1. 16. Start of a new design method for a competitive Small Modular Reactor (SMR) adaptable to future uses

   Master-uppsats, KTH/Skolan för teknikvetenskap (SCI)

   Författare :Baptiste Mazurié; [2023]
   Nyckelord :Requirement modelling; Cyber-physical systems; Small Modular Reactor SMR ; Systems Engineering; CRML;

   Sammanfattning : As cyber-physical systems become increasingly complex, the management and verification of requirements during design is essential. A new language called CRML (Common Requirement Modelling Language) has been created during the European EMBrACE project to formalize realistic dynamical requirements, but a method for representing these requirements and a framework for using them as a design aid must be defined to ease appropriation by engineers.

3. 17. Modelling and Simulation of Hydrogen Electrolyzers for Power System Applications

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Javier Vinuelas Ferrando; [2023]
   Nyckelord :;

   Sammanfattning : The rapid increase in the share of intermittent renewables in the energy mix is exacerbating the complexity of the grid stability. To facilitate the inclusion of these green technologies and achieve the climate targets set by the EU, the generation and storage of hydrogen through electrolysis may be crucial. LÄS MER

4. 18. Short-horizon Prediction of Indoor Temperature using Low-Order Thermal Networks : A case study of thermal models for heat-system control applications

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Jonas Cederberg; [2023]

   Sammanfattning : Optimizing and controlling the heating systems in buildings is one way to decrease their load on the power grid, as well as introduce load flexibility to be used in Demand Response (DR) applications. A requirement in occupied buildings is that the thermal comfort of the residents is guaranteed, making the optimization of heating systems a constrained problem with respect to indoor temperature.
