多LAN端口能量路由器切换控制策略研究
|
摘要
能量路由器作为能源互联网中的核心设备,具有能量管理、能量变换和信息交互等多种功能,对能源互联网的运行起着关键作用。该文提出一种基于固态变压器的多LAN端口能量路由器,给出了其主电路拓扑结构,建立了其切换系统模型,并在此基础上进行切换控制策略的设计。仿真结果验证了所提主电路结构和切换控制策略的有效性。
As the core equipment of energy internet, energy routers have many functions such as the energy management, energy conversion and information interaction, which play a key role in the operation of energy internet. In this paper, a multi-LAN port energy router based on the solid state transformer is proposed. The main circuit topology is given, and its switching system model is established. Then, the design of switching control strategy is designed based on the proposed model. The simulation results verify the effectiveness of proposed main circuit structure and switching control strategy.
