DSPFAP: Distribution systems power flow analysis package using Matlab graphical user interface (GUI)

This paper describes a software package whose purpose is to provide a tool to be used for load flow 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 can 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/. © 2009 Wiley Periodicals, Inc.
