摘要
首先对能源互联网的背景及面临的关键问题进行了阐述;在此基础上对能源互联网的信息物理架构及其上支撑能源信息数据应用的云端架构进行了研究,指出云架构在能源信息数据共享与同步上存在的一致性问题;通过对能源互联网典型场景信息能源一体化架构的研究,提出了面向能源互联网的数据一致性框架,介绍了支持框架实现的一致性协议;最后,通过仿真试验从一致性处理的吞吐量和框架的可扩展能力两个角度对数据一致性框架进行了评估,反映了框架在实现数据一致性以及支撑能源信息数据同步共享方面具有良好的表现。
The paper firstly states background of the energy internet and its critical problems, then studies its cyber-physical architecture and the cloud architecture supporting energy information data application. And it analyzes and points out the problem of consensus in energy information data sharing and synchronization of the cloud architecture. On the basis of stud-ying the integrated infrastructure for cyber-energy, a typical scene of the energy internet, it proposes an energy internet or0- ented data consensus framework and introduces the consensus protocol that enables realization of the framework. Finally, in aspects of throughput for consensus processing and scalability of the framework,it evaluates the data consensus framework by means of simulating experiment and shows this framework has good performance in realizing data consensus and support-ing synchronous sharing of energy information data.
