Why Are My Power Flow Calculation Results Different from the Generator Node?

Click For Summary
SUMMARY

The discussion centers on discrepancies in power flow calculation results for a generator node. The user initially reported different values from expected results, specifically the equation for power flow, ##P_2=-1.25e_1f_2-1.25e_2f_1+4.32e_2f_1-e_3f_2-e_2f_3##. The confusion was clarified when the user recognized that the symbol used in the equation represents the complex conjugate, which is crucial for accurate calculations in power systems.

Hello.
This is a power flow calculation of the generator node. I tried calculating several times but I still do not get the same values as this one. This one is the answer, by the way. Can someone explain to me why I got a different answer?

I got:
##P_2=-1.25e_1f_2-1.25e_2f_1+4.32e_2f_1-e_3f_2-e_2f_3##

It's alright now. I just realized the *symbol means complex conjugate.
