  1. 1. HfO2 and ITO Resistive Random-Access Memory

    Master-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Författare :Mattias Åstrand; [2020]
    Nyckelord :RRAM; Resistive switching; HfO2; ITO; Physics and Astronomy;

    Sammanfattning : The purpose of this work is of evaluating the choice of HfO2 and ITO as the dielectric and the top electrode in high performance resistive random-access memory (RRAM), respectively. The study is twofold, as it quantifies performance according to standard figures of merit for this technology, as well as provides insight into the physics of current conduction for this material choice.

  3. 2. People on the same boat should help each other: A Feasibility Assessment for an Offshore Wind Accelerator (OWA) in China

    Master-uppsats, Lunds universitet/Internationella miljöinstitutet

    Författare :Xuan Xie; [2019]
    Nyckelord :Offshore Wind; Innovation; Collaboration; Feasibility Assessment; China’s Power Sector; SOEs; Social Sciences;

    Sammanfattning : Facing the challenges of climate change and energy depletion, the world needs to deploy more renewable energy to replace fossil fuels. As the largest energy consumer and carbon emitter, China’s sustainable energy transition is particularly important. LÄS MER

  4. 3. Reactive power management capabilities of Swedish sub-transmission and medium voltage level grid

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Michal Tomaszewski; [2018]
    Nyckelord :electric power systems; reactive power; sub-transmission level grids; PSS E; power ow analysis; wind farms; smart grids; droop control; elektriska system; reaktiv eekt; mellan spanningsnivan; PSS E; strom odesanalys; vindkraftparker; smarta nat; droop control;

    Sammanfattning : Rising penetration of renewable energy sources in electric power grids isboth a challenge and an opportunity to optimally utilize the potential of eitherwind or PV energy sources, to stabilize operation of future power systems.Bi-directional ows between distribution and transmission system operatorscause signicant problems with keeping the voltages in the grid within admissiblelimits.

  5. 4. Undersökning av akustiskaegenskaper hos ett insugningssystem

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Martin Nordenström; Rodrigue Bonnevie; [2018]
    Nyckelord :;

    Sammanfattning : En viktig del i arbetet med att konstruera tysta fordon är kännedomen om komponenternas akustiska egenskaper. I projektet har ett insugningssystem till en lastbil från Scania undersökts, och utstrålad ljudintensitet och ljudeffekt för olika delytor på systemet uppmätts. LÄS MER

  7. 5. Formulation of the power flow problem in human readable form for translation into an efficient solver

    Master-uppsats, KTH/Skolan för elektro- och systemteknik (EES)

    Författare :Muhammad Talal Khan; [2016]
    Nyckelord :;

    Sammanfattning : Power systems are complex systems that need supervision and control to operatereliably and safely. Energy Management Systems (EMS)/SCADA provides the necessary aids formonitoring and control of power systems. Since power ow forms the basis of power system analysis,power ow solvers (PFS) are an integral part of EMS/SCADA systems. LÄS MER
