摘要
2016至2023年间,美国、英国和澳大利亚发生了11起新能源大规模脱网事故,严重威胁电网安全稳定运行。文中介绍了这些事故的基本情况,总结分析了事故失稳过程和机理特征,并指出系统强度不足、新能源控制策略不合理、非预想故障防控手段不足是事故产生的主要原因。最后,结合中国电网实际,提出了保障新型电力系统安全稳定运行的建议。
From 2016 to 2023,eleven significant outage accidents related to the renewable energy occurred in the United States,Australia,and the United Kingdom,which posed severe threats to the secure and stable operation of power grids.The basic situation of these accidents are introduced,and their instability process characteristics,and mechanism are summarized and analyzed.It identifies the insufficient system strength,irrational renewable energy control strategies,and a lack of unanticipated fault prevention measures as the primary reasons for these accidents.Finally,combined with the reality of the power grids in China,some recommendations are proposed to ensure the secure and stable operation of the new power systems.
