A Tool for Voltage Stability & Optimization in Radial Distribution Systems Part I: Optimization Analysis

This paper describes a software package whose purpose is to provide a tool to be used for defining the optimal size and placement of Distributed Generation and shunt capacitors in distribution networks with three optimization algorithms for power system studies. The package also achieves to identify the closeness of the each bus and the critical bus which is the most sensitive to the voltage collapse in radial distribution networks. It uses the graphical user interface capabilities of MATLAB and called Voltage Stability & Optimization (VS&OP) Package. It is available at http://www.gyte.edu.tr/Dosya/102/power/ and can freely be downloaded. The paper is organized in two parts. This is the first part of the paper that deals with Optimization module.
