1. 1. Effects of Prolonged Electricity Supply Disruptions on Critical Entities

   Master-uppsats, Lunds universitet/Riskhantering (CI); Lunds universitet/Avdelningen för Riskhantering och Samhällssäkerhet

   Författare :André Hansson; [2023]
   Nyckelord :vital societal function; VSF; critical entity; CE; vital societal entity; VSE; critical infrastructure; CI; critical flow; prolonged outage; electricity supply disruption; preparedness; total defence; civil defence; civil preparedness; crisis preparedness; grey zone; critical entities resilience; CER; hybrid warfare; energy security; societal resilience; cascading effect; dependencies; interdependencies; long-term disruption; power outage; power disruption; consequences; outage; samhällsviktig verksamhet; kritisk infrastruktur; totalförsvar; beredskap; Technology and Engineering;

   Sammanfattning : This study investigates Swedish critical entities (CEs) ability to maintain function during up to three months of electricity supply disruptions. It also examines possible improvement measures, and how contextual cases (grey zone, heightened state of alert, war) influence CEs’ ability to maintain function during electricity supply disruptions.

3. 2. Framtidens användning av reservelverk inom eldistribution : En fallstudie på E.ON Energidistribution

   Master-uppsats, Linköpings universitet/Energisystem

   Författare :Gino Lauschke; Isabelle Olsson; [2023]
   Nyckelord :Reservelverk; Reservkraft; Dieselgeneratorer; Batterier; Bränsleceller; HVO; Eldistribution;

   Sammanfattning : Sweden has ambitious climate targets to achieve net zero emissions by 2045. One of the possiblesolutions to achieve this goal is electrification, and electricity use is expected to increase from today's 140 TWh to 170-282 TWh, according to the Swedish Energy Agency's different scenarios.

   Nyckelord :Battery storage; Electricity demand; Crisis preparedness; Socio-technical analysis; Electricity resilience; Household responsibility; Municipal responsibility; Knivsta kommun;

   Sammanfattning : This bachelor thesis aims to investigate household electricity supply and demand during a crisis. Both quantitative and qualitative aspects of crisis preparedness and household electricity demand are considered. LÄS MER

5. 4. Ray-tracing Based Investigations on the Deployment of RISs in Indoor Scenarios

   Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

   Författare :Swaroop Divya Sai Prem Nambala; Dexin Kong; [2023]
   Nyckelord :Reconfigurable intelligent surface; RIS; optimization; Ray-tracing; Mixed integer linear programming MILP ; Complex impulse response; Wireless Insite.; Technology and Engineering;

   Sammanfattning : Reconfigurable intelligence surface (RIS) is a promising candidate technology for future 6G wireless communication systems. In existing communication systems, the network operators are unable to control the propagation environment, which causes significant limitations on communication performance. LÄS MER

7. 5. Secrecy Capacity of Cooperative Transmission with Opportunistic Relaying Scheme

   Master-uppsats,

   Författare :Dhathri Pravallika Pasumarthi; [2022]
   Nyckelord :Cooperative Transmission; Opportunistic Relaying; Decode-and-Forward; Outage Probability; Secrecy Capacity; Fading.;

   Sammanfattning : The usage of wireless communication has increased over the past few years. Most wired communications are replaced by wireless communication for ease of use. Wireless communication transfers confidential information like personal information and credentials between two entities. LÄS MER
