Dear Chixin Xiao, if you have executed it already, the avoid this message. Otherwise i have attached corrected case30 combined with case33.

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
