In this paper, planning of a grid-connected smart micro-power system is investigated. At first, its Advanced Metering Infrastructure (AMI) is designed to record, process and communicate the micro-grid energy, electrical data (e.g., active and reactive power flow data, voltage, frequency etc.), wind speed, solar radiation and so on, which are sent to the Data-Processing and Management center (DPMc)...
The complexity of humans and automation interaction in Smart Grid, as the future of power system, calls for embedding a level of intelligence in the system. Adaptive Autonomy (AA) theory is employed to manage high level complexity of the Human-Automation Interaction (HAI) system. The fuzzy expert system with Gradient Descent Algorithm (AAFGDES) is a data-driven approach applied to determine the Level...
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...
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...
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...
