  1. 6. Benchmarking of Smart Grid Conceptsin Low-Voltage Distribution Grids

    Master-uppsats, KTH/Kraft- och värmeteknologi

    Författare :Odilia Bertetti; [2017]
    Nyckelord :Smart Grid; Grid Integration; Distributed Generation; Electric Vehicles; Photovoltaic; Battery Storage; Heat Pump; Flexibility; DigSILENT PowerFactory.; Smart Grid; Nätintegration; Distribuerad Generation; Elfordon; Solceller; Batterilagring; Värmepump; Flexibilitet; DigSILENT PowerFactory;

    Sammanfattning : Due to increasing penetration of decentralized variable renewable energy generators and the increasing demand of electrical power due to the electrification of the heat and transport sectors, low voltage grids are facing critical problems. Deviation of the permitted voltage range and local overloads of the grid equipment, are the two main issues that are compromising a smooth distribution grid operation. LÄS MER

  2. 7. Reaktiv effektkompensering : Kartläggning och utvärdering av olika lösningar för att kompensera reaktivt effekt i vindkraftparker

    Uppsats för yrkesexamina på grundnivå, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Författare :Per Storgärd; [2015]
    Nyckelord :Reaktiv effekt; Elkvalité; Energi; Vindkraft;

    Sammanfattning : I takt med en utbyggnad av vindkraften i Sverige ökar också risken för minskad elkvalité. Vindkraften ger upphov till ett flertal störningar som riskerar minska elkvalitén på det svenska kraftnätet. LÄS MER
