韧性背景下的配网故障恢复研究综述及展望

A Review on Distribution System Restoration for Resilience Enhancement

近年来全球范围内由极端事件引发的大停电事故不断发生,造成巨大损失的同时也暴露了电力系统应对极端事件的脆弱性。韧性被用于描述系统预防和适应环境变化、承受扰动以及快速恢复的能力。快速有效的故障恢复是提升配电网韧性的重要手段。该文首先简要介绍和总结韧性定义内涵和配电网韧性提升方法,然后针对能够直接有效提升配电网韧性的方法之一——配电网故障恢复方向的研究进行了综述。在分析韧性背景下配电网故障恢复问题描述及关键问题的基础上,分别从恢复思路和求解方法两方面对现有的配电网故障恢复研究工作进行综述。最后从提升能源互联网韧性的角度分析论述值得深入研究的关键问题和发展方向。

In recent years,the blackouts due to extreme events have happened frequently worldwide,which bring about huge losses and reveal the vulnerability of power systems.Resilience describes the ability of a system to prevent and adapt to condition changes,to withstand disturbances,and to recover quickly.Efficient service restoration is an important measure to enhance distribution system resilience.Firstly,the connotation of resilience is introduced,and the measures to improve distribution system resilience are reviewed.Then,as one of the measures that can directly improve resilience,the research on distribution system restoration is reviewed in detail.After describing the distribution system restoration problem for resilience enhancement and the key issues,the associated studies are reviewed by two aspects:restoration idea and solution method.Finally,future study on service restoration for energy internet resilience enhancement is discussed.
