Abstract

The sun is the origin of space weather that is driven by violent activities of the sun. The disastrous space weather greatly influences technology systems on the ground. Among the influenced technology systems, the influence on power grids is the most severe, and the larger the power grid scale is, the more vulnerable it is. In this paper, the basic concept of space weather and its main impact are discussed and the present situation of the research in this field home and abroad is reviewed. On the basis of analyzing the accidents impacted by space weather home and abroad, the scientific issues, which must be researched and solved to cope with disastrous space weather for very large-scale power grids in China, are proposed. Studying these issues will be favorable to improve the international academic standing of China in the field of space weather and its impact, and can provide theoretical and technical foundation to ensure secure and reliable operation of large-scale power grid in China.
