A Systems Approach to Information Technology (IT) Infrastructure Design for Utility Management Automation Systems

Iranian Journal of Electrical and Electronic Engineering 07/2006; 2:91-105.

ABSTRACT Almost all of electric utility companies are planning to improve their management automation system, in order to meet the changing requirements of new liberalized energy market and to benefit from the innovations in information and communication technology (ICT or IT). Architectural design of the utility management automation (UMA) systems for their IT-enabling requires proper selection of IT choices for UMA system, which leads to multi-criteria decision-makings (MCDM). In response to this need, this paper presents a model-based architectural design-decision methodology. The system design problem is formulated first; then, the proposed design method is introduced, and implemented to one of the UMA functions–feeder reconfiguration function (FRF)– for a test distribution system. The results of the implementation are depicted, and comparatively discussed. The paper is concluded by going beyond the results and fair generalization of the discussed results; finally, the future under-study or under-review works are declared.

    ABSTRACT: This paper presents an expert system for selecting a proper IT infrastructure for smart grid, based on a novel fuzzy approach to Tricotyledon Theory of System Design (Fuzzy-T3SD). The proposed Fuzzy-T3SD is a policy-driven decision making method that can change the result of the decision makings according to the utility's policy. The Fuzzy-T3SD is applied to the practical data of the Greater Tehran Electrical Distribution Company (GTEDC). Spread Spectrum (SS), Distribution Line Carrier (DLC) and Leased Line (LL) are regarded as alternatives for the IT infrastructure. The implemented results are examined by the developed policies scenarios.

    ABSTRACT: While the smart grid dream is likely to be revisited, we are witnessing a convergence of Information Technology (IT) with power system engineering. This convergence should be managed tactfully, to obtain a consistent architecture for the smart grid. Due to the complex nature of the both IT and power systems, a higher degree of complexity emerges through the smart grid. Therefore, selection of the right IT infrastructure for the smart grid is a complicated decision making problem. However, many of these decisions are made based on personal expertise, ad hoc methods and heuristic rules. They not only are highly suspected of not being optimal, but also are prone to serious mistakes. This mandates a consistent decision making method for the selection of the IT infrastructure in the smart grid. In this paper, Wymorian Tricotyledon Theory of Systems Design (T3SD) and Fuzzy Data Envelopment Analysis (FDEA), as a variation of Data Envelopment Analysis (DEA) and being capable of handling uncertainty, are employed as a decision supporting tool, to encompass the real world selection and decision issues which is presented as T3SD Fuzzy DEA method.

    ABSTRACT: this paper presents a novel expert system referred as Petri Net equipped Tricotyledon Theory of System Design (PN- T3SD) to select a proper IT infrastructure for smart grid. The proposed PN-T3SD is a policy-driven decision making method - combining the ideas from Petri nets and Wymorian T3SD- that can change the result of decision making according to the utility's policy. The PN-T3SD is applied to the practical data of the Greater Tehran Electrical Distribution Company (GTEDC). Three Alternatives of Spread Spectrum (SS), Distribution Line Carrier (DLC) and Leased Line (LL) are selected as proposed IT infrastructure. The implemented results are examined by developed policies scenarios.
