1. 11. Water born cooling of closed greenhouses : An enclosed vertical water curtain cooling system

   Magister-uppsats, Högskolan Dalarna/Institutionen för information och teknik

   Författare :Ahmad Kamal; [2022]
   Nyckelord :Greenhouses; Water born cooling; Enclosed water curtain; radiative cooling; Surplus heat energy;

   Sammanfattning : The greenhouses play a key role in food sustainable production, the purpose of the greenhouses is to make an artificial suitable environment to grow different kinds of plants. The cost of energy used in the greenhouses to ensure the optimum temperature, humidity, and CO2 concentration, makes up a large part of the final cost of food. LÄS MER

3. 12. Randomized heuristic scheduling of electrical distribution network maintenance in spatially clustered balanced zones

   Master-uppsats, KTH/Geoinformatik

   Författare :Carolina Offenbacher; Ellen Thornström; [2022]
   Nyckelord :Capacitated Vehicle Routing Problem; Electrical distribution network; Heuristic algorithm; Scheduling; Handelsresandeproblemet; Eldistributionsnätverk; Heurustik algortim; Schemaläggning;

   Sammanfattning : Reliable electricity distribution systems are crucial; hence, the maintenance of such systems is highly important, and in Sweden strictly regulated. Poorly planned maintenance scheduling leads unnecessary driving which contributes to increased emissions and costs. LÄS MER

4. 13. Evaluation of improved Airflow in TM-102/II-DC

   M1-uppsats, Mälardalens universitet/Akademin för innovation, design och teknik

   Författare :Claudia Kazemi; [2022]
   Nyckelord :Airflow systems for electronics; thermal management; telecommunication equipment; airflow resistance; cooling of electronics.; Luftflödessystem för elektronik; termisk hantering; telekommunikations applikationer; luftflödesmotstånd; kylning av elektronik;

   Sammanfattning : Within the company Infinera, there is a need for an improved thermal design of an existing chassis product for use in telecommunications for distribution of services within the Edge & Metro network. To enable an optimized airflow design of the chassis, there is a need of analyzingdifferent simulation cases performed in FloTHERM. LÄS MER

5. 14. Power systems with local PV-generation and battery storage for peak shaving to provide flexibility services to the utility grid

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära

   Författare :Vincent Jansson; [2022]
   Nyckelord :Peak shaving; power peaks; flexibility services; flexibility markets;

   Sammanfattning : Due to the increased demand for electricity in recent years and the estimated demand in the future it has become clear that the capacity of the Swedish electrical grid is insufficient, and the grid is not able deliver the amount of power that is demanded by the market. The crucial points in the grid where the grid capacity is insufficient could be several. LÄS MER

7. 15. Congestion Management of EV Charging in Distribution Networks

   Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automation

   Författare :Adam Rosandell; [2022]
   Nyckelord :Technology and Engineering;

   Sammanfattning : The societal integration of electric vehicles (EVs) imposes several challenges on the electrical grid, where congestion and overcurrents through related components are of focus for this thesis. Active network management through control systems is one flexible solution to this problem, and in the project Active Network Management for All (ANM4L), a congestion management algorithm utilizing PI controllers has been developed.
