| 1 | Texas Electric Power Crisis of 2021 Warns of a New Blackout Mechanism显示文摘The Texas electric power crisis that occurred in February 2021 has drawn great attention internationally due to its severity and for not having been foreseen.In this rapid communication,we classify the 2021 Texas electric power crisis as an energy insufficiency-caused power crisis,which alerts of a new blackout mechanism.Different from capacity insufficiencycaused power crises in the past,the Texas electric power crisis of 2021 directly resulted from the long-duration extreme cold weather as well as fundamentally from the insufficiency of sustainable supply capability of energy.We begin this paper with a brief retrospect of the event and its consequences.Definitions of energy/capacity insufficiency-caused power crises are given,as well as an overview of the supply and demand during the event,based on realistic operation data.Quantitative simulations are then conducted to reveal the underlying reasons for the power crisis and reveal how to better prepare for the future.Finally,several insights and suggestions on handling the new mode of blackout in the future are proposed and discussed. | Guanglun Zhang Haiwang Zhong Zhenfei Tan Tong Cheng Qing Xia Chongqing Kang | 2022 | CSEE Journal of Power and Energy Systems2022，8，1： | 4 |
| 2 | Review of Learning-assisted Power System Optimization显示文摘With dramatic breakthroughs in recent years,machine learning is showing great potential to upgrade the toolbox for power system optimization.Understanding the strength and limitation of machine learning approaches is crucial to decide when and how to deploy them to boost the optimization performance.This paper pays special attention to the coordination between machine learning approaches and optimization models,and carefully evaluates how such data-driven analysis may improve the rule-based optimization.The typical references are selected and categorized into four groups:the boundary parameter improvement,the optimization option selection,the surrogate model,and the hybrid model.This taxonomy provides a novel perspective to elaborate the latest research progress and development.We further compare the design patterns of different categories,and discuss several key challenges and opportunities as well.Deep integration between machine learning approaches and optimization models is expected to become the most promising technical trend. | Guangchun Ruan Haiwang Zhong Guanglun Zhang Yiliu He Xuan Wang Tianjiao Pu | 2021 | CSEE Journal of Power and Energy Systems2021，7，2： | 2 |
