Thermocline thermal storage modeling towards its predictive optimal management

چکیده
The increasing penetration of renewable energies brings into sharp relief the potential thermal storages, particularly in multi-energy networks. Indeed, they offer low storage cost without environmental concerns. But since physical phenomena during operation thermocline storages are complex, associated models come with long calculation times. Consequently, their integration within live management networks is challenging at current time. Hence, this work proposes meta modeling based on simulation data from previous as an alternative to modeling. developed model compared three different varying complexity. Compared a typical same spatial dimension, time reduced by factor up 1000 while losses well internal temperature distribution estimations equally provided. In experimental validation four configurations capacities between 450 and 2900 kWhth, normalized root mean square deviation lower than 3% results observed. Moreover, often fail depict real-life behavior for example due manufacturing defects or highly dimension-dependent like flow channeling. order overcome practical challenge, construction use basis existing successfully demonstrated experiments below 4%.

Thermal Modeling of Hybrid Storage Clusters
There is a lack of thermal models for storage clusters; most existing thermal models do not take into account the utilization of hard drives (HDDs) and solid state disks (SSDs). To address this problem, we build a thermal model for hybrid storage clusters that are comprised of HDDs and SSDs. We start this study by generating the thermal profiles of hard drives and solid state disks. The profili...
متن کاملTowards Optimal Scalability in Predictive Video Coding
We propose a method for eecient SNR scalabil-ity in predictive video coding which overcomes the known fundamental diiculties due to the prediction loop. The method is generally applicable to any scal-able predictive coder but a special emphasis is given in this paper to standard DCT-based video compression. The compression eeciency of the enhancement-layer is substantially improved by casting t...
متن کاملPosition Paper: Towards Comprehensible Predictive Modeling
Predictive modeling applications have a number of concerns. While predictive accuracy is often the primary concern, other issues such as efficiency and robustness are often considered. It is my position that comprehensibility is another concern in predictive modeling applications, and is often an important one. However, without an understanding of comprehensibility in predictive modeling, it is...
