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...
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...
Smart grid expectations objectify the need for optimizing power distribution systems greater than ever. Distribution Automation (DA) is an integral part of the SG solution; however, disregarding human factors in the DA systems can make it more problematic than beneficial. As a consequence, Human-Automation Interaction (HAI) theories can be employed to optimize the DA systems in a human-centered manner...
Power grid cyber security is turning into a vital concern, while we are moving from the traditional power grid toward modern Smart Grid (SG). To achieve the smart grid objectives, development of Information Technology (IT) infrastructure and computer based automation is necessary. This development makes the smart grid more prone to the cyber attacks. This paper presents a cyber security strategy for...
Classical game theory is concerned with how rational players make decisions when they are faced with known payoffs. In the past decade, fuzzy logic has been widely used to manage uncertainties in games. In this paper, we employ fuzzy logic to determine the priority of a payoff to other payoffs. A new term is introduced to measure the preference of one payoff to others. By this means a fuzzy preference...
We address the automatic school timetabling problem and propose a solution based on co-evolution. A school timetable is a weekly schedule for all the teachers of the school and allocates class periods to teachers according to some constraints. Genetic algorithm has been previously used as a powerful tool for timetabling problems but the intrinsic complexity of these problems and the usually huge number...
The method of multiple heterogeneous ant colonies with information exchange (MHACIE) is presented in this paper with emphasis on the speed of finding the optimal solution and the corresponding computational complexity. The proposed method which is inspired by biology and psychology has a structure composed of several ant colonies. These colonies participate in solving problems in a concurrently manner...
