Abstract

Enhancing power system resilience against extreme events is becoming increasingly critical. This paper discusses a unified framework for preventive control of power systems to enhance system resilience, which includes three parts: resilience assessment, resilience grading, and resilience enhancement. First, the resilience assessment contains facility-level and system-level resilience assessment. The concept of fragility curve is used in the facility-level resilience assessment. Various resilience indices are developed in system-level resilience assessment to roundly depict the impacts of extreme events on power systems and determine the system resilience. On this basis, the resilience is divided into different levels by resilience grading strategy, which can efficiently quantify the severity of the impact of extreme events and provide decision-making for the resilience enhancement strategies. Then, control strategies for enhancing power system resilience are also divided according to different resilience levels. A controlled islanding based preventive control is proposed to enhance system resilience, which aims to strengthen the first defensive line of power systems to deal with extreme events. Finally, taking the typhoon disaster in extreme events as an example, two tests carried out with two typhoons demonstrate the efficiency of the proposed method.

防御极端事件的电力系统预防性控制框架

提高电力系统抵御极端事件的能力正变得越来越重要。本文讨论了一个统一的电力系统预防性控制框架，以增强系统的复原力，该框架包括三个部分：复原力评估、复原力分级和复原力增强。首先，复原力评估包括设施级和系统级复原力评估。设施级复原力评估采用脆性曲线的概念。在系统级复原力评估中，制定了各种复原力指数，以全面描述极端事件对电力系统的影响，确定系统复原力。在此基础上，通过弹性分级策略将弹性划分为不同等级，从而有效量化极端事件影响的严重程度，为弹性增强策略提供决策依据。然后，增强电力系统恢复力的控制策略也根据不同的恢复力等级进行划分。提出了一种基于可控孤岛的预防性控制来增强系统韧性，旨在加强电力系统应对极端事件的第一道防线。最后，以极端事件中的台风灾害为例，通过两次台风试验证明了所提方法的有效性。
