  1. 1. Aggregation of Solar and Wind Power and its Impact on the Development of the Transmission Network : KTH Thesis Report

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

    Author : Emma Juserius; Filippa Ström; [2023]
    Keywords : Aggregation between solar and wind; Coincident factor; Correlation coefficient; Hybrid park; Smoothing effects; Solar PV; Wind power generation; Hybridpark; Korrelations koefficient; Sammanlagring av sol och vindkraft; Solkraft; Utjämnings effekt; Vindkraft;

    Abstract : Variable renewable energy (VRE) is becoming more present in the energy mix as society aims to shift power production from fossil fuels. Solar and wind power are VRE sources, which can result in fluctuations in the input to the network, creating supply uncertainty. READ MORE

  3. 2. Investigation of charge injection at electrode-dielectric interface relevant for HVDC cables : Simulation of charge injection and transport dynamics in electrical insulation for HVDC cables

    University essay from Uppsala universitet/Tillämpad mekanik

    Author : Mohammed Mosa; [2023]
    Keywords : BCT model; charge injection; space charge density; electric field distribution; Fowler-Nordheim; Richardson-Schottky;

    Abstract : A bipolar charge transport (BCT) model is used to simulate charge injection and transportdynamics inside insulation material which are used in a high voltage direct current (HVDC)cable. Gaining knowledge about space charge density and electric field distribution in theinsulation material enables minimising charge injection at the metal-insulator interface andavoiding unnecessary energy loss.

    University essay from Uppsala universitet/Tillämpad mekanik

    Author : Luc Villibord; [2023]
    Keywords : ;

    Abstract : Power Transformers are an important and complex part of the electrical transmission technology. One of the main producers of these transformers worldwide is Hitachi Energy, for which this work has been done. READ MORE

  5. 4. Utilization of Rubber and Plastic Waste as  A Partial Replacement of Aggregate for  Improved Sound Insulation

    University essay from Luleå tekniska universitet/Arkitektur och vatten

    Author : Nooralhuda Chabuk; [2022]
    Keywords : concrete; rubber; plastic. PET; insulation.;

    Abstract : Globally, billions of tons of rubber and plastic waste are produced annually, and because these wastes degrade so slowly (about 450 years for plastic bottles and 80 years for tire rubbers), they are extremely difficult to dispose of. As a result, utilizing these wastes directly in building materials can significantly reduce the environmental load while also increasing the sustainability of the building material. READ MORE

  6. 5. Atmospheric Attenuation for Lidar Systems in Adverse Weather Conditions

    University essay from Umeå universitet/Institutionen för fysik

    Author : Johan Viklund; [2021]
    Keywords : Lidar; Lidar equation; Extinction coefficient; Signal attenuation;

    Abstract : In this study, the weather impact on lidar signals has been researched. A lidar system was placed with a target at approximately 90 m and has together with a weather station collected data for about a year before this study. READ MORE
