- 基于时间的连锁故障动态模型已被公认为表示详细连锁信息的最全面的方法之一，并经常用于基准测试和验证。本文概述了电力系统连锁故障动态分析领域的进展，并概述了未来电网动态模拟的好处和挑战。的好处包括能够捕捉系统动态的时间特性，并提供定时信息，以促进停电缓解控制行动。连锁故障动态建模的最大障碍是计算负担，以及电力系统动态表示的广泛但通常不可用的数据要求。本文详细讨论了这些因素，并强调需要深入研究连锁故障的动态建模。此外，200节点和2000节点基准系统的动态级联仿真的案例研究提供了初步指导的关键参数的选择，以提高仿真效率。最后，交叉验证和比较对准稳态直流潮流模型进行比较，与各种指标进行比较。
—Time-based dynamic models of cascading failures have been recognized as one of the most comprehensive methods of representing detailed cascading information and are often used for benchmarking and validation. This paper provides an overview of the progress in the field of dynamic analysis of cascading failures in power systems and outlines the benefits and challenges of dynamic simulations in future grids. The benefits include the ability to capture temporal characteristics of system dynamics and provide timing information to facilitate control actions for blackout mitigation. The greatest barriers to dynamic modelling of cascading failures are the computational burden, and the extensive but often unavailable data requirements for dynamic representation of a power system. These factors are discussed in detail in this paper and the need for in-depth research into dynamic modelling of cascading failures is highlighted. Furthermore, case studies of dynamic cascading simulation of 200-bus and 2000-bus benchmark systems provide initial guidance for the selection of critical parameters to enhance simulation efficiency. Finally, cross-validation and comparison against a quasi-steady state DC power flow model is performed, with various metrics compared.
