Could you please clarify? I’m afraid I don’t follow you.

For case118, as with any other case, you can minimize losses by setting the 
costs of all generators to an equal positive cost (e.g. $1/MW) and running an 
OPF. The concept of a PV bus is not relevant for the OPF, only for power flow.

Dear all,

As loss optimization for case 118. Case118 with pv bus.

costcase(1,6) = 1 is not enough. It is necessary to have the total active power 
for generators and loads.
