  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.

  5. 5. 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.
