  1. 1. Local voltage control in a low voltage grid with high photovoltaic penetration

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Joakim Bakklund; [2024]
    Keywords : Technology and Engineering;

    Abstract : This thesis examines how active power control (Volt-Watt control) and reactive power compensation (Volt-VAr control) can help limit voltage increases on the low voltage grid due to high photovoltaic (PV), installations. Due to the large increase in interest to install small scale PV-systems within residential areas the Distribution System Operator E. READ MORE

  3. 2. Regularization Methods and High Dimensional Data: A Comparative Study Based on Frequentist and Bayesian Methods

    University essay from Lunds universitet/Statistiska institutionen

    Author : Markus Gerholm; Johan Sörstadius; [2024]
    Keywords : Linear regression; high dimensional data; regularization; Bayesian methods; Mathematics and Statistics;

    Abstract : As the amount of high dimensional data becomes increasingly accessible and common, the need for reliable methods to combat problems such as overfitting and multicollinearity increases. Models need to be able to manage large data sets where predictor variables often outnumber the amount of observations. READ MORE

  4. 3. A Hierarchical Tucker Solver for the Vlasov-Maxwell System

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Oskar Tegby; [2023]
    Keywords : ;

    Abstract : The Vlasov-Maxwell equations is a common model to describe the behavior of a plasma, but come at the cost of their dimensionality since both spatial and veloocity data is stored in three dimensions. This causes a significant obstacle to be able solve them numerically since the size of the data is N^6, which yields a data size of 8. READ MORE

  5. 4. Second Home, New Home

    University essay from KTH/Samhällsplanering och miljö

    Author : Minghui Li; [2023]
    Keywords : urban village; urban regeneration; informal employment migrants; public space;

    Abstract : As a unique form of rural-urban transition settlement in China’s rapid urbanization process, the “urban village” plays a very distinctive part in promoting urbanization, being a transit point for many rural people entering urban areas. The term “informal employment migrants” usually refers to those people, who have no formal employment status and work in informal, low-skilled, low-paying jobs in the city. READ MORE

  6. 5. Hydraulic modelling at Finsjö Övre hydropower plant : Study for evaluation of a fishway's attractiveness

    University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Author : Eddie Blomström; [2022]
    Keywords : fishway; flow; hydraulics; HEC-RAS;

    Abstract : In connection with the government’s approval on the proposed national plan (NAP) in 2019, it has become highly topical to find solutions problems regarding fish migration in Swedish watercourses. At Finsjö Övre hydropower plant in Emån, a new type of fishway is planned to be installed and evaluated starting at the end of 2022. READ MORE
