A cyber physical power system model based on the weighted tensor product is proposed in this paper to describe the interlayer and intralayer relationships of entities in both systems. The different functional attributes of nodes and the directivity of the energy flow in the system are respectively described as the heterogeneity of nodes and the directionality of edges. During failure propagation, the dynamic topology method is applied to convert the protection strategies and load redistribution measures into system connectivity rebuilding. The simulation results of fault propagation in the cyber physical power system under different initial failure ratios show that, compared with the undirected model, the directional interactions in the proposed approach can significantly improve the system survival rate during cascading failure. In addition, the physical system shows a lower vulnerability due to the protection provided by spare edges and power sources.

提出了一种基于加权张量积的网络物理电力系统模型，描述了两个系统中实体之间的层间关系。节点的不同功能属性和系统中能量流的方向性分别描述为节点的异质性和边缘的方向性。在故障传播期间，使用动态拓扑方法将保护策略和负载重新分配措施转换为系统连接重建。在不同初始故障率下，网络物理电力系统故障传播的仿真结果表明，与无向模型相比，该方法的方向性相互作用可以显着提高级联故障时的系统存活率。此外，
