分布式协同控制模式下配电网信息物理系统脆弱性评估
Vulnerability Assessment for Cyber Physical System of Distribution Network in Distributed Cooperative Control Mode
摘要
Abstract
Distributed cooperative control mode is an effective approach to overcome the problem of integrating multiple and strongly random distributed generators (DGs) into cyber physical system in distribution network.However,due to the integration between cyber and physical layers,cyber attacks could threat the safe and stable operation of power system through invading the cyber system.A dynamic attack-defense game model based vulnerability assessment of cyber-physical system (CPS)in distribution network is proposed.Firstly,a cooperative control strategy of DGs is described,and its convergence property is analyzed and summarized.Then,a risk assessment of CPS in distribution network is developed,which integrates the risk assessment method,the cooperative control strategy of DGs and strategies of attacker and defender.After that,the dynamic attack-defense game function and its solving steps are designed,which achieves the vulnerability assessment of CPS in distribution network with distributed cooperative control mode.Finally,the effectiveness of the proposed method is verified through simulations involving the IEEE 34-bus distribution network.关键词
