A Petri Net-T3SD policy driven method for IT infrastructure selection in smart grid

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.
