A coordinated approach for power system security to support smart grid transition

The power and energy system is facing landscape change in order to meet the net-zero target by 2050. The convergence of the information technology (IT) and operational technology (OT) in power and energy systems brings numerous advantages including improved efficiency and reliability. Yet, the convergence of IT and OT systems results in increased risk of cybersecurity breaches. This is mainly due to the distinct features of the security practices in IT and OT domains. In this project, we take a holistic approach to cybersecurity of energy systems with IT/OT convergence by integrating security measures both in IT and OT domains. In order to verify the accuracy and effectiveness of the proposed holistic approach, we develop an intrusion detection system for transmission line protective relays which considers both IT and OT domains. In the IT domain, the security measures focus on the features of the communication packets to identify potential cyberattacks. In the OT domain, the security measures focus on the characteristics of the transmission line current and voltage measurements to identify potential cyberattacks.

Applications will be considered on an ongoing basis. Due to funding restrictions, the position must be awarded by 31 July 2021 (for a project start date of 1 October 2021). Potential applicants are strongly encouraged to contact the supervisors for an informal discussion before making a formal application. We also advise that you apply at the earliest opportunity as the application and selection process may close early, should a suitable candidate be appointed.
