  • May 13, 2010: PSAT version 2.1.6. Yet another minor release. Compatible with Matlab 7.10 (R2010a).

  • November 1, 2009: PSAT version 2.1.5. Yet another minor release.

  • June 17, 2009: PSAT version 2.1.4. Minor release that fixes a few bugs.

  • April 21, 2009: PSAT version 2.1.3. Minor release that consolidates device classes and fixes several bugs.

  • June 26, 2008: PSAT version 2.1.2. Minor release that fixes some bugs in the CPF analysis.

  • June 18, 2008: PSAT version 2.1.1. Minor release that fixes a bug in the AVR class.

  • June 16, 2008: PSAT version 2.1.0. PSAT can run on any Matlab version back to 5.3 and on GNU Octave. The GUI for 3D visualization for static and dynamic power system analyses has been completed. The library for Numerical Linear Analysis has been completely rewritten and split into a Linear Analysis library and a Numerical Differentiation library. A filter for the ODM (open data model) has been included. The GUIs have been optimized for running on Quartz (Mac OS X) and X11 (Linux) graphical systems.

  • February 2, 2008: PSAT version 2.0.0. The whole PSAT code has been rethinked and rewritten using classes and object oriented programming techniques. Each device is defined by a class with attributes and methods. The algorithms of PF, CPF, OPF, SSSA and TD have been rewritten, improved and made more robust. The Simulink library has been renewed using "physical" components. This avoids the directionality of control blocks and allows producing high quality network schemes. Added the status field to most components. A component can be put on-line or off-line by toggling its status. New more reliable versions of TCSC, SSSC and UPFC devices and Power Oscillations damper model has been provided by H. Ayres, M. S. Castro and A. Del Rosso. The HVDC model has also been rewritten. Several new filters for data format conversion have been added. Most filters has been provided by J. C. Morataya. PSAT has been tested with very large static and dynamic networks (up to 15000 buses). The logo of PSAT has been changed.

  • November 20, 2007: PSAT version 2.0.0 beta 4. Fully class-based version. 3D visualization of power systems. Several components and models have been completely revised and rewritten. This is an almost stable version and is only compatible with Matlab 7.0 or newer (no GNU/Octave compatibility).

  • March 8, 2007: PSAT version 2.0.0 beta 3 . This is still a development version and is only compatible with Matlab 7.0 or newer (at the moment this version is NOT compatible with Octave). Further class development. Several improvements.

  • December 14, 2006: PSAT version 2.0.0 beta 2. This is a development version and is only compatible with Matlab 7.0 or newer (at the moment this version is NOT compatible with Octave). Further class development. Introduced the connection status for several comments. Several improvements.

  • March 24, 2006: PSAT version 2.0.0 beta 1. This is a development version and is only compatible with Matlab 7.0 or newer (at the moment this version is NOT compatible with Octave). First version of PSAT which uses classes. New more reliable FACTS models and new Power Oscillation Damper model for FACTS devices (by H. Ayres, M. S. Castro and A. Del Rosso). New Simulink library with physical components. New filters for data format conversion (by J. C. Morataya). Improved PF, CPF, OPF, SSSA and TD algorithms. Tested on a 15000 bus network.

  • July 14, 2005: PSAT version 1.3.4. Added multiperiod market clearing model for the PSAT-GAMS interface and many other improvements.

  • January 26, 2005: PSAT version 1.3.3. Minor release with a few bug-fixes and a revised documentation.

  • October 8, 2004: PSAT version 1.3.2. First version tested on Matlab 7 (R14). New Physical Model Component (PMC) Simulink Library. Several bug fixes and improvements.

  • August 2, 2004: PSAT version 1.3.1. Numeric Linear Analysis library by Alberto del Rosso. New model for direct drive synchronous generator wind turbine. PSS/E 29 filter. Several bug fixes and improvements.

  • May 2, 2004: PSAT version 1.3.0. Added a command line version and basic compatibility with GNU/Octave. New wind turbine models and bus frequency measurement. Several bug fixes and improvements.

  • November 25, 2003: PSAT version 1.2.2. Several bug fixes and improvements. Added utilities to convert data files into BPA format and to export PF results to MS Excel sheets and to LaTeX tables.

  • September 11, 2003: PSAT version 1.2.1. Includes previous patch and several other bug fixes.

  • August 31, 2003: PSAT version 1.2.0. Matlab version independent. Several bugs and typos were removed thanks to Liulin.
