I don’t think there exist built-in MATPOWER functions to calculate loss and
delivery factors. However, you can easily compute them, and possibly think
about contributing, using the available MATPOWER functions. The full list of
available functions can be found here

One more question Dr. Zimmerman
Is there a built in function to calculate loss factor or delivery factor ?

Hi MATPOWER users,
If you don’t see responses from me here during August, it’s nothing personal.
Other deadlines and vacation schedules will be keeping me away for a while. So
this is a good time to appeal to those of you with more MATPOWER experience to
lend a hand to those with questions.
As
You have offered a total of 150 MW of generation, but the system includes more
than 150 MW of fixed loads, plus the dispatchable loads that are being bid. So
there is no feasible solution. With those offers and bids, you’ll need to
decrease the loads in the PD column of the bus matrix to get fea
Thank you so much Carleton!
Best,

Thanks João. Sorry I haven’t responded to your earlier e-mail about this issue.
I’ve been swamped with other deadlines and haven’t yet had a chance to take a
look at this. Just wanted to let you know that I have taken note of this and
will be sure to check it out and incorporate any fix as soon
It’s in the LAM_P column of the bus matrix.

Hi Senam,
The best source I know of for distribution system data is the PES Distribution
System Analysis Subcommittee's
Distribution Test Feeder Working Group.

Good point. I think that assumption is valid as long as the real power losses
in the branch are positive, which should be the case with positive branch
resistance. However, negative resistances, particularly in systems with
equivalenced lines, are not unheard of. Though in those cases, you typic
Hi All,
Can anyone help me with case 33? I need to run a simulation on a
distribution system. Where can I download case 33 for example?
Thank you for your help.

Dear all,
After reviewing the code I believe this is caused by the sparse matrix
creation command for the Bf matrix.
In the case in question the Bf matrix must have an empty last row. But
since no element of this row is provided to the sparse command it creates a
Bf matrix with a missing row.

Dear Matpower community,
For a DCOPF with a dc line a simple change in the bus order causes an error
in matpower 5.1.
Attached are the .m files for a 4-bus system with 2 x AC and 1 x DC lines.
Presenting the DC bus in the branch matrix before last results in the error
below.
