We are actively developing two tools for modern power system analysis: (i) Power Grid Analyzer (PGAz) on the MATLAB platform, and (ii) Python-based Power Grid Analyzer (PyGAz) on the Python platform, both developed primarily for research and educational purposes.
Based on our previous experience, fully open-source development has shown limitations in responsiveness, as new models often remain at a research or conceptual stage and are not available for timely practical use. Such approaches may also be unsuitable for certain application areas and present coordination challenges. Meanwhile, existing open-source and commercial power system analysis tools remain prevalent and can be extended to meet evolving needs. Please note that PGAz has not yet been released as a fully open-source tool. For now, only the educational version is publicly available. The advanced models and algorithms remain accessible only to the core development team and selected collaborators while the platform continues to be actively developed, tested, and refined.
Currently, PGAz provides six core features:
PGAz is provided as an educational tool and is available for download below. Before installation, please ensure that MATLAB is installed and that all required basic MATLAB toolboxes and supporting packages are available. Detailed installation instructions, along with an overview of the fundamental functions and features, are provided here. The User Manual can be download here.

Owing to its accessibility, versatility, costless, and open-source nature, Python has become a leading programming language for developing advanced tools across engineering, education, and scientific research. We are developing the Python-based Power Grid Analyzer (PyGAz), for research-oriented power system analysis. PyGAz is developed using Python 3.x. The PyGAz project is under ongoing development.
PyGAz is currently under development and will be available soon.
.m file importing and conversion directly into the PyGAz format. Also continued CPF validation against MATPOWER/literature references, expanded OPF testing, and improved GUI workflows and GNE drag-drop execution paths. [Nonthachai]
