Optimal Distribution Substations Placement using Genetic Algorithm

29 Jan 2006 (Updated 30 Jan 2006)

Finds the optimal location and capacity of distribution substations

File Information
Description	This program uses an Excel data file "DATA.xls" as an input to the program. the input file consists these worksheets: 1.input load data (active power of each load block and their X-Y cooedinates 2. present transformers and their capacities in kVA 3. candidate points for new transformers 4. transformers Loading Factor and design Power Factor 4. types of transformers usable in the netwok. this program searches for the best allignment and configuration for distribution substations. the optimization includes install cost, transformers loss, typical low-voltage losses, and under-voltage happening constraints. output of the program is an Excel file "RESULT.xls" that includes all selected and designed transformers capacities, X-Y cordinates and each Load-Transformer connection. (more details can be available if favorite)
Required Products	Global Optimization Toolbox
MATLAB release	MATLAB 7 (R14)
Other requirements	enough RAM and virtual memory

16 Apr 2012	Xiomara	Hello, a few days ago I download the DSP program, I'm still checking to understand the code, but I do not see that there is a manual or instructions. For now the question I have is in the "SP_main.m" in line 68, which means 400 that are within the "if"?, ie in: "if CurrentTrPow (1, count1)> = ceil ((400 * PowerFactor UtilizationFactor *)) " ? Thank you.
