摘要
在分析电网信息物理系统(GCPS)逻辑结构的基础上,提出一种基于集合论的GCPS交互建模方法。通过剖析电力能量流与信息流的耦合方式,将GCPS定义为物理对象集合与信息对象集合之间的关系。分解GCPS为电源子系统和负荷子系统,从输入、输出和状态三方面描述其行为水平与状态结构水平,并建立子系统的网络结构图。在当前电网拓扑结构的约束下,采用"纵向金字塔汇集、横向逻辑互联"的组网规则,实现GCPS子系统的逐级耦合与互联,构建完整的GCPS架构。对典型测试系统的案例分析说明了GCPS模型的有效性和应用价值。
On the basis of analyzing the logical structure of cyber physical system for power grid（GCPS）,we proposed a modeling method of GCPS using the set theory.By studying the coupling principle of power flow and information flow,the GCPS was defined as the interconnection between the set of physical objects and the set of information objects.Then,the GCPS was decomposed into the power subsystem and load subsystem,which were described from the aspects of input,output,state changes and network structure.Under the constraints of the existing power grid network,subsystems were connected in accordance with rules from different perspectives to form the complete GCPS model.The case study of a typical power system shows the validity and significance of the proposed method.
