面向新型配电系统的网络安全脆弱性评估
Network Security Vulnerability Assessment for New Distribution Systems
摘要
Abstract
With the construction progress of new distribution systems,the level of networking and intelligence of new distribution systems is becoming increasingly high,and the security risks of cyber attacks on the information and physical systems of distribution networks are increasing.This paper proposes a cross spatial risk quantification assessment method to address the issue of information side security risks and vulnerabilities in new distribution systems that cannot be quantitatively evaluated.Firstly,a new distribution system network risk assessment model is established,and an improved Moody's diagram based analytic hierarchy process(MSDM-AHP)is used to construct a weight matrix to solve the problem of inaccurate indicator weights in traditional analytic hierarchy process.TOPSIS algorithm is used to quantify the vulnerability factors of nodes and calculate the attack probability of the attack target.Finally,the effectiveness and accuracy of the proposed method are verified by establishing a new substation information model for distribution systems based on the IEC61850 standard.关键词
