  1. 1. Laststyrning av eluppvärmning och varmvattenberedning : En studie av potentialen för hushåll att bidra till en sänkt abonnerad effekt mot överliggande elnät


    Författare :Niklas Ahlm; [2021]
    Nyckelord :Laststyrning; efterfrågeflexibilitet; flexibilitet; förflyttning av last; eluppvärmning; varmvattenberedning; effekttoppar; abonnerad effekt; överliggande elnät;

    Sammanfattning : This study has explored the potential for lowering the subscripted power of 25 MW for one of the connection points between the local power grid and its overhead power grid for a local grid owner. The potential for doing so through hard, direct load control of electrical domestic heating and domestic water heating for detached houses with a fuse size of 16-25 A is evaluated for 12 different scenarios.

  4. 4. Bridging Sim-to-Real Gap in Offline Reinforcement Learning for Antenna Tilt Control in Cellular Networks

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

    Författare :Mayank Gulati; [2021]
    Nyckelord :reinforcement learning; transfer learning; simulation-to-reality; simulator; realworld; real-world network data; remote electrical tilt optimization; cellular networks; antenna tilt; network optimization.;

    Sammanfattning : Antenna tilt is the angle subtended by the radiation beam and horizontal plane. This angle plays a vital role in determining the coverage and the interference of the network with neighbouring cells and adjacent base stations. LÄS MER

  5. 5. Investigation of Machine Learning Methods for Anomaly Detection and Characterisation of Cable Shoe Pressing Processes

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Elliot Härenby Deak; [2021]
    Nyckelord :Machine Learning; LSTM; kNN; Time-series Classification; Anomaly Detection;

    Sammanfattning : The ability to reliably connect electrical cables is important in many applications. A poor connection can become a fire hazard, so it is important that cables are always appropriately connected. This thesis investigates methods for monitoring of a machine that presses cable connectors onto cables. LÄS MER
