  1. 1. Grey-box Modeling of Hydropower Plants for Improved Frequency Regulation : Evaluation of Double-Regulated Hydropower Turbines for Fulfillment of the New FCR-requirements

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära

    Författare :Karolina Engström; Rebecca Waldenfjord; [2023]
    Nyckelord :Double-regulated hydroturbines; Grey-box modeling; FCR-requriements; Frequency contaminent reserve; Hydropower modeling; Dynamic stability; Dynamic performance;

    Sammanfattning : Over the last decades, the frequency on the Nordic electrical power grid has deteriorated. Therefore, new stricter requirements are developed for the hydropower delivering regulating active power on the Frequency Containment Reserve market (FCR). LÄS MER

  3. 2. Investigating and Modeling Uplink Processing in 5G NR Multisector Scheduler Simulator

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Oskar Nygren; Axel Sneitz-Björkman; [2022]
    Nyckelord :Technology and Engineering;

    Sammanfattning : As the latest generation of wireless access technology called Fifth Generation (5G) New Radio (NR) evolves, computational efficiency is key to keep low cost and flexible deployments for vendors. Understanding how the Digital Signal Processing (DSP) load behaves in the digital units is one aspect to enable this efficiency. LÄS MER

  4. 3. Linear parameter varying model and identification method for Li-ion batteries in electric vehicles

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för systemteknik

    Författare :Per Larsson; [2021]
    Nyckelord :batteries; system identification; linear parameter varying model;

    Sammanfattning : The market for electric vehicles (EV) is growing rapidly. The rise of EVs is most prominent for passenger vehicles, but trucks and busses are also quickly becoming electrified. Scania aims to be the leader of this transition. A central part of the EV is the Lithium-ion battery. LÄS MER

  5. 4. Modelling stellar streams around the Milky Way

    Master-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation

    Författare :Hyerin Jang; [2021]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : Stellar streams around the Milky Way (MW) have been observed by wide sky surveys, and studied to understand the mass distribution of the MW. This is because streams are formed by a disruption of a globular cluster or a dwarf galaxy under the influence of the gravitational field of the MW. LÄS MER

  7. 5. Learning-Based Motion Planning and Control of a UGV With Unknown and Changing Dynamics

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Åke Johansson; Joel Wikner; [2021]
    Nyckelord :machine learning; model predictive control; motion planning; Bayesian linear regression; motion primitives; input sampling; hybrid A*;

    Sammanfattning : Research about unmanned ground vehicles (UGVs) has received an increased amount of attention in recent years, partly due to the many applications of UGVs in areas where it is inconvenient or impossible to have human operators, such as in mines or urban search and rescue. Two closely linked problems that arise when developing such vehicles are motion planning and control of the UGV. LÄS MER
