Model to quantify digital risks for power grids integrating electrical system and cyber data models Modern substation integrated systems trend to increase the level of power system automation and remote accessibility, to deliver information to a wide range of users in near real time and also allow to control number of tasks that streamline operations and perfomance [1]. This drastic increase in sophistication of the automation and hidden interconnections (eg. to the Internet), is exposing the electric power industry to a growing risk of electronic intrusions. As seen today, every month there are reports of threats and attacks from hackers, disgruntled employees, and terrorists attempting to breach and/or corrupt sensitive control systems of utilities. However, many defensive techniques and practices have been used to reduce the chances of cyber attack and electronic intrusions [2]. This paper analyzes early and potentially mature models using the Real Time Digital Simulator (RTDS) and will surface the access points/control levers vulnerable to cyber intrusions, that include timely mitigations to limit their impacts.
