Parallel Utilities not evenly shared in Load Flow

QUESTION: I wonder why utility do not share 50% each of the load flow current in the circuit below:




ANSWER:

The impedance of the utility is considered in the Load Flow study setup. Given that the two utilities are not identical in size and their impedance, the LF current will not be evenly distributed.



If you choose to exclude the utility impedance, you will need to add a similar impedance cable as encircled below, to simulate the same impedance in your tie breaker branch.
