  1. 16. Vehicle to Home and Vehicle to Grid : a study and modeling of the technical system when charging and discharging electric vehicles for households with PV systems

    University essay from Uppsala universitet/Elektricitetslära

    Author : Christine Timm; [2023]
    Keywords : electric vehilce; EV; bidirectional charging; smart charging; smart charging algorithms; optimization; PV;

    Abstract : As the world undertakes global climate goals to lower the emissions of greenhouse gases, more renewable energy sources are introduced in the electrical energy system, and fossil fuel driven combustion engines aims to be replaced by electric vehicles. New problems connected to the transition such as voltage fluctuations, production and consumption mismatch and high peak loads, requires new solutions. READ MORE

  3. 17. Techno-economic assessment of off-grid PV systems in Eritrean buildings : A case study about apartment buildings in Asmara

    University essay from Högskolan i Halmstad/Akademin för företagande, innovation och hållbarhet

    Author : Adonay Yosief; [2023]
    Keywords : Eritrea; PV; Asmara; Battery; Hydrogen; Homer Pro;

    Abstract : Eritrea is experiencing difficulties as a result of its low rate of electricity, together with its expanding population and the significance of green energy in today's world. Due to poor infrastructure and capacity, Asmara's electricity grid is well known for being unreliable, with frequent power outages and load shedding. READ MORE

  4. 18. Grid stability evaluation and techno-economic analysis of shared solar applications within a Swedish energy community.

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Hugo Holsti Heijbel; [2023]
    Keywords : Energy communities; Renewable energy; Local sharing; Solar penetration; Grid stability analysis; Energigemenskaper; Förnybar energi; Lokal delning; Solpenetration; Nätstabilitetsanalys;

    Abstract : The joint European electricity production in 2022 was 2.9 PWh where 34.3% of the electricity came from sources of natural gas and coal. However, to be able to achieve the goals of the Paris agreement, greenhouse gas emissions must peak before 2025 and thus call for a rapid decarbonatization. READ MORE

  5. 19. Developing an Ar milling process to improve the contact quality to InAs nanowires

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Fasta tillståndets fysik

    Author : Chris Mkolongo; [2023]
    Keywords : InAs nanowires; Argon milling; Technology and Engineering;

    Abstract : The aim of this work was to develop a stable and reproducible argon milling process for InAs nanowires to remove the native oxide layer that increases electrical resistance. This was done by identifying a few milling parameters and studying them in relation to the milling rate of silicon dioxide (SiO2). READ MORE

  6. 20. Comparative Analysis of Modern Energy Systems for Ice Rinks

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Pendar Hemati; [2023]
    Keywords : Ice rinks; refrigeration; heat recovery; CO2; ammonia; propane; Pistas de hielo; refrigeración; recuperación de calor; CO2; amoníaco; propano;

    Abstract : Ice rinks are highly energy-intensive commercial buildings with an average annual energy consumption of 1,000 MWh, most of it being used to cover the simultaneous heating and cooling demands. The aim of this thesis is to find the most energy efficient energy system for ice rinks by evaluating different system modifications and refrigerants. READ MORE
