PSAT

The Power System Analysis Toolbox (PSAT) is a Matlab toolbox for electric power system analysis and simulation. The command line version of PSAT is also GNU Octave compatible. All operations can be assessed by means of graphical user interfaces (GUIs) and a Simulink-based library provides an user-friendly tool for network design.

PSAT is ditributed under the General Public License (GPL) and comes with no warranty conditions. The latest PSAT version can be downloaded here.

The main features of PSAT are: Power Flow; Continuation Power Flow; Optimal Power Flow; Small Signal Stability Analysis; Time Domain Simulation; Complete Graphical User Interface; User Defined Models; FACTS Models; Wind Turbine Models; Conversion of Data Files from several Formats; Export results to EPS, plain text, MS Excel and LaTeX files; Interfaces to GAMS and UWPFLOW Programs; Command Line Usage; and GNU Octave Compatibility.


A brief introduction to PSAT is available here. This presentation was given at the first IEEE panel session on Open Source Software at the PES Meeting of Montreal, Canada, on June 20, 2006. A didactical tutorial to PSAT is available here.

Letters of reference for PSAT are available here. If your University, Institution or Company is using PSAT, please send me a letter of reference. These letters are important for me in order to request funds to my University and, in turn, to keep developing PSAT.

The PSAT documentation is no longer provided for free. Please contact me for getting the details on how to obtain the full PSAT manual as well as any other assistance on PSAT. I am also available for defining as hoc appointments for developing specific features currently not implemented in PSAT.
