2. 11. Voltage Support of Transmission Grids Using Resources Located in the Underlying Lower Voltage Networks : Unlocking the Potential of Distributed Generation Reactive Power Capabilities

   Author : Stefan Stanković; Lennart Söder; Andrew Keane; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reactive power support; voltage control; voltage stability; reactive power planning; inverter-based generation; active distribution networks; Electrical Engineering; Elektro- och systemteknik;

   Abstract : The path to sustainable, fossil-free future leads to inevitable energy transition towards renewable energy sources. A part of this transition includes replacement of conventional transmission system connected power plants with distributed renewables plants such as wind power. READ MORE

4. 12. Modelling interactions between distributed energy technologies and the centralised electricity supply system

   Author : Joel Goop; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy systems modelling; variable renewables; power systems; distributed generation; demand response; electricity storage;

   Abstract : Renewable electricity generators, such as solar photovoltaics (PVs), and variation management technologies, such as battery storage and demand response (DR) systems, can be deployed in a distributed fashion, which can benefit the overall system. Such distributed energy technologies interact with and influence the centralised generation and transmission systems. READ MORE

5. 13. Accelerating Distributed Storage in Heterogeneous Settings

   Author : Waleed Reda; Dejan Kostic; Peter Van Roy; Marco Chiesa; Adam Morrison; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Distributed storage; File systems; Hardware offload; Persistent memory; Distribuerad lagring; Dilsystem; Maskinvaruavlastning; Beständigt minne; Computer Science; Datalogi;

   Abstract : Heterogeneity in cloud environments is a fact of life—from workload skews and network path changes, to the diversity of server hardware components, these are all factors that impact the performance of distributed storage. In this dissertation, we identify that heterogeneity can in fact be one of the primary causes of service degradation for storage systems. READ MORE

6. 14. Large-scale Runoff Generation and Routing : Efficient Parameterisation using High-resolution Topography and Hydrography

   Author : Lebing Gong; Sven Halldin; C.-Y. Xu; Allan Rodhe; Thorsten Wagener; Uppsala universitet; []

   Abstract : Water has always had a controlling influence on the earth’s evolution. Understanding and modelling the large-scale hydrological cycle is important for climate prediction and water-resources studies. READ MORE

7. 15. Demand response and distributed solar generation in the Swedish residential sector - A techno-economic evaluation

   Author : Emil Nyholm; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Demand response; Distributed solar generation;

   Abstract : There is an urgent need to transform the electricity system so as to reduce greenhouse gas emissions. Among the possible pathways for such a transformation, the demand side of the electricity system is likely to take a more active role than it has historically. READ MORE
