Hi Jovan,
I do not know of any papers comparing the two cases, but I can tell you a
little bit about how we use the concepts of electrical distance excluding
loads. Our company produces decision-support tools for real-time
transmission operators, which are fully based on algorithmic, model-based
Jose,
I am interested in applications of electrical distance idea excluding the
loads. I would
like to read some papers/reports which compare real life networks using
electrical
distance with and without the loads. I might be completely wrong, ignoring
the load
might be useful in some situations.
OK thanks, I see what you mean now.
The way I see it, I was looking at just the *network*, not the network+load
system. In this view, you calculate bus A to bus B distances using just
the admittances of the transmission network. In other words, the electric
circuit we're considering here has all
Jose,
Let me clarify. If you run a power flow you can obtain all the currents
and transfer the
constant P/Q loads into constant RLC you can rebuild your admittance matrix
with
this new RLC values. From here, calculating the electrical distance using
Z matrix
is nothing new. However, as soon as
Hi Jovan, all,
Thanks for contributing those points!
It's interesting to note that the resistance distance between nodes can
also be calculated by simpler eigen/spectral techniques, as in
http://repository.ias.ac.in/77807/ and so matrix inversions aren't
essential. Anyway, I more meant "quick
Jovan,
I agree it's not fast and efficient, as it involves inverting the
admittance matrix. However, I do not see why not Klein's impedance
distance could be used in power networks. I mean, the fact that some (ok,
most) injections are expressed as constant power does not invalidate the
fact that
Paul,
I would not call calculating Zbus "fast and efficient". Also, using
resistance distance
might make sense in standard electric circuits but it does not make sense
in power
networks with constant powers.
As far as I know there is not a very good, theoretically sound, way of
calculating elect
Hi Hans,
There is indeed a fast and efficient way to calculate this, though you
don't encounter it often in the power systems literature.
You can use the Klein resistance distance, as defined here:

Once you have inverted your Ybus matrix t
Hello everybody,
I was wondering if somebody had already the following issue:
I would like to create a "full version" of the Y-matrix, i.e. a matrix where
(as long as there is only one synchronous grid) the admittance between each bus
is given, even if the bus are not connected directly by one b
