Next generation of energy systems, being dependant on
Renewable Energy Resources (RES) and Distributed Generation
(DG), will typically be based on flexible virtual cells of cells of
balanced power consumption – generation, that is microgrids,
rather than present day vertical hierarchical grid systems.
Furthermore, the supporting information infrastructure and nonlinear
dependencies will pose new dependability challenges to
the systems involved. As a consequence, we have to decouple
present day proprietary hierarchical SCADA systems into sets of
services that allow for horizontal as well as vertical integration
supporting operations and business models of future virtual
utilities. The virtual utilities are integrating two critical
infrastructures; power grids and cyber networks. To allow for
this flexibility and assuring dependability we argue that the
underlying infrastructures should be modelled as Service
Oriented Architectures (SOA). We propose in this paper a
methodology towards ensuring quality of service in virtual
utilities based on microgrids.
