  1. 11. 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

  3. 12. THE RE-EMERGENCE OF A PSYCHIATRIC PARADIGM : A SYSTEMATIC REVIEW AND META-ANALYSIS OF THE EFFICACY OF MDMA-ASSISTED AND PSILOCYBIN-ASSISTED PSYCHOTHERAPY FOR PTSD AND MDD

    University essay from Umeå universitet/Institutionen för psykologi

    Author : Andreas Johansson; [2023]
    Keywords : ;

    Abstract : Psychedelic research became throttled in the 1970s, though the clinical interest for psychedelics has seen a resurgence in the last couple of decades for their application as psychotherapy-adjunct substances used to treat various psychological disorders. Primarily mediated through agonism at the serotonin 2a receptor, psychedelics encompass and subsequently effect vast areas of the brain and implicates several limbic structures of relevance for emotional processing.

  4. 13. The effect of material properties on PEM fuel cell catalysts on durable oxidation reduction activity

    University essay from KTH/Kemiteknik

    Author : Xiaoling Jiang; [2023]
    Keywords : PEM fuel cell; catalyst; ORR activity; particle size; degradation; PEM-bränslecell; katalysator; syrgasreduktionsaktivitet; partikelstorlek; åldring;

    Abstract : I detta examensarbete utforskas påverkan av partikelstorleken hos Pt-katalysatorer på kolbärare på syrereduktionen i polymerelektrolytmembran (PEM)-bränsleceller. Den elektrokemiskt aktiva ytarean, aktiviteten för syrereduktion och tillhörande degraderingshastigheter för de undersökta katalysatorerna beräknas och jämförs. READ MORE

  5. 14. Network reconfiguration for renewable generation maximization

    University essay from Lunds universitet/Industriell elektroteknik och automation

    Author : Gabriel Malmer; Lovisa Thorin; [2023]
    Keywords : distributed generation; hosting capacity; network reconfiguration; optimal power flow; power distribution; optimization; mixed-integer programming; Technology and Engineering;

    Abstract : Increasing the amount of renewable generation in distribution networks is a fundamental part of the energy transition. Multiple methods exist to increase the hosting capacity in a grid, to allow larger injections of generation and more efficiently utilize existing infrastructure before operational limits are breached.
