  1. 1. Graph theory applications in the energy sector : From the perspective of electric utility companies

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Kristofer Espinosa; Tam Vu; [2020]
    Nyckelord :graph theory; feature selection; energy industry; grafteori; variabelselektering; energiindustri;

    Sammanfattning : Graph theory is a mathematical study of objects and their pairwise relations, also known as nodes and edges. The birth of graph theory is often considered to take place in 1736 when Leonhard Euler tried to solve a problem involving seven bridges of Königsberg in Prussia. LÄS MER

  3. 2. Applications of graph theory in the energy sector, demonstrated with feature selection in electricity price forecasting

    Master-uppsats, KTH/Optimeringslära och systemteori

    Författare :Duc Tam Vu; [2020]
    Nyckelord :Graph theory; feature selection; energy company; Grafteori; variabelselektering; energiföretag;

    Sammanfattning : Graph theory is a mathematical study of objects and their pairwise relations, known as nodes and edges respectively. The birth of graph theory is often considered to take place in 1736 when the Swiss mathematician Leonhard Euler tried to solve a routing problem involving seven bridges of Königsberg in Prussia.

  4. 3. CBA of environmental projects within hydropower

    Master-uppsats, KTH/Energiteknik

    Författare :Sarah Hagman; Julia Lindberg; [2018]
    Nyckelord :;

    Sammanfattning : Hydropower is a fundamental pillar in the Swedish energy system and accounts for a large part of the Swedish electricity production. The regulation power is also essential for balancing the grid load. LÄS MER

  5. 4. Using eDNA to improve environmental monitoring for water bodies effected by hydropower in Sweden

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Elin Hellmér; [2018]
    Nyckelord :eDNA; environment; environmental monitoring; hydropower; index;

    Sammanfattning : The aim of this report is to contribute to the base of knowledge on environmental monitoring by increasing understanding of how eDNA, electrofishing and sampling fishing may be used to examine fish biodiversity. It also aims at understanding if fish indexes developed within the Water Framework Directive reflect biodiversity, as well as the potential of eDNA data to serve as input to these indexes. LÄS MER

  7. 5. Recovery of Phosphorus from Incineration of Sewage Sludge

    Master-uppsats, KTH/Skolan för kemivetenskap (CHE)

    Författare :Aditi Bhasin; [2017]
    Nyckelord :;

    Sammanfattning : The primary source of phosphorus, phosphate rock, is a non-renewable resource which is expected to get exhausted in the next 50 – 100 years. Sewage sludge in Sweden constitutes 25% of the annual phosphorus in the country, making it a potentially significant source for phosphorus recovery. LÄS MER
