Design Of Energy Router For Community Network And Research On Its Routing Strategy

In recent years,there is a certain degree of energy research on Energy Internet both at home and abroad,and research related to energy router(Energy Router/Hub)is one of the important content.Thesis has studied on three aspects,including the structure and function of the energy router,stream energy technology deployment and routing strategy.Achieved results is as follows.1)Thesis presents the basic structure of community energy networks.Energy router is designed as its smallest terminal,controlling and scheduling home electrical system.Based on the analysis of power router design requirements,the proposed solid state transformer-based energy router features plug-and-play,Multiple-Input and Multiple-Output(MIMO),connecting,controlling and scheduling renewable energy resources,energy storage devices and loads of the home electrical system.2)According to the different energy flow,the different forecast models are raised.Based on the different types of energy flow and the typical routing strategy in local energy network,the final forecast model for energy flow is raised.This model will show the short term range of energy flow.The simulating experiments illustrate the feasibility of this model,and also simulate the energy flow under six different situations.The results finds the rules of energy flow.When storage devices and distributed power has sufficient capacity,energy flow is minimum,to achieve regional self-sufficiency.When energy storage device capacity is limited,there is a critical distributed power capacity enables the flow to a minimum.3)For there are two issues on the energy internet,which are "congestion control" and "load balancing".The ideal models for energy Internet and energy flow transmission are proposed based on the BA scalefree networks.On this basis,the merits of the traditional routing policy used to energy Internet is analyzed.And the united routing strategy for energy Internet is proposed.Finally,it should be considered in the design of standard solid transformers,plug the interface and using equipment and other structural aspects of unification,energy flow management solutions on the community level,real-time energy trading price system and other aspects of the deployment of the energy flow,establish demonstration projects,using the actual data continue to study the practical aspects of verification of routing strategy.
