Depending on the complexity of the network, systems of index~1 or index~2 can arise. We then apply Model Order Reduction (MOR) techniques such as Proper Orthogonal Decomposition (POD) to a network of moderate size and complexity and show that one can reduce the system size significantly. This can be either achieved by directly reducing the original DAE~formulation or by applying MOR to an index-reduced system. First numerical results are reported on.1 Online-Ressource (18 Seiten = 0,3 MB) : Diagrammeenghttp://rightsstatements.org/vocab/InC/1.0/510Book
