Hi Prof.Ray,
I found the mistake that I forgot to transfer the W to KW while combining
two systems. Thanks.
Regards,
Chixin

Subject: Power flow while involving radial systems
Dear Prof.Ray,
The runpf and the runopf did not converge while handling a revised system
(i.e., IEEE 30 and IEEE 33). The revised system is attached. Could you give
me some suggestions when you feel convenient? Thanks.
The revising details: a standard IEEE 30 bus system [] is revised by
connecting the bus 2 to the bus 1 of an IEEE 33-bus radial system [] which
consists of 33 buses, 32 lines, a voltage of 12.66kV, load size of
3.715MW and 2.3MVar.
In the new combined system, the original bus-index of the IEEE 33-bus has
increased 30 (i.e., the original bus-index 1 corresponds the new index 31, and
so on). The resistance and reactance between bus 1 and bus 31 are 0.2030 (p.u.)
and 0.1034 (p.u.) respectively.
Regards,
Chixin
