Digitalization and concepts such as digital twins (DT) are expected to have huge potential improve efficiency in industry, particular, the energy sector. Although number maturity of DT is increasing, there still no standardized framework available for implementation DTs industrial systems (IES). On one hand, most proposals focus on conceptual side components leave details unaddressed. Specific implementations, other rarely follow recognized reference architectures standards. Furthermore,...
Renewable-dominated power grids will require industry to run their processes in accordance with the availability of energy. At same time, digitalization introduces new possibilities leverage untapped optimization potential provide this flexibility. Mathematical methods such as mixed-integer linear programming (MILP) are widely used predict optimal operation plans for industrial systems. MILP models difficult adapt, but viability predicted relies on accurate underlying actual behavior. New...
This work examines a high temperature latent heat storage system, which could find use in future concentrated solar power and other combined plants. In contrast to lab-based fully charged or totally discharged states, partial load states will be the principal operation real-world applications. Hence, closer look on effective rates are worthwhile for successful implementation of this type. A vertical finned shell tube exchanger pipe with combination transversal longitudinal fins is applied....
The sandTES technology utilizes a fluidized bed counter current heat exchanger for thermal energy storage applications. Its main feature is an imposed horizontal flow of sand (SiO2) particles by vertical air across consisting several rows tubes. Past international research on transfer in dense beds has focused stationary (stirred tank) systems, and there little to no information available the impact longitudinal or helical fins. Previous pilot plant scale experiments at TU Wien led...
