  1. 21. EV Fleet Flexibility Estimation on the Distribution Network

    Master-uppsats, KTH/Energiteknik

    Författare :Bilal Fares; [2020]
    Nyckelord :;

    Sammanfattning : A new electricity market model was drafted in Denmark (1) to define the roles of different players and promote the integration of renewable generation as well as the gradual shift towards smartgrids. Along with a clear political will and adjustments of some regulatory barriers, this potentiallyopens the market for an increased share in electric vehicles (EVs). LÄS MER

  4. 23. Tackling imbalanced data in Random Forest to predict free-to-fee transitions of a subscription SaaS-application

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

    Författare :Anna Karlhede; [2020]
    Nyckelord :;

    Sammanfattning : In this thesis we investigate different methods to tackle imbalanced data when using Random Forest for classification. The data comes from a subscription SaaS-application, namely Mentimeter, which allows users to create interactive presentations. LÄS MER

  5. 24. Material Transfer Mechanisms during Interaction of Aluminium Alloy and Tool Steel at Elevated Temperatures

    Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Gabriel Macêdo; [2020]
    Nyckelord :material transfer mechanisms; high temperature tribology; hot metal forming tribology; hot-stamping of aluminium alloys; aluminium alloys;

    Sammanfattning : Hot stamping of aluminium alloys allows for increased formability, decreased springback and the possibility of integrating age-hardening heat treatments into the process. However, it can be challenging due to the occurrence of material transfer of aluminium onto the tool, as aluminium is prone to adhesion even at low temperatures. LÄS MER

  7. 25. Improved planning of wind farms using dynamic transformer rating

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

    Författare :Andrea Molina Gómez; [2020]
    Nyckelord :Dynamic transformer rating; wind energy; loss of life; mixed-integer linear programming; wind farm planning.; Dynamisk lastbarhet hos transformatorer; vindkraft; livstidsförlust; mixed-integer linear programming; vindkraftsparksplanering;

    Sammanfattning : Due to the increase in electrical demand and renewable penetration, electrical utilities need to improve and optimize the grid infrastructure. Fundamental components in this grid infrastructure are transformers, which are designed conservatively on the base of a static rated power. LÄS MER
