  1. 21. Possibilities with Stirling Engine and High Temperature Thermal Energy Storage in Multi-Energy Carrier System : An analysis of key factors influencing techno-economic perspective of Stirling engine and high-temperature thermal energy storage

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

    Author : Martin Myska; [2021]
    Keywords : Stirling engine; High-temperature thermal energy storage; Linear optimization; Photovoltaics; Time of Use; Renewable energy; Load shifting; Self-consumption; Power grid;

    Abstract : Small and medium-scale companies are trying to minimise their carbon footprint and improve their cash flow, renewable installations are increasing all over the Europe and are expected to do so in following years. However, their dependency on the weather cause pressure on matching the production with demand. READ MORE

  3. 22. Pasta, Pancakes and Power Peaks

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Sebastian Ljungman; [2021]
    Keywords : ;

    Abstract : Uppsala is growing, and with it the need for electricity. During certain times of day, the Uppsala electricity grid is struggling to meet power demands, and so it is desirable to decrease the amount of power consumed during these peaks. READ MORE

  4. 23. Optical characterisation of AAO/CsPbBr3 perovskite nanocomposites

    University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Author : Klára Nováková; [2021]
    Keywords : perovskite; scintillator; optoelectronics; semiconductor; X-ray detection; Physics and Astronomy;

    Abstract : Direct bandgap metal lead halide perovskites offer promising optoelectronic properties desirable in a wide range of applications including photodetection. However, the incomplete and poor understanding of the photophysical processes taking place in these materials, along with their poor stability, is the bottleneck for optimisation and further development of metal halide perovskite devices.

  5. 24. Determining and analysing production losses due to ice on wind turbines using SCADA data

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Oscar Felding; [2021]
    Keywords : Wind turbines; ice accretion; ice losses; SCADA; cold climate; Vindturbin; ispåbyggnad; isförluster; SCADA-data; kallt klimat;

    Abstract : Wind turbines are becoming a more common sight and a more important part in the power grid. The benefits are mainly that wind energy is a renewable energy source and a single wind turbine can produce enough electricity to cover several households’ annual electricity need and not producing carbon dioxide as a rest product.

  6. 25. Local energy system - Comparing direct current (LVDC) and alternating current (LVAC)

    University essay from Lunds universitet/Industriell elektroteknik och automation

    Author : Markus Alm; [2020]
    Keywords : Local energy system; LVDC; Technology and Engineering;

    Abstract : This thesis uses a case study to compare the viability of using direct current instead of alternating current to supply power to 5 buildings in a local energy system (LES). The case study sought to show how using LVDC instead of LVAC could increase the effectiveness of solar panels (PV), batteries and interconnecting buildings into a local energy system (LES). READ MORE
