摘要

近年来，高比例新能源电力系统级联故障的研究逐渐受到重视。结合级联故障的定义和分类，分析了新能源发电并网后电力系统级联故障的特点。并从新能源发电并网和新能源发电机级联脱扣后的不确定性分析角度，收集了新能源系统级联失效机理的研究现状。对系统中不同时间尺度的广域控制措施进行了集成。级联故障综合防御方法分为组件强化、运行状态优化和级联故障阻断控制三个部分。讨论了新能源并网系统级联故障研究中的关键技术问题。

Summary of research on cascading failures of high proportion new energy power systems

In recent years, the research on cascading failures of high proportion new energy power systems has gradually attracted attention. Combine the definition and classification of cascading failures, the characteristics of power system cascading failures after the connection of new energy generation is analyzed. And, from the perspective of the uncertainty analysis after the connection of new energy generation and the cascading trip-off of new energy generators, the status of the research on the mechanism of cascading failures in new energy systems is collected. Wide area control measures at different time scales in systems are integrated. The comprehensive defense method of cascading failures is divided into three parts: component strengthening, operating state optimization and cascading failure blocking control. The key technical issues in the study of cascading failures in new energy grid-connected systems are discussed.
