电网系统防御方法、装置、计算机设备、介质和程序产品
By acquiring the attack data detection rate of each candidate topology, the target topology is determined, and its measurement data is used to determine whether the power grid system is under network attack. This solves the problem of poor defense effect of traditional power grid systems and achieves more accurate attack judgment and defense effect.

AI Technical Summary
Technical Problem
Traditional power grid system defense methods are ineffective against attacks using false data, and attackers can easily exploit system vulnerabilities to tamper with the data.
Method used
By acquiring the attack data detection rate of each candidate topology, the target topology is determined, and the actual and estimated quantity measurement data of the target topology are used to determine whether the power grid system is under network attack. The topology of the power grid system is then dynamically adjusted to improve the defense effect.
Benefits of technology
It improves the accuracy of the power grid system in detecting network attacks, prevents attackers from learning the system topology, and enhances the defense effectiveness of the power grid system.

Abstract
本申请涉及一种电网系统防御方法、装置、计算机设备、介质和程序产品。所述方法包括：根据各候选拓扑结构的模拟实际量测量数据和模拟攻击数据，获取各候选拓扑结构分别对应的攻击数据检测率，并根据各攻击数据检测率，从各候选拓扑结构中确定目标拓扑结构。进一步地，获取目标拓扑结构对应的目标实际量测量数据和目标估计量测量数据，并根据目标实际量测量数据和目标估计量测量数据判断电网系统是否受到网络攻击。本申请实施例一方面有利于发挥目标拓扑结构对电网系统的防御作用，使得电网系统对于网络攻击的判断更加精确，另一方面由于目标拓扑结构为变化的拓扑结构，使得攻击者无法获知电网系统的拓扑结构，从而有利于提高电网系统的防御效果。
