**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.
|
|
|
|
### Key features
|
|
* **High numerical robustness.** Backed by the SAS approach, the PowerSAS tool provides much better convergence than the tools using traditional Newton-type algebraic equation solvers when solving algebraic equations (AE)/ordinary differential equations (ODE)/differential-algebraic equations(DAE).
|
|
* **Enhanced computational performance.** Due to the analytical nature, PowerSAS provides model-adaptive high-accuracy approximation, which brings significantly extended effective range and much larger steps for steady-state/dynamic analysis. PowerSAS has been used to solve large-scale system cases with 200,000+ buses.
|
|
* **Customizable and extensible.** PowerSAS supports flexible customization of grid analysis scenarios, including complex event sequences in extended simulation term.
