Dear All,
I have a general query which naturally popped up after running simulations on
Matpower. I shall be great full if some can answer the question:
Load flow gives us the knowledge of the vector (V,delta,P,Q) at each bus of the
network. In load flow analysis we fix two of them and calculate other two.
So at PV bus voltage is fixed and it can not change. But why in OPF the voltage
even at the PV bus changes? I know optimization is performed on a bigger space
but even then the power flow equations have to be satisfied in OPF. And what
are
the variable quantities at the buses?
Thanks.
Kind regards,
Waqquas
