Dear Power Globers,
Thank you Idris for your input I have updated the case file and it
converged.
I am working on changing topology of the network and finding out it's
effects.If suppose I want to use the tie lines and for restraining radility
opens five section switches say [3 43 48 24 18].
My guess is that opening those lines is creating islands. Use the function
case_info to extract the islands. See
http://www.pserc.cornell.edu//matpower/#pfconvergence for info on
non-convergent power flow.

I’ve just made some changes to the dev version to handle this situation
gracefully. It now prints out a messages telling you that your base and target
cases are identical and returns after 0 iterations, rather than getting stuck
in an infinite loop.

The find_islands() and case_info() function return the bus numbers in each
island, as well as isolated buses, and case_info() also prints out lots of
summary info about each island. If you actually want to extract each island
into it’s own MATPOWER case, use extract_islands().

Hi
Thank you Abhyanker for your input, the example in the manual worked.
I am really new to Matpower and I am learning it from scratch. My intention
is to get the critical value of power and voltage values(Nose point of the
PV curve) of a particular bus, Can anyone please tell me is it possible
runcpf returns a MATPOWER case struct that has the loading/genration and the
voltages at its last continuation step. By using the option 'cpf_stop_at_nose',
the continuation power flow will stop when it is near the nose point. You can
then extract the voltages and power from the MATPOWER case
