Dear all,
I would like to ask something more about LMPs. Is there any function
like DCOPF that incorporates the impact of losses in
the calculation of LMPs, like the models (that are now applied in PJM,
NYISO etc.) which explicitly balance the losses in the energy balance
equation?
Thank for your comments.
Regards Gregory.

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 or loss cost
the energy can
be distributed to all nodes at the same price.

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 account both supply
(generation/import)
bids and demand (load/export) offers and the physical aspects of the
transmission system including transmission and other operational
constraints.
When it is performed a DCOPF, Matpower shows LMP for each bus
considering
the marginal cost (energy cost) and the congestion cost so that
I'd like to
know why the generation constraints (maximum and minimum power) aren't
considered in the LMP.
Thank you so much for your ideas and comments.
Regards,
Vh
