2. 1. Metadata Management in Multi-Grids and Multi-Clouds

   Author : Daniel Espling; Erik Elmroth; Erwin Laure; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; grid computing; cloud computing; accounting; billing; metadata; monitoring; structure; fairshare; scheduling; federated; Computer Science; datalogi;

   Abstract : Grid computing and cloud computing are two related paradigms used to access and use vast amounts of computational resources. The resources are often owned and managed by a third party, relieving the users from the costs and burdens of acquiring and managing a considerably large infrastructure themselves. READ MORE

4. 2. Enabling Technologies for Management of Distributed Computing Infrastructures

   Author : Daniel Espling; Erik Elmroth; Rizos Sakellariou; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; grid computing; cloud computing; accounting; billing; contextualization; monitoring; structure; fairshare; scheduling; federated; Computer Science; datalogi;

   Abstract : Computing infrastructures offer remote access to computing power that can be employed, e.g., to solve complex mathematical problems or to host computational services that need to be online and accessible at all times. READ MORE

5. 3. Passive Island Detection of Microgrid by Grid Forming Inverter

   Author : Shoaib Salim Inamdar; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; microgrid; passive island detection; Grid forming; rotor angle deviation; non-detection zone; inertia; virtual synchronous machine; voltage vector shift.;

   Abstract : The supply reliability of a local grid will be improved if the local grid is managed as a microgrid, with the ability to operate in island mode when the main grid is temporarily unavailable. This thesis focuses on microgrids powered by inverter-based resources (IBRs), one or several of which need to be equipped with grid forming (GFM) capability for establishing and controlling the voltage and frequency of the microgrid during island operation.

6. 4. Expansion Governance of the Integrated North Seas Offshore Grid

   Author : João Gorenstein Dedecca; Paulien M. Herder; Rudi A. Hakvoort; Amineh Ghorbani; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Union; expansion planning; governance; HVDC; myopic optimization; North Seas; offshore grid; offshore wind; simulation;

   Abstract : The expansion of offshore power transmission and generation in the North Seas of Europe is accelerating rapidly. This is due to several drivers, including the decarbonization and reform of the European power system, and innovations in offshore wind and high-voltage direct current transmission. READ MORE

7. 5. Sensitivity and Uncertainty Analysis Methods : with Applications to a Road Traffic Emission Model

   Author : Olle Eriksson; Stig Danielsson; Rolf Sundberg; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Emission; Grid; Model; Pollutant; Response surface; Road traffic; Sensitivity analysis; Simulation; Uncertainty analysis; Avgaser; Vägtrafik; Miljöaspekter; Statistics; Statistik;

   Abstract : There is always a need to study the properties of complex input–output systems, properties that may be very difficult to determine. Two such properties are the output’s sensitivity to changes in the inputs and the output’s uncertainty if the inputs are uncertain. READ MORE
