    A tool for voltage stability and optimization (VS&OP) in radial distribution systems using matlab graphical user interface (GUI)
    (ELSEVIER SCIENCE BV, 2008) Gozel, T.; Eminoglu, U.; Hocaoglu, M. H.
    This 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.

    Distribution Systems Forward/Backward Sweep-based Power Flow Algorithms: A Review and Comparison Study
    (TAYLOR & FRANCIS INC, 2009) Eminoglu, U.; Hocaoglu, M. H.
    Because of different characteristic features of distribution networks, such as radial structure and high R/X ratio, distribution system load flow analysis differs significantly from transmission systems. Accordingly, a number of methods that are specially designed for the solution of the power flow problem in radial distribution systems are found in the literature. Most of the developed methods are based on the forward/backward sweep processes for the solution of the ladder networks. In this article, various distribution system load flow algorithms, based on the forward/backward sweeps, are reviewed, and their convergence ability is quantitatively evaluated for different loading conditions, R/X ratios, and sub-station voltage levels. Moreover, the effects of static load modeling on the convergence characteristics of algorithms are also investigated.

    DSPFAP: Distribution Systems Power Flow Analysis Package Using Matlab Graphical User Interface (GUI)
    (WILEY-BLACKWELL, 2010) Eminoglu, U.; Gozel, T.; Hocaoglu, M. H.
    This 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/.
