  1. 6. Towards Affordable Sodium-Ion Batteries : Mechanochemical Synthesis and Electrochemical Assessment of Iron-Based Fluorophosphate Cathode Material

    University essay from KTH/Materialvetenskap

    Author : Ratna Juwita; [2023]
    Keywords : Sodium-ion batteries; electrical energy storage EES ; iron oxide; positive electrode; material characterization; electrochemical; discharge capacity.; Natriumjonbatterier; elektrisk energilagring EES ; järnoxid; positiv elektrod; materialkarakterisering; elektrokemisk; urladdningskapacitet;

    Abstract : An urgent transformation from fossil fuels to cleaner energy sources to combat climate change has led to the utilization of renewable energies like solar, wind, and tidal power. However, the intermittency of these sources hinders their wider implementation. To address this, large-scale electrical energy storage (EES) systems are needed. READ MORE

  2. 7. Techno-Economic Optimization and Control of Hybrid Energy Systems

    University essay from Linköpings universitet/Fordonssystem

    Author : Louise Calmered; Tanja Nyberg; [2023]
    Keywords : Hybrid Energy Systems; Optimization; Control Techniques; Peak Shaving; Energy Arbitrage; Ancillary Services;

    Abstract : The increasing demand for renewable energy sources to meet climate targets and reduce carbon emissions poses challenges to the power grid due to their intermittent nature. One potential solution to maintain grid stability is by implementing Hybrid Energy Systems (HESs) that incorporate a Battery Energy Storage System (BESS). READ MORE

  3. 8. Model Development for Wave Energy Converter Arrays in the Frequency Domain

    University essay from Uppsala universitet/Elektricitetslära; Uppsala universitet/Institutionen för fysik och astronomi

    Keywords : Physics; Energy Physics; Energy; Renewable Energy; Wave Power; CorPower Ocean; Point Absorber; Array Modelling; Farm modelling; Fysik; Energifysik; Energi; Vågkraft; Förnyelsebar Energi;

    Abstract : In this thesis, a model has been developed to analyze the behavior of wave energy converter arrays in the frequency domain. This development serves the purpose of establishing an in-house model tool for array modelling for CorPower Ocean. READ MORE

  4. 9. Analysis of a high step-up gain DC-DC converter for fuel cell and battery application

    University essay from Uppsala universitet/Institutionen för elektroteknik

    Author : Kaj Törngren Sato; [2023]
    Keywords : Fuel cell; High step-up DC-DC converter; Boost converter; Coupled inductors; Coupling factor; CCM; DCM; Duty cycle;

    Abstract : In sustainable energy systems those using fuel cells, high step-up gain converters are widely used to increase the output voltage to levels that can be used by other converters, such as inverters for grid connection or powering other AC loads. In order to obtain a higher voltage gain, in comparison to a traditional boost converter, often different topologies techniques are involved. READ MORE

  5. 10. Meteorological Causes for Wind Power Ramps: A Comparison between four sites in Sweden

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Anabelle Engert; [2023]
    Keywords : meteorology; mesoscale; wind energy; wind power ramps;

    Abstract : Wind energy as renewable energy will be crucial in ensuring future energy supply. Foundation for agood implementation of wind power output in the electrical grid are wind forecasts. Especially windpower ramp forecasting is important for an effective generation of wind power energy by wind parks. READ MORE
