摘要/Abstract

摘要：

2021年2月15—19日，美国得克萨斯州（简称“得州”）电网出现了轮流削减负荷运行的停电事故，引起了全球广泛关注。介绍了得州电网、电力市场概况，以时间为主线梳理了停电事故的发生与发展过程，以及事故期间的电力市场运行状况，初步分析了事故中供需不平衡、高电价、财务危机三大问题产生的原因。最后，总结停电事故的经验教训，提出对我国电力市场建设的相关启示。

关键词: 美国停电, 削减负荷, 电力市场, 稀缺定价

Abstract:

From February 15 to 19, 2021, a rotating outage due to load-shed occurred in the power grid of Texas in the United States, causing widespread global concern. In this paper, an overview of the power grid and electricity market in Texas was introduced firstly. Then, this paper sorted out the occurrence and development process of the accident with time as the main line, and paid attention to the operation status of the electricity market during the accident period. Moreover, the causes of the three major problems such as imbalance between supply and demand, high electricity price, and financial crisis in the accident were analyzed. Finally, this paper summarized the experience and lessons of power outages, and put forward relevant enlightenments to the construction of China's electricity market.

Key words: U.S. power outage, load-shed, electricity market, scarcity pricing
