Designing of a simulator architecture for greener data center through knowledge transfer by partners in different sectors

In recent years, increasing demand for internet service providers, cloud services and the information and communications technologies, data centers (DCs) have become a very important place in the energy consumption industry. Furthermore, the energy consumed by the IT industry including DCs reached about 10% of the world's electricity generation. Therefore data centers have become a significant source of CO2 emissions and a crucial player in the electrical power system. In order to predict energy demand better and reduce energy consumption and CO2 emissions in specific national DCs, the GreenDC Project aims developing a decision support tool. This project was funded by EU through H2020 Marie Skłodowska-Curie. It is progressing by secondment activities that consist of knowledge transfer between academic and industrial partners. This paper aims to define and explain the architecture of its decision support tool, GreenDC DSS. The GreenDC DSS architecture composed of four interactional layers which are data layer, math model layer, business logic layer, and user interface layer. In this paper, the design of each layer has been described and the process of entire GreenDC DSS Tool has been examined with an example user scenario which is formed by considering the user requirements of data center managers. Also, it has been shown that a skeleton of the simulator gives optimum working strategies to data center manager

DSPFAP: Distribution Systems Power Flow Analysis Package Using Matlab Graphical User Interface (GUI)

WOS: 000274695000001This paper describes a software package whose purpose is to provide a tool to be used for load How analysis in Power System Analysis courses. The software package which is called Distribution Systems Power Flow Analysis Package (DSPFAP) uses the graphical user interface (GUI) capabilities of Matlab. The main advantage of the developed package is that the load flow analysis can be achieved in both transmission and distribution levels. The package facilitates different forward/backward sweep-based algorithms to be used for the distribution systems and conventional Newton - Raphson, Gauss-Seidel algorithms for the transmission system load flow analysis. In addition to that, effect of voltage dependent load models and effects of DGs on the distribution systems load flow solution car be investigated using the program. it is also possible to use conventional algorithms for distribution system load flow analysis in the package. The package can freely be downloaded from the website: http://www.gyte.edu.tr/Dosya/102/power/.

A tool for voltage stability and optimization (VS&OP) in radial distribution systems using matlab graphical user interface (GUI)

WOS: 000256638900003This paper describes a software package whose purpose is to provide a tool to be used for identifying the closeness of the each bus and the critical bus which is the most sensitive to the voltage collapse in radial distribution networks. The package also facilitates two optimization algorithms to be used for the optimal placement of Distributed Generation (DG) and shunt capacitors with their optimal size in distribution networks for power system studies. It uses the graphical user interface (GUI) capabilities of Matlab and is called voltage stability and optimization (VS&OP) Package. It is available at http://www.gyte.edu.tr/Dosya/102/power/ and can freely be downloaded. (C) 2008 Elsevier B.V. All rights reserved
