Abstract

The power outages caused by extreme events are becoming more frequently and damage the distribution networks in recent years. Therefore, the concept of resilience was proposed to measure the performance of the distribution systems in high-impact and low-probability (HILP) events. In this paper, we propose an explicit resilience assessment model for the distribution networks. For HILP events, an explicit formulation model is proposed to describe the evolution of the distribution system from the contingencies occurrence to system recovery, in which the actions of protection and switch equipment, such as circuit breakers, automatic switches and manual switches, are fully considered. Based on this formulation, an explicit resilience assessment model considering the maintenance resource constraints is developed, which embeds the optimization of outage recovery sequence. The resilience assessment model is finally cast as an instance of mixed integer linear programming (MILP). Case study on the modified IEEE 33-node and IEEE 123-node systems is performed and the effectiveness of proposed method is verified.

具有任意保护和开关设备配置的配电系统显式弹性评估模型

近年来，由极端事件引起的停电日益频繁，并对配电网造成破坏。因此，提出了弹性的概念来衡量配电系统在高影响低概率（HILP）事件中的性能。在本文中，我们提出了一个显式的配电网络弹性评估模型。对于HILP事件，提出了一个明确的公式模型来描述配电系统从事故发生到系统恢复的演变过程，该模型充分考虑了断路器、自动开关和手动开关等保护和开关设备的作用。在此基础上，建立了考虑维护资源约束的显式弹性评估模型，该模型嵌入了停机恢复顺序的优化。最后将弹性评估模型作为混合整数线性规划（MILP）的一个实例。以改进后的IEEE 33节点和IEEE 123节点系统为例，验证了所提方法的有效性。
