摘　　要：针对现有技术中新能源电网评估不足和能源调配不合理问题,通过设计“主干网”和“局域网”,将主干网或者微网设计成分布式能源互联网网络架构,使分布式能源以开放对等的形式构成信息能源一体化系统。研究还实现了分布式能源互联网双向按需传输和动态平衡使用,从而能够将不同形式的新能源有序接入、转换和应用;设计了配电数据信息融合算法模型,提高了配电网资产运行效率;通过基于灰色GM(1,1)模型的电网高弹性分析方法,实现了多种不同能源互联网架构的数据分析与计算。试验表明,所提方法数据融合能力强,评估误差率低。Giving considerations to the problems of inferior evaluation for new energy-connected power grids and improper energy allocation in the existing technology,this work aims at the establishment of an information-energy integrated system in which the distributed energies are open and peer-to-peer with each other,by introducing the concept of"backbone network"and"local area network",and by designing backbone network or micro-grids as a distributed energy Internet architecture.It realizes two-way on-demand transmission and dynamic balanced usage,which enable ordered access,conversion and application of different forms of new energies.An algorithmic model for data information of power distribution is also proposed to improve the operation efficiency of distribution network assets.Moreover,data analysis and calculation of various architectures of energy Internet are conducted through analysis of power grid resilience based on grey GM(1,1)model.Experiments show that the proposed method has strong data fusion ability and low error rate.
