As allowed network and software developments to possibly perform

As the figure shows the different levels of architecture.
InterPSS simulation engine provides a detailed analysis for systems’
functionalities and architecture. The software provides a real-time simulation which
serves several frameworks. For instance, InterPSS is distinguished by its loosely
and flexible coupling system architecture. It allows power system solution
providers or third parties to plug in their own simulation modules. In addition,
it serves the system integrators to plug in their standard-based software
infrastructure and integrate it easily with InterPSS. (InterPSS,
InterPSS 2.0, n.d.)

InterPSS contains multiple functions analysis that are
available and other functions that are still under development. It contains,
for instance, AC and DC load flow simulation analysis. It sends simulation
requests with simulation input data which simulates the engine. The later
replies with a response after completing a certain calculation.  It also includes function analysis for short
circuit, transient stability and distribution system analysis. Further
development for the software which includes protective relay coordination and
harmonics analysis. Moreover, it will include the dynamic stability and reliability
for small signals.

As it can be shown in the figure above, InterPSS 2.0
interface is also based on Google Spreadsheet. The User power system simulation
input data and simulation results and reports are all saved in Google’s drive.
The data is protected under Google’s Information Security and Privacy
properties. (InterPSS, InterPSS 2.0, n.d.)

 

Applications and implementations:

The software services currently provides three available
services.

Grid Computing:

Recent technological advances allowed
network and software developments to possibly perform cloud grid computing for power
grids that are locally or remotely located. With traditional network and
computing technologies, it was impossible to meet the requirement of power
system real-time simulation due to the huge amount of contingency analysis
cases that should be evaluated in a short periodic time. Furthermore,
traditional computers used to have only a single CPU which hardly provides, for
instance, an accurate AC loadflow power network model. Thus, further manual
approximation and regularization needed to be done to reach that.

Modern network and cloud based computing have
successfully facilitated the traditional challenges.  Grid computing solved power system real-time
simulation problems using multiple CPUs which provide an accurate AC loadflow
model. A Chinese university conducted an experiment using InterPSS Grid
computing. The research group simulated the loadflow based on 1245 buses and
1994 power branches.
