Hey guys, I am using PSSE V32 to run a dynamic fault study however there seems to be a significant mismatch between Pelec/Qelec and Flow(Q+P) outputs. For example in this case there is an inverter at bus 903 and after the fault the Pelec/Qelec go back to values that are expected, however the Flow(Q+P) to the bus it is connected to 901 are quite different. Any help would be appreciated, Thanks image description

Is there any more equipment connected to bus 903?

The only equipment connected to bus 903 is the Generator and the transformer to bus 901

Pelec & Qelec values are in pu of system base (=100) and to get true values, just multiply their values by 100. After doing that, Pelec = Flow P. Qelec + Qloss at bus 903 (=transformer admittance) = Flow Q
