中文摘要

固态变压器(SST)依赖闭环控制和测量反馈。由于物理耦合,SST网络易受网络攻击扩散及其对系统稳定性影响的威胁。特别是AC-AC型SST高度依赖控制同步,任何波动均可能导致系统失稳。

English Abstract

Solid-state transformers (SSTs) rely on adequately functioning the closed-loop control and measurement feedback variables. Due to physical coupling, a network of SSTs is vulnerable to the diffusion of cyberattacks and their impact on the system's stability. AC–AC-type SSTs, in particular, rely heavily on control synchronization, and any fluctuations can quickly lead to system instability. In this ...
