    Abstract : Power production has a vital role in the functioning of society and will have a major part in the future of environmental and economical sustainability. Therefore, efficiencies of power plants are always a subject to improvements in order to utilise resources as efficient as possible. READ MORE

  3. 3. Evaluating the Impact of Altered Electricity Systems

    University essay from Lunds universitet/Miljö- och energisystem

    Author : Carolin Bangay; [2019]
    Keywords : Linear Programming; Transmission; Energy Systems; Green House Gas; Emissions; Electricity Systems; Modelling.; Technology and Engineering;

    Abstract : In the light of the importance of climate change and the emissions that have induced it, the ability to calculate the effect on emissions by changing transmission capacity is vital. A model to perform such indicative calculations is developed in this thesis. READ MORE

  4. 4. ”Varför hamnar allting där nere?” : lokalinvånares syn på vattenkraftsetableringen i Lilla Lule älv

    University essay from SLU/Dept. of Urban and Rural Development

    Author : Izabel Nordlund; [2018]
    Keywords : vattenkraft; lokalinvånare; landsbygd; Lilla Lule älv; Letsi; industriell kolonisation;

    Abstract : Vattenkraften utgör en stor del av Sveriges elproduktion och det är en stabil elförsörjning. Stora delar av produktionen kommer från Luleälven som började byggas ut redan i början på 1900-talet. För att ta reda på hur lokalinvånare ser på vattenkraftetableringen har fyra informanter som levt kring älven intervjuats. READ MORE

  5. 5. A Model-Predictive-Control Based Smart-Grid Aggregator

    University essay from KTH/Optimeringslära och systemteori

    Author : Amanda Paulus; [2018]
    Keywords : ;

    Abstract : Intermittent energy source usage, such as solar and wind power, is continuously increasing. Intermittent energy sources are highly dependent on prevailing weather conditions, resulting in stochastic electricity generation. The expected stochasticity in electricity generation will cause issues for the current power grid. READ MORE
