  1. 1. The effect of recycling and processing routes on recrystallization in a secondary 3xxx aluminium alloy

    University essay from Jönköping University/JTH, Material och tillverkning

    Author : Anton Rolseth; [2023]
    Keywords : Aluminium alloys; sheet metal forming; grain boundary segregation; recrystallization; Zener pinning; casting; rolling;

    Abstract : Aluminium alloys have the possibility to be infinitely recycled. By only generating 5% of the emissions compared to primary aluminium, great CO2 savings can be made. One of the issues in manufacturing components entirely from post-consumer scrap is the presence of trace elements and impurities. Such elements can be Fe, Cu, Cr, P and Pb. READ MORE

  3. 2. Parallel Operation of Grid-Forming Power Inverters

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

    Author : Alessia Camboni; [2023]
    Keywords : ;

    Abstract : The use of renewable energy sources has been increasing during the last few years, both to obtain a less impacting energy production, and because of the limited fossil resources. Renewable sources are connected to the grid using inverters, which can be controlled in two main modes, grid-following, and grid-forming. READ MORE

  4. 3. Relay settings for frequency derivative protection against islanding : Optimizing RoCoF-Hysteresis and Delay for the Swedish power grid: An investigation of relevant values

    University essay from KTH/Hälsoinformatik och logistik

    Author : Ahmad Safari; [2023]
    Keywords : Islanding; unintentional islanding; distributed energy resources; main grid; RoCoF; hysteresis; delay; Ödrift; oavsiktlig ödrift; distribuerade energiresurser; stamnät; RoCoF; hysteres; fördröjning;

    Abstract : This report addresses the parameter settings for a protective relay designed to safeguard a 15 kW wind turbine located in Rimbo, Norrtälje municipality, against unintentional islanding. This type of situation arises when distributed energy resources continue to supply local loads, even if the main grid has been unintentionally disconnected. READ MORE

  5. 4. Powering up profits - Integrating Power Purchase Agreements and Battery Systems for Nordic Power Futures

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : William Thorwaldson; Ellen Jinglöv; [2023]
    Keywords : Power Purchase Agreements; Financial Power Trading; Battery Energy Storage Systems; Power Futures; Technology and Engineering;

    Abstract : This master’s thesis aims to assess the profitability and the factors impacting the profitability of entering a short position in financial derivative contracts on the Nordic power market while procuring electricity through a pay-as-produced power purchase contract and on the day-ahead (DA) market, simultaneously the strategy utilizes a battery storage system to mitigate the effects of price spikes. The research adopted a mixed-method approach by combining quantitative analysis with qualitative findings. READ MORE
