  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.

  3. 3. Power System Protection Modelling with IEC 61850 and IEC 61499

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Francisco De Lima; [2019]
    Keywords : ;

    Abstract : The nature of the power system is changing; what was once a clearlydened generation-transmission-distribution-consumer power ow is nowshifting towards a distributed infrastructure, with great amounts of variablerenewable sources in the system. The penetration of alternative energieslike solar and wind have represented a game changer for the electricpower industry, diminishing the traditional dominance of fossil fuel basedsources, and moving towards a more renewable mixture.

  4. 4. A multi-criteria GIS analysis for siting of utility-scale photovoltaic solar plants in county Kilkenny, Ireland

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Ingrid Piirisaar; [2019]
    Keywords : Geography; GIS; MCDM; solar plants; site suitability; Ireland; Earth and Environmental Sciences;

    Abstract : Renewable energy is the keyword for energy industry sector in the world today. Solar energy has a huge potential, able to fulfill increasing energy demand and growing its share of energy sector. Republic of Ireland has one of the lowest solar energy deployment rates in Europe, although climatic conditions have been proved to be acceptable. READ MORE

  5. 5. Introducing a central receiver system for industrial high-temperature process heat applications : A techno-economic case study of a large-scale CST plant system in a South African manganese sinter plant

    University essay from KTH/Kraft- och värmeteknologi; KTH/Kraft- och värmeteknologi

    Author : Maria Hallberg; Elin Hallme; [2019]
    Keywords : Solar energy; concentrating solar thermal; CST; central receiver system; CR; HelioPod; high-temperature process heat; manganese; business case; Solenergi; koncentrerad termisk solvärme; CST; soltorn; HelioPod; högtempererad processvärme; mangan; affärsmodell;

    Abstract : The objective of this thesis was to investigate the potential for introducing a concentrating solar thermal (CST) central receiver plant system based on flexible heliostats - HelioPods - to provide high-temperature process heat in industrial applications. A CST plant system was designed in MATLAB, optically simulated for three design days in the ray-tracing software Tonatiuh and further analyzed in MATLAB by interpolating the results for each hour of the year.
