  1. 1. Dynamics of Energy Systems - Methods of analysing technology change

    University dissertation from Environmental and Energy Systems Studies, Lund university

    Author : Lena Neij; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; [1999]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; evaluation; Energy research; market transformation; PV modules; wind power; experience curves; air-distribution; lighting; vintage models; sustainable energy; renewable energy; energy efficiency; Energy; energy system; Energiforskning; Environmental technology; pollution control; Miljöteknik; kontroll av utsläpp;

    Abstract : Technology change will have a central role in achieving a sustainable energy system. This calls for methods of analysing the dynamics of energy systems in view of technology change and policy instruments for effecting and accelerating technology change. In this thesis, such methods have been developed, applied, and assessed. READ MORE

  2. 2. Large Scale Solar Power Integration in Distribution Grids PV Modelling, Voltage Support and Aggregation Studies

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Afshin Samadi; KTH.; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Photovoltaic systems; PV system modelling; reactive power control; droop control; voltage sensitivity analysis; German Grid Codes; relative gain array RGA ; singular value decomposition SVD ; load modeling; system identification; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Long term supporting schemes for photovoltaic (PV) system installation have led to accommodating large numbers of PV systems within load pockets in distribution grids. High penetrations of PV systems can cause new technical challenges, such as voltage rise due to reverse power flow during light load and high PV generation conditions. READ MORE

  3. 3. Efficient Integration of Distributed Generation in Electricity Distribution Networks - Voltage Control and Network Design

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Ingmar Leisse; Lunds universitet.; Lund University.; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Distributed Generation; Coordinated Voltage Control; Electricity meter; PV; Wind Power; Distribution Network;

    Abstract : Distributed generation (DG), i.e. generation connected to the low and medium voltage distribution network (DN), has been increasing a lot during recent years. Thus the traditional assumption of a unidirectional power flow and a voltage decrease along the distribution feeders is no longer valid in all operation conditions. READ MORE

  4. 4. System analysis of a PV/T hybrid solar window

    University dissertation from Energy and Building Design, Lund University

    Author : Henrik Davidsson; Lunds universitet.; Lund University.; [2010]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PV T hybrid; Solar window; building integration; TRNSYS;

    Abstract : A building-integrated multifunctional PV/T solar window was suggested and developed by Andreas Fieber. The solar window is constructed of PV cells laminated on solar absorbers placed in a window behind the glazing. READ MORE

  5. 5. Evaluation of new active technology for low-energy houses

    University dissertation from Energy and Building Design, Lund University

    Author : Henrik Davidsson; Lunds universitet.; Lund University.; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hybrid ventilation; Low-quality heat; heat recovery; active house; solar window; PV T hybrid; building integration; TRNSYS;

    Abstract : Using energy at low-quality levels opens up new possibilities for low-energy houses. Low-quality energy can be heat at a temperature that is close to that of its surrounding, and can be used, for example, to pre-heat ventilation air or domestic hot water. READ MORE
