- ICT-enabled smart grid devices, potentially introduce new cyber vulnerabilities that weaken the resilience of the electric grid. Using real and simulated PV inverters, this work demonstrates how cyber-attacks on IEC 61850 communications to field devices can force an unstable state, causing voltage oscillations or overvoltage situations in a distribution grid. An automated resilience mechanism is therefore presented, combining intrusion detection and decentralised resilient controllers, which is demonstrated to assure stable operation of an energy system by counteracting cyber-attacks targeting embedded PV inverters.

- In the domain of energy automation, where a massive number of software-based IoT services interact with a complex dynamic system, processes for software installation and software update become more important and more complex. These processes have to ensure that the dependencies on all layers are fulfilled, including dependencies arising due to the energy system controlled by IT components being a hidden communication channel between these components. In addition, the processes have to be resilient against faults in and attacks to both the energy grid and the communication network. The ERA-Net funded project LarGo! aims at developing and testing processes for the large scale rollout of software applications in the power grid domain as well as the user domain. This article describes a work in progress and the project's roadmap to solve the technical issues. It investigates the problems that arise from the interlocking of the two networks - the power grid and the communication network. Based on this analysis a first set of requirements for a rollout process in such a Smart Grid is derived and the chosen approach to verify the resilience of the developed processes under research is described.
