| 摘要: |
| 基于安全博弈理论，分析辨识综合能源系统安全运行的关键影响因素，将其作为安全防御的薄弱环节，制定防御策略并重点防护。构建综合能源系统防御者-攻击者-防御者3层零和主从博弈模型，攻击者以攻击系统的薄弱环节为策略期望最大化系统损失，防御者制定防护策略以增强系统的安全性；求解博弈模型的均衡解，得到的最小系统损失即为最佳防御策略；以某综合能源系统为例进行仿真分析，结果表明优先防护系统的薄弱环节可提升系统的安全可靠性，为分析综合能源系统的安全性提供参考。 |

| Abstract: |
| Based on the security game theory, the critical factors that impact the safe operation of an integrated energy system are analyzed and identified. These critical factors, which represent the weak link of security defense, are employed to produce defense strategies and are given priority to be protected. A three-layer zero-sum master-slave game model, i. e. the defender-attacker-defender model is formulated for the integrated energy system. The attacker utilizes the weak link of the attack system as strategies to maximize system loss, while the defender develops protection strategies to enhance system security. An equilibrium solution of the game model that represents the best defense strategy is obtained to minimize the system loss. Numerical results on an integrated energy system indicate that the proposed strategy improves the system safety and reliability by giving priority of the protection system to the weak links. The present work, hence, contributes to analyzing the safety of integrated energy systems. |
