Quantitative vulnerability assessment of cyber security for distribution automation systems

摘要: The distribution automation system (DAS) is vulnerable to cyber-attacks due the widespread use of terminal devices and standard communication protocols. On account cost defense, it impossible ensure security every device in DAS. Given this background, a novel quantitative vulnerability assessment model cyber for DAS developed paper. In model, potential physical consequences are analyzed from two levels: level control center server level. Then, attack process modeled based on game theory relationships among different vulnerabilities by introducing adjacency matrix. Finally, application proposed methodology illustrated through case study bus 2 Roy Billinton Test System (RBTS). results demonstrate reasonability effectiveness methodology.
