The globe is currently facing a slew of issues, including resource scarcity, climate change, pollution, and energy poverty, all of which are founded in humanity's significant reliance on and large-scale usage of fossil fuels. Addressing these issues is a critical undertaking for achieving long-term growth. The Global Energy Interconnection (GEI) is a contemporary energy system that is clean energy dominant, electricity focused, networked, and shared. The global energy interconnection (GEI) is the greatest manmade physical system to be developed in the near future, with intimate connectivity between power and information networks. Information system risks will have a significant influence on power system security. This work proposes a risk assessment model for linked physical-information systems based on a set of information system risk characteristics. A method for assessing risk is described. The usefulness of the suggested assessment model and evaluation approach is demonstrated by simulation results of a typical power system and information networks.
