数据驱动的新型电力系统安全风险预警综述

Review of Data-driven Security Risk Early Warning Research of the New-type Power System

  • 摘要: 构建新能源占比逐渐提高的新型电力系统是落实“双碳”目标的重要举措,新能源发电的强不确定性和电力电子设备的弱抗扰性使得新型电力系统运行面临更大的安全风险。安全风险预警提前对电网未来的运行场景进行安全性分析,辨识不安全风险并为防控决策提供指导信息,是保障新型电力系统安全稳定运行的有效手段。为了提高安全风险预警的计算速度,数据驱动的安全风险预警方法得到了愈加关注。首先,梳理了新型电力系统的源-网-荷-储新特征,包括源侧大规模新能源发电接入、网侧特高压交直流紧密耦合、荷侧分布式新能源与新型负荷接入以及储能应用于系统的功率调节控制等。然后,阐述了新型电力系统存在的主要动态安全风险,并建立了新型电力系统的安全风险预警框架。接着,分别针对运行场景生成与缩减、预想事故筛选、安全风险评估和严重度分级这4个安全风险预警的主要环节,综述了国内外的相关研究工作。最后,结合新型电力系统的突出特点,分析了现有数据驱动的安全风险预警研究中存在的问题,并展望了未来的研究方向。

     

    Abstract: Constructing the new-type power system integrated with an increasing proportion of renewable generation is an important measure to achieve the goals of "carbon emission peak and carbon neutrality." The high uncertainty of renewable power and the weak immunity of power electronic equipment bring a bigger security risk to the operation of the new-type power system. Security risk early warning performs security analysis for future power system operating conditions (OCs), identifying the security risk and guiding control decision-making. It is an effective technique to safeguard the secure and stable operation of the new-type power system. To improve the computing speed of security risk early warning, data-driven security risk early warning methods draw more attention. First, the new features of the source side, network side, load side, and energy storage of the new-type power system are elaborated, which include the integration of large-scale renewable generation, the interaction of ultra-high-voltage AC and DC systems, the integration of distributed renewable generation and new-type loads, and the application of energy storage for power regulation and control. Then, the main dynamic security risk of the new-type power system is introduced, and the security risk early warning framework is formulated. Next, the domestic and foreign research work of four main parts is reviewed, which include the generation and reduction of OCs, contingency screening, security risk assessment, and insecure severity grading. Finally, with the characteristics of the new-type power system considered, the problems in existing data-driven security risk early warning research work are analyzed, and future research directions are prospected.
