I find that depending on the source of the data there can be small differences in the parameters used in some of these standard IEEE systems. There can also be different default assumptions used regarding how certain controls are handled in MATPOWER and PowerWorld. For example, it’s possible that PowerWorld will modify the tap ratio of a transformer or the state of a switched capacitor in order to maintain a controlled voltage, whereas MATPOWER does not adjust any controls automatically.
Attached is a MATPOWER case file that was exported from the PowerWorld file you
attached. I don’t know if it’s different from the MATPOWER case you were using.
