The future communication infrastructure in distribution grids might lack, for economic reasons, bandwidth for running all possible smart grid services. This can create communication congestions which can lead to delayed critical messages in the power system possibly aﬀect the power system stability. Prioritizing smart grid services may maintain the core functionality of the power system in high traﬃc situations by neglecting low-prioritized services. The number of neglected services can vary depending on the system situation. The prioritization of services considering QoS, such as latency, can be transformed into a dynamic constraint satisfaction problem. Constraint satisﬁability may be positively inﬂuenced by virtualized services that are ﬂexibly moved to servers in order to relieve or avoid the congested communication areas. This PhD-project focuses on the combination of the dynamic constraint hierarchies and virtualization of smart grid services to contribute to the operation of distribution grids.
