Cyberattacks on the energy systems, the backbone of modern society, can cause nationwide disruptions, making them an attractive target for state-sponsored threat actors. This Engineering Research Initiation (ERI) project will analyze the impacts of communication-based cyberattacks targeting the electric grid infrastructure and provide solutions to enhance the security and resilience of the energy sector. The project will bring transformative changes enabling the integrated simulation of both the electric and communication systems. Given the interdependence of these two systems, analyzing them in a unified framework is essential to uncover vulnerabilities that may remain obscured when examined independently. This will be achieved by examining the impact of communication-based cyberattacks on power systems, identifying weaknesses, and formulating strategies for the optimal deployment of secure communication devices. The intellectual merit of the project includes the joint evaluation of the electric and communication systems to identify cybersecurity risks that could compromise grid stability. The resulting insights will strengthen power system design, enhance operational resilience, and thereby contribute to national efforts to improve the security of the critical energy infrastructure. The broader impacts encompass the development of tools that will support the design of cyber-secure power systems, where communication devices play a pivotal role. The research outcomes will enr
