| 摘要: |
| 在极端自然灾害愈加频发的背景下，电网调度人员不仅需要考虑如何调度维修资源加快电力信息物理系统的恢复，还需要考虑如何降低引发的次生灾害造成的负面影响。针对上述问题，提出了一种计及次生灾害影响的电力信息物理系统恢复方法，根据信息物理协同的特点和次生灾害发生的概率调度维修资源至受灾区域，减少停电损失。首先，建立了基于以太无源光纤网络和应急电源协同的电力信息物理系统模型，研究信息网络和物理网络对系统韧性提升的效果。然后，提出了一种计及次生灾害影响的协同维修方法，并与单独维修方法进行对比。最后，搭建了一种求解所提恢复方法的分析框架，并在IEEE 33节点系统上进行仿真，确定最佳的维修资源调度策略。仿真结果表明，所提方法能降低次生灾害造成的负面影响、提高维修资源的利用率。 |

| Abstract: |
| As extreme natural disasters become more frequent, grid dispatchers not only consider how to dispatch repair resources to accelerate the recovery speed of cyber physical power system, but also need to reduce the negative impact of secondary disasters caused by extreme natural disasters. To solve the above problems, a recovery method considering the impact of secondary disasters is proposed. It dispatches the maintenance resources to the affected areas based on the characteristics of cyber physical collaboration and the occurrence probability of secondary disasters to reduce power losses. First, a cyber physical power system model based on the coupling of Ethernet passive fiber optic network and emergency power supply is established, and the effect of cyber physical system on resilience enhancement is researched. Then, a coordinated repair method considering the impact of secondary disasters is proposed, and compared with individual repair methods. Finally, an analytical framework for method solving is proposed, and it is simulated on the IEEE 33-node system to determine the optimal repair resource dispatching strategy. The results show that the proposed recovery method can reduce the impact of secondary disasters and improve the utilization of maintenance resources. |
