电能路由器的发展及其关键技术

The Development and Key Technologies of Electric Energy Router

随着能源互联网的概念和实践迅速发展,同时也伴随着电力电子技术的快速进步,人们相继提出电子变压器、智能变压器、电力电子变压器及能量路由器等相关概念。该文对这些概念进行综述和梳理,总结电能路由器的发展历程。根据对能源互联网的设想及对电能路由器的需求,分别从电力系统和电力电子技术的角度阐述电能路由器的基本架构和基本功能。针对其在能源互联网中的应用,进一步从电能变换技术、通信技术和能量管理技术3个方面对电能路由器中的关键技术和功能应用进行阐述。最后介绍电能路由器在能源互联网中的一种典型组网形式。

With the rapid development of energy intcrnet and also power electronics, the related concepts of electronic transformer, intelligent transformer, power electronic transformer, energy router and others have been proposed. In this paper, these concepts were sorted out and reviewed. Based on the demands for energy internet, the paper expatiated the background and basic concept of electric energy router from the view of both power system and power electronics, respectively. Furthermore, three key technologies of the electric energy router which include power conversion, communication and energy management were expounded. In the end, a typical network configuration with electric energy routers was introduced for energy internet applicationsl
