16. Frequency Response from Inverter-Based Generation
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : The system inertia of the Nordic power system is expected decrease in the future. This is due to an expected reduction in synchronous generation from nuclear and thermal power. This will be compensated by an increase in power from inverter-based generation due to wind power’s expansion in the power system. LÄS MER
17. Stroller Service System : How to make customer products sustainable within the planetary boundaries - using the case product ‘stroller’, PSS and a Design Thinking approach
Master-uppsats, Linköpings universitet/MaskinkonstruktionSammanfattning : Physical customer products have an environmental impact, such as greenhouse gas emissions, due to the use of virgin resources from cradle-to-grave, especially when the origin of the material is from fossil resources. This thesis aims to create a circular business model, by investigating the product ‘stroller’ and place it in a Product Service System, where the user subscribes to the Stroller Service System.

19. Elkvalitetspåverkan vid utlokaliserad felbortkoppling i radiella 40 kV distributionsnät
Uppsats för yrkesexamina på grundnivå, Högskolan Väst/Avdelningen för Industriell ekonomi, Elektro- och MaskinteknikSammanfattning : Detta examensarbete betraktar elkvalitetspåverkan som kan uppkomma till följd av att reläskydd och brytare utlokaliseras i ett kraftnät med radiell drift. Rapporten lyfter fram den potentiella problematiken som kan uppkomma på grund av ett förlängt frånkopplingsförhållande, förhållandet mellan spänningsdippens djup och dess korresponderande felbortkopplingstid, vid feltillstånd i nätet.
