Resilient Access to Heterogeneous Measurement Data for Grid Observability

The ability to fuse data from heterogeneous sources (such as Smart Meters etc.) in the low-voltage grid highly depends on the communication and data management infrastructure that allows an exchange of information between different grid assets. Failure or any attempt to attack this data fusion solution can lead to inefficient grid operation and in worst case even blackouts. Therefore, this paper describes methodologies to cope with threats and faults in a low-voltage grid scenario to provide resilient access to the heterogeneous measurement data.
