摘要

电网信息物理系统中

信息系统失效与遭受的攻击可能造成物理系统的能量损失。针对这一问题

文中提出了一种考虑有效距离接近中心性的信息设备重要度评估方法。首先

将信息系统结构抽象为有权有向的拓扑图

使之适用于量化评估。其次

根据信息系统对物理系统可靠性的影响大小

计算拓扑图中各有向边的权重。在此基础上

引入有效距离的概念

计算各个节点的有效距离接近中心性

实现从能量损失角度对信息设备重要度的量化评估。最后

对测试系统进行了信息设备重要度排序

验证了所提方法的有效性。

Abstract

In the cyber-physical power system(CPPS)

the failure or malicious attack on cyber system may cause load loss in the physical system. To solve this problem

a method considering the effective distance based closeness centrality for analyzing the importance of cyber devices is proposed. Firstly

a weighted digraph is abstracted from the cyber system for quantitative analysis. Then

the weight of each edge is calculated based on the reliability influence of cyber system on the physical system. After that

the concept of effective distance is introduced to evaluate the closeness centrality via effective distance for each node

which can quantitatively analyze the cyber device importance from the perspective of load loss. Finally

by sorting the importance degrees of cyber devices in the testing system

the effectiveness of the method is verified. This work is supported by the Key Program of National Natural Science Foundation of China(No. 51537010)
