  1. 1. Conservation Voltage Reduction i Sverige - en simuleringsstudie

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

    Författare :Kewin Erichsen; Stefan Viklund; [2019]
    Nyckelord :Conservation Voltage Reduction; Distribution grid; Energy conservation; Load modelling; OpenDSS; Peak shaving; Simulation; Voltage regulation; Technology and Engineering;

    Sammanfattning : Conservation Voltage Reduction, or short just CVR, is a technique in which the reference voltage at a substation is lowered a few percent in order to conserve energy and decrease peak demand in an electrical distribution grid. Thus, CVR can be used when the energy or power capacity can't be satisfied by the feeding grid. LÄS MER

  3. 2. Krig och fred -standardisering, rutiner och lärande

    Kandidat-uppsats, Lunds universitet/Företagsekonomiska institutionen

    Författare :Marcus Anneroth; Josephine Dencker; Stefan Pettersson; [2014]
    Nyckelord :Standardization; routines; learning; Business and Economics;

    Sammanfattning : The purpose for which the study was conducted was to investigate firm-specific advantages of standardization, and how standardization routines optimized and changing as intra organizational learning. The study was conducted as a qualitative case study where the pattern matching method is used to compare and analyse the collected data against a pre-constructed theoretical framework. LÄS MER

  4. 3. Undersökning av luftkvaliteten vid småskalig biobränsleförbränning i två kommuner med modellsystemet VEDAIR

    Uppsats för yrkesexamina på grundnivå, Institutionen för geovetenskaper

    Författare :Stefan Andersson; [2007]
    Nyckelord :VEDAIR; modell; SMHI; luftkvalitet; luftkvalité; PM10; partiklar; emission; spridning; dispersion; halter; luftföroreningar; utsläpp; Vänersborg; Gnosjö; biobränsle; eldning; vedeldning; förbränning; miljökvalitetsnormer; utvärderingströskel; SIMAIR; gaussisk plymmodell; validering;

    Sammanfattning : An Internet application, VEDAIR, for estimation of air quality in regions with small-scale combustion of bio fuel has been developed by Swedish Meteorological and Hydrological Institute with financing from Swedish Energy Agency and Swedish Environmental Protection Agency. The model contains user interface and a coupled model concept where concentrations of atmospheric pollutions are calculated for regional, urban and local contributions. LÄS MER
