摘要:

电力系统在极端灾害下维持并恢复正常功能的能力取决于其韧性。考虑信息系统与电力系统的相互影响,提出了一种电力信息物理系统应对极端自然灾害的韧性增强策略。首先,建立了电力信息物理系统的极端自然灾害防御框架,展示在信息物理环境下的决策控制技术。在此基础上,提出电网预防分区方法,在预测防护阶段依据故障概率和拓扑连通度进行电网分区。然后,提出支路有功调整方法,用于降低灾害抵御阶段线路开断导致的支路功率越限和系统失稳的风险。针对灾后恢复,提出信息系统和电力系统协同恢复方法,以恢复停电负荷和故障线路。修改的新英格兰测试系统仿真结果表明,所提策略能够有效降低灾害风险,加快信息物理系统的恢复进度。

Abstract:

The ability of power systems to maintain and restore its functions under extreme disasters depends on their resilience. Considering the interaction between the cyber system and the power system, a resilience enhancement strategy for cyber-physical power system to cope with extreme natural disasters is proposed. Firstly, the defense framework of the cyber-physical power system for extreme natural disasters is established, and the decision control technology in the cyber-physical environment is demonstrated. On this basis, a preventive grid partition method is proposed, which is based on the fault probability and topological connectivity in the prediction and protection stage. Then, the adjustment method for active power of the branch is proposed to reduce the risk of power over limit and system instability caused by circuit breaking in the disaster prevention stage. For the post-disaster restoration, the collaborative restoration method for the cyber system and power system is proposed to restore the outage loads and fault lines. The simulation results of the modified New England test system show that the strategy can effectively reduce the disaster risk and accelerate the restoration of cyber-physical systems.
