Modern power systems become more vulnerable to cyber threats due to their growing interconnectivity, interdependence, andcomplexity. Widespreaddeployment of distributed energy resources (dERs) further expands the threat landscape to the grid edge, where fewer cybersecurity protections exist. In this article, a systematic cyber-physical events demonstration, enabled by an integratedtransmission, distribution, andcommunication co-simulation framework, is performed. It analyzes cyber risks to power grid under dER-enabled automatic generation control from different angles. Unlike existing works, the simulation captures millisecond-to-minutes frequency and voltage transientdynamics at a cross-region system scale.
