Extended vulnerability analysis framework
Challenge and objective
- Modern electric power systems are complex cyberphysical systems.
- The integration of traditional power and digital technologies result in interdependencies that need to be considered in risk analysis.
- The Vulnerability Framework previously developed for power systems is adapted and applied for a combined analysis of power system- and cybersecurity vulnerabilities on a realistic case
- An extended framework for combined power and ICT system vulnerability analysis, including dependencies and interdependencies.
- A case study demonstrating its application, with promising results, to support further use of the framework considering interdependencies and keeping the system perspective.
Impact for distribution system innovation
- Decision support for management of reliability of power supply affected by cybersecurity makes it possible to control vulnerability in complex cyberphysical systems.
