面向能源互联网的电能路由器研究

Research on electrical energy router for energy internet

基于未来电网中电能控制的复杂程度和多样性,提出了能源互联网的概念。在由现有大电网、分布式能源以及储能装置等构成的能源互联网中,供电具有多样性,能量流动具有双向流动甚至多向流动等特点。为了解决电能智能控制的复杂性与多样性,基于电力电子变换技术的电能路由器应运而生。对能源互联网的发展现状、国外研究机构应用于电能路由器的相关拓扑进行了介绍,具体分析了几种典型的电能路由器的应用拓扑结构。最后,结合当前现状,提出了电能路由器未来发展建议。

Based on the complexity and diversity of power control in future power grid,the concept of energy internet is proposed.The energy internet composed of the existing large grid,distributed generation and energy storage devices,power supply has diversity,and energy flow has the characteristics of bidirectional flow and even multi-directional flow.In order to solve the complexity and diversity of power intelligent control,electrical energy router based on power electronic conversion technology is born at the right moment.In this paper,the development status of energy Internet and the related topology of domestic and foreign research institutions applied to electric energy routers are introduced,the topological structure of several typical electric energy routers are analyzed concretely.Finally,combined with the current situation,the future development of electrical energy router is proposed.
