Resilience of Distributed Microgrid Control Systems to ICT Faults

Recent years a growing deployment of distributed generation (DG) in low voltage power grids is seen, and the amount of DG is expected to increase further in the near future. Distribution grids are however not designed to contain generators. Furthermore, no coordinated control for these generators exists and they provide little or no ancillary services. Therefore control strategies have been designed based on inexpensive ICT equipment and public communication networks. One such agent based control system is introduced in this paper. Also, several scenarios are simulated with ICT-fault injections to assess the systems’ resilience to these faults. After discussing the specific scenarios, the root causes of most limitations and vulnerabilities in generalized open, unbounded and distributed control systems are pointed out.
