Re: mdo Summary error

[Ray Daniel Zimmerman]

So, the issue is that the case is infeasible. From looking at the code, I don’t 
see how mdo.results.success can be true in that case. You may want to check 
that again.

I suggest you try relaxing various constraints until you find the one causing 
the problem. And if you haven’t already, make sure you can solve a simple DC 
OPF successfully on the cases for each individual period.

Hope this helps,

   Ray

These are :

The exitflag apears to be -4, when i gone through debugging.
Here is the code, you can check above values.

What are the values of the following?

mdo.QP.exitflag
mdo.idx.nt
mdo.idx.ntramp

I’m just looking into the most() code to look for a reason this field may not 
be assigned. Feel free to do your own similar debugging to find the problem. 
The only way I can see that it’s possible for a multi period problem is if 
mdo.QP.exitflag is less than or equal to 0.

Have you confirmed that the case solved correctly by checking 
mdo.results.success? That seems the most likely cause for non-existence of the 
mdo.results.Rrp field.

Subject: mdo Summary error

Respected Ray,
when I run the file(of wind generators into 30 bus ) I get probably the 
deterministic results of the case(refer to the pictures attached). I think when 
most_summary command is unable, then it gives such results but when I enable 
ms=most_summary, I get error as following:

Reference to non-existent field 'Rrp'.

Error in most_summary (line 62)
   Rup = [zeros(ng, 1) mdo.results.Rrp];
Error in most_ex7_suc_edit (line 101)
  ms = most_summary(mdo); )


How can I remove this error?
Thanking you in advance.
