摘要
近年来,电力系统呈现高比例可再生能源和电力电子装备接入、负荷多元化、信息-物理高度融合等特点,且来自内外部的安全威胁增多,电网安全形势严峻。该文立足于我国电网发展现状和面临的挑战,结合我国传统文化和国内外相关领域研究现状,提出了"韧性电网"定义,即"能够全面、快速、准确感知电网运行态势,协同电网内外部资源,对各类扰动做出主动预判与积极预备,主动防御,快速恢复重要电力负荷,并能自我学习和持续提升的电网"。首先介绍"韧性"一词的释义和应用,简要总结国内外电力系统韧性相关概念;进而提出韧性电网的定义,并阐述其内涵和关键特征;进一步分析韧性电网的概念范畴,并阐明韧性电网与能源互联网的关系;最后探讨韧性电网领域的研究需求。
In recent years, power systems present several new features, including high penetration of renewables, power electronic equipment integration, load diversity, and cyberphysical interdependency. In addition, the security threats are increasing, and the security situation of power grids becomes severe. Based on the current development of the power grid in China, this paper proposed a definition of "resilient power grid." A resilient power grid can comprehensively, quickly and accurately sense the operation status, cooperate with the internal and external resources of the power grid, proactively anticipate and prepare for various disturbances, defend and quickly restore critical loads, and learn to continuously improve itself. This paper first introduced the meaning and application of the term "resilience" and briefly summarized concepts related to power system resilience. Then, resilient power grid was defined and explained. Further, the meaning and key features of resilient power grid and its relationship to energy internet were clarified. Finally, research needs on resilient power grids were discussed.
