1. 21. An Energy Efficient Radio Base Station

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

   Författare :Lakshmi Prasad; [2018]
   Nyckelord :Technology and Engineering;

   Sammanfattning : The mobile telecommunication network is growing year after year and it will soon move into the high speed 5G and Internet of Things technology. These new technologies will improve the throughput and data connectivity and due to that the energy consumption in radio and digital units may increase in a Radio Base Station (RBS). LÄS MER

3. 22. Investigating the energy demand and supply of a residential neighborhood in Malmö

   Master-uppsats, Lunds universitet/Avdelningen för Energi och byggnadsdesign; Lunds universitet/Institutionen för arkitektur och byggd miljö

   Författare :Tianqi Wang; [2018]
   Nyckelord :Building energy performance; Solar energy; Micro wind turbine; Residential buildings.; Technology and Engineering;

   Sammanfattning : Facing the climate change and the energy crisis, the governments are taking steps to reduce the energy use and enhance the integration of renewable energy installations. Built environment is attributed to 40% of the global energy use, and the literature indicates that integrating the local renewable energy sources to the grid and meanwhile renovating the buildings can significantly improve the energy performance of the building sector.

4. 23. Grid impact study of frequency regulation with EVs

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

   Författare :Emma Blomgren; [2018]
   Nyckelord :Electric vehicles EVs ; grid impact; ancillary services; frequency regulation; FCR-N; vehicle-to-grid V2G ; voltage; reactive power; load profile; Technology and Engineering;

   Sammanfattning : The ongoing grid paradigm shift has resulted in synchronous generators currently being phased out. As the generators have been providing ancillary services, such as frequency control regulation, this means that new technologies to perform ancillary services need to be developed and evaluated.

5. 24. Concentrating Collector for Torsång District Heating System

   Master-uppsats, Högskolan Dalarna/Energiteknik

   Författare :Artem Filatov; [2018]
   Nyckelord :Concentrating solar collector; Absolicon; Arcon; Heatstore; flat-plate collector; Borlange; Torsang; Sweden; parabolic trough; thermal collector;

   Sammanfattning : In this thesis report for Dalarna University in Borlange and Absolicon company the study of a possibility to add an array of concentrating solar collectors to a Torsång district heating system was done. The whole idea of this work was to make a simulation of this kind of system, trying to get 15-20% of solar fraction, and make an economical evaluation. LÄS MER
