Findings• Restrictions necessary on the PE site to
slow down the course of events.• Use the same measuring point for all
control loops in the LP net.

Findings• Restrictions necessary on the PE site to
slow down the course of events.• Use the same measuring point for all
control loops in the LP net.• Feed forward needed in boiler control• Dynamic simulations necessary prior to
mayor changes.
