摘　　要：“双碳”目标下新型电力系统面临交直流系统故障耦合传播、频率与电压稳定风险上升等新的安全问题,引入储能参与安全调控的研究已逐渐成为热点。为了更有效地挖掘储能参与安全调控的能力,有必要对储能为电力系统提供安全支撑的场景、理论与技术方法进行梳理总结,并在此基础上探讨后续需要重点关注的问题及研究思路。从储能对电力系统静态安全、动态安全、交直流混联电力系统安全、主动安全技术、辅助服务市场5个方面进行总结,涉及储能与电网可靠性、储能与频率稳定性、储能与电压稳定性、储能与输电堵塞、储能与直流闭锁连锁跳闸防控等方面的研究进展,指出了关注储能备用荷电状态(state of charge,SOC)、储能与其他调控资源之间多时间尺度耦合研究的重要性,以及完善储能参与系统紧急安全调控服务市场机制的必要性,对促进储能参与新型电力系统安全调控的研究具有一定参考意义。In achieving"carbon neutrality,"the new power system faces a range of security challenges.These include the emergence of coupled faults in AC and DC systems,as well as an increased risk to frequency and voltage stability.Consequently,there is a growing interest in integrating energy storage technology into security control measures.To better understand the role of energy storage in enhancing system security,it is essential to outline the relevant scenarios,theories,and technical approaches.This will provide critical support to the power system while identifying key areas of future research.This paper focuses on five key aspects:static and dynamic security of the power system,security considerations in AC/DC hybrid power systems,active security technologies,and the ancillary service market.These areas encompass the progress made in understanding the relationship between energy storage and grid reliability,frequency stability,voltage stability,transmission blockage,and DC blocking cascading trip prevention.The research highlights the significance of examining the state of charge(SOC)reserve capabilities of energy storage,investigating the multi-timescale coupling between energy storage and other regulating resources,and improving the market mechanisms to facilitate energy storage's participation in emergency security regulation services.These findings provide valuable insights for advancing the research on energy storage's role in enhancing security in the evolving power systems.
