摘要:
      能源路由器是构成未来能源互联网的重要设备。在分析基于能源路由器的分布式能源共享方式的基础上,分析了能源互联网对能源路由器的基本要求,并提出了一种基于电力电子变换器的模块化多接口能源路由器主回路结构,包括储能及其变换器,公共直流母线和能源接口,其中能源接口根据其用途可分为网络能源接口和本地能源接口。简要介绍了能源路由器各个模块的控制策略,在相应控制策略下,能源路由器一方面能够满足本地分布式电源的接入和负荷的供电需求,另一方面能够控制其多个网络能源接口的交换功率,实现多个能源路由器之间或与外部电网之间能量的点对点传输,即能源路由功能。提出了一种能源路由器储能和各网络能源接口之间的能量管理策略,能够实现分布式电源就地消纳及能源的网络共享。在MATLAB/Simulink环境下建立了能源路由器仿真模型,对能源路由器的动态响应特性和能量管理策略进行了仿真,结果验证了所提出的能源路由器主回路结构及控制策略的正确性和有效性,验证了能量管理策略的可行性。
Abstract:
      The energy router is an important device for the future Energy Internet. Based on an analysis of the energy sharing method using the energy router in the Energy Internet environment, the basic requirements of the energy router are analyzed, and a multi-interface energy router main circuit structure based on power electronic converters is proposed. The proposed energy router consists of energy storage and its converter, common DC bus and energy interface. According to the application, the energy interface can be divided into network energy interface and local energy interface. The control strategies of the modules in the energy router are briefly described. With the control strategies, an energy router can provide the access interface for the local distributed energy resources and supply the local load. Meanwhile, the energy router can control the exchange power of its network energy interface, and realize the point to point energy transmission between energy routers or between the energy router and the external power grid, which means the energy routing function is realized. An energy management strategy for energy storage and network energy interface is proposed. The energy router simulation model is established in the MATLAB/Simulink environment. The dynamic responses of the energy router and the energy management strategy are simulated, the simulation results verifying the correctness of the energy router main circuit and control strategy as well as the feasibility of the energy strategy proposed.
