Power System Dynamics, Stability, and Control Research Center

Software

We are actively developing two tools for power system analysis designed for research and educational purposes: (i) PGAz on the MATLAB platform, and (ii) PyGAz on the Python platform, both developed primarily for research and educational purposes.

About PGAz

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. Therefore, please understand that PGAz has not been released as a fully open-source tool yet. At this stage, the updated models and algorithms are only shared with the core team and collaborators, as the platform is still actively being developed and refined.

Currently, PGAz provides six core features:

Power Flow (PF)
Continuation PF (CPF) and Optimal PF (OPF)
Quasi-Dynamic Simulation (QDS)
Small-Signal Stability Analysis (SSSA)
Time-Domain Simulation (TS)
Bifurcation Analysis (BA)

PGAz Updates

30 April 2026 — Develop new 3-phase static models for line and bus, enable 3-phase and unbalanced PF, OPF, and CPF in PGAz. Verify this using IEEE benchmarks and n-bus systems. Solvers for 3-phase unbalanced PF, OPF, and CPF are optional including standard solvers such as NR, GS, FD, and IW. Pannavich helps out with the development. [Sorasak]
25 March 2026 — A sparse matrix technique was applied to the Jacobian matrix in certain numerical solvers to accelerate PF, CPF, OPF, and TS. An adaptive sparsity pattern based on the actual system topology was employed to reduce computational overhead and improve robustness (e.g., mitigating convergence failures) in large-scale systems, thanks to Dr Nawakun Triruttanapiruk from KMUTNB. Verified using "case13659pegase" and other large systems transcoded from MATPOWER. [Sorasak]
10 March 2026 — Release PGAz version 1.2 for educational and learning purposes, bugs fixed, major improvement in GUI, and several models and test systems included. [Sorasak]
14 February 2026 — Major revisions were made to PGAz GUI, algorithms, model representation in PGAz Library, result logging systems, etc. We also removed demo versions from the website. [Sorasak]
22th December 2025 — Since 20 December 2025, updated versions of PGAz are NO longer open-source or publicly available. Development still continues, but updates and newer versions are shared only within the team and collaborators. For learning and educational uses, we believe that PGAz version 1.1 is sufficient.
7th December 2025 — Added two tutorial videos: (i) the user-defined model and (ii) the PGAz Simulink Library (see Download PGAz). [Sorasak]
1st December 2025 — Improved the PGAz Simulink Library by updating icon colors (blue for DC, black for AC), adding an optional nonlinear TS with the linear TS as default, remodeling the DC fault, and fixing various bugs. [Sorasak]
28th November 2025 — Added tutorial videos for CPF, OPF, SSSA, and TS (see Download PGAz) [Sorasak]
26th November 2025 — Added a tutorial video for PF analysis (see Download PGAz), fixed minor and major bugs, and wrapped up the remaining unfinished/unverified models [Sorasak]
3rd November 2025 — PGAz v1.1 has been released! This update includes several bug fixes, improved solvers and algorithms, and the addition of new and more stable models. Note: TS for nonlinear DAEs is not included yet in this version — it still needs more testing to improve robustness and trade-off between computational time and simulation accuracy [Sorasak]
28th October 2025 — The following major update are made:
- Update and correct the models and solvers for TS so they can handle large disturbances accurately (such as faults, line trips, and breaker operations) by performing time integration on a system of nonlinear DAEs. This replaces the old model, which was based on linearized DAEs and therefore only accurate for small disturbances. With this update, TS can now return more accurate responses under large disturbances. However, TS is available for both linear and nonlinear DAEs with a trade-off between computational time and simulation accuracy
- We are wrapping up these updates with minor and major bug fixes, model/solver verification, and adding several new models. These will be included in PGAz v1.1, a more stable version, coming soon

Add the exponential linear unit (ELU) activation function for ANN-PSS and ANN-POD as another activation option. Also apply the concept of multi-slack and multi-area conditions for PF and OPF with new solvers to run more effectively when the system is reconfigured under these conditions. Also verify this as well [Sorasak]
4th October 2025 — Include a tutorial video link (see Download PGAz). Future tutorials on basic functions and features in English will also be accessible through this link [Sorasak]
3rd October 2025 — The following major updates are made:

PyGAz Updates

19th May 2026 — Validated AVR/PSS/AC1A/DC1A/ST1A/DC2A models, started developing dynamic models for GFL IBRs and the control platform, and rechecked PF/CPF and fixed related bugs. [Nonthachai]
8th May 2026 — Continued improving and benchmarking the PF/OPF framework in PyGAz. All AC/DC PF methods (NR, GS, FDLF, LM, and DC PF) now run successfully from IEEE 14 up to large PEGASE systems (1354 and 2869 buses), verifiy the results against MATPOWER. Added automatic MATPOWER .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]
30th April 2026 Start developing dynamic models of SG and associated control devices (AVR, PSS), validated via TS and SSSA, with further verification with PGAz (also thanks Sorasak for supporting) and PSAT. Also develop RK4, Modified Euler, and Trapezoidal IMEX solvers for TS. [Nonthachai]
6th April 2026 — Tightening model checks, refining AC PF calculations, improving NR convergence, enhancing PV bus limit handling, and polishing outputs and OPF reports [Nonthachai]
26th March 2026 — Added new features to PyGAz, such as CPF and PV curve analysis, also improved the GUI and overall system, fixed bugs, and started including basic dynamic models (i.e., SG and start developing IBR model) with current injection coupling, developed disturbance models, including abrupt changes within devices, faults, and tripping events, and implemented time-integration methods such as RK4, recheck the robustness of solvers, etc. Big thanks to P'Nui Sorasak for reviewing, providing ideas, and guiding the development. [Nonthachai]
18th March 2026 — DC PF validated; finalization and benchmark testing next, followed by DC OPF development. [Nonthachai]
11th March 2026 — PyGAz PF module is now completed, including verification with standard IEEE test systems, incorporation of a DC PF formulation and basic constraints and limits, as well as basic solvers. Also update on OPF. [Nonthachai]
6th March 2026 — The PyGAz project has undergone a major revision, including significant improvements to its foundational framework, structural design, GUI, and GNE, with development continued by Nanthachai. [Tossaporn]
26th October 2025 — Develop small-signal models for SGs and their associated control devices, such as AVR, TG, and PSS. Try to develop the models and couple their dynamics to the system through PQ injections based on the system admittance matrix, now done. Again, revisit static PF and OPF models and solvers to ensure their accuracy, flexibility, and correctness [Tossaporn]
27th September 2025 — I decide to go back and fix minor bugs in PF/OPF and ensure that the solvers are robust enough to handle problems fairly without bias during implementation. [Tossaporn]
1st September 2025 — Begin developing the OPF and remodel the related system models to support OPF calculations. Fix minor bugs in how PF calculates the objective or losses, and generalize this for all solvers [Tossaporn]
21th August 2025 — Recode major models and functions into an object-oriented structure, improve PF format export, standardize the PF objective, and generalize the objective function for the PF problem [Tossaporn]
15th August 2025 — Run into cascading errors during the full object-oriented programming conversion, pause this for now, and go back to updating the PF solver, making other solvers more robust by adding an initial-guess algorithm, and adding supervised machine learning to the new PF solver [Tossaporn]
14th August 2025 — A good time to refactor PyGAz into an object-oriented structure and plan for the future model, defining all core classes, enhancing solver robustness, fixing bugs along the way, and testing incrementally. [Tossaporn]
12th August 2025 — Before moving on, to make things more reusable and easier to manage, I think I should organize the functions and classes into a proper object-oriented design—it will really help with future development of PyGAz. So, it is better to fix the current issues and set everything up using object-oriented programming for now [Tossaporn]
10th August 2025 — PF analysis in PyGAz is now complete! Still updating in case any bugs occur. Running PF in PyGAz now has 4 basic (GS, NR, FD, IPM) solvers, 3 stochastic (PSO, GA, SDE) solvers, and 1 intelligent-based solver (Pi-ANN, thanks to the super handy “torch” library from PyTorch). Tested and verified from IEEE 3-bus all the way up to IEEE 300-bus systems. Next steps: will improve the stability of PF execution, exporting PF results, develop a conversion function for importing systems from other sources/tools, and then proceed to OPF [Tossaporn]
9th August 2025 — Run into some PF issues while trying different solvers. Thorough verification is essential, normalizing the PF objective greatly improved performance and is now complete. However, the parameters for each solver still require manual tuning, which can be somewhat subjective [Tossaporn]
8th August 2025 — PF analysis in PyGAz is partly done. PF are tested susing three basic algorithms, Gauss-Seidel, Newton-Raphson, and Fast Decoupled Load Flow, verified in IEEE 3-bus, 5-bus, ... up to 57-bus systems. Still, there is some more works to do to make them run more smoothly and robustly. The main GUI still runs into a few problems—like not being able to export results properly—and overall stability needs more polish. Also thinking ahead, we plan to develop a graphical network editor with a user-friendly interface [Tossaporn]
6th August 2025 — The initial version of PyGAz's main GUI is complete. Updates will be made regularly as core functions are integrated. At this stage, I think it is applicable to focus on and revisit developing basic simulation features such as PF, OPF, QDS, SSSA, and TS [Tossaporn]
3rd August 2025 — Started developing and designing the main GUI for PyGAz, [Tossaporn]
30th July 2025 — Kick off the PyGAz project! [Tossaporn]
