Assessing the Harmfulness of Cascading Failures Across Space in Electric Cyber-Physical System Based on Improved Attack Graph
摘要
Abstract
In order to accurately assess the harmfulness of cascading failures across space in electric cyber-physical system (ECPS), a quantitative assessment method based on improved attack graph was proposed. Firstly, for quantitative analysis, the attack graph algorithm was improved by the way that put forward the vulnerability factors of attack graph vertexes and deduced their calculation formulas. And then, to identify all kinds of cascading failures across space, all kinds of ECPS security risks, which include cyber attacks, power secondary equipments faults and power system disturbances, are abstracted into the improved attack graph vertexes to build the logical relationship between each step of cascading failures across space. After that, the vulnerability factor of each vertex was calculated to quantitative assess the harmfulness of cascading failures across space. Finally, to verify the validity of this quantitative assessment method, a local ECPS model has been built based on the 110 kV smart substation simulation, and a several cascading failures across space have been simulated and assessed those harmfulness.关键词
