Characteristic Analysis Of Information Flow In Software Defined Energy Internet

Energy is an important material basis for the survival and development of human beings.Energy internet has become a hot research topic as a solution to the sustainable development of energy in the future.Among them,the related research on energy Internet architecture design is the most important for the development of the energy Internet.The traditional architecture design idea that the system and equipment are closely coupled can no longer meet the business needs of the energy internet.Peer-to-peer energy exchange and sharing requirements energy internet has the same free and flexible architecture as the Internet.Therefore,we use the concept of software definition network to study the energy Internet architecture,and analyze the basic characteristics of the information flow.First,based on a brief review of the connotation,goals and significance of the energy Internet,we make a comparative analysis of the research status of the energy Internet architecture at home and abroad.Combining the existing architecture design results and introducing the idea of software definition,a model of energy Internet architecture based on the technology of software defined technology is presented.By redefining the four core devices of the energy Internet architecture,such as intelligent control unit,energy router,switch and controller,we introduce the specific working mode,architecture features and shortcomings of the energy Internet architecture in detail.Among them,the function and structure characteristics of the control plane,the data plane and the energy plane are emphatically expounded.It provides new ideas and possibilities for the development and construction of the energy Internet.Subsequently,in order to develop the software defined energy Internet architecture scientifically,and the energy Internet standard system developed quickly.Based on the results of the standard of classification of IEC,IEEE and other international standards organization,the main structure of the software defined energy Internet standard system is basically established,and the key object model of basic information communication is given according to the existing smart grid standard system.It lays the foundation for the further analysis of the energy Internet information flow.Finally,the structure of the information flow and the main type of message in the basic information communication network are explained.The network calculus theory is used to model the information flow in the communication link of key equipment,and the static calculation method is given.By building Mininet and Floodlight experiment environment,we analyze the dynamic performance of information flow in the designed architecture from four perspectives: queuing strategy,exchange path,flow control strategy and synchronization process.It provides a basis and reference for the research and practice of the software definition of the energy Internet.
