5. 4. The Operational Strategy Optimization of Distributed Energy System Based on MATLAB : A case study in Northeast China

   Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

   Författare :Yujun Han; [2023]
   Nyckelord :Distributed Energy System; CCHP; operational strategy; Distribuerat energisystem; CCHP; operativ strategi;

   Sammanfattning : China is the largest energy consumer worldwide, with a fast-growing rate. But the energy and environmental problems brought by its unbalanced energy structure and low energy efficiency restrict the sustainable development of China. The Distributed Energy System (DES) is one of the internationally recognized solutions to the problems. LÄS MER

7. 5. Hydrogen storage systems : Methodology and model development for hydrogen storage systems performance evaluation based on a transient thermodynamic approach

   Master-uppsats, Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

   Författare :Kreshnik Margaritari; [2023]
   Nyckelord :Hydrogen; Hydrogen storage system; Hydrogen filling process; Hydrogen storage system operation; Hydrogen storage system design; Hydrogen fast filling; Hydrogen tank modelling;

   Sammanfattning : The overall performance of a hydrogen storage system can be affected by various parameters, such as operation and design parameters, but also by the state of the hydrogen contained inside the storage tanks. In this work, a methodology is developed to evaluate the state of the hydrogen during the filling process and its impact on the overall system performance under variable operation conditions and design parameters.
