  1. 21. Convolutions on graphs for learning vehicle crash behaviour

    University essay from Göteborgs universitet/Institutionen för data- och informationsteknik

    Author : Daniel Adin; [2021-11-09]
    Keywords : Computer; science; computer science; engineering; graph; convolutions; inite element method; project; thesis;

    Abstract : Convolutional Neural Networks (CNN) have shown successful results in the recent years, especially within the area of image analysis. The idea of learning to predict the result of a crash simulation using machine learning rose from the analogy between images and Finite Element models (FE-models) used in crash simulations.

    Abstract : In Sweden, there is a strong and growing interest in solar power. In recent years, photovoltaic (PV) system installations have increased dramatically and a large part are distributed grid connected PV systems i.e. rooftop installations. READ MORE

  4. 23. Voltage Deviations in a Power System

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

    Author : Klas Lindgren; Sophia Larbi Engelbrektsson; [2021]
    Keywords : MATPOWER; Voltage Deviations; Power Flow; Power System; Wind Power; Resiliency;

    Abstract : The aim of this project was to analyze howthe voltage magnitudes of an electrical grid is affectedwhen wind power production varies in an area aroundthe river of Ångermanälven. The goal of the project wasto keep the voltage deviation within 10 % from the setbase value. READ MORE

  5. 24. The value of flexibility in a future electric power distribution system

    University essay from Uppsala universitet/Industriell teknik

    Author : Elias Moberg; [2021]
    Keywords : Power distribution; Flexibility; Distributed energy resources; Smart grids;

    Abstract : The size and composition of the Swedish electricity generation are changing. This, in combination with new legal requirements from regulatory entities including the EU Directive 2019/944, creates several challenges for the design of the future system. READ MORE

  6. 25. Open Source Grid Expansion Models for the EU Project Spine

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

    Author : Akshaya Tammanur Ravi; [2021]
    Keywords : Expansion Planning; Renewable Energy Sources; Operational Variability; Representative Days; Long-term Uncertainties; Stochastic Optimization; Utbyggnadsplanering; Förnybara energikällor; Variabel driftsituation; Representativa dagar; Långsiktiga osäkerheter; Stokastisk optimering;

    Abstract : Modern power systems are at the forefront of addressing the transition towards a decarbonized energy system, with increased integration of renewable energy sources becoming the key means to achieve the same. In this context, an expansion planning problem provides a decision support framework for investments in new generation and transmission assets over a long time-frame, addressing a wide range of technical and economic criteria aligned with national policies.
