  1. 16. Application of harmonic injection method to analyse Sub-Synchronous Control Interactions (SSCI)

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

    Author : Linus Eriksson; [2022]
    Keywords : Sub-synchronous control interaction SSCI ; damping of SSCI; DFIG; PSCAD; Power Oscillation Damper POD ; Harmonic Injection; Subsynkrona kontrollinteraktioner SSCI ; dämpning av SSCI; DFIG; PSCAD; Dämptillsats POD ; Harmonisk Injection;

    Abstract : Wind farms are commonly connected to the main grid through compensated lines which increases the power transfer capability of the line. Double Fed Induction Generator (DFIG) wind turbines in connection to compensated lines can experience Sub-Synchronous Control Interaction (SSCI) which can bring system quantities above allowed levels.

  3. 17. Understanding the pathophysiology ofrecurrent UBTF mutations associated withpediatric AML

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Annie Paulsson; [2022]
    Keywords : Hematologi; Cancer; AML; UBTF; leukemi;

    Abstract : Acute myeloid leukaemia (AML) is highly heterogeneous haematological malignancy, which represents a challenge in the understanding of the disease. Relapse in AML is common, andmany relapsed patients respond poorly to conventional treatment, leading to a low survivalrate. READ MORE

    Abstract : The rate of degradation of a lithium-ion battery depends on its use i.e. how it is charged and discharged. Physics-based models are used to represent the processes inside a cell as well as the degradation mechanisms. READ MORE

  5. 19. Accelerated Testing of the End-plate Assembly of a Redox Flow Battery

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Saksham Jindal; [2022]
    Keywords : Energy Storage; Flow Batteries; Accelerated Testing; Contact Resistance; Endplate Assembly; Leak Rate; Stack Design; Energilagring; flödesbatterier; accelererad provning; kontaktmotstånd; montering av ändplattor; läckagehastighet; utformning av staplar.;

    Abstract : As the world transitions to intermittent renewable energy sources like solar and wind, the need for long-duration energy storage technologies is becoming more and more prominent. In this regard, flow batteries are seen as a promising solution, owing to their inherent advantages like decoupling of power and energy, extremely high cycle life and negligible self-discharge.

  6. 20. Transformation towards strategic procurement : A multiple case study of companies undergoing a procurement transformation

    University essay from Linköpings universitet/Industriell ekonomi

    Author : Frida Bergman; Jennifer Lindegren; [2022]
    Keywords : transformation; procurement; strategic procurement; procurement transformation; internal conditions.;

    Abstract : The global business context has created an increased need for procurement to become strategic. Strategic procurement revolves around integrating procurement with the rest of the company and ensuring that its goals are in line with the company’s objectives. Strategic procurement requires it to be included in strategic planning and implementation. READ MORE
