IEEE 6-bus system is a standard benchmark used for power system stability, load flow, and transient analysis. It typically consists of 6 buses, 3 generators (one slack, two PV), 3 load buses (PQ), and 11 transmission lines. System Configuration Overview : 6 total. : Slack/Swing bus (Reference). Buses 2 & 3 : Generator/PV buses. Buses 4, 5, & 6 : Load/PQ buses. Generators
If you are using MATPOWER, the IEEE 6-bus system data can be written into a standard case file ( case6ww.m ). You can load and run it instantly using the following commands:
While many academic papers use this system, a few specific repositories offer the cleanest data sheets for your simulations:
Ci(Pi)=αi+βiPi+γiPi2[$/h]cap C sub i open paren cap P sub i close paren equals alpha sub i plus beta sub i cap P sub i plus gamma sub i cap P sub i squared space open bracket $ / h close bracket Generator (Bus) Min Cap (MW) Max Cap (MW) G2 (Bus 2) G3 (Bus 3) 4. How to Use This Data in Simulation Software MATLAB / MATPOWER ieee 6 bus system data pdf download
Small enough that load flow equations can be partially verified manually or using basic spreadsheet software.
Typically designated as Bus 1, Bus 2, and Bus 3. Bus 1 is conventionally chosen as the slack (swing) bus.

To give you an idea of what to expect in your PDF download, here is a typical representation (values in per-unit on 100 MVA base):
: Identifies bus type, initial voltage magnitudes, phase angles, and real/reactive generation and load values. : Includes resistance ( ), reactance ( ), line charging susceptance ( ), and transformer tap ratios. Generator Data : Contains active power limits ( cap P sub m i n end-sub cap P sub m a x end-sub ), reactive power limits ( cap Q sub m i n end-sub cap Q sub m a x end-sub ), and cost coefficients for economic dispatch.
