From the architecture point of view, the Energy Internet has a four-tier structure:physical foundation, means of realization, value realization and institutional guarantee. From the category perspective, the Energy Internet has two types:energy infrastructure with Internet form, and energy service with Internet form.
