Research On Modeling And Communication Network For Users Energy Management In Energy Internet

The highlight of problem such as ecological environment,energy structure and energy service model promote the concept of Energy Internet to be proposed.Energy Internet emphasizes the interconnection and sharing of entities.There will be a large number of renewable energy and electric vehicles accessing to the user's energy management,which is an important constituent entity of energy Internet.In order to achieve accurate monitoring for energy and interaction between systems,it need consider the energy supply and demand information about the production and use of energy,and the process need to be described in a standardized way.In addition,by describing the service modeling,the communication network that supports user energy management needs scalability,security and compatibility.Therefore,it is necessary to study the next-generation communication network architecture,and analyze the adaptability and feasibility of the architecture to optimize the energy management.This paper will firstly introduces the business modeling mechanism for energy Internet through analyzing the top-level information architecture of energy Internet,NIST and interoperation model,and then proposes the user energy management system with electric vehicle which includes renewable energy power generation and energy consumption,introducing the composition and function of the service,and gives the whole process of business modeling in the form of UML use case diagram according to the general method of business modeling for energy Internet.It provides standardized guidance for the building and deployment of business system.Then,according to the results of business modeling,the paper will analyze the shortcomings of the existing electric power communication network supporting the user's energy management.In view of the technical characteristics and advantages of SDN,including the separation of the control plane and data plane,the realization of network virtualization,rapid diagnosis,centralized control and QoS guarantee,the SDN-based communication network architecture will be proposed and the performance of the architecture in reliability,security and QoS guarantee is analyzed to illusion its applicability.Finally,simulation experiments on delay,reliability,security and QoS guarantee on Mininet simulation platform will be carried out.Simulation results verify the adaptability and advantages of SDN-based communication network architecture in supporting user energy management.
