PowerSAS.m
|
|
==========
|
|
|
|
**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.
