Dear All,
I am modeling blackout in matpower. I have some success as long as no
isolated buses are formed. However when I have isolated buses, I receive
the following command error:
*Index exceeds matrix dimensions.*
*Error in dcpf (line 46)*
*Va([pv; pq]) = B([pv; pq], [pv; pq]) \ (Pbus([pv; pq]) - B([pv; pq], ref)
* Va0(ref));*
*Error in runpf (line 161)*
* Va = dcpf(B, Pbus, Va0, ref, pv, pq);*
*Error in rundcpf (line 93)*
*[varargout{1:nargout}] = runpf(casedata, mpopt, fname, solvedcase);*
*Error in untitled3 (line 70)*
*results=rundcpf(mpc);*
I model blackout by removing the attacked transmission lines in each loop.
After some loops islands are formed. Then I cannot go further. I tried
using the followoing command: extract_islands(mpc,1) but still gives the
same command error. How do I solve this problem? How do I find out isolated
buses and set its index to 4 (meaning non-used)? Any help is appreciated.
best,
Bijay
