信息-物理电力系统层:分类、表征和相互作用

Cyber-Physical Power System Layers: Classification, Characterization, and Interactions

Michael Abdelmalak, Narayan Bhusal, Mukesh Gautam, Mohammed Ben-Idris

摘要:

本文提出了一种识别信息物理电力系统(CPPS)的层和子层并描述其相互作用和内部作用的策略。物理层通常由电网和保护设备组成,而网络层由通信、计算和控制组件组成。将网络层的组件组合在一个层中会使建模内部动作的过程复杂化,因为每个组件都有不同的故障模式。另一方面,将网络层划分为大量子层可能不必要地增加系统状态的数量并增加计算负担。在本文中,我们分类系统层的基础上,他们共同的,耦合和共享的功能。此外,分类层之间的相互作用被识别,特征化,并基于它们对系统的影响进行聚类。此外,基于每个层的整体功能和其组件的类型,层内的动作的特点。本文提出的系统层综合分类策略及其相互作用和内部作用的表征有助于实现CPPS中状态转换、故障和攻击传播的准确和详细建模的目标,可用于各种可靠性评估研究。

英文摘要:

This paper provides a strategy to identify layers and sub-layers of cyber-physical power systems (CPPS) and characterize their inter- and intra-actions. The physical layer usually consists of the power grid and protection devices whereas the cyber layer consists of communication, and computation and control components. Combining components of the cyber layer in one layer complicates the process of modeling intra-actions because each component has different failure modes. On the other hand, dividing the cyber layers into a large number of sub-layers may unnecessarily increase the number of system states and increase the computational burden. In this paper, we classify system layers based on their common, coupled, and shared functions. Also, interactions between the classified layers are identified, characterized, and clustered based on their impact on the system. Furthermore, based on the overall function of each layer and types of its components, intra-actions within layers are characterized. The strategies developed in this paper for comprehensive classification of system layers and characterization of their inter- and intra-actions contribute toward the goal of accurate and detailed modeling of state transition and failure and attack propagation in CPPS, which can be used for various reliability assessment studies.
