摘要:

在电力电子系统(PES)中,针对数据可用性的攻击,如延迟攻击、数据丢失和时间同步攻击(TSAs),持续对通信网络和控制系统性能构成重大威胁。按照通信工程的常规规范,PES仍然依赖时间同步采样,这种采样方式将每一条接收到的消息都视为同等重要。在本文中,我们超越事件触发采样/估计,将语义原理集成到每个分布式能源资源(DER)的采样过程中,这不仅通过从内部控制层动态重构新信号来补偿延迟的通信信号,而且还利用关键语义要求来评估重构阶段,即新鲜度、相关性和优先级,以获得良好的动态性能。因此,内部控制回路动态的事件驱动采样所提供的稀疏性在PES中转化为语义。所提出的方案已在改进的IEEE 37节点交流配电系统上进行了广泛测试和验证,在OPAL-RT环境中多种运行条件和噪声环境下,确立了其鲁棒性、无模型设计能力以及对动态网络图拓扑的自适应行为。

英文摘要:

In power electronic systems (PES), attacks on data availability such as latency attacks, data dropouts, and time-synchronization attacks (TSAs) continue to pose significant threats to both the communication network and the control system performance. As per the conventional norms of communication engineering, PES still rely on time synchronized sampling, which translates every received message with equal importance. In this paper, we go beyond event-triggered sampling/estimation to integrate semantic principles into the sampling process for each distributed energy resource (DER), which not only compensates for delayed communicated signals by reconstruction of a new signal from the inner control layer dynamics, but also evaluates the reconstruction stage using key semantic requirements, namely Freshness, Relevance and Priority for good dynamic performance. As a result, the sparsity provided by event-driven sampling of internal control loop dynamics translates as semantics in PES. The proposed scheme has been extensively tested and validated on a modified IEEE 37-bus AC distribution system, under many operating conditions and noisy environment in OPAL-RT environment to establish its robustness, model-free design ability and adaptive behavior to dynamic cyber graph topologies.
