【摘要】 电力路由器融合了信息技术和电力电子变换技术,为分布式能源大范围地接入能源互联网提供了条件,但也给能源互联网的优化运行提出了新的要求。以图论为手段,以能源互联网的结构为基础构成单源点单汇点的电能路由拓扑;以Dijkstra为基础,节点仅根据其相邻节点的状态调节其自身状态,搜寻最短路径,完成电能路由,实现电能的分布式管理和协调控制,使系统运行在优化状态。多代理系统(multi-agent system,MAS)技术为实现分布式电能路由策略提供了技术支撑。最后,在Matlab/Simulink平台下搭建了分布式电网,结合基于JADE(Java Agent DEvelopment framework)平台的多代理系统对分布式电能路由策略进行仿真实现。更多还原

【Abstract】 Power router, combining information technology and power electronic technology, provides probability for large-scale penetration of decentralized renewable energy resources, while putting forward new requirements to optimization of energy internet operation. In this paper, power routing strategy is presented, where a topology with one source point and one sink point is derived from energy internet architecture based on graph theory. Based on Dijkstra algorithm, each node adjusts its state just according to states of adjacent nodes for searching the shortest path to implement power routing and achieve function of energy management and cooperative control to optimize system operation. Multi-agent system(MAS) technology provides technical support for implementation of distributed power routing strategy. Finally, a hybrid simulation model is built, consisting of a MAS and a distributed grid. The MAS is modeled on Java agent development framework(JADE) and the distributed grid is modeled on Matlab/Simulink platform. The proposed strategy is verified with simulation.更多还原
