Power Flow Calculation for Generator Node: Understanding Different Results

Click For Summary
SUMMARY

The discussion focuses on the discrepancies in power flow calculations for a generator node. The participant initially presented an equation for power flow, specifically $$P2=−1.25e_1f_2−1.25e_2f_1+4.32e_2f_1−e_3f_2−e_2f_3$$, and sought clarification on the differences in results obtained. It was clarified that the symbol used in the equation represents a 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:
$$P2=−1.25e_1f_2−1.25e_2f_1+4.32e_2f_1−e_3f_2−e_2f_3$$

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