新型储能技术在弹性电网中的应用与展望

The '3060 double carbon' goal promotes energy transformation in China. The uncertainty and complexity of the power system associated with the high penetration of renewable energy would increase the demands for regulated power supplies and resilience response capability to accommodate extreme natural disasters and man-made attacks, which facilitates the large-scale application of new energy storage technology in the resilient power system. This paper discusses, in detail, the application of energy storage in resilient power systems under extreme events. Firstly, based on the development trend of energy storage, this study combines the concept connotation, the measurement elements of resilient power systems, and the characteristics of extreme events to explore the necessity of the demand and the application target of energy storage in resilient power systems. The function process, mechanism, and regulation target of energy storage are proposed for the two stages of resilient bearing and recovery under extreme events. Secondly, the application characteristics and mechanism are analyzed for energy storage in the bearing and recovery stages of the resilient power system. Thirdly, this work analyzes the relationship between the aggregate capacities of the decentralized energy storage and the bearing capacities of the resilient power system, and the impact of energy storage on post-disaster network reconfigurations is also assessed. Improvements in the resilient index evaluation framework and the electricity market mechanism formulation under the increasing energy storage capacity are examined in this work. Key technical points are proposed, such as planning, regulation, and quantitative indicators for the resilient application of energy storage. Then, this study proposes the typical scenarios considering the application requirements for extreme events, energy storage performance, and economy. Finally, the perspective of the application of energy storage for resilient power systems in China is discussed.
