How to reduce the mismatch after doing OPF?

I am doing OPF with loss reduction(active & reactive) as the objective, and my control are round switched shunt and transformer tap ratios

But after that, the report shows that my system mismatch is large = 30~40MVA, i'm wondering know how to reduce the mismatch after doing OPF?

thanks!

Isn't it just to solve the network?

So you mean i don't really need to care about the system mismatch?

Have you made a normal load flow calculation with FNSL?

Yes, if I run the normal load flow calculation with FNSL after OPF, the mismatch will be declined. So is it normal with a large mismatch after OPF?

My steps are : first ：made the subsystem doing OPF with loss reduction(active & reactive) →mismatch:30~40MVA second：if i run a normal load flow calculation with FNSL →mismatch<0.1MVA I think the second step will loss the objective, although it made the system balance.
