Towards a distributed intelligent ICT architecture for the smart grid

Given the challenges posed by the smart grid paradigm, we propose hereby a distributed intelligent ICT architecture, which is built upon a basic brick named PGDIN (Power Grid Distributed Inteligence Node) integrating a DDS middleware, an ESP/CEP engine, a distributed cache, and an OWL unified model for power standards. A case study dealing with substation monitor and control is also introduced.
