  1. 1. Comparing Different Approaches for Solving Large Scale Power Flow Problems on the CPU and GPU with the Newton-Raphson Method

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Manolo D'Orto; [2020]
    Nyckelord :;

    Sammanfattning : Power system modelling is increasing in importance. It is vital for power system operations and transmission grid expansions, and therefore the future energy transition. The Swedish power system is under fast development to face the progress of more flexible demand, a higher share of distributed renewable sources, and updated capacities. LÄS MER

  3. 2. A comparative study of IEEE 754 32-bit Float and Posit 32-bit floating point format on precision. : Using numerical methods.

    Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Johan Besseling; Anders Renström; [2020]
    Nyckelord :;

    Sammanfattning : Posit is a new way of representing floating points in computers. This thesis investigates the precision of the 32-bit Posit floating point format compared to the current standard 32-bit IEEE 754 Float format by conducting tests with numerical methods. Posit was chosen due to its promising results in previous work. LÄS MER

  4. 3. Algebraiska och geometriska lösningar av kubiska ekvationer

    Kandidat-uppsats, Högskolan i Gävle/Avdelningen för elektronik, matematik och naturvetenskap

    Författare :Ihab Megbil; [2018]
    Nyckelord :Geometric algebra; Khayyam method; Cardanos method; equations; cubic equations functions; Alkhawarizmi; Algebra; Geometri; Geometrisk algebra; Cardanos metod; Khayyams metod; Bisektionsmetoden; Newton-Raphsons metod; Eulers metod; Descartes metod; ekvationer; kubiska ekvationer funktioner; Khwarizmi; عمر الخيام الخوارزمي;

    Sammanfattning : Syftet med det här arbetet är att lösa kubiska ekvationer utifrån både algebraiska och geometriska perspektiv. Läsaren kommer att möta olika metoder att finna rötter av kubiska ekvationer med fokus på Cardanos metod. Kapitel 3 introducerar Khayyams metod för att hitta en positiv reell rot med hjälp av geometrisk algebra. LÄS MER

  5. 4. Calibrating the Hull-White model using Adjoint Algorithmic Differentiation

    Master-uppsats, KTH/Matematisk statistik

    Författare :Simon Carmelid; [2017]
    Nyckelord :;

    Sammanfattning : This thesis includes a brief introduction to Adjoint Algorithmic Differentiation (AAD), accompanied by numerical examples, step-by-step explanations and runtime comparisons to a finite difference method. In order to show the applicability of AAD in a stochastic setting, it is also applied in the calculation of the arbitrage free price and partial derivatives of a European call option, where the underlying stock has Geometric Brownian motion dynamics.

  7. 5. Design of power supply system in DC electrified transit railways - Influence of the high voltage network

    Uppsats för yrkesexamina på avancerad nivå, KTH/Elektrisk energiomvandling

    Författare :Denis Seimbille; [2014]
    Nyckelord :railway simulation; electric traction; AC DC load flow; high voltage network;

    Sammanfattning : Urban rail systems such as subways and trams transport millions of people every day, oering a high level of service. Most of these systems are fed by direct current (DC). The design of the power supply network of DC electried transit railways is of great importance and requires the use of simulation models. LÄS MER
