768 eng reportzib 0 2003-12-15 2003-12-15 -- The operative planning problem in natural gas distribution networks is addressed. An optimization model focusing on the governing PDE and other nonlinear aspects is presented together with a suitable discretization for transient optimization in large networks by SQP methods. Computational results for a range of related dynamic test problems demonstrate the viability of the approach. 03-46 769 urn:nbn:de:0297-zib-7687 Appeared in : Modeling, Simulation and Optimization of Complex Processes, H.
