Hi,
my question is about the voltage level of each buses in a radial
distribution system. My understanding of this phenomena is that the
voltage level of the "farest" (in term of r and x) bus will have the
lowest voltage level if there is no generation or voltage regulator
between the slack
In general, the voltage tends to drop as you get further from the source, if
loads are evenly distributed and line parameters are similar. In your example,
however, you have a much larger load at bus 9 than at bus 8, and in particular,
there is a large reactive load at 9, pulling down the
Dear Prof. Zimmerman,
I have a question about Local Marginal Prices (LMP) that are shown in
Matpower.
The definition of the LMP is the marginal cost of supplying, at least cost,
the next increment of electric demand at a specific location (node) on the
electric power network, taking into
Dear Victor,
If there is no congestion in the network, there is the same LMP at all the
nodes.
The LMP consists of loss, congestion, and energy costs. DCOPF has no
losses, and if there is no congestion only the energy cost is accounted
for.
You can think of it as if since there is no congestion
Hi Abdelkrim,
I would recommend you have a look at the paper,
Baran, M.E.; Wu, F.F., "Optimal sizing of capacitors placed on a radial
distribution system," in Power Delivery, IEEE Transactions on , vol.4, no.1,
pp.735-743, Jan 1989
It has a nice mathematical formulation of how voltage drops
