摘要
2020年8月14日至8月15日美国加利福尼亚州(下文简称加州)发生轮流停电事故,同年8月17日至8月18日和9月5日至9月6日,加州电网进入紧急状态,至少81万居民用户的正常用电受到影响。加州电力系统运营商(CAISO)关于该事件的事故分析报告指出,此次事故由一系列因素共同导致。文中结合CAISO的公开报告,梳理并总结了事故的发展过程,分析了此次事故的成因,最后结合中国电网实际情况,提出了关于提前预防极端天气、重点关注需求响应常态化、合理推进2060年碳中和发展战略、稳步提升跨区域电力调度能力的建议。
From August 14 to August 15,2020,a rotating power outage occurred in California,USA.From August 17 to August 18 and from September 5 to September 6 of the same year,the California power grid entered a state of emergency,affecting the normal electricity usage of at least 810000 residents.Accident analysis report of the California Independent System Operator(CAISO)pointed out that the accident was caused by a series of factors.Based on the public reports of the CAISO,this paper sorts out and summarizes the development process of the accident,and analyzes the causes.Finally,combined with the actual situation of the power grid in China,suggestions on prevention of extreme weather,focusing on normalizing demand response,making steady progress toward the carbon neutral goal in 2060,and improving cross-regional power dispatching capability are put forward.
