Abstract：The high proportion of renewable energy integration and multi-energy synergy demands within new power systems impose higher requirements on energy storage technologies.Solid electric thermal storage technology,owing to its advantages of clean-low-carbon,flexibility,efficiency,security,reliability high thermal efficiency and automation,is increasingly becoming a crucial means to enhance the regulation capacity of new power systems and promote renewable energy accommodation.Based on the characteristics and challenges of new power systems,this paper analyzes the core architecture and key technologies of SETS.Combining case studies in scenarios such as peak shaving and valley filling,renewable energy integration,distributed energy systems and integrated energy system,it explores the application po-tential of solid electric thermal storage technology in emerging models like microgrids and virtual power plants.Within new power systems,the application of key SETS technologies-including high-efficiency thermal storage materials,struc-tural control and system integration,and optimization of driving control strategies—improves the thermodynamic cycle process.The application demonstrates economic viability and development prospects.Future efforts should focus on dig-ital integration,breakthroughs in long-duration thermal storage technologies,the construction of innovative mechanisms involving blockchain and market design to propel the large-scale application of SETS technology in new power systems.
