Below are the links of the two types of IEEE test systems for power system analysis.

The first one is the IEEE radial test feeders for distribution system analysis, located at http://www.ewh.ieee.org/soc/pes/dsacom/testfeeders.html. The test feeders are 13 bus, 34 bus, 37 bus and 123 bus feeders including all the required data and sample power flow simulation results.

The second one is a non-radial test feeders, http://www.ee.washington.edu/research/pstca/, that is preferrably used to test power system studies and analysis for transmission system level. It includes 14 Bus, 30 Bus, 57 Bus, 118 Bus, 300 Bus test system for Power Flow Studies, and 17 Generator (with 162 bus power flow case), 30 Bus “New England” Dynamic Test Case, and 50 Generator (with 145 bus power flow case) for dynamic test cases.
