Understanding Interdependencies in Cyber-Physical Power Systems - A Review

The electric power system is a critical infrastructure for the well-being of modern society. Therefore, its efficient and reliable operation is of paramount importance. Information and communication technology (ICT) has increasingly been integrated into the electric power system to assist system operators in making more informed decisions, enabling the efficiency and reliability of the power system to be properly managed. However, it has been found that interdependency issues can arise, i.e. problems in the ICT system can cause problems in the power system, and vice versa. This paper will discuss ICT and power system interdependencies and the state-of-art in modelling cyber-physical power systems (CPPS).
