1. 21. Safety, Security, and Semantic Aspects of Equation-Based Object-Oriented Languages and Environments

   Författare :David Broman; Peter Fritzson; Henrik Nilsson; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Modeling; Simulation; Equation-Based; Object-Oriented; Modelica; Type System; Semantics; Language Safety; Secure Simulation; Computer science; Datavetenskap;

   Sammanfattning : During the last two decades, the interest for computer aided modeling and simulation of complex physical systems has witnessed a significant growth. The recent possibility to create acausal models, using components from different domains (e.g., electrical, mechanical, and hydraulic) enables new opportunities. LÄS MER

3. 22. Towards efficient modeling and simulation of district energy systems

   Författare :Johan Simonsson; Wolfgang Birk; Khalid Atta; Mika Ruusunen; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automatic Control; Reglerteknik;

   Sammanfattning : Dynamic simulation of district energy systems has an increased importance in the transition towards renewable energy sources, lower temperature district heating grids and waste heat recovery from industrial plants and data centers. However, a city-scale, automatically generated and updated simulator that can be used for the whole lifecycle of the plant remains a distant vision. LÄS MER

4. 23. Cyber-Physical Engineering of Distributed Automation Systems in Energy Domain

   Författare :Chen-Wei Yang; Valeriy Vyatkin; Evgeny Osipov; Nirmal Nair; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Dependable Communication and Computation Systems; Kommunikations- och beräkningssystem;

   Sammanfattning : The main focus of this thesis is in the domain of Energy Systems, specifically in the engi-neering of modern Smart Grid (SG) automation systems. The SG has been categorizedas a Cyber-Physical System (CPS), a complex system which exhibits tight integration between the cyber and the physical processes and their interactions in a networked envi-ronment.
