Thermogravimetric analyzer was applied to analyze 22 solid materials and their mixtures at a heating rate of 10 K min−1 under nitrogen atmosphere. A grey-relation-based method for thermogravimetric (TG) data analysis was proposed, which introduced a mass loss vector (MLV) as numeric form of TG curves and calculated grey relations between MLVs of different materials as criterion. The method was applied to TG data, exemplifying its applications in classification of some solid wastes, simulation of biomass based on three compositions and interaction analysis of two materials. The results indicated that paper category could be represented by cellulose below 673 K while textile category could be represented by cellulose and polyethylene terephthalate (PET). 12 kinds of biomass could be simulated with all relation values larger than 0.92 between experimental and calculated data. Influences of interaction between PVC, paper and poplar wood were quantitatively analyzed, which showed less influence between paper and poplar than PVC and poplar.

Die Entwicklung des mitteleuropäischen Energiesystems und insbesondere die Weiterentwicklung der Energieinfrastruktur sind konfrontiert mit einer stetig steigenden Diversität an Herausforderungen, aber auch mit einer zunehmenden Komplexität in den Lösungsoptionen. Vor diesem Hintergrund steht die Weiterentwicklung von Hybridnetzen symbolisch für das ganze sich in einer Umbruchsphase befindliche Energiesystem: denn der Notwendigkeit einer Schaffung und Bildung der Hybridnetze aus systemischer und volkswirtschaftlicher Perspektive steht sozusagen eine Komplexitätsfalle gegenüber, mit der die Branche in der Vergangenheit in dieser Intensität nicht konfrontiert war.
