摘要
3060双碳目标将推进我国能源转型进程,新能源高渗透率为电网带来的不确定性与复杂性使其对日常运行时备用调节电源需求和应对极端自然灾害与人为攻击时的弹性需求增高,因而促使新型储能技术在电网快速规模化应用。本文讨论了在极端事件下,储能在弹性电网中的应用。首先,从新型储能装置的发展动态和对弹性需求的支撑出发,结合弹性电网概念内涵、衡量要素和极端事件特性,探讨了储能在弹性电网中的需求必要性和应用目标,提出了储能在极端事件下弹性承受和恢复两个阶段中的作用过程、作用机制和调节目标。其次,分析了广域布局储能的聚合容量与弹性电网承载能力之间的关系,研究了储能对灾后网架重构的影响,以及弹性指标评价框架等,提出了储能在弹性应用中的规划、调控、量化指标和市场机制制定等关键技术研究点。针对极端事件的应用需求、储能的运行性能与经济特性,提出了未来新型储能系统的适用典型场景。最后,对我国储能在弹性电网中的应用前景进行了展望。
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.
