Hi Ray,

I am a new user of MATPOWER and MATACDC ana a Ph.D student @ University of Manitoba. I have downloaded and installed MATPOWER 4.1 with Matlab version 7.10. I am working with IEEE 39 bus case and noted that there is a discrepancy in terms of loads at buses with the data I have from http://publish.illinois.edu/smartergrid/ieee-39-bus-system/ and that in case39. The same has been highlighted in some postings here too.

I have 3 simple questions:-
Q1. A very basic one - When I enter data in the bus struct the value for Vm and Va can be 1 and 0 respectively. Since the Volt. magnitude and Volt. angle will be computed by load flow. (As I understand). Q2. I did enter the data as provided in the Univ. of Illinois site mentioned above and I found that my case did not converge?
 Q3. Is it possible to find the eigenvalues of AC-DC system using MATPOWER?

Since I am working with this data can you please throw some light as to how I can resolve the issue. I will be very grateful.
