Towards a distributed intelligent ICT architecture for the smart grid

Abstract

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.I.

Distributed Semantic Architecture for Smart Grids

“…The major domain authorities (EPRI and IEC, the International Electro-technical Commission) have backed the development of a central smart grid standard, the so-called CIM (Common Information Model, [18]) and, then, defined its OWL model, laying the foundations for many research projects that have extended the CIM to include related electric protocols [19], combined the CIM ontology with other protocols' ontologies to achieve interoperability [20], etc. The EPRI has issued a number of recommendations to carry out this harmonisation, which could be implemented through OWL language assertions, once both data models are converted to its semantic form, thus also allowing us to perform automatic reasoning and inference processes [21][22][23].…”

“…In the aforementioned ENERGOS project [14], the anchor for addressing this challenge is an intelligent node called PGDIN (Power Grid Distributed Intelligence Node) [21]. A PGDIN encapsulates a variety of powerful technologies for event and data processing of the grid, in an intelligent and autonomous way.…”

“…The aforementioned OWL-DL ontology enables the PGDIN to deal with a unified domain that combines all concerning standards. In order to be able to cope with all the requirements discussed before, the PGDIN is composed of the following modules and technology interfaces (the rationale of choosing the technologies presented next has been discussed and justified in [16,[21][22][23]), as shown in Figure 1.…”

“…There are several approaches and alternatives to implement agents following the FIPA specifications, and the PGDIN implements the JADE bundle (eventually, depending on the final hardware platform and its performance, some PGDINs may alternatively implement a light-weight agent platform such as LEAP). Further information on the PGDIN design can be found in [21]. This technology is implemented by means of the components: JADE and OSGi.…”

A Decentralized and Proactive Architecture based on the Cyber Physical System Paradigm for Smart Transmission Grids Modelling, Monitoring and Control

“…In this context, the rapid development of the Information and Communication Technologies (ICT) has opened the door towards feasible and cost-effective control and monitoring paradigms, allowing more extensive intra/interutility information exchange, diffusion, and open access to a wide range of real time information [6]. Consequently, they could play a strategic role in supporting the deployment of advanced information services for CPPS as confirmed by various research studies recently published in the literature [7,8].…”
