The deep integration of computing, communication, and information technologies not only improves the operation level of the power grid, but also brings the threat of cyber-attacks on the power grid. This article studies power communication network topology planning problem considering both the normal operation level and the ability to against cyber-attacks from the perspective of information transmission reachability. First, by analyzing the game relationship between ensuring the normal operation level and defending against cyber-attacks, a framework of power communication network topology planning based on game theory is proposed. In this framework, the traditional planner tries to maximize the information transmission reachability of normal operation, while the anti-cyber-attack planner wants to minimize the information transmission reachability of cyber-attacks. Second, considering whether there are uncertainties in the planning, a deterministic topology planning model is proposed for the traditional planner, and an uncertainty topology planning model is proposed for the anti-cyber-attack planner. Third, considering the competition between the two planners, an improved particle swarm algorithm is introduced to solve the models. Finally, a standard example and a practical power communication network are used to verify the correction and effectiveness of the method.

基于信息传输可达性的网络攻击电力通信网络规划研究

计算、通信、信息技术的深度融合，不仅提高了电网的运行水平，也给电网带来了网络攻击的威胁。本文从信息传输可达性的角度研究电力通信网络拓扑规划问题，兼顾正常运行水平和抵御网络攻击的能力。首先，通过分析保障正常运行水平与防御网络攻击之间的博弈关系，提出了基于博弈论的电力通信网络拓扑规划框架。在这个框架下，传统的规划器试图最大化正常运行的信息传输可达性，而反网络攻击规划者希望最小化网络攻击的信息传输可达性。其次，考虑规划中是否存在不确定性，针对传统规划器提出确定性拓扑规划模型，针对抗网络攻击规划器提出不确定性拓扑规划模型。第三，考虑到两个规划者之间的竞争，引入了改进的粒子群算法来求解模型。最后，通过一个标准实例和一个实际的电力通信网络来验证该方法的正确性和有效性。提出了一种针对网络攻击规划器的不确定性拓扑规划模型。第三，考虑到两个规划者之间的竞争，引入了改进的粒子群算法来求解模型。最后，通过一个标准实例和一个实际的电力通信网络来验证该方法的正确性和有效性。提出了一种针对网络攻击规划器的不确定性拓扑规划模型。第三，考虑到两个规划者之间的竞争，引入了改进的粒子群算法来求解模型。最后，通过一个标准实例和一个实际的电力通信网络来验证该方法的正确性和有效性。
