面向电力信息物理系统的端边云雾协同模型

Cloud-fog-edge-end Collaboration Model for Cyber Power Physical System

随着电力物联网的推进,海量终端设备的接入对传统集中式控制方式下电力信息物理系统CPPS(cyber power physicalsystem)提出了极大的挑战。在边缘计算与雾计算的发展背景下,基于“云、网、边、端”电力物联网体系架构,提出了端边云雾协同控制下的CPPS模型,并考虑了分布式信息能源系统海量时空异构特征数据处理,结合矩阵分析单雾层级区域计算单元CPPS建模,建立了多层级分布式全网CPPS关联模型。通过算例分析量化计算了区域自治与端边云雾协同控制下的电网运行状态和通信网络时延特性,算例分析结果表明了所提架构的有效性与建立模型的合理性。

With the promotion of power internet of things(IoT),the access of massive terminal devices poses a great challenge to the cyber power physical system(CPPS)in the traditional centralized control mode.Under the development background of edge computing and fog computing,a CPPS model under the cloud-fog-edge-end collaborative control is proposed,which is based on the architecture of“cloud,network,edge,and end”power IoT system.In addition,the massive spatiotemporal heterogeneous characteristic data processing of the distributed information energy system is considered.Combined with the matrix analysis of single fog-layer regional computing unit CPPS modeling,a multi-layer distributed network CPPS joint model is established.The power grid operation status and communication network delay characteristics under the regional autonomy and cloud-fog-edge-end collaborative control are quantitively calculated through the analysis of a numerical example,which illustrates the validity of the proposed architecture and the rationality of the established model.
