  1. 1. Wind power in thermal power systems

    Författare :Lisa Göransson; [2008]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; integration; wind power; variation moderator; PHEV; storage;

    Sammanfattning : AbstractWind power is a key technology in the effort to transform the power system in order to reduce its climate impact. However, the ability of wind power to reduce CO2-emissions depends on the properties of the power system. LÄS MER

  2. 2. Possibilities of using thermal mass in buildings to save energy, cut power consumption peaks and increase the thermal comfort

    Detta är en avhandling från Division of Building Materials, LTH, Lund University

    Författare :Jonathan Karlsson; [2012]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; concrete; aggregates; heat capacity; thermal properties; thermal conductivity; thermal inertia; thermal mass; time constant; Energy storage;

    Sammanfattning : The aim of this project was to generate knowledge to enable us to take advantage of heat storage in heavy building structures with regard to as energy savings, better thermal indoor climate, and reduced peak powers. This could include buildings that can function without energy input during cold periods, buildings that give a robust indoor climate without installed cooling, and buildings with good thermal comfort also in case of higher outdoor temperatures resulting from global warming.

  3. 3. Cooling Strategies for Wave Power Conversion Systems

    Detta är en avhandling från Division of Building Materials, LTH, Lund University

    Författare :Antoine Baudoin; Cecilia Boström; Anne Blavette; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wave power; power conversion system; thermal management; power elctronics; passive cooling; natural convection.;

    Sammanfattning : The Division for Electricity of Uppsala University is developing a wave power concept. The energy of the ocean waves is harvested with wave energy converters, consisting of one buoy and one linear generator. The units are connected in a submerged substation. The mechanical design is kept as simple as possible to ensure reliability. LÄS MER

    Sammanfattning : Energy consumption in the world has increased continuously due to a growing population and increased energy consumption per capita. Moreover, the largest part of consumed energy still comes from fossil sources which in 2016 was more than 130 PWh. LÄS MER

  5. 5. Thermal Modelling of Power Modules in a Hybrid Vehicle Application

    Detta är en avhandling från KTH Royal Institute of Technology

    Författare :Jonas Ottosson; [2013]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Power Module; Thermal Modelling; Electro-Thermal Simulations; Reliability; Cooling requirements;

    Sammanfattning : Hybrid electric and full electric vehicles have attracted growing attention during the last decade. This is a consequence of several factors, such as growing environmental concerns, increasing oil prices and a strive for oil independency. LÄS MER
