  1. 1. Production optimization for district heating : Short-term planning of district heating grid in Gävle, Sweden

    University essay from Mälardalens högskola/Akademin för ekonomi, samhälle och teknik; Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

    Author : Nicolas Lindgren; Karl Brogren; [2019]
    Keywords : Short-term planning; Optimization; District heating; Linear programming; Mixed integer non-linear programming; Branch and bound; Heat storage; MATLAB; TOMLAB;

    Abstract : Energy systems with a high portion of renewable energy from wind and solar power can suffer from fluctuations in production due to weak winds or cloudy weather, which may affect the electricity price. When producing heat and power in a combined heat and power plant, an additional heat storage tank can be used to store the heat surplus which is obtained when the power production is high, and the heat demand is low.

  2. 2. Improving energy security for individual households during outages : A simulation study for households in Sweden

    University essay from Uppsala universitet/Fasta tillståndets fysik

    Author : Amelie Bennich; [2019]
    Keywords : Off-grid; Energy security; Solar power; Energy storage; Outage;

    Abstract : In this study, it was investigated how individual households could manage security of supply during an outage by installing a local energy system that could operate independently from the electricity grid. By installing local renewable off-grid energy systems, households could guarantee an uninterrupted supply of energy even during an outage on the electricity grid, while also increasing their energy autonomy during normal circumstances.

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Eveline Haugaard; [2019]
    Keywords : Operational energy use; Climate impact; LCA methodology; Environmental evaluation of energy;

    Abstract : In 2017, the Swedish Parliament voted for a climate aim which says Sweden should achieve zero net emissions of greenhouse gases in 2045. The building and construction sector is one of the sectors that needs to reduce it’s climate impact. As of 2016, 12. READ MORE

  4. 4. FEASIBILITY OF USING LITHIUM-ION BATTERIES FOR LOAD SHIFTING : A thesis study that analyze the performance and economic feasibilities for an air compressor with a battery system

    University essay from Mälardalens högskola/Akademin för ekonomi, samhälle och teknik; Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

    Author : Sebastian Zainali; Sofia Osbeck; [2019]
    Keywords : Battery; energy demand; load shifting; electricity price; state of charge; degradation;

    Abstract : The electricity price changes depending on the time of the day in most countries. In Sweden there is a spot price that changes every hour while China uses Time of Use (ToU) tariff. To avoid the most expensive hours this degree project investigates the feasibility of using lithium- ion batteries to shift the load of an industrial air compressor. READ MORE

  5. 5. 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
