  1. 1. Protection for Multiterminal HVDC Grids - A Digital Contribution

    Författare :Ilka Jahn; Staffan Norrga; Hans-Peter Nee; Dirk Westermann; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HVDC transmission; power system protection; IED; real-time systems; test bench; field programmable gate array; open-source hardware; open-source software; power engineering education; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : The aim of this thesis is to (1) enhance understanding of mechanisms that are important for the protection of high-voltage direct-current (HVDC) grids, and (2) suggest possible technical solutions. To that end, digital technologies were used both in simulation, as well as in a laboratory environment. LÄS MER

  3. 2. Benefits of Coordinating Plug-In Electric Vehicles in Electric Power Systems : Through Market Prices and Use-of-System Network Charges

    Författare :Ilan Momber; Lennart Söder; Tomás Gómez San Román; José Villar Collado; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electric Vehicles; Power Systems; Optimization; Elektrische Voertuigen; Energiesystemen; Optimalisatie; Elbilarna; Elkraftsystem; Optimering; Vehiculos Electricos; Sistemas de Potencia; Optimización; Electrical Engineering; Elektro- och systemteknik; Economics; Nationalekonomi; Industriell ekonomi och organisation; Industrial Engineering and Management; Energy Technology; Energiteknik; Transportvetenskap; Transport Science;

    Sammanfattning : Both electric power systems and the transportation sector are essential constituents to modern life, enhancing social welfare, enabling economic prosperity and ultimately providing well-being to the people. However, to mitigate adverse climatological effects of emitting greenhouse gases, a rigorous de-carbonization of both industries has been set on the political agenda in many parts of the world.

  4. 3. Denk- und Kommunikationsansätze zur Bewertung des Nachhaltigen Bauens und Wohnens anhang der Ökologischen Wohnsiedlung Flintenbreire in Lübeck

    Författare :Holger Wallbaum; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Resource; Ecology; Sustainability; Settlment; Indicator;

    Sammanfattning : It is the aim of the present study to detect the reasons for these grievances, taking as an example the new Ecological Housing Estate Flintenbreite, and to demonstrate alternative solutions. For this purpose, different concepts of assessment are employed which meet the requirements of a full life cycle analysis. LÄS MER

  5. 4. Dialogues on the Net - Power structures in asynchronous discussions in the context of a web based teacher training course

    Författare :Annette Johnsson; Utbildningsvetenskap; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; minority; cultural background; sex; ethnicity; gender; age; socio-economic; dialogicity; web based; computer based; CMC; net based; asynchronous; CSCL; teacher education; power structures; dialogues; Group work; team work; symbolic capital; group work;

    Sammanfattning : The general aim of this thesis is to investigate the interaction processes that occur in group dialogues when teacher students work in small groups, using net based asynchronous dialogues to solve a problem in the area of environmental sustainability. More specifically, the interest is to determine whether students’ net based dialogues give rise to patterns of dominance/subordination similar to those observed in face-to-face situations. LÄS MER

  7. 5. Aggregation of Plug-in Electric Vehicles in Power Systems for Primary Frequency Control

    Författare :Seyedmahdi Izadkhast; Mehrdad Ghandhari; Garcia-Gonzalez Pablo; Frias Pablo; Ignacio Egido Cortés; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aggregation; Plug-in Electric Vehicles; Primary Frequency Control; Aggregeren; Plug-in Elektrische Voertuigen; Primaire Reserve; Laddbara Bilar; Elnätet; Primär Frekvensreglering; Agregación; Vehículos Eléctricos Enchufables PEVs ; Control Primario de Frecuencia PFC ; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : The number of plug-in electric vehicles (PEVs) is likely to increase in the near future and these vehicles will probably be connected to the electric grid most of the day time. PEVs are interesting options to provide a wide variety of services such as primary frequency control (PFC), because they are able to quickly control their active power using electronic power converters.
