随着国际形势日趋严峻复杂以及智能化和信息化技术在电力系统中的广泛应用，电力系统已成为网络攻击的重点目标，其网络安全的重要性愈发突显。为了构建研究电力网络安全风险演变的利器，支撑网络安全风险预测指挥工作，提出了一种面向电力网络安全演变的兵棋推演方法，通过策略层面的兵棋仿真推演，构建了基于可组合性和最小操作单元理念的推演框架，实现了大规模电力网络安全场景建模并提高了仿真效率，同时能够高效地识别网络中的潜在风险。通过实验验证，该方法在大规模电力信息网络安全推演中表现出优异的性能，能够为电力网络安全风险演变研究、网络安全策略优化和网络安全指挥作战提供强有力的支撑。

As the international situation becomes increasingly complex and the widespread adoption of intelligent and information technologies in power systems continues, power systems have emerged as prime targets for cyber-attacks, highlighting the critical importance of cybersecurity. To provide a powerful tool for studying the evolution of security risks in power network and support cyber risk prediction and command work, a wargaming-based method is proposed for modeling the evolution of power network security. A deduction framework based on the concepts of composability and minimal operation units is constructed through strategic-level wargaming simulations to achieve large-scale power network security scenario modeling and improve simulation efficiency, while effectively identifying potential risks in the network. Experimental validation demonstrates that the proposed method exhibits superior performance in large-scale power information network security wargaming, providing robust support for research on the evolution of power network security risks, optimization of cybersecurity strategies, and command operations in network security.
