Abstract: A quantum-key distributed (QKD)-enabled communication architecture it devises for networked microgrids (NMGs). A real-time QKD-enabled NMGs testbed built in an RTDS environment, and a novel two-level key pool sharing (TLKPS) strategy it designs to improve the system resilience against cyberattacks. In the QKD-based microgrid testbed design there is used a real-time power system simulator, i.e., RTDS, including the QKD modeling, hardware connection, communication network design, and QKD integration. By integrating QKD features into a real-time microgrid simulator, this testbed offers a flexible and programmable testing environment for evaluating the performance of QKD-enabled microgrids under a variety of scenarios.
