| With the continuous reduction of non-renewable energy,environmental issues have become increasingly prominent.In order to meet the needs of the sustainable development of the society and to promote the development of the energy network,the concept of the energy internet has emerged.Energy router is one of the most important devices in the energy internet.It is called the brain and the core of the energy internet.In this paper,the energy router for the energy internet has been deeply studied.The specific research contents are as follows:This paper firstly introduces the background and significance of the research,summarizes the research status and development trend of the energy Internet and energy router,and analyzes the key technical difficulties in the research of energy router.Then,this paper introduces the common four types of energy router,according to the scope of application of the energy router,and combined with the practical application,the role of energy router in different levels and the corresponding hardware topology are given.And analyzes the functional requirements of the energy router.The operation mode of energy router is classified and summarized.Secondly,the corresponding control method is presented for the main circuit of power electronic transformer.Aiming at the problem of stochastic power fluctuation of distributed generation on the power grid caused,this paper proposes a control method based on smooth switching power,to ensure smooth flow of energy between the router and the power grid power bus on the bus,effectively reduce the random fluctuation,improve grid quality.In view of the large number and complex types of distributed devices,this paper proposes a coordinated optimization control method based on multi agent.Finally,for the research of energy router system,a hardware experiment platform based on DSP TMS320F28335 is built.The hardware and software of the system are designed,and the experimental waveforms are given.The results of this study are verified. |
