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: Intelligent control and automation is associated with expert systems; especially, when it needs to human expertise. Earlier we introduced a framework for implementation of adaptive autonomy (AA) in human-automation interaction systems, followed by a data-fusion-equipped expert system to realize that. This paper uses fuzzy sets concept to realize the AA expert system, in a real automation application. The presented adaptive autonomy fuzzy expert system (AAFES) determines the Level of Automation (LOA), adapting it to the changing Performance Shaping Factors (PSF) of automation system. The paper includes design methodology and implementation results for AAFES, and discussion on results. Results show that AAFES yields proper LOAs, even in the new contingency situations. This is caused by AAFES's higher intelligence than the crisp (binary) one. Moreover, since AAFES deals with fuzzy linguistic PSFs, it more realistically represents the experts' opinion.

    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.
