摘要:

2020年8月14日和15日,美国加利福尼亚州(简称加州)电网出现了连续2 d切负荷运行的限电事故。在综合考虑加州电力系统高渗透率可再生能源和独特的市场机制设计的基础上,文中围绕导致加州限电的原因及多区域电力市场机制在限电过程中所发挥的作用这2个主题进行分析。基于此,文中首先结合实际市场运行数据,着重从可再生能源与净负荷和外受电量2个方面对其在本次加州限电事故的影响进行量化分析。其次,聚焦于加州及其周边地区正在推行的区域电力交易机制,对美国西部能量不平衡市场(WEIM)机制的运行方式与实施逻辑进行了深入剖析,分析并评估了美国WEIM机制对此次限电事故的影响程度。最后,总结讨论本次限电事故的经验与教训,并结合中国电力市场建设的国情与进展,对中国电力市场未来的区域融合、机制协同与建设路径提出了相关建议。

Abstract:

On August 14th and 15th, 2020, the power system experienced two consecutive days’ load shedding in the accident of electricity restriction in California, USA. On the basis of comprehensively considering the high-penetration renewable energy and the unique market mechanism design of the California Electric Power System, this paper analyzes two topics which are the causes of the process of electricity restriction in California and the role of regional market mechanism in the electricity restriction. Based on this, firstly, combined with actual market operation data, this paper mainly focuses on the quantitative analysis of the influence of two aspects: renewable energy with net load and imported electricity in the accident of electricity restriction in California, USA. Secondly, focusing on the regional power trading mechanism that is being promoted in California and its surrounding areas, an in-depth analysis of the operation mode and implementation logic of the mechanism of western energy imbalanced market (WEIM) is carried out. The impact of the mechanism of WEIM on the accident of electricity restriction is analyzed and evaluated. Finally, after summarizing and discussing the experience and lessons of the accident of electricity restriction, and combining with the conditions and progress of Chinese power market construction, relative suggestions are made for the future regional collaboration, mechanism coordination and construction path of Chinese electricity market.
