Re: LMP calculation using MATPOWER

2015-07-31 Thread Abhyankar, Shrirang G. 
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 
(http://www.pserc.cornell.edu//matpower/docs/ref/)

The best way to split the LMP into components is outside the scope of this 
list, but you may want to start with a reference like …

for electric power systems," Power Systems, IEEE Transactions on , vol.17,

summary of where to find the shadow prices of the various constraints in

RE: LMP calculation using MATPOWER

2015-06-29 Thread Nandu Balachandran 
Dear Dr.Zimmerman,

What is the best way to spit LMP into three components?

In order to split LMP into energy , congestion, and loss , we need Lagrangian 
multiplier of energy mismatch at reference bus and Lagrangian multiplier of 
transmission constraint. Does MATPOWER gives these values along with opf 
solution.
If not how do we calculate these components?

Appreciate your help.

LAM_P is the overall LMP. If you want to break it into components, you would 
have to do that yourself.

We could split LMP into three components . ( LMP of energy+ Congestion + Loss).

So is LAM_P is Lagrangian multiplier of just energy component of LMP ?
If so, does MATPOWER provides any function to calculate overall LMP considering 
energy, congestion, and loss.

RE: LMP calculation using MATPOWER

2015-06-25 Thread Nandu Balachandran 
Dear Dr. Zimmerman,

Thanks a lot for your help. I have few more questions.

We could split LMP into three components . ( LMP of energy+ Congestion + Loss).

So is LAM_P is Lagrangian multiplier of just energy component of LMP ?
If so, does MATPOWER provides any function to calculate overall LMP considering 
energy, congestion, and loss.

Thanks and appreciate your help,

Dear Nandu Balachandran,
   There is inbuilt function in
MATPOWER to know the LMPs at all the buses. If you want to calculate LMPs
for a particular system run OPF and see the results, in OPF results one
function called Lamada this indicates LMPs at all the buses. I think direct
