Description

Microgrids are becoming a cornerstone of power distributions systems that will facilitate the realization of a carbon-neutral electric power systems. Alongside their flexibility to be operated in both grid-connected and autonomous modes, they also provide natural interfaces with many types of RES and ESSs and good compliance with consumer electronics. Moreover, microgrids can be grid-interactive by providing grid supportive functions such as frequency response and, regulation, reactive power support and voltage regulation, etc. All these facts lead to more and more deployment of microgrids in transmission and distribution levels. Furthermore, with proliferation of communication technologies, microgrids are evolving into cyber-physical systems (CPS) that use sophisticated software-based networked control. This increased sophistication imposes numerous new challenges involving coordination, operation philosophy and vulnerability to cyber-attacks.

Cyber-attacks can be designed in many ways: (a) sensor infiltration, (b) communication infringement. Even though several hard-bound secure protocols are designed to ensure the authenticity of the actual signal, the attackers usually target the control layer as an easy target. Hence, this course aims to focus: (a) identifying the vulnerable access points in microgrid controllers, (b) introduce the most prominent cyber-attacks, (c) detection of cyber-attacks in in real-time, (d) removal of these attack elements and ensuring stability/preventing system shutdown, (e) design of resilient controllers for microgrids, which heals by itself despite any cyber intrusion attempts. All models will be provided to attendees and experimental lab demonstration is expected as well along with discussion on future research ideas.
