摘要:

制定有效的策略来保护电力系统免受蓄意攻击是一项重大任务。必须全面考虑与人类和环境有关的风险和不确定性,这是现有文献所缺乏的。本文考虑了负荷需求的不确定性和风力发电的不确定性,除了相互作用的攻击者/防御者的行为。具体而言,防御者-攻击者-自然-运营商模型,它结合了攻击/防御的相互作用,正确的重新调度的运营商,攻击策略之间的协调和随机性质的负载需求和风力发电。采用列和约束生成(C&CG)算法求解该模型,将模型分解为主问题和子问题。使用MATLAB和CPLEX在修改后的IEEE RTS 79系统上进行仿真。仿真结果验证了该模型的有效性。

英文摘要:

It is a major task to develop effective strategies for defending the power system against deliberate attacks. It is critical to comprehensively consider the human-related and environmental risks and uncertainties, which is missing in existing literature. This paper considers the load demand uncertainties and wind generation uncertainties in addition to the interactive attacker/defender behaviors. Specifically, a defender-attacker-nature-operator model is proposed, which incorporates the attack/defense interaction, the corrective re-dispatch of the operator, the coordination between the attack strategy and the stochastic nature of load demands and wind generations. The Column-and-Constraint Generation (C&CG) algorithm is adopted for solving the proposed model by decomposing the proposed model into a master problem and a sub-problem. Simulations are performed using MATLAB and CPLEX on a modified IEEE RTS79 system. The simulation results verify the validity of the proposed model.
