This set of functions contains several methods for the power flow analysis of power distribution networks for the static case and quasi-dynamic simulation. The European low voltage test feeder is used as an example. However, the program can deal with other systems if the input file is organized correctly. Execute files Example_01.m and Example_02.m to see the use of each function. Example_03 may take some time because it calculates the power flow in 1440 scenarios.
The methods considered are the following:
  • Conventional Newton's method in the real domain.
  • Newton's method in the complex domain
  • Backward-forward sweep algorithm (it is assumed the grid is ordered and the slack is node 1)
  • Fixed-point iteration.
The input file is an excel workbook with six worksheets: lines, line_codes, loads, profiles, coordinates, and general. See the example to identify the information in each file.
The toolbox does not require any functions different from the standard Matlab set, xlsread() for reading excel files and sparse() for creating sparse matrices.
