PowerSAS.m is a robust, efficient and scalable power grid analysis framework based on **semi-analytical solutions (SAS)** technology. 
The PowerSAS.m is the version for MATLAB/Octave users. It currently provides the following functionalities (more coming soon!):
* Steady-state analysis, including power flow (PF), continuation power flow (CPF), contingency analysis.
* Dynamic security analysis, including voltage stability analysis, transient stability analysis, and flexible user-defined simulation.
* Hybrid extended-term simulation provides adaptive QSS-dynamic hybrid simulation in extended term with high accuracy and efficiency.

.. ANDES is a Python-based free software package for power system simulation, control and analysis.
.. It establishes a unique **hybrid symbolic-numeric framework** for modeling differential algebraic
.. equations (DAEs) for numerical analysis. Main features of ANDES include

.. * a unique hybrid symbolic-numeric approach to modeling and simulation that enables descriptive DAE modeling and
..   automatic numerical code generation
.. * a rich library of transfer functions and discontinuous components (including limiters, dead-bands, and
..   saturation) available for prototyping models, which can be readily instantiated as multiple devices for
..   system analysis
.. * industry-grade second-generation renewable models (solar PV, type 3 and type 4 wind),
..   distributed PV and energy storage model
.. * comes with the Newton method for power flow calculation, the implicit trapezoidal method for time-domain
..   simulation, and full eigenvalue calculation
.. * strictly verified models with commercial software. ANDES obtains identical time-domain simulation results for
..   IEEE 14-bus and NPCC system with GENROU and multiple controller models. See the verification link for details.
.. * developed with performance in mind. While written in Python, ANDES comes with a performance package and can
..   finish a 20-second transient simulation of a 2000-bus system in a few seconds on a typical desktop computer
.. * out-of-the-box PSS/E raw and dyr file support for available models. Once a model is developed, inputs from a
..   dyr file can be readily supported
.. * an always up-to-date equation documentation of implemented models

.. ANDES is currently under active development. To get involved,

..   `Modeling Cookbook <https://andes.readthedocs.io/en/stable/modeling.html>`_

.. This work was supported in part by the Engineering Research Center Program of
.. the National Science Foundation and the Department of Energy under NSF Award
.. Number EEC-1041877 and the `CURENT <https://curent.utk.edu>`_ Industry Partnership Program.
.. **ANDES is made open source as part of the CURENT Large Scale Testbed project.**

.. ANDES is developed and actively maintained by `Hantao Cui <https://cui.eecps.com>`_.
