摘要

韧性用于评估在遭受严重冲击后的系统性能的维持和恢复能力，是智能电网的重要性能指标之一，文中提出了一种考虑网架重构和灾区复电过程的配电网抗台风韧性评估模型。根据不同等级台风灾害造成的配电网设备故障率分布函数及不同等级台风灾害的发生概率，同时考虑集中型、分散型、集中分散型3种常见故障设备分布方式，生成台风灾害影响下的配电网设备故障场景集合；评估各场景在“灾害发生-网架重构-灾区复电”全过程中配电网保证负荷供电的能力，并通过吸收率、适应率和修复速率3个综合指标来对韧性进行量化描述。最后，以IEEE 33节点配电系统为例，详细介绍了韧性评估的建模和计算过程，验证了该模型用于评估配电网韧性的可行性。

Abstract

Resilience is used to assess the ability to maintain and recover system performance after a severe impact

which is one of the important performance indicators of smart grid. A model for evaluating the typhoon resilience of distribution network is proposed considering grid reconstruction and disaster recovery. According to the distribution function of distribution equipment failure rate caused by different levels of typhoon disaster and the probability of different levels of typhoon disaster

the failure scene set of distribution network equipment is formed under the influence of typhoon disaster. Three modes of the centralized

decentralized and centralized decentralized are considered in the set. The ability of the distribution network is assessed to guarantee the load supply in the whole process of “disaster occurrence to grid reconstruction to disaster recovery”

and the resilience is quantified by three aggregative indicators of absorbing capacity

adaptive capacity and repair capacity. Taking an IEEE 33-bus system as an example

the modeling and calculation process of resilience evaluation are introduced in detail for illustrating the feasibility of the model proposed to evaluate the resilience of distribution network.
