  1. 1. Dispatch Optimizer for Concentrated Solar Power Plants

    Master-uppsats, Uppsala universitet/Byggteknik och byggd miljö

    Författare :Gilda Miranda; [2020]
    Nyckelord :Concentrated Solar Power; optimization; dispatch; thermal energy storage;

    Sammanfattning : Concentrating solar power (CSP) plant is a promising technology that exploits direct normal irradiation (DNI) from the sun to be converted into thermal energy in the solar field. One of the advantages of CSP technology is the possibility to store thermal energy in thermal energy storage (TES) for later production of electricity. LÄS MER

  2. 2. Outdoor Stability Testing of Printed Organic Solar Cells for Indoor Applications

    Master-uppsats, Karlstads universitet

    Författare :Cathrine Hekkala; [2020]
    Nyckelord :Solar energy; organic solar cell; printed; flexible; degradation; outdoor; indoor;

    Sammanfattning : Renewable energy is required for a sustainable future and one way to meet this is with organic solar cells (OSCs). The OSC can be easily manufactured at a low cost, be lightweight and be used on flexible surfaces. LÄS MER

  3. 3. A study of the stability of vitamin 25[OH]D2 and 25[OH]D3

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för kemi och biomedicin (KOB)

    Författare :Anna Kellström; [2020]
    Nyckelord :Vitamin D; 25-hydroxyvitamin D; pre-analytical relevance; HPLC-MS MS; stable; freeze-thaw cycles; light sensitivity; quality assurance;

    Sammanfattning : During the industrialization of the 19th century the negative health effects of vitamin D was discovered as children in the cities developed osteomalacia or more commonly known as rickets caused by vitamin D deficiency. Vitamin D is produced in the skin from 7-dehydrocholesterol during sun-exposure and enhances intestinal phosphor and calcium absorption thus enhancing the bone remodeling process. LÄS MER

  4. 4. Solar access potential affected by urban planning and building design – A parametric study in the urban context

    Master-uppsats, Lunds universitet/Energi och ByggnadsDesign; Lunds universitet/Institutionen för arkitektur och byggd miljö

    Författare :Yuncong Li; Yiting Tian; [2020]
    Nyckelord :Daylight; urban planning; solar access potential; sun hours; vertical sky component; vertical daylight illuminance; solar irradiation; parametric analysis; Berlin; Copenhagen; Hong Kong; Arts and Architecture; Technology and Engineering;

    Sammanfattning : In the initial stage of planning, considering the solar impact of urban layout on the building can effectively avoid some irreversible design issues, improve the indoor environment, and reduce energy demand. The typical architectural models of three representative cities (Copenhagen, Berlin and Hong Kong) were selected as the analysis cases in this study. LÄS MER

  5. 5. Pre-feasibility study of V2G system in the micro-grid of St. Martine Island, Bangladesh.

    Magister-uppsats, Uppsala universitet/Elektricitetslära

    Författare :Md Abu Raihan Chowdhury; [2020]
    Nyckelord :Vehicle to grid; Micro-grid; Electric Vehicle; Simulink Simscape; Feasibility analysis.;

    Sammanfattning : The goal of the study was to evaluate the potential of the V2G system as a solution to peak load leveling and integrating more renewable energy in the microgrid of St. Martine Island. Simulink Simscape software was used to model a microgrid with a V2G system for the small community of the Island. LÄS MER
