摘要

分布式协同控制模式的提出，为解决未来配电网信息物理系统(CPS)中高密度、强随机性分布式电源接入问题提供了途径。但同时，配电网CPS信息物理高度融合的特点也方便了网络攻击者通过信息系统威胁电力系统的安全稳定运行。据此，提出一种基于动态攻防博弈的分布式协同控制模式下配电网CPS脆弱性评估方法。首先，阐述了一种分布式电源等输出比协同控制策略，并对其收敛特性进行了分析和总结。其次，基于CPS风险评估框架，结合分布式电源协同控制策略及实际网络攻防策略的特点，提出配电网CPS风险评估模型;在此基础上，设计动态攻防博弈函数及博弈求解步骤，实现对于分布式协同控制模式下配电网CPS脆弱性的量化评估。最后，基于IEEE 34节点配电系统开展仿真测试，验证了所提方法的有效性。

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. Toward this end

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.
