As the use of micro grids increasing rapidly, it becomes necessary to analyze them for different operating and loading conditions as large power systems. At the outset, a MG is designed and simulated under MATLAB / Simulink platform. Normal operation data collected and stored. Then, different loading scenarios performed, operational data collected and stored to use for proposed method. Intelligent systems are used to process these data and also for training. After training a fully different scenario is created and the effectiveness of the proposed method is verified through simulation study. 2015-01-01T00:00:00Z http://dspace.beu.edu.tr:8080/xmlui/handle/123456789/13784 p-Summable sequence spaces with inner products Konca, Şükran; Idris, Mochammad; Gunawan, Hendra 2015-01-01T00:00:00Z http://dspace.beu.edu.tr:8080/xmlui/handle/123456789/13783 The Role of Energy Management in Microgrids With Hybrid Power Generation System Kocaman, Behçet; Abut, Nurettin Nowadays, consumption of energy is gradually increasing, the conscious for protecting environment is improving and liberalization in energy market is proceeding. Furthermore, the distribution of traditional energy sources is not homogeneous. These reasons are increasing interest to create policies for benefiting from renewable sources better by developing newer technology and to fuel cell based alternative distributed generation systems. Energy generation systems like wind, photovoltaic (PV), micro hydroelectric are the promising and the most important renewable energy technologies. Moreover, fuel cell based systems will indicate a great potential for future applications of distributed generation because of their quick developing technology, high productivity, pollutant gases with no or low emission and their elastic structures. In this study, energy management of a hybrid microgrid that was renewable energy based (wind, photovoltaic, micro hydroelectric) was provided by a computer program reformed in Microsoft C Sharp(C#) programming language in order to supply electric energy to small locations like holiday camps which were far away from energy distributing systems and other locations. It was observed that demanded energy was met by the data taken from generation sources thanks to this developed program. The importance of the energy management was explained by analyzing one year results via graphics. 2015-01-01T00:00:00Z http://dspace.beu.edu.tr:8080/xmlui/handle/123456789/13782 On Graphs of Dualities of Bipartite Posets Topal, Selçuk In this paper we introduce some new graphs obtained from bipartite posets. We show that lower-minimal graph of a bipartite poset is isomorphic to upper-maximal graph of dual of the poset by using set representations of the posets by using set representations of the posets. 2015-01-01T00:00:00Z
